Conventions
 
We have translated amounts from Renminbi into U.S. dollars solely for the convenience of the reader at the noon buying rate for cable transfers in Renminbi as certified for customs purposes by the Federal Reserve Bank of New York on December 31, 2007 of US$1.00=Rmb 7.2946.  We have also translated amounts in Hong Kong dollars solely for the convenience of the reader at the noon buying rate for cable transfers in Hong Kong dollars as certified for customs purposes by the Federal Reserve Bank of New York on December 31, 2007 of HK$7.7984 to US$1.00.  We make no representation that the Renminbi amounts or Hong Kong dollar amounts could have been, or could be, converted into U.S. dollars at those rates on December 31, 2007, or at all.  For further information on exchange rates, see “Item 3—Key Information—Selected Financial Data.”
 
Totals presented in this annual report may not total correctly due to rounding of numbers.
 
Our “average net realized price” for oil and gas in each period is derived from a numerator divided by a denominator, where:
 
 
·
the numerator is equal to the sum of (i) revenues from our oil and gas sales offshore China for the applicable period; (ii) the 30% ownership share of revenues from gas sales for the applicable period from an unconsolidated investee; and (iii) the revenues from oil and gas sales for the applicable period from our overseas interests; and
 
 
·
the denominator is equal to the sum of (i) the volume of oil and gas sales offshore China for the applicable period; (ii) 30% of the volume of gas sales for the applicable period from an unconsolidated investee; and (iii) the volume of oil and gas sales for the applicable period from our overseas interests.
 
3

 
 
Except as otherwise noted, all information in this annual report relating to our oil and natural gas reserves is based upon estimates prepared by us.  In calculating barrels-of-oil equivalent amounts, we have assumed that 6,000 cubic feet of natural gas equals one BOE, with the exception of natural gas from certain fields which is converted using the actual heating value of the natural gas.
 
Unless otherwise noted, all operating data presented in this annual report, including reserve and production information, includes our interest in the oil and gas field held by an unconsolidated investee in which we hold a 30% equity interest.  For more information on our reserves and related information, see “Supplementary Information on Oil and Gas Producing Activities” in our consolidated financial statements included elsewhere in this annual report, in which we separately disclose reserve and related information for this unconsolidated investee in accordance with U.S. Statement of Financial Accounting Standards No. 69, “Disclosures about Oil and Gas Producing Activities.”
 
Glossary of Technical Terms
 
Unless otherwise indicated in the context, references to:
 
 
·
“API gravity” means the American Petroleum Institute’s scale for specific gravity for liquid hydrocarbons, measured in degrees.  The lower the API gravity, the heavier the liquid and, generally, the lower its commercial value.  For example, asphalt has an API gravity of eight degrees, West Texas Intermediate, a benchmark crude oil, has an API of 40 degrees, and gasoline has an API gravity of 50 degrees.
 
 
·
“appraisal well” means an exploration well drilled after a successful wildcat well to gain more information on a newly discovered oil or gas reserve.
 
 
·
“condensate” means light hydrocarbon liquids separated from natural gas in the field through condensation when natural gas is exposed to surface temperature and pressure.  This group generally includes slightly heavier hydrocarbons than natural gas liquids, such as pentane.  It is combined with crude oil production and reserve figures.
 
 
·
“crude oil” means crude oil and liquids, including condensate, natural gas liquids and liquefied petroleum gas.
 
 
·
“LNG” means liquefied natural gas.
 
 
·
“dry hole” means an exploration well that is not commercial (i.e., economically feasible to develop).  Dry hole costs include the full costs for such drilling and are charged as an expense.
 
 
·
“exploration well” means a wildcat or appraisal well.
 
 
·
“natural gas liquids” means light hydrocarbons that can be extracted in liquid form from natural gas through special separation plants.  This group includes typically lighter liquid hydrocarbons than condensate, such as butane, propane and ethane.  It is combined with crude oil production but not with crude oil reserve figures.
 
 
·
“net wells” means a party’s working interest in wells.
 
 
·
“proved developed reserves” means reserves that can be expected to be recovered through existing wells with existing equipment and operating methods.  Additional oil and gas expected to be obtained through the application of fluid injection or other improved recovery techniques for supplementing the natural forces and mechanisms of primary recovery are included as “proved developed reserves” only after testing by a pilot project or after the operation of an installed program has confirmed through production response that increased recovery will be achieved.
 
4

 
 
 
·
“proved reserves” means the estimated quantities of crude oil, natural gas, and natural gas liquids which geological and engineering data demonstrate with reasonable certainty to be recoverable in future years from known reservoirs under existing economic and operating conditions, i.e., prices and costs as of the date the estimate is made.  Prices include consideration of changes in existing prices provided only by contractual arrangements, but not on escalations based upon future conditions.
 
(i) Reservoirs are considered proved if economic producibility is supported by either actual production or conclusive formation test.  The area of a reservoir considered proved includes:

(A) that portion delineated by drilling and defined by gas-oil and/or oil-water contacts, if any; and

(B) the immediately adjoining portions not yet drilled, but which can be reasonably judged as economically productive on the basis of available geological and engineering data.  In the absence of information on fluid contacts, the lowest known structural occurrence of hydrocarbons controls the lower proved limit of the reservoir.

(ii) Reserves which can be produced economically through application of improved recovery techniques (such as fluid injection) are included in the “proved” classification when successful testing by a pilot project, or the operation of an installed program in the reservoir, provides support for the engineering analysis on which the project or program was based.

(iii) Estimates of proved reserves do not include the following:

(A) oil that may become available from known reservoirs but is classified separately as “indicated additional reserves;”

(B) crude oil, natural gas, and natural gas liquids, the recovery of which is subject to reasonable doubt because of uncertainty as to geology, reservoir characteristics, or economic factors;

(C) crude oil, natural gas, and natural gas liquids, that may occur in undrilled prospects; and

(D) crude oil, natural gas, and natural gas liquids, that may be recovered from oil shales, coal, gilsonite and other such sources.
 
 
·
“proved undeveloped reserves” means reserves that are expected to be recovered from new wells on undrilled acreage, or from existing wells where a relatively major expenditure is required for recompletion.  Reserves on undrilled acreage is limited to those drilling units offsetting productive units that are reasonably certain of production when drilled.  Proved reserves for other undrilled units can be claimed only where it can be demonstrated with certainty that there is continuity of production from the existing productive formation.  Estimates for proved undeveloped reserves are not attributable to any acreage for which an application of fluid injection or other improved recovery technique is contemplated, unless such techniques have been proved effective by actual tests in the area and in the same reservoir.
 
 
·
“share oil” means the portion of production that must be allocated to the relevant government entity or company under our production sharing contracts.
 
5

 
For further definitions relating to reserves:
 
 
·
“reserve replacement ratio” means, for a given year, total additions to proved reserves, which consist of additions from purchases, discoveries and extensions and revisions of prior reserve estimates, divided by production during the year.  Reserve additions used in this calculation are proved developed and proved undeveloped reserves; unproved reserve additions are not used.  Data used in the calculation of reserve replacement ratio is derived directly from the reserve quantity reconciliation prepared in accordance with paragraph 11 of U.S. Statement of Financial Accounting Standards No. 69, which reconciliation is included in “Supplementary Information on Oil and Gas Producing Activities” beginning on page S-1 of this annual report.  However, the reserve replacement ratios included in this annual report also include the reserve additions and production of an investee company accounted for by us using the equity method, which were not included in the reconciliation found in “Supplementary Information on Oil and Gas Producing Activities.”  In 2005, 2006 and 2007, including the reserve additions and production of this investee company did not have a material impact on our reserve replacement ratio.
 
 
Our reserve replacement ratio reflects our ability to replace proved reserves.  A rate higher than 100% indicates that more reserves were added than produced in the period.  However, this measure has limitations, including its predictive and comparative value.  Reserve replacement ratio measures past performance only and fluctuates from year to year due to differences in the extent and timing of new discoveries and acquisitions.  It is also not an indicator of profitability because it does not reflect the cost or timing of future production of reserve additions.  It does not distinguish between reserve additions that are developed and those that will require additional time and funding to develop.  As such, reserve replacement ratio is only one of the indices used by our management in formulating its acquisition, exploration and development plans.
 
 
·
“reserve-to-production ratio” means the ratio of proved reserves to annual production of crude oil or, with respect to natural gas, to wellhead production excluding flared gas.
 
 
·
“seismic data” means data recorded in either two-dimensional (2D) or three-dimensional (3D) form from sound wave reflections off of subsurface geology.  This is usually used to understand and map geological structures for exploratory purposes to predict the location of undiscovered reserves.
 
 
·
“success” means a discovery of oil or gas by an exploration well.  Such an exploration well is a successful well and is also known as a discovery.  A successful well is commercial, which means there are enough hydrocarbon deposits discovered for economical recovery.
 
 
·
“success rate” means the total number of successful exploration wells divided by the total number of exploration wells drilled in a given period.  Success rate can be applied to wildcat wells or appraisal wells in general.
 
 
·
“wildcat well” means an exploration well drilled in an area or rock formation that has no known reserves or previous discoveries.

The words “believe,” “intend,” “expect,” “anticipate,” “project,” “estimate,” “plan,” “predict” and similar expressions are also intended to identify such forward-looking statements.
 
These forward-looking statements address, among others, such issues as:
 
 
·
the amount and nature of future exploration, development and other capital expenditures,
 
 
·
wells to be drilled or reworked,
 
 
·
oil and gas prices and demand,
 
 
·
future earnings and cash flow,
 
 
·

(a)
On March 17, 2004, our shareholders approved a five-for-one stock split of our shares.  The stock split was effected by dividing each of our issued and unissued shares of HK$0.10 each into five shares of HK$0.02 each, and by increasing the board lot size for trading on the Hong Kong Stock Exchange from 500 shares of HK$0.10 each to 1,000 subdivided shares of HK$0.02 each.  The ratio of our ADSs listed on the New York Stock Exchange also changed such that each ADS now represents 100 subdivided shares of HK$0.02 each, as opposed to 20 shares of HK$0.10 each prior to the stock split.  As such, per share amounts of our shares have been adjusted retroactively for the stock split.
 
(b)
Earnings per share (basic) and earnings per ADS (basic) for each year from 2003 to 2007 have been computed, without considering the dilutive effect of the shares underlying our share option schemes and, as applicable, convertible bonds, by dividing profit by the weighted average number of shares and the weighted average number of ADSs of 41,070,828,275 and 410,708,283 respectively for 2003, 41,060,240,659 and 410,602,407 respectively for 2004, 41,054,499,982 and 410,545,000 respectively for 2005, 42,512,190,394 and 425,121,904 respectively for 2006 and 43,605,437,212 and 436,054,372 respectively for 2007, in each case based on a ratio of 100 shares to one ADS.
 
(c)
Earnings per share (diluted) and earnings per ADS (diluted) for each year from 2003 to 2007 have been computed, after considering the dilutive effect of the shares underlying our share option schemes and, as applicable, convertible bonds, by using 41,110,339,095 shares and 411,103,391 ADSs for 2003, 41,179,513,436 shares and 411,795,134 ADSs for 2004, 42,386,055,766 shares and 423,860,558 ADSs for 2005, 42,577,841,013 shares and 425,778,410 ADSs for 2006 and 43,731,936,869 shares and 437,319,369 ADSs for 2007.  For the years 2006 and 2007, the convertible bonds had an anti-dilutive effect on the basic earnings per share and were ignored in the calculation of diluted earnings per share.
 
(d)
The proposed final dividend and special final dividend for 2003 were cancelled and replaced by the special interim dividend of HK$0.06 per share declared and paid in 2004.
 
(e)
For the purposes of this chart, the exchange rate used for the conversion of dividends from Renminbi into U.S. Dollars is the noon buying rate for cable transfers in Renminbi as certified for customs purposes by the Federal Reserve Bank of New York on the last business day of the year for which the applicable dividend was issued.
 
(f)
In periods prior to 2005, no recognition and measurement of share-based transactions in which employees (including directors) were granted share options in our company were required until such options were exercised by the employees, at which time the share capital and share premium were credited with the proceeds received.  In 2005, we adopted the provisions of Hong Kong Financial Reporting Standard (“HKFRS”) retrospectively to all stock options granted from the date of our incorporation.  Under HKFRS 2, when employees (including directors) render services as consideration for equity transactions (“equity-settled transaction”), the cost of equity-settled transaction is measured by reference to the fair value on the date on which the instrument is granted.
 
(g)
In 2005, we restated certain prior year amounts upon adoption of new Hong Kong accounting policies.  For example, in prior periods, we classified the on-shore processing plants as land and buildings and depreciated over 30-50 years on a straight-line basis.  Upon the adoption of HKAS 16, we have retrospectively reclassified our property, plant and equipment into two categories: oil and gas properties, and vehicles and office equipment.  We have reclassified the onshore terminals previously classified as land and buildings to oil and gas properties as they will be used in similar operations and are expected to have similar economic useful lives.  We also changed our accounting policy retrospectively for 2003 and 2004 to state the onshore terminals at cost instead of valuation and to amortize those terminals by the unit-of-production method on a property-by-property basis.

Risks relating to our business
 
Our business, revenues and profits fluctuate with changes in oil and gas prices
 
Even relatively modest declines in crude oil prices may adversely affect our business, revenues and profits.  Our profitability is determined in large part by the difference between the prices received for the crude oil we produce and the costs of exploring for, developing, producing and selling these products.
 
13

 
Prices for crude oil fluctuate widely in response to relatively minor changes in the supply and demand for oil, market uncertainty and various other factors that are beyond our control, including:
 
 
·
political developments in petroleum producing regions;
 
 
·
the ability of the Organization of Petroleum Exporting Countries and other petroleum producing nations to set and maintain production levels and prices;
 
 
·
the price and availability of other energy sources, such as coal;
 
 
·
domestic and foreign government regulations;
 
 
·
weather conditions; and
 
 
·
overall economic conditions.
 
Our revenues and profit have increased significantly in recent years, mainly due to increasing oil prices. However, we cannot assure that oil prices will remain high in the future.
 
The prices for the natural gas we sell are determined by negotiations between us and the prospective buyers.  Our typical contracts with gas buyers include provisions for periodic resets and adjustment formulas that depend on a basket of crude oil prices and inflation as well as various other factors.  These resets and adjustment formulas can result in natural gas price fluctuations which may adversely affect our business, results of operations and financial condition.
 
Lower oil and gas prices may result in the write-off of higher cost reserves and other assets and may lower our earnings or cause losses.  Lower oil and natural gas prices may also reduce the amount of oil and natural gas we can produce economically and render existing contracts that we have entered into uneconomical.  For further details regarding the effects of oil and gas price fluctuations on our financial condition and results of operations, see “Item 5—Operating and Financial Review and Prospects.”
 
The oil and gas reserve estimates in this annual report may require substantial revision as a result of future drilling, testing and production
 
The reliability of reserves estimates depends on a number of factors, including:
 
 
·
the quality and quantity of technical and economic data;
 
 
·
the prevailing oil and gas prices for our production;
 
 
·
the production performance of reservoirs;
 
 
·
extensive engineering judgments; and
 
 
·
royalty and share oil policies in the PRC and foreign countries and regions where we have operations or assets.
 
Many of the factors, assumptions and variables involved in estimating reserves are beyond our control and may prove to be incorrect over time.  Consequently, the results of drilling, testing and production may require substantial upward or downward revisions in our initial reserves data.  For more information on our oil and gas reserves data, see “Item 4—Information on the Company—Business Overview—Exploration and Production—Oil and Natural Gas Reserves.”
 
14

 
Any failure to develop our proved undeveloped reserves and gain access to additional reserves could adversely affect our business and our financial position
 
Approximately 59.3% of our proved reserves were undeveloped as of December 31, 2007.  Our future success will depend on our ability to develop these reserves in a timely and cost-effective manner.  There are various risks in developing reserves, including construction, operational, geophysical, geological and regulatory risks.  Future drilling, exploration and acquisition activities may not be successful.  If our exploration and development activities or acquisition of properties containing proved reserves are unsuccessful, our total proved reserves will decline.
 
Our future prospects largely depend on our capital expenditure plans, which are subject to various risks
 
The oil and gas exploration and production business is capital intensive.  Our ability to maintain and increase our revenues, profit and cash flows depends upon continued capital spending.  Our capital expenditure plans are subject to a number of contingencies, some of which are beyond our control.  These variables include:
 
 
·
our ability to generate sufficient cash flows from operations to finance our capital expenditures, investments and other requirements;
 
 
·
the availability and terms of external financing;
 
 
·
changes in crude oil and natural gas prices, which may affect cash flows from operations and capital expenditure and investment plans;
 
 
·
the mix of exploration and development activities conducted on an independent basis and under production sharing contracts;
 
 
·
new investment opportunities that may be presented to us, including international investment opportunities and liquefied and other natural gas projects;
 
 
·
approvals required from foreign governments for certain capital expenditures and investments outside the PRC;
 
 
·
our ability to obtain sufficient foreign currency to finance our capital expenditures; and
 
 
·
economic, political and other conditions in the PRC and in foreign countries and regions where we have operations.
 
Therefore, our actual capital expenditures and investments in the future may differ significantly from our current planned amounts.  There can be no assurance that we will be able to execute our capital expenditure program on schedule or as planned.  If we are unable to obtain sufficient funding for our operations or development plans, our business, revenues, profit and cash flows could be adversely affected.  For additional information on our capital expenditure plans and financing requirements, see “Item 5—Operating and Financial Review and Prospects—Liquidity and Capital Resources.”
 
Any failure to implement our natural gas business strategy may adversely affect our business and financial position
 
As part of our business strategy and to meet increasing market demand in China, we continue to expand our natural gas business.  In addition to the risks that affect our business generally, this strategy involves a number of risks and uncertainties including the following:
 
 
·
we have limited experience in investing in liquefied natural gas facilities, gas transmission and distribution systems, and overseas upstream natural gas properties;
 
 
·
the natural gas transmission and supply infrastructure in China is underdeveloped and its development depends on a number of factors, many of which are beyond our control, such as funding, national and local government approvals and timely completion of construction;
 
15

 
 
·
the natural gas market in China is also underdeveloped and its development depends on the establishment of long-term natural gas supply contracts with natural gas utilities or large end-users, such as power and chemical plants.  The demand of these buyers for natural gas could be affected by a number of regulatory and market factors, such as regulation of coal prices, government power and utility policies, chemical commodity cycles, electricity pricing and demand, and environmental policies;
 
 
·
we do not have the same preferential rights with respect to overseas natural gas businesses that we enjoy with respect to our upstream natural gas business offshore China; and
 
 
·
we are evaluating the options to invest in CNOOC’s liquefied natural gas projects in China.  However, we have not decided whether to exercise these options.  The options are subject to various conditions, including the receipt of certain governmental approvals.
 
Due to the above factors or other reasons, we may fail to implement our natural gas strategy successfully.
 
CNOOC largely controls us and we regularly enter into related party transactions with CNOOC and its affiliates
 
CNOOC indirectly owned 64.41% of our shares as of May 30, 2008.  As a result, CNOOC is able to control the composition of the board of directors of our company (our “Board”), determine the timing and amount of our dividend payments and otherwise control us.  Therefore, CNOOC may cause us to enter into transactions, to take or fail to take other actions, or to make decisions that conflict with the best interests of our other shareholders. If CNOOC takes actions that favor its interests over ours, our results of operations and financial position may be adversely affected.
 
In addition, we regularly enter into transactions with CNOOC and its affiliates, such as China Oilfield Services Limited (“COSL”), and Offshore Oil Engineering Co., Ltd. (“CNOOC Engineering”).  For further details, see “Item 7—Major Shareholders and Related Party Transactions.”  Some of our transactions with CNOOC and its affiliates constitute connected transactions under the Hong Kong Stock Exchange Listing Rules.  However, these connected transactions are subject to review by the Hong Kong Stock Exchange and may also be subject to the prior approval of our independent shareholders.  If we do not obtain these approvals, we will not be allowed to effect these transactions and our business operations and financial condition could be adversely affected.
 
Under current PRC law, CNOOC has the exclusive right to enter into production sharing contracts with foreign oil and gas companies for petroleum exploration and production offshore China, and we are restricted from contracting directly with foreign enterprises for these purposes without CNOOC.  CNOOC has undertaken to us that it will transfer all of its rights and obligations under any new production sharing contracts to us, except those relating to its administrative functions. The interests of CNOOC in entering into production sharing contracts with international oil and gas companies may differ from our interests, especially with respect to the criteria for determining whether, and on what terms, to enter into production sharing contracts.  Our future business development may be adversely affected if CNOOC does not enter into new production sharing contracts on terms that are acceptable to us.
 
Our business performance relies heavily on our sales to large domestic customers and a substantial drop in such sales could have a material adverse effect on our results of operations
 
We sell a significant proportion of our production to CNOOC-affiliated companies and China Petroleum & Chemical Corporation (“Sinopec”).  For the years ended December 31, 2005, 2006 and 2007, net sales to CNOOC-affiliated companies accounted for 38.3%, 39.9% and 35.0%, respectively, of our total operating revenues, and sales to Sinopec accounted for 22.5%, 21.6% and 24.0%, respectively, of our total operating revenues. CNOOC has a controlling interest in us.  However, our transactions with CNOOC-affiliated companies are on normal commercial terms and CNOOC does not guarantee our sales volume or profit margin. Sinopec has its own oil and gas fields and has the right to import crude oil directly from the international market.  We do not have any long-term crude oil sales contracts with CNOOC and its affiliates or Sinopec.  Our business, results of operations and financial condition would be adversely affected if either CNOOC-affiliated companies or Sinopec significantly reduced their crude oil purchases from us and we could not find other ready buyers in the international market to purchase our crude oil at comparable prices and in comparable volumes.
 
16

 
The PRC petroleum and natural gas industries are very competitive
 
We compete in the PRC and international markets for customers, capital financing and business opportunities, including desirable oil and gas prospects.  The performance of our competitors may also affect the international market price for comparable crude oil, which in turn would likely affect the price of our crude oil.  Our principal competitors in the PRC market are PetroChina and Sinopec.  For further details, see “Item 4—Information on the Company—Business Overview—Competition.”
 
We are the dominant player in the oil and gas industry offshore China.  Currently, we, through CNOOC, are the only company permitted to engage in oil and gas exploration offshore China in cooperation with foreign oil and gas companies.  Any change to PRC law that allows new entrants to conduct oil and gas exploration activities offshore China in cooperation with international oil and gas companies could increase the competition for new oil and gas properties offshore China.
 
CNOOC has undertaken to us that so long as it retains a controlling interest in us and our securities are listed on the Hong Kong Stock Exchange, the New York Stock Exchange or other securities trading systems in other parts of the world, we will have the exclusive right to exercise CNOOC’s rights to engage in offshore oil and gas exploration, development, production and sales in the PRC and that it will not compete with us in such business.  However, CNOOC’s controlling interest in us may not continue in the future and CNOOC’s undertaking may be subject to interpretative challenges.  See “Item 4—Information on the Company—Organizational Structure” and “Item 7—Major Shareholders and Related Party Transactions.”
 
Exploration, development and production risks and natural disasters may affect our operations and could result in losses that are not covered by insurance
 
Our petroleum exploration, development and production operations are subject to various risks, including pipeline ruptures and spills, fires, explosions, encountering formations with abnormal pressures, blowouts, cratering and natural disasters.  Any of these risks could result in loss of hydrocarbons, environmental pollution and other damage to our properties and the properties of operators under production sharing contracts.  The costs of drilling, completing and operating wells also are uncertain and are subject to numerous factors beyond our control, including:
 
 
·
weather conditions;
 
 
·
natural disasters;
 
 
·
availability of equipment and services;
 
 
·
equipment shortages and delays; and
 
 
·
lack of adequate transportation facilities.
 
We maintain insurance coverage against some, but not all, potential losses.  We do not maintain business interruption insurance for all of our oil and gas fields.  We may suffer material losses resulting from uninsurable or uninsured risks or insufficient insurance coverage.  For further information on insurance coverage, see “Item 4—Information on the Company—Business Overview—Operating Hazards and Uninsured Risks.”
 
17

 
We are exposed to operating risks in some foreign countries and regions in which we have operations
 
We currently have operations and assets in various foreign countries and regions, including Indonesia, Australia and Nigeria, and may expand our operations into other countries to further enhance our reserve base and diversify our geographic risk profile.  See “Item 4—Information on the Company—Business Overview—Overseas Activity.”  These interests are subject to operating risks in their respective regions, including economic and political risks.
 
Our non-PRC interests are subject to the laws and regulations of these non-PRC jurisdictions respectively, including those relating to the development, production, marketing, pricing, transportation and storage of crude oil and natural gas, taxation and environmental and safety matters.  In addition, our overseas operations generally are subject to fiscal arrangements with our partners.  As we expand to different countries, we may become exposed to various operating risks in each of these jurisdictions.  Our non-PRC interests may be adversely affected by changes in governmental policies or social instability or other political, economic or diplomatic developments in or affecting these foreign nations which are not within our control, including, among other things, a change in crude oil or natural gas pricing policy, the risks of war and terrorism, expropriation, nationalization, renegotiation or nullification of existing concessions and contracts, taxation policies, foreign exchange and repatriation restrictions, changing political conditions, foreign exchange rate fluctuations and currency controls.
 
Some foreign countries and regions in which we have operations or may have operations in the future may not have diplomatic or trade relations with other countries and may be subject to trade or economic sanctions imposed by such other countries
 
While the foreign countries and regions in which we have operations or may have operations in the future may maintain an amicable relationship with China, some of them may not have diplomatic or trade relations with other countries and may be subject to trade or economic sanctions imposed from time to time by such other countries.  See “Item 4—Information on the Company—Business Overview—Overseas Activity—Asia—Myanmar.”  We will endeavor to limit our investment and scale of operations in these foreign jurisdictions to minimize our exposure, but we cannot assure that the operations and assets that we currently have or in the future may have in foreign countries and regions will not be affected by trade or economic sanctions that may be imposed by other countries due to their deteriorated relations with each other.  Our business and results of operations may be adversely affected if such sanctions are imposed and result in interruption of our overseas operations or non-accessibility of our overseas assets for a significant period of time.
 
Our controlling shareholder, CNOOC, or its affiliates may enter into activities in certain countries that are the subject of U.S. sanctions, which could result in negative media and investor attention.
 
CNOOC owns 64.41% of our outstanding shares, and is therefore our controlling shareholder.  CNOOC or its affiliates may from time to time engage in activities in countries that are the subject of U.S. economic sanctions.
 
We cannot predict the interpretation or implementation of U.S. government policy under the Iran Sanctions Act or other relevant measures with respect to any current or future activities by CNOOC or its affiliates in Iran or other countries that are the subject of U.S. sanctions.  It is possible that the United States could subject CNOOC to sanctions due to these activities.
 
It is possible that as a result of activities by CNOOC or its affiliates in these countries, we may be subject to negative media or investor attention, which may distract management, consume internal resources and affect investors’ perception of our company.  Nonetheless, if such events were to occur, we do not believe that enforcement of U.S. sanctions (including the imposition of the maximum sanctions under the current law and regulations on CNOOC) would have a material adverse effect on our results of operations or financial condition.
 
18

 
We may be penalized if we fail to comply with existing or future environmental laws and regulations
 
Our business is subject to environmental protection laws and regulations in the PRC, as well as other jurisdictions, which, among other things:
 
 
·
impose fees for the discharge of waste substances;
 
 
·
require the payment of fines and damages for serious environmental pollution; and
 
 
·
provide that the government may, at its discretion, close or suspend any facility which fails to comply with orders requiring it to cease or cure operations causing environmental damage.
 
We believe that all of our facilities and operations are in material compliance with the requirements of the relevant environmental protection laws and regulations. However, amendment of existing laws or regulations may impose additional or more stringent requirements.  In addition, our compliance with such laws or regulations may require us to incur significant capital expenditures or other obligations or liabilities, which could create a substantial financial burden on us.  For a further discussion of the relevant environmental regulations, particularly those in the PRC, see “Item 4—Information on the Company—Business Overview—Regulatory Framework—Environmental Regulation.”
 
Risks relating to the PRC petroleum industry
 
A change in PRC petroleum industry regulations could have an adverse effect on our operations
 
The PRC government exercises control over the PRC petroleum industry, including with respect to licensing, exploration, production, distribution, pricing, taxation, imports and exports and allocation of various resources.  We have benefited from various favorable PRC government policies, laws and regulations that have been enacted to encourage the development of the offshore petroleum industry.  See “Item 4—Information on the Company—Regulatory Framework—Special Policies Applicable to the Offshore Petroleum Industry in China” and “Item 4—Information on the Company—Business Overview—PRC Fiscal Regimes for Offshore Crude Oil and Natural Gas Activities.”  We cannot assure that the legal and fiscal regimes affecting our businesses will remain substantially unchanged or that we will continue to benefit from favorable PRC government policies.
 
Changes to the tax regime affecting the petroleum industry that have been recently implemented or are currently under consideration could increase our tax burden.  In March 2006, the PRC government imposed a special oil gain levy on revenues generated from sales of domestically produced crude oil when the realized price exceeds US$40 per barrel, which significantly increased our expenses.  In addition, the PRC government imposed an export tariff of 5% on crude oil in November 2006.  The PRC government has also announced that it plans to reform the current resource taxation system, which could increase our tax burden.
 
In addition, existing PRC regulations require us to apply for and obtain various PRC government licenses and other approvals, including in some cases approvals for amendments and extensions of existing licenses and approvals, to conduct exploration and development activities offshore China.  If we are unable to obtain any necessary approvals, our reserves and production would be adversely affected.  See “Item 4—Information on the Company—Regulatory Framework.”
 
Risks relating to the PRC
 
PRC economic and political conditions may adversely affect our operations
 
Most of our businesses, assets and operations are located in the PRC.  The economic system of the PRC differs from the economies of most developed countries in many respects, including government investment, control of capital investment and control of foreign exchange.
 
19

 
The economy of the PRC has been undergoing a transformation from a planned economy to a market-oriented economy.  In recent years the PRC government has implemented economic reform measures emphasizing decentralization, utilization of market forces in the development of the PRC economy and a higher level of management autonomy.  These economic reform measures have and will continue to subject our businesses to some uncertainty.  In the future, our operating results could be adversely affected by changes to the laws and regulations that govern our industry and changes in the PRC political and economic systems.
 
The PRC government has implemented various policies from time to time to restrain the rate of such economic growth, control inflation and otherwise regulate economic expansion. Certain measures taken by the PRC government, such as placing additional controls on prices of petroleum and petroleum products, could restrict our business operations and adversely affect our financial position.
 
Government control of currency conversion and future movements in exchange rates may adversely affect our operations and financial condition
 
A portion of our Renminbi revenue may need to be converted into other currencies by our wholly owned principal operating subsidiary in the PRC, CNOOC China Limited, to meet our foreign currency obligations.  We have substantial requirements for foreign currency, including:
 
 
·
debt service on foreign currency denominated debt;
 
 
·
overseas acquisitions of oil and gas properties;
 
 
·
purchases of imported equipment; and
 
 
·
payment of dividends declared in respect of shares held by international investors.
 
CNOOC China Limited may undertake current account foreign exchange transactions without prior approval from the State Administration for Foreign Exchange.  It has access to current account foreign exchange so long as it can produce commercial documents evidencing such transactions and provided that they are processed through certain banks in China.  Foreign exchange transactions under the capital account, including principal payments with respect to foreign currency denominated obligations, are subject to the approval requirements of the State Administration for Foreign Exchange.
 
The value of the Renminbi against the U.S. dollar and other currencies may fluctuate and is affected by, among other things, changes in China’s political and economic conditions. On July 21, 2005, China reformed its foreign exchange regime by moving into a managed floating exchange rate regime based on market supply and demand with reference to a basket of currencies. From that day to May 30, 2008, the Renminbi appreciated approximately 19.1% against the U.S. dollar.

The appreciation of the Renminbi against the U.S. dollar may cause a decrease in our oil sales, since the benchmark oil prices are usually in U.S. dollars. However, the appreciation of the Renminbi against the U.S. dollar may also decrease our costs for imported equipment and materials, most of which are denominated in U.S. dollars, as well as our debt repayment burden, since approximately 96% of our debt is denominated in U.S. dollars. For further information on foreign exchange risks, foreign exchange rates and hedging activities,  see “Item 3—Key Information—Selected Financial Data” and “Item 11—Qualitative and Quantitative Disclosure about Market Risk.”
 
Certain legal restrictions on dividend distribution may have a material adverse effect on our cash flows
 
We are a holding company.  Our exploration, development, production and sales businesses are owned and conducted through various wholly owned subsidiaries, including CNOOC China Limited, our wholly foreign-owned enterprise in the PRC.  Accordingly, our future cash flows will consist principally of dividends from our subsidiaries.  Our PRC subsidiary’s ability to pay dividends to us is subject to PRC regulations, including a restriction that companies may pay dividends only out of profit determined in accordance with PRC accounting standards and regulations.  In addition, under PRC laws, CNOOC China Limited is required to allocate at least 10% of its net profit to a reserve fund until the balance of the fund has reached 50% of its registered capital.  The balance of the reserve fund of CNOOC China Limited reached 50% of its registered capital in 2007 and CNOOC China Limited will be required to make further allocations only if its registered capital is increased..  Such reserve is not distributable as cash dividends.  Therefore, there is a risk that we may not be able to maintain sufficient cash flows due to these restrictions on dividend distribution.
 
20

 
The interpretation and enforcement of PRC laws and regulations is subject to some uncertainty
 
The PRC legal system is based on statutory law.  Under this system, prior court decisions may be referred to but are not binding.  Since 1979, the PRC government has been developing a comprehensive system of commercial laws and considerable progress has been made in the promulgation of laws and regulations dealing with economic matters, such as corporate organization and governance, foreign investments, commerce, taxation and trade.  Because these laws, regulations and legal requirements are relatively new, and because of the limited volume of published cases and judicial interpretations and the non-binding nature of prior court decisions, the interpretation and enforcement of these laws, regulations and legal requirements involve some uncertainty.
 
Risks relating to our ADSs and shares
 
Additional shares or ADSs eligible for public sale could adversely affect the price of our shares or ADSs
 
Sales, or the real or perceived possibility of sales, of a significant number of additional shares in the public market could adversely affect prevailing market prices for our shares and ADSs.  As of May 30, 2008, CNOOC, through its wholly owned subsidiaries, CNOOC (BVI) Limited and Overseas Oil & Gas Corporation Ltd., held approximately 64.41% of our shares and the rest of our shares were held by public investors, including institutional investors.  We cannot predict the effect, if any, that sales of our shares, including sales of large positions held by institutional and corporate investors, or the availability of our shares for future sale, will have on the market price of our shares or ADSs.

ITEM 4. INFORMATION ON THE COMPANY
 
 
Our legal and commercial name is CNOOC Limited.  We were incorporated with limited liability on August 20, 1999 in Hong Kong under the Hong Kong Companies Ordinance.  Our business registration number in Hong Kong is 685974.  Under the third section of our memorandum of association, we may do anything which we are permitted to do by any enactment or rule of law.  Our head office is located at 65th Floor, Bank of China Tower, One Garden Road, Central, Hong Kong, and our telephone number is 852-2213-2500.
 
The PRC government established CNOOC, our controlling shareholder, as the state-owned offshore petroleum company of China in 1982 under the Regulation of the People’s Republic of China on the Exploitation of Offshore Petroleum Resources in Cooperation with Foreign Enterprises, whereby CNOOC assumed overall responsibility for the administration and development of PRC offshore petroleum operations with foreign oil and gas companies.  Prior to March 2003, CNOOC was regulated and supervised by the State Economic and Trade Commission.  Since March 2003, the PRC government has undergone substantial reform.  The National Development and Reform Commission has succeeded the State Economic and Trade Commission as the primary coordinator for the petroleum industry.
 
Prior to CNOOC’s internal business reorganization in 1999, CNOOC and its various affiliates performed both commercial and administrative functions relating to petroleum exploration and development offshore China, including:
 
 
·
exercising the exclusive right to cooperate with foreign partners in offshore petroleum exploration, development, production and sales activities, and taking participating interests in production sharing contracts;
 
21

 
 
·
organizing international bidding for offshore petroleum exploitation;
 
 
·
conducting independent exploration, development, production and sales activities in independently operated oil and gas fields offshore China;
 
 
·
awarding contracts to and signing bilateral contracts with foreign partners for offshore petroleum exploitation;
 
 
·
reviewing and confirming appraisal reports and overall development plans required under production sharing contracts; and
 
 
·
obtaining from the PRC government all approvals, permits, licenses, consents and special policies necessary under production sharing contracts.
 
Reorganization
 
Pursuant to CNOOC’s internal business reorganization in 1999, CNOOC transferred all of its then current operational and commercial interests in its offshore petroleum business, including the related assets and liabilities, to us. CNOOC also transferred 917 employees to us to facilitate the transfer of the oil and natural gas businesses previously operated by CNOOC. As a result, we and our subsidiaries are the only vehicle through which CNOOC engages in petroleum exploration, development, production and sales activities both within and outside China.
 
CNOOC retained its commercial interests in operations and projects not related to oil and gas exploration and production, as well as all of its administrative functions, which it performed prior to the reorganization, including:
 
 
·
organizing international bidding for offshore petroleum exploitation;
 
 
·
awarding contracts to and signing bilateral contracts with foreign partners for offshore petroleum exploitation;
 
 
·
approving any extension of the period for the completion of the appraisal work on petroleum discovery under the production sharing contracts; and
 
 
·
submitting the overall development plans, reports of the oil and gas fields and the environmental impact statements related to the production sharing contracts to the PRC governmental authorities.
 
Undertakings
 
CNOOC has undertaken to us that:
 
 
·
we will enjoy the exclusive right to exercise all of CNOOC’s commercial and operational rights under the PRC laws and regulations relating to the exploration, development, production and sales of oil and natural gas offshore China;
 
 
·
it will transfer to us all of CNOOC’s rights and obligations under any new production sharing contracts and geophysical exploration operations, except those relating to CNOOC’s administrative functions;
 
 
·
it will not engage or be interested, directly or indirectly, in oil and natural gas exploration, development, production and sales in or outside the PRC;
 
 
·
we will be able to participate jointly with CNOOC in negotiating new production sharing contracts and to set out our views to CNOOC on the proposed terms of new production sharing contracts;
 
22

 
 
·
we will have unlimited and unrestricted access to all data, records, samples and other original data owned by CNOOC relating to oil and natural gas resources;
 
 
·
we will have an option to make investment in liquefied natural gas projects in which CNOOC invested or proposed to invest, and CNOOC will at its own expense help us to procure all necessary government approvals needed for our participation in these projects; and
 
 
·
we will have an option to participate in other businesses related to natural gas in which CNOOC invested or proposed to invest, and CNOOC will procure all necessary government approvals needed for our participation in such business.
 
The undertakings from CNOOC will cease to have any effect:
 
 
·
if we become a wholly owned subsidiary of CNOOC;
 
 
·
if our securities cease to be listed on any stock exchange or automated trading system; or
 
 
·
12 months after CNOOC or any other PRC government-controlled entity ceases to be our controlling shareholder.
 
B.
 
Overview
 
We are an oil and gas company engaged in the exploration, development and production of crude oil and natural gas primarily offshore China.  We are the dominant producer of crude oil and natural gas offshore China and, through CNOOC, are the only company permitted to conduct exploration and production activities with foreign oil and gas companies offshore China.  As of December 31, 2007, we had estimated net proved reserves of 2,601.2 million BOE, comprised of 1,564.1 million barrels of crude oil and condensate and 6,222.8 billion cubic feet of natural gas.  For 2007, our net production averaged 371,827 barrels per day of crude oil, condensate and natural gas liquids and 559.6 million cubic feet per day of natural gas, which together totaled 469,407 BOE per day.  Unless otherwise noted, all operating data presented in this annual report, including reserve and production information, includes our interest in the oil and gas field held by an unconsolidated investee in which we hold a 30% equity interest.  For more information on our reserves and related information, see “Supplementary Information on Oil and Gas Producing Activities” in our consolidated financial statements included elsewhere in this annual report, in which we separately disclose reserve and related information for this unconsolidated investee in accordance with U.S. Statement of Financial Accounting Standards No. 69, “Disclosures about Oil and Gas Producing Activities.”
 
Our net proved reserves increased from 2,528.5 million BOE as of December 31, 2006 to 2,601.2 million BOE as of December 31, 2007, representing an increase of 2.9%.  Based on net proved reserves, we are one of the largest independent oil and gas exploration and production companies in the world.  In the petroleum industry, an “independent” company owns oil and gas reserves independently of other downstream assets, such as refining and marketing assets, whereas an integrated company owns downstream assets in addition to oil and gas reserves.
 
We conduct exploration, development, production and sales activities through both independent operations and production sharing contracts with foreign partners.  We have added to our reserves in recent years primarily through our independent operations.  As of December 31, 2007, independent properties accounted for 62.0% of our total net proved reserves and independent net proved undeveloped reserves accounted for 64.8% of our total net proved undeveloped reserves.  For the year ended December 31, 2007, production from our independent properties accounted for 46.8% of our total net production.

Our controlling shareholder, CNOOC, has the exclusive right to enter into contracts with international oil and gas companies to conduct exploration and production activities offshore China.  Under these production sharing contracts, we have the sole right to acquire, at no cost, participating interests in any successful discovery offshore China made by our foreign partners.  Our foreign partners can recover their exploration costs under the production sharing contracts only if a commercially viable discovery is made.  As of December 31, 2007, we had 27 foreign partners under our existing production sharing contracts offshore China, all of which are international oil and gas companies, including BG International Ltd., BP China Exploration & Production Company, Burlington Resources China LLC, ChevronTexaco China Energy Company, ConocoPhillips China Inc., Devon Energy China Ltd., ENI China B.V., Horizon Oil Ltd., Husky Oil China Ltd., Kerr-McGee China Petroleum Ltd., Newfield China LDC., Roc Oil (China) Company, Shell China Exploration and Production Co., Ltd. and Texas American Resources-Asia Limited.  As of December 31, 2007, we were a party to 40 production sharing contracts offshore China.  We are currently the operator or joint operator of some of the properties developed under our production sharing contracts.
 
Natural gas is becoming an increasingly important part of our business strategy because of rapidly growing domestic demand.  In view of increasing demand for natural gas, we have continued to explore for natual gas and develop our natural gas properties. We have also made strategic investments in liquefied natural gas related upstream projects outside the PRC, and may continue to do so in the future.  We have acquired interests in gas reserves located in Tangguh, Indonesia and the North West Shelf, Australia.  In addition, CNOOC, our controlling shareholder, has granted us an option to invest in liquefied natural gas projects or other natural gas related business in which CNOOC invested or proposed to invest.  The terms of this option require us, if we exercise the option, to reimburse CNOOC for any contribution CNOOC has made with respect to the project together with interest calculated at the prevailing market rate.  CNOOC’s major liquefied natural gas projects in the PRC, which it has entered into with various partners, include LNG terminals under production or development in Guangdong, Fujian, Zhejiang and Shanghai.
 
Competitive Strengths
 
We believe that our historical success and future prospects are directly related to a combination of our strengths, including the following:
 
 
·
large proved reserve base with significant exploitation opportunities;
 
 
·
sizable operating areas with demonstrated exploration potential;
 
 
·
successful independent exploration and development record;
 
 
·
competitive cost structure;
 
 
·
reduced risks and access to capital and technology through production sharing contracts;
 
 
·
strategic position in China’s growing natural gas markets; and
 
 
·
experienced management team.
 
Large proved reserve base with significant exploitation opportunities
 
Based on net proved reserves as of December 31, 2007 and net production for the year ended December 31, 2007, we had a reserve-to-production ratio of 15.2 years.  As of December 31, 2007, approximately 59.3% of our net proved reserves were classified as net proved undeveloped.  Our large proved reserve base gives us the opportunity to achieve substantial production growth.
 
Sizable operating area with demonstrated exploration potential
 
Since CNOOC’s inception in 1982 to the end of 2007, we and foreign partners have together drilled a total of 929 exploration wells in China’s sizable offshore exploration area, including 589 wildcat wells with a success rate of approximately 35%.  For the year ended December 31, 2007, we and foreign partners made 11 discoveries and one discovery, respectively, offshore China.
 
24

 
Successful independent exploration and development record.
 
From the inception of CNOOC in 1982 to December 31, 2007, we achieved a success rate of approximately 42% on our 290 offshore China independent wildcat wells.  As of December 31, 2007, independent properties accounted for 62.0% of our total net proved reserves and independent net proved undeveloped reserves accounted for 64.8% of our total net proved undeveloped reserves.  In 2007, we, acting as operator, completed 5 of our major development projects.
 
Competitive cost structure
 
For the year ended December 31, 2007, our total offshore China lifting costs, also known as production costs, were US$8.60 per BOE.  Total lifting costs for independent operations offshore China were US$8.39 per BOE during the same period.  Lifting costs consist of operating expenses and production taxes.  We have kept our offshore China lifting costs low through various measures, including more efficient use of existing offshore facilities, the linking of employee bonuses to cost reduction and the adoption of new technology in our operations.  We believe that such cost structure allows us to compete effectively even in a low crude oil price environment.
 
Reduced risks and access to capital and technology through production sharing contracts
 
Production sharing contracts help us minimize our offshore China finding costs, exploration risks and capital requirements because our foreign partners are responsible for all costs associated with exploration.  Our foreign partners recover their exploration costs only if a commercially viable discovery is made.
 
Strategic position in China’s growing natural gas markets
 
The proximity of our natural gas reserves to the major demand areas in the coastal regions of China provides us with a competitive advantage over other natural gas suppliers in China, whose natural gas reserves are located primarily in northwest and southwest China.  We have natural gas fields near many of China’s rapidly growing coastal areas, including Hong Kong, Shanghai and Guangzhou.  We have also acquired interests in gas reserves located in Tangguh, Indonesia and the North West Shelf, Australia.  In addition, CNOOC has granted us an option to invest in liquefied natural gas projects or other natural gas related businesses in the PRC in which CNOOC invested or proposed to invest.  For further information, see “Item 4—Information on the Company—Business Overview—Overview.”
 
Experienced management team
 
Our senior management team has extensive experience in the oil and gas industry, and most of our executives have been with the CNOOC group since its inception in 1982.  We evolved from a company heavily reliant on production sharing contracts with foreign partners to a company with a balance of both independent and production sharing contract operations.  Our management team and staff have had the opportunity to work closely with foreign partners both within and outside China.  We have implemented international management practices, including incentive compensation arrangements such as share option schemes.  See “Item 6—Directors, Senior Management and Employees—Share Ownership.”
 
Business Strategy
 
We intend to continue expanding our oil and gas exploration and production activities and, where appropriate, to continue making strategic investments in natural gas businesses.  While our expansion strategy will continue to focus primarily on offshore China, we may also consider overseas acquisition opportunities that may be presented to us.  The principal components of our strategy are as follows:
 
 
·
increase production primarily through the development of our net proved undeveloped reserves;
 
 
·
add to our reserves through independent exploration and production sharing contracts;
 
25

 
 
·
capitalize on the growing demand for natural gas in China;
 
 
·
selectively pursue acquisitions to ensure long-term production growth, geographical reserves risk diversification, and to further our natural gas strategy;
 
 
·
maintain operational efficiency and low production costs; and
 
 
·
maintain financial flexibility through prudent financial practices.
 
Increase production primarily through the development of our net proved undeveloped reserves
 
As of December 31, 2007, approximately 59.3% of our proved reserves were classified as net proved undeveloped, which gives us the opportunity to achieve substantial production growth even without additional reserve discoveries, assuming that we will be able to develop these reserves more quickly than we deplete our currently producing reserves.  We are currently undertaking a number of large development projects, which are primarily located in the Bohai Bay and the Western South China Sea offshore China and in Nigeria and Indonesia.  We plan to spend approximately US$4,149 million to develop our net proved undeveloped reserves in 2008.
 
Add to our reserves through independent exploration and production sharing contracts
 
We plan to concentrate our independent exploration efforts in existing operating areas.  We plan to spend approximately US$1,042 million in 2008 on exploration activities.  We plan to increase independent exploration efforts while continuing to enter into production sharing contracts with foreign partners to lower capital requirements and exploration risks.  In 2008, we plan to drill approximately 86 exploration wells, and independently acquire approximately 33,350 kilometers and 12,460 square kilometers of 2D seismic data and 3D seismic data, respectively.  Our foreign partners under existing production sharing contracts plan to drill approximately 40 exploration wells, and acquire approximately 5,200 kilometers and 10,638 square kilometers of 2D seismic data and 3D seismic data, respectively, in 2008.
 
Capitalize on the growing demand for natural gas in China
 
We plan to capitalize on the growth potential of the PRC natural gas market through the following initiatives:
 
 
·
continue to explore and develop natural gas fields;
 
 
·
evaluate whether to exercise the options to invest in CNOOC’s liquefied natural gas projects in China; and
 
 
·
evaluate investment opportunities in related natural gas businesses that will help develop markets for our natural gas production.
 
To the extent we invest in businesses and geographic areas where we have limited experience and expertise, we plan to structure our investments as alliances or partnerships with parties possessing the relevant experience and expertise.
 
Selectively pursue acquisitions to ensure long-term production growth and geographical reserves risk diversification, and to further our natural gas strategy
 
We plan to make selective acquisitions that will meet one or more of our strategic objectives of enhancing our production profile, diversifying our reserve base and geographic risk profile and furthering our natural gas strategy.  We evaluate acquisition opportunities based on our expected economic return criteria. Since 2002, we have made a number of acquisitions overseas.  We currently have operations and assets in various foreign countries and regions, including Indonesia, Australia and Nigeria.  See “Item 4—Information on the Company—Business Overview—Overseas Activity.”
 
26

 
Maintain operational efficiency and low production costs
 
We will continue to maintain our low cost structure and operational efficiency through the following initiatives:
 
 
·
Apply up-to-date drilling, production and offshore engineering technology to our operations through our oilfield service providers;
 
 
·
Proactively manage service contracts and cooperate with our oilfield service providers to improve exploration efficiency and reduce exploration costs; and
 
 
·
Maintain high production volume levels on an individual well basis and increase the productivity of producing wells.
 
Maintain financial flexibility through prudent financial practices
 
Currently, we have a strong financial profile with a low leverage ratio.  We intend to maintain our financial strength by managing key measures such as capital expenditures, cash flows and fixed charge coverage.  We intend to actively manage our accounts receivable and inventory positions to enhance liquidity and improve profitability.  We will continue to monitor our foreign currency denominated debt and to minimize our exposure to foreign exchange rate fluctuations.

Exploration and Production
 
Summary

We currently conduct exploration, development and production activities primarily in four areas offshore China:
 
 
·
the Bohai Bay;
 
 
·
the Western South China Sea;
 
 
·
the Eastern South China Sea; and
 
 
·
the East China Sea.
 
 
29

 
The following chart sets forth the aggregate area in square kilometers of our major exploration areas as of December 31, 2007.

 
In addition, we hold several equity interests in oil and gas properties in foreign countries and regions, including Indonesia, Australia and Nigeria.  See “Item 4—Information on the Company—Business Overview—Overseas Activity.”
 
As of December 31, 2007, we had estimated net proved reserves of 2,601.2 million BOE, comprised of 1,564.1 million barrels of crude oil and condensate and 6,222.8 billion cubic feet of natural gas.  As of December 31, 2007, we had interests in 58 producing properties and 51 properties under development offshore China.  In 2007, four projects offshore China and one overseas project commenced production.  For 2007, net production averaged 371,827 barrels per day of crude oil, condensate and natural gas liquids and 559.6 million cubic feet per day of natural gas, which together totaled 469,407 BOE per day, representing a 2.6% increase over the annual average daily production for 2006.
 
We conduct our exploration, development and production activities independently as well as through production sharing contracts with foreign partners.  Production sharing contracts contain provisions regarding the exploration, development, production and operation of an oil and gas field and the formula through which foreign partners may recover exploration, development and production costs and share in the production after the successful development of petroleum reserves. In 2007, our controlling shareholder, CNOOC, signed four production sharing contracts offshore China with foreign partners, most of which relate to area in the South China Sea. See “Item 4—Information on the Company—Business Overview—Fiscal Regimes—Offshore China” for a detailed discussion of these arrangements.
 
From time to time, we also conduct exploration efforts through geophysical survey agreements with foreign companies.  These geophysical survey agreements allow international oil and gas companies to make geophysical surveys and conduct geophysical studies before deciding whether to negotiate a production sharing contract with CNOOC.  If a foreign partner decides to enter into a production sharing contract with CNOOC, the costs and expenses that the foreign partner incurs in conducting geophysical exploration may be recovered during the production period by the foreign partner, subject to our confirmation.  Currently, we are not a party to any geophysical survey agreements.
 
We have access to 932,484 kilometers of 2D seismic data and 60,611 square kilometers of 3D seismic data.  From the beginning of CNOOC’s operations in 1982 to December 31, 2007, a total of 929 exploration wells have been drilled, including 589 wildcat wells, with a success rate of approximately 35%.  During this period we achieved a success rate of approximately 42% on 290 independent exploration wildcat wells, while our foreign partners achieved a success rate of approximately 28% on their 299 exploration wildcat wells.

Oil and Natural Gas Reserves
 
We have a large base of net proved undeveloped reserves as a result of our exploration successes.  As of December 31, 2007, approximately 59.3% of our net proved reserves were classified as net proved undeveloped.
 
As reflected in the reconciliation in “Supplementary Information on Oil and Gas Producing Activities” on page S-1 of this annual report, the primary sources of our reserve additions in 2007 were discoveries and extensions in the Bohai Bay and the Eastern South China Sea.  For more information on these activities see “Item 4—Information on the Company—Business Overview—Principal Oil and Gas Regions Offshore China—Bohai Bay” and “Item 4—Information on the Company—Business Overview—Principal Oil and Gas Regions Offshore China—Eastern South China Sea.”  61.7% of our reserve additions in 2007 were proved undeveloped reserves, which generally take more time and funding to bring to production than do proved developed reserves.  A number of risks, including factors outside our control, can impact the extent to which future reserve additions will come from a given source and the time and costs involved in bringing reserves additions to production.  For information on risks relating to our reserves, see “Item 3—Key Information—Risk Factors—Risks relating to our business.”
 
We explore and develop our reserves offshore China under exploration and production licenses granted by the PRC government.  The PRC government generally grants exploration licenses for individual blocks, while production licenses generally are granted for individual fields.  All of our proved reserves are under production licenses granted by the PRC government.
 
The following tables set forth net proved crude oil reserves, net proved natural gas reserves and total net proved reserves, as of the dates indicated, for our independent and production sharing contract operations in each of our operating areas.

Principal Oil and Gas Regions Offshore China
 
Bohai Bay
 
The Bohai Bay holds our largest net proved reserves and, for the year ended December 31, 2007, was our largest producing area for crude oil.  The Bohai Bay is located in the northeastern part of China, approximately 200 kilometers east of Beijing.  Our operating area contains oil and gas fields in shallow waters with typical depths ranging from 10 to 30 meters.  The crude oil produced is generally of heavy gravity ranging from 15 to 20 degrees API.  As of December 31, 2007, net proved reserves in this region were 951.3 million barrels of crude oil and condensate and 761.5 billion cubic feet of natural gas, totaling 1,078.2 million BOE and representing approximately 41.5% of our total net proved reserves.
 
The Bohai Bay has been a prolific area with significant oil discoveries in recent years and we expect it will continue to be one of our principal areas for exploration in the near future.  In 2007, we independently drilled in this area 12 wildcat wells, three of which were successful, and 24 appraisal wells, 15 of which were successful.  In 2007, our foreign partners drilled in this area four wildcat wells, one of which was successful, and one appraisal well, which was successful.  We and our foreign partners made three discoveries and one discovery, respectively, in this area in 2007.  During the year ended December 31, 2007, we independently acquired 3,554 square kilometers of 3D seismic data in the Bohai Bay.  We have an aggregate of approximately 181,664 kilometers and 15,560 square kilometers of independent 2D and 3D seismic data, respectively, in the Bohai Bay.  We also have access through our production sharing contract partners to approximately 66,903 kilometers and 9,561 square kilometers of additional 2D and 3D seismic data, respectively, in this area.  Our exploration capital expenditures for 2007 for the Bohai Bay were US$243 million.  We currently plan to drill 40 exploration wells in the Bohai Bay in 2008.
 
For 2007, net production in this region averaged 206,748 barrels per day of crude oil, condensate and natural gas liquids and 70.2 million cubic feet per day of natural gas, representing approximately 46.5% of our total daily net production.  Our development capital expenditures for the Bohai Bay for 2007 were US$1,240 million.

Western South China Sea
 
The Western South China Sea has been our most important natural gas producing area.  The Western South China Sea is located in the southern part of China southwest of Hong Kong.  Typical water depths of our operating area in this region range from 40 meters to 120 meters.  The crude oil produced is of medium to light gravity, ranging from 27 to 41 degrees API.  As of December 31, 2007, we had net proved reserves of 208.9 million barrels of crude oil and condensate and 2,539.2 billion cubic feet of natural gas in this region, totaling 632.1 million BOE and representing 24.3% of our total net proved reserves.
 
The Western South China Sea is one of our least explored areas but we expect it will become increasingly important as the markets for natural gas in the southern part of China develop. In 2007, we independently drilled in this area nine wildcat wells, five of which were successful, and five appraisal wells, all of which were successful.  We made five discoveries in this area in 2007.

During the year ended December 31, 2007, we independently acquired 5,893 kilometers of 2D seismic data and 252 square kilometers of 3D seismic data and our foreign partners acquired 6,681 kilometers of 2D seismic data and 1,059 square kilometers of 3D seismic data in the Western South China Sea.  We have an aggregate of approximately 199,126 kilometers and 10,241 square kilometers of independent 2D and 3D seismic data, respectively, in the Western South China Sea.  We also have access through our production sharing contract partners to approximately 115,304 kilometers and 5,715 square kilometers of additional 2D and 3D seismic data, respectively, in this area.  Our exploration capital expenditures for the Western South China Sea for 2007 were US$159 million.  We currently plan to drill 25 exploration wells in the Western South China Sea area in 2008.
 
For 2007, net production in this region averaged 34,163 barrels per day of crude oil, condensate and natural gas liquids and 237.3 million cubic feet per day of natural gas, representing approximately 16.1% of our total daily net production.  Our development capital expenditures for the Western South China Sea for 2007 were US$681 million.
 
Eastern South China Sea
 
The Eastern South China Sea is currently one of our most important oil producing areas in terms of its contribution to our total production and sales.  The Eastern South China Sea is located in the southern part of China, southeast of Hong Kong.  This area includes the important Pearl River Mouth Basin.  Typical water depths of our operating area in this region range from 100 meters to 300 meters.  The crude oil produced is of heavy to light gravity, ranging from 20 to 40 degrees API.  As of December 31, 2007, we had net proved reserves of 226.6 million barrels of crude oil and condensate and 779.4 billion cubic feet of natural gas in this region, totaling 356.5 million BOE and representing approximately 13.7% of our total net proved reserves.
 
In 2007, we independently drilled in this area six wildcat wells, three of which were successful, and two appraisal wells, neither of which was successful.  In 2007, our foreign partners drilled in this area one wildcat well, which was not successful.  We made three discoveries in this area in 2007.
 
During the year ended December 31, 2007, we independently acquired 3,246 kilometers of 2D seismic data and 187 square kilometers of 3D seismic data and our foreign partners acquired 3,684 kilometers of 2D seismic data and 3,667 square kilometers of 3D seismic data in the Eastern South China Sea area.  We have an aggregate of approximately 82,801 kilometers and 5,019 square kilometers of independent 2D seismic data and 3D seismic data, respectively, in the Eastern South China Sea.  We also have access through our production sharing contract partners to approximately 116,099 kilometers and 12,042 square kilometers of additional 2D and 3D seismic data, respectively, in this area.  Our exploration capital expenditures for the Eastern South China Sea for 2007 were US$95 million.  We currently plan to drill 15 exploration wells in the Eastern South China Sea in 2008.

We sell crude oil produced overseas through China Offshore Oil (Singapore) International Pte Ltd.
 
We submit production and sales plans with respect to crude oil produced offshore China to the National Development and Reform Commission each year.  Based on information provided by China’s three crude oil producers, PetroChina, Sinopec and us, the National Development and Reform Commission compiles an overall national plan to coordinate sales.  Our sales of crude oil to the international market also require us to obtain export licenses issued by the PRC Ministry of Commerce.  Historically, we have been able to obtain all required export licenses.
 
Pricing
 
We price our crude oil with reference to prices for crude oil of comparable quality in the international market, including a premium or discount mutually agreed upon by us and our customers according to market conditions at the time of the sale.  Prices are quoted in U.S. dollars, but domestic sales are billed and paid in Renminbi.  We currently market three types of crude oil produced offshore China: Light Crude, Medium Crude and Heavy Crude.  The table below sets forth the sales and marketing volumes, pricing benchmarks and average realized prices for each of these three types of crude oil for the periods indicated.

Markets and Customers
 
We sell most of our crude oil production in the PRC domestic market.  We also sell to customers outside the PRC, including South Korea, Japan, the United States and Australia,  as well as to crude oil traders in the spot market.  For the years ended December 31, 2005, 2006 and 2007, we sold approximately 70.9%, 75.8% and 90.1%, respectively, of our crude oil in the PRC, and exported approximately 29.1%, 24.2% and 9.9%, respectively.
 
Most of our crude oil production sales in the PRC domestic market are to refineries and petrochemical companies that are affiliates of Sinopec, PetroChina and CNOOC, our controlling shareholder.  Sales volume to Sinopec has been high historically because most of the PRC refineries and petrochemical companies were affiliates of Sinopec.  After the restructuring of the PRC petroleum industry in July 1998, some refineries and petrochemical companies were transferred to PetroChina from Sinopec.  For the years ended December 31, 2005, 2006 and 2007, sales to Sinopec were approximately 41.9%, 39.7% and 44.1%, respectively, and sales to PetroChina were approximately 5.0%, 9.1% and 14.6%, respectively, of our total crude oil sales in the PRC domestic market.  Together these two customers accounted for approximately 46.9%, 48.8% and 58.7%, respectively, of our total crude oil sales in the PRC domestic market.  For the same periods, sales to affiliates of CNOOC were approximately 48.0%, 48.8% and 38.0%, respectively, of our total crude oil sales in the PRC domestic market.  For further information about our sales to CNOOC-affiliated companies, please see note 27 to our consolidated financial statements included elsewhere in this annual report.

Sales Contracts
 
We sign sales contracts with our oil customers for each shipment.  Sales contracts are standard form contracts containing ordinary commercial terms such as quality, quantity, price, delivery and payment.  All sales are made on free-on-board terms.  Some of our customers are required to make payments within 30 days after the shipper takes possession of the crude oil cargo at our delivery points. Some of them are required to make prepayment or provide guarantee letters or letter of credit.  As of December 31, 2005, 2006 and 2007, most of our account receivables were aged within six months. During the years ended December 31, 2005, 2006 and 2007, the accounts receivable turnover were approximately 32.6 days, 28.8 days and 31.4 days, respectively.  Doubtful accounts provision during the years ended December 31, 2005, 2006 and 2007 were nil.
 
We price our crude oil in U.S. dollars.  PRC customers are billed and make actual payments in Renminbi based on the exchange rate prevailing at the bill of lading date, while overseas customers are billed and are required to make payments in U.S. dollars within 30 days of the bill of lading date.
 
Sales of Natural Gas from Offshore China
 
In 1989, the PRC government adopted a favorable royalty treatment, which provides a royalty exemption for natural gas production up to two billion cubic meters (70.6 billion cubic feet or 11.8 million BOE) per year as compared to a royalty exemption available for crude oil production of up to one million tons or approximately seven million BOE per year.  This treatment also includes lower royalty rates on incremental increases in natural gas production as compared with the royalty rates for crude oil production.
 
Since 1989, the PRC government has adopted the following requirements for royalty payments of up to 3% of the annual gross production of natural gas:
 
Annual gross production
   
Royalty rate
 
Less than 2 billion cubic meters 
     
 
2–3.5 billion cubic meters
     
1.0%
 
3.5–5 billion cubic meters
     
2.0%
 
Above 5 billion cubic meters
     
3.0%
 
 
We sell a large portion of our offshore China natural gas production to Hong Kong and Hainan Province.  In December 1992, we entered into a long-term gas supply contract with Castle Peak Power in Hong Kong under which it agreed to purchase from us approximately 102.4 billion cubic feet of natural gas per year on a take-or-pay basis until 2015.  Gas prices are quoted and paid in U.S. dollars. Castle Peak Power purchased approximately 38.5% of our total offshore China natural gas production for the year ended December 31, 2007.  We sold the remaining of our total offshore China natural gas production to mainland China customers, including but not limited to China BlueChemical Ltd., Hainan Yangpu Power, Shandong Yantai Zhongshi Gas and Hainan Refinery.
 
The price of gas sold to the PRC market is determined by negotiations between us and prospective buyers based on market conditions.  Contracts typically consist of a base price with provisions for periodic resets and adjustment formulas which depend on a basket of crude oil prices, inflation and various other factors.
 
Procurement of Services
 
We usually outsource work in connection with the acquisition and processing of seismic data, reservoir studies, well drilling services, well logging and perforating services and well control and completion service to independent third parties, or CNOOC and its affiliates.
 
In addition, we normally employ, on a contract basis, independent third parties for single point mooring (“SPM”) services and employ either independent third parties or CNOOC and/or its affiliates for floating production storage and offloading (“FPSO”) services, and other services.  We conduct a bidding process to determine who we employ to construct platforms, terminals and pipelines, to drill production wells and to install offshore production facilities.  Both independent third parties and CNOOC affiliates participate in the bidding process. We are closely involved in the design and management of services by contractors and exercise extensive control over their performance, including their costs, schedule, quality and HSE (health, safety, and environment) measures.

Competition
 
Domestic Competition
 
The petroleum industry is very competitive.  We compete in the PRC and in international markets for customers as well as capital to finance our exploration, development and production activities.  Our principal competitors in the PRC market are PetroChina and Sinopec.
 
We price our crude oil on the basis of comparable crude oil prices in the international market.  The majority of our customers for crude oil are refineries affiliated with Sinopec and PetroChina to which we have been selling crude oil, from time to time.  Based on our dealings with these refineries, we believe that we have established a stable business relationship with them.
 
We are the dominant player in the oil and gas industry offshore China and, through CNOOC, are the only company permitted to engage in oil and gas exploration and production offshore China in cooperation with foreign parties.  We may face increasing competition in the future from other petroleum companies in obtaining new PRC offshore oil and gas properties, or, as a result of changes in current PRC laws or regulations permitting an expansion of existing companies’ activities or new entrants into the industry.
 
As part of our business strategy, we intend to expand our natural gas business to meet rapidly increasing domestic demand.  Our competitors in the PRC natural gas market are PetroChina and, to a lesser extent, Sinopec.  Our principal competitor, PetroChina, is the largest supplier of natural gas in China in terms of volume of natural gas supplied.  PetroChina’s natural gas business benefits from strong market positions in Beijing, Tianjin, Hebei Province and northern China.  We intend to develop related natural gas businesses in China’s coastal provinces, where we may face competition from PetroChina and, to a lesser extent, Sinopec.  We believe that our extensive natural gas resources base, the proximity of these resources to the markets in China and our experienced management team will enable us to compete effectively in the domestic natural gas market.
 
Foreign Competition and the World Trade Organization
 
Imports of crude oil are subject to import licenses, handling fees and other restrictions.  The PRC government also restricts the availability of foreign exchange with which the imports must be purchased.  The combination of licenses and restrictions on foreign exchange has, to some extent, limited the competition from imported crude oil.
 
In line with the general progress of its economic reform programs, the PRC government has agreed to reduce import barriers as part of its World Trade Organization commitments.  As a result of China joining the World Trade Organization as a full member on December 11, 2001, it is required to further reduce its import tariffs and other trade barriers over time, including with respect to certain categories of petroleum and crude oil.  At present, CNOOC, Sinopec, PetroChina and several other domestic state-owned enterprises have received permission to import crude oil on their own.  Foreign owned or foreign invested entities and other non-state-owned enterprises are subject to certain import quotas.
 
PRC Fiscal Regimes for Offshore Crude Oil and Natural Gas Activities
 
We conduct exploration and production operations either independently or jointly with foreign partners under our production sharing contracts.  The PRC government has established different fiscal regimes for crude oil and natural gas production from our independent operations and from the operations under our production sharing contracts.
 
Royalties paid to the PRC government are based on our gross production from both independent operations and oil and gas fields under production sharing contracts.  The amount of the royalties varies up to 12.5% based on the annual production of the relevant property.  The PRC government has provided companies such as us with a royalty exemption for up to one million tons, or approximately seven million BOE, per year for our crude oil production and for up to 70.6 billion cubic feet, or approximately 11.8 million BOE, per year for our natural gas production.  The limits in these exemptions apply to our total production from both independent properties and properties under production sharing contracts.  In addition, we pay production taxes to the PRC government equal to 5% of our crude oil and gas produced independently and under production sharing contracts. 
 
46

 
 
Under our production sharing contracts, production of crude oil and gas is allocated among us, the foreign partners and the PRC government according to a formula contained in the contracts.  Under this formula, a percentage of production under our production sharing contracts is allocated to the PRC government as its share oil.  For more information about the allocation of production under the production sharing contracts, see “Item 4—Information on the Company—Business Overview—Fiscal Regimes—Offshore China—Production Sharing Formula.”
 
Fiscal Regimes
 
Offshore China
 
When exploration and production operations offshore China are conducted through a production sharing contract, the operator of the oil or gas field must submit a detailed evaluation report upon discovery of petroleum reserves.  If such a discovery is determined commercially viable pursuant to the procedures set forth in the production sharing contract, an overall development plan must be submitted to a joint management committee established under the production sharing contract for its review and adoption.  After that, the overall development plan must also be submitted to CNOOC.  After CNOOC confirms the overall development plan, CNOOC submits it to the National Development and Reform Commission for approval.  After receiving the governmental approval, the parties to the production sharing contract may begin the commercial development of the oil and gas field.
 
As part of the reorganization in 1999, CNOOC transferred all of its rights and obligations under its then existing production sharing contracts to us and our subsidiaries.  It also undertook to transfer its future production sharing contracts to us and our subsidiaries. However, CNOOC retains all rights and obligations relating to its administrative functions. As of December 31, 2007, we had 40 production sharing contracts under implementation.
 
Under PRC law, the negotiation of a production sharing contract is a function that only a state-owned company, such as CNOOC, may perform.  This function cannot be transferred to us because we are a pure commercial entity.  Since the reorganization, under the terms of its undertaking with us, CNOOC, after entering into production sharing contracts with international oil and gas companies, is required to assign immediately to us all of its rights and obligations under the production sharing contracts except for those relating to CNOOC’s administrative functions.  For further details, see “Item 4—Information on the Company—History and Development” and “Item 7—Major Shareholders and Related Party Transactions—Related Party Transactions.”
 
New production sharing contracts are entered into between CNOOC and foreign partners primarily through bidding organized by CNOOC and direct negotiation.
 
Bidding Process
 
The bidding process typically involves the following steps:
 
 
·
CNOOC, with the approvals of the PRC government, determines which blocks are open for bidding and prepares geological information packages and bidding documentation for these blocks;
 
 
·
CNOOC invites foreign enterprises to bid;
 
47

 
 
·
potential bidders are required to provide information, including estimates of minimum work commitments, exploration costs and percentage of share oil payable to the PRC government; and
 
 
·
CNOOC evaluates each bid and negotiates a production sharing contract with the successful bidder.
 
Under CNOOC’s undertaking with us, we may participate with CNOOC in all negotiations of new production sharing contracts.
 
The term of a production sharing contract typically lasts for 30 years and has three distinct phases:
 
 
·
Exploration.  The exploration period is divided into three phases, with three, two and two years, respectively, and may be extended with the consent of CNOOC and the approval of relevant PRC regulatory authorities.  During this period, exploratory and appraisal work on the exploration block is conducted in order to discover petroleum and to enable the parties to determine the commercial viability of any petroleum discovery.
 
 
·
Development.  The development period begins on the date on which the relevant PRC regulatory authorities approve the overall development plan, which outlines the recoverable reserves and schedule for developing the discovered petroleum reserves.  The development phase ends when the design, construction, installation, drilling and related research work for the realization of petroleum production as provided in the overall development plan have been completed.
 
 
·
Production.  The production period begins when commercial production commences and usually lasts for 15 years.  The production period may be extended upon approval of the PRC government.
 
Minimum Work Commitment
 
Under production sharing contracts that involve exploration activities, the foreign partners must complete a minimum amount of work during the exploration period, generally including:
 
 
·
drilling a minimum number of exploration wells;
 
 
·
acquiring a fixed amount of seismic data; and
 
 
·
incurring a minimum amount of exploration expenditures.
 
Foreign partners are required to bear all exploration costs during the exploration period.  However, such exploration costs can be recovered according to the production sharing formula after commercial discoveries are made and production begins.  During the exploration period, foreign partners are required to relinquish 25% of the contract area, excluding the development and production areas, to CNOOC at the end of each phase of the exploration period.  At the end of the exploration period, all areas, excluding the development areas, production areas and areas under evaluation, must be relinquished to CNOOC.
 
Participating Interests
 
Pursuant to production sharing contracts, we have the right to take participating interests in any oil or gas field discovered in the contract area and may exercise this right after the foreign partners have made commercially viable discoveries.  The foreign partners retain the remaining participating interests.

Cost recovery oil allocated according to the following priority:
1. recovery of current year operating costs by us and foreign partner(s);
2. recovery of earlier exploration costs by foreign partner(s);
3. recovery of development costs and deemed interest by us and foreign partner(s) based on participating interests; and
4. any excess, allocated to the remainder oil.
     
32.5%(3)
 
Remainder oil allocated according to the following formula:
1. (1-X) multiplied by 32.5% represents share oil payable to the PRC government; and
2. X multiplied by 32.5% represents remainder oil distributed according to each partner’s participating interest.(4)

In this annual report and in our consolidated financial statements included elsewhere in this annual report, references to production tax on oil and gas produced offshore China are to the value-added tax set out in our production sharing contracts offshore China.
(2)
Assumes annual gross production of more than four million metric tons, approximately 30 million BOE.  For lower amounts of production, the royalty rate will be lower and the cost recovery will be greater than 50.0% by the amount that the royalty rate is less than 12.5%.
(3)
The ratio “X” is agreed in each production sharing contract based on commercial considerations and ranges from 8% to 100%.
(4)
See “Item 4—Information on the Company—Business Overview—Principal Oil and Gas Regions Offshore China” for our participating interest percentage in our production sharing contracts.
 
The first 5.0% of the annual gross production is paid to the PRC government as production tax.  The PRC government is also entitled to a royalty payment equal to the next 0% to 12.5% of the annual gross production as follows:

12.5%
 
 

(1)
The royalties for natural gas reach a maximum at 3.0%.
 
Depending on the percentage of the PRC government’s royalty payment, an amount equal to the next 50.0% to 62.5% of the annual gross production is allocated to the partners for cost recovery purposes.  This amount is allocated according to the following priority schedule:
 
 
·
recovery of operating costs incurred by the partners during the year;
 
 
·
recovery of exploration costs, excluding interest accrued thereon, incurred but not yet recovered by foreign partners during the exploration period; and
 
 
·
recovery of development investments incurred but not yet recovered, and interest accrued in the current year, according to each partner’s participating interest.
 
The remaining 32.5% of the annual gross production, which is referred to as the remainder oil, is distributed to each of the PRC government, us and the foreign partners according to a “ratio X” agreed to by CNOOC and the foreign partners in the production sharing contracts.  An amount of oil and gas equal to the product of the remainder oil and one minus the “ratio X” is first distributed to the PRC government as share oil.  The balance of the remainder oil, which is referred to as the allocable remainder oil, is then distributed to us and the foreign partners based on each party’s participating interest.
 
We pay production tax and royalty to the PRC government on a monthly basis for oil and natural gas production.  At the end of each month, we calculate the production tax and royalty payable and file this information with the PRC tax bureau for current month payment.  We make adjustments for any overpayment or underpayment of production tax and royalty at the end of the year.
 
The foreign partners have the right to either take possession of their allocable remainder oil for sale in the international market, or sell such crude oil to us for resale in the PRC market.
 
Management and Operator
 
Under each production sharing contract, a party will be designated as an operator to undertake the execution of the production sharing contract which includes:
 
 
·
preparing work programs and budgets;
 
 
·
procuring equipment and materials relating to operations;
 
 
·
establishing insurance programs; and
 
 
·
issuing cash-call notices to the parties to the production sharing contract to raise funds.
 
A joint management committee, which usually consists of six or eight persons, is set up under each production sharing contract to perform supervisory functions, and each of us and the foreign partners as a group has the right to appoint an equal number of representatives to form the joint management committee.  The chairman of the joint management committee is the chief representative designated by us and the vice chairman is the chief representative designated by the foreign partners as a group.  The joint management committee has the authority to make decisions on matters including:
 
 
·
reviewing and approving operational and budgetary plans;
 
 
·
determining the commercial viability of each petroleum discovery;
 
 
·
reviewing and adopting the overall development plan; and
 
 
·
approving significant procurements and expenditures, and insurance coverage.
 
Daily operations of a property subject to a production sharing contract are carried out by the designated operator.  The operator is typically responsible for determining and executing operational and budgetary plans and all routine operational matters.  Upon discovery of petroleum reserves, the operator is required to submit a detailed overall development plan to the joint management committee.
 
After the foreign partner has fully recovered its exploration and development costs under production sharing contracts in which the foreign partner is the operator, we have the exclusive right to take over the operation of the particular oil or gas field.  With the consent of the foreign partner, we may also take over the operation before the foreign partner has fully recovered its exploration and development costs.
 
 
 
Ownership of Data and Assets
 
All data, records, samples, vouchers and other original information obtained by foreign partners in the process of exploring, developing and producing offshore petroleum become the property of CNOOC as a state-owned oil company under PRC law.  Through CNOOC, we have unlimited and unrestricted access to the data.
 
Our foreign partners and we have joint ownership in all of the assets purchased, installed or constructed under the production sharing contract until either:
 
·  
the foreign partners have fully recovered their development costs, or
 
·  
upon the expiration of the production sharing contract.
 
After that, as a state-owned oil company under PRC law, CNOOC will assume ownership of all of the assets under the production sharing contracts; our foreign partners and we retain the exclusive right to use the assets during the production period.
 
Abandonment Costs
 
Any party to our production sharing contracts must give prior written notice to the other party or parties if it plans to abandon production of the oil or gas field within the contracted area.  If the other party or parties agree to abandon production from the oil or gas field, all parties pay abandonment costs in proportion to their respective percentage of participating interests in the field.  If we decide not to abandon production upon notice from a foreign partner, all of such foreign partner’s rights and obligations under the production sharing contract in respect of the oil or gas field, including the responsibilities for payment of abandonment costs, terminate automatically.  We bear the abandonment costs if we decide to abandon production after an initial decision to proceed with production.
 
Production Tax
 
The PRC production tax rate on the oil and natural gas produced under production sharing contracts is currently 5%.
 
Overseas
 
In addition to our production sharing contracts in the PRC, we are subject to other fiscal regimes in the foreign countries and regions where we conduct operations, including Indonesia, Australia and Nigeria. See “Item 4—Information on the Company—Business Overview—Overseas Activity.”
 
In Indonesia, Myanmar, Nigeria, Equatorial Guinea, and Kenya, we conduct our operations through production sharing contracts.  Our OML 130 project in Nigeria also involves a production sharing arrangement.  We and the other partners to overseas production sharing contracts are required to bear all exploration, development and operating costs according to our respective participating interests. Exploration, development and operating costs which qualify for recovery can be recovered according to the production sharing formula after commercial discoveries are made and production begins.
 
Our net interest in the production sharing contracts overseas consists of our participating interest in the properties covered under the relevant production sharing contracts, less oil and gas distributed to the local government and/or the domestic market obligation, as applicable.
 
In Australia, we conduct our operations through exploration and production permits or licenses.  We, as one of the title owners under these licenses or permits, are required to bear all exploration, development and operating costs together with other co-owners. Once production occurs, a certain percentage of the annual production or revenue will first be distributed to the local government, in most of cases in the form of a royalty, and the rest of the annual production or revenue will be allocated among the co-owners. Exploration, development and operating costs are deductible for the purpose of income tax calculation in accordance with local tax regulations.
 
 
 
Operating Hazards and Uninsured Risks
 
Our operations are subject to hazards and risks inherent in the drilling, production and transportation of crude oil and natural gas, including pipeline ruptures and spills, fires, explosions, encountering formations with abnormal pressures, blowouts, cratering and natural disasters, any of which can result in loss of hydrocarbons, environmental pollution and other damage to our properties and the properties of operators under production sharing contracts.  In addition, certain of our crude oil and natural gas operations are located in areas that are subject to tropical weather disturbances such as typhoons, some of which can be severe enough to cause substantial damage to facilities and interrupt production.
 
As protection against operating hazards, we maintain insurance coverage against some, but not all, potential losses, including the loss of wells, blowouts, pipeline leakage or other damage, certain costs of pollution control and physical damages on certain assets.  Our insurance coverage includes oil and gas field properties and construction insurance, marine hull insurance, protection and indemnity insurance, drilling equipment insurance, marine cargo insurance and third party and comprehensive general liability insurance.  The operators of the projects in which we participate overseas are required by local law to purchase insurance policies customarily taken out by international petroleum companies. As of December 31, 2007, we paid an annual insurance premium of approximately US$29.1 million and US$27.3 million for operational insurance and all risk construction insurance, respectively, to maintain our insurance coverage.  We believe that our level of insurance is adequate and customary for the PRC petroleum industry and international practices.  However, we may not have sufficient coverage for some of the risks we face, either because insurance is not available or because of high premium costs.  See “Item 3—Key Information—Risk Factors—Risks relating to our business—Exploration, development and production risks and natural disasters may affect our operations and could result in losses that are not covered by insurance.”
 
Research and Development
 
Historically, we used research and development services provided by CNOOC’s affiliates, including CNOOC Research Center, as well as other international research entities.  In July 2003, we established our own research center within our subsidiary, CNOOC (China) Limited, and in 2006, we established CNOOC China Limited, Beijing Research Center, to undertake most of our research and development activities.  During the years ended December 31, 2005, 2006 and 2007, our research and development costs were approximately Rmb 401.6 million, Rmb 377.1 million and Rmb 482.2 million, respectively.
 
Our research efforts have focused on:
 
·
enhancing oil recovery in offshore China oil fields;
 
·

Regulatory Framework
 
Government Control
 
The PRC government owns all of China’s petroleum resources and exercises regulatory control over petroleum exploration and production activities in China.  We are required to obtain various governmental approvals, including those from the Ministry of Land and Resources, the State Oceanic Administration, the National Development and Reform Commission and the Ministry of Commerce before we are permitted to conduct production activities.  Our sales are coordinated by the National Development and Reform Commission.  For joint exploration and production with foreign enterprises, we are required to obtain various governmental approvals, through CNOOC, including those from:
 
·  
the Ministry of Land and Resources, for a permit for exploration blocks, an approval of a reserve report submitted through CNOOC;
 
·  
the Ministry of Land and Resources or the National Development and Reform Commission to designate such blocks as an area for foreign cooperation;
 
·  
the Ministry of Commerce for the production sharing contracts between CNOOC and the foreign enterprises;
 
· 
the State Oceanic Administration for an environmental impact report submitted through CNOOC;
 
·  
the National Development and Reform Commission for an overall development plan submitted through CNOOC; and
 
· 
the Ministry of Land and Resources, for an extraction permit.
 
Special Policies Applicable to the Offshore Petroleum Industry in China
 
Since the early 1980s, the PRC government has adopted policies and measures to encourage the development of the offshore petroleum industry.  These policies and measures, which were applicable to CNOOC’s operations prior to the reorganization, became applicable to our operations in accordance with an undertaking agreement between us and CNOOC.  As approved by the relevant PRC government authorities, including the Ministry of Land and Resources and the Ministry of Commerce, these policies and measures have provided us with the following benefits:
 
·  
the exclusive right to explore for, develop and produce petroleum in designated areas offshore China in cooperation with international oil and gas companies and to sell petroleum in China;
 
·  
the flexibility to set our prices in accordance with international market prices and determine where to sell our crude oil, with only minimal supervision from the PRC government; and
 
·  
production from one of our major gas fields, Yacheng 13-1, is exempt from the PRC royalties under an approval by the State Tax Bureau granted in May 1989 and from the 5% production tax applicable to the oil and gas produced under other production sharing contracts in accordance with an approval by the Ministry of Finance granted in August 1985.  Our natural gas revenues from Yacheng 13-1 for each of  the three years ended December 31, 2005, 2006 and 2007 represented approximately 2.3%, 2.0% and 1.6%, respectively, of our total oil and natural gas sales in those years.
 
 
 
Although we historically have benefited from the foregoing special policies, we cannot assure that such policies will continue in the future.  We are also regulated by the PRC government in various other aspects of our business and operations, including required government approvals for new independent development and production projects and new production sharing contracts.  For a further discussion of ways in which we are regulated by the PRC government, see “Item 4—Information on the Company—Business Overview— Regulatory Framework—Government Control.”
 
In March 2006, the State Council issued the Decision to Impose a Special Oil Gain Levy and the Ministry of Finance promulgated the Management Rules on the Administration of Special Oil Gain Levy, effective March 26, 2006.  According to the rules, the Ministry of Finance imposes a special oil gain levy at progressive rates from 20% to 40% on any income derived from sales by an oil exploration and production company of locally produced crude oil at a price which exceeds US$40 per barrel.  The special oil gain levy is collected on a quarterly basis.  For the years ended December 31, 2006 and 2007, we incurred approximately Rmb 4.0 billion and Rmb 6.8 billion (US$937.3 million) in connection with the Special Oil Gain Levy.  As international oil prices, the exchange rate of Renminbi and our crude oil production fluctuate, we cannot ascertain the full impact of the Special Oil Gain Levy going forward.
 
In addition, the PRC government imposed an export tariff of 5% on crude oil in November 2006.
 
Policies Applicable to International Oil and Gas Companies Operating Offshore China
 
The PRC government encourages foreign participation in offshore petroleum exploration and production through exclusive cooperation with CNOOC.  In 1982, the State Council promulgated the Regulation of the People’s Republic of China on the Exploitation of Offshore Petroleum Resources in Cooperation with Foreign Enterprises, which grants to CNOOC the exclusive right to enter into joint cooperation arrangements with foreign enterprises for offshore petroleum exploration and production.  From 1982 to 2000, CNOOC successfully completed several rounds of bidding for offshore petroleum exploration and production projects, and many international oil and gas companies have been involved in  and awarded exploration blocks for joint exploration, development and production with CNOOC.
 
In October 2001, the State Council amended the regulation referred to above as a part of the comprehensive review of all business laws and regulations by the Chinese government to ensure compliance with its World Trade Organization commitments.  The amendment revised those terms in the law governing offshore exploration as restrictive provisions on technology transfers and domestic components requirements in procurement.  The removal of these restrictions will provide a level playing field for all oilfield service contractors, domestic or international. CNOOC will continue to enjoy the exclusive right to conduct production sharing contract activities with foreign contractors and is entitled to all rights and privileges under the previous regulation.  The regulation also states that CNOOC, as a state-owned enterprise, is to be in charge of all efforts to exploit petroleum resources with contractors in Chinese waters.  Currently, international oil and gas companies can only undertake offshore petroleum exploration and production activities in China after they have entered into a production sharing contract with CNOOC.
 
Environmental Regulation
 
Our operations are required to comply with various applicable environmental laws and regulations, including PRC laws and regulations administered by the central and local government environmental protection bureaus for our operations in China.  We are also subject to the environmental rules introduced by governments in whose jurisdictions our logistical support facilities are located.
 
Government agencies set national or local enviromental protection standards. The relevant environment protection bureau must approve or review each stage of a project.  We must file an environmental impact statement or, in some cases, an environmental impact assessment outline before an approval can be issued.  The filing must demonstrate that the project conforms to applicable environmental standards.  The relevant environmental protection bureau generally issues approvals and permits for projects using modern pollution control measurement technology.
 
 
The PRC national and local environmental laws and regulations impose fees for the discharge of waste substances above prescribed levels, require the payment of fines for serious violations and provide that the PRC national and local governments may at their own discretion close or suspend any facility which fails to comply with orders requiring it to cease or cure operations causing environmental damage.
 
The PRC environmental laws require offshore petroleum developers to pay abandonment costs.  Our financial statements include provisions for costs associated with the dismantlement of oil and gas fields during the years ended December 31, 2005, 2006 and 2007 of approximately Rmb 252.9 million, Rmb 472.3 million and Rmb 561.7 million, respectively.
 
Environmental protection and prevention costs and expenses in connection with the operation of offshore petroleum exploitation are covered under each individual production sharing contract.  Each platform has its own environmental protection and safety staff responsible for monitoring and operating the environmental protection equipment.  However, no assurance can be given that the PRC government will not impose new or stricter regulations which would require additional environmental protection expenditures.
 
We believe that our environmental protection systems and facilities comply with applicable national and local environmental protection regulations.
 
Patents and Trademarks
 
We own or have licenses to use two trademarks which are of value in the conduct of our business.  CNOOC is the owner of the two trademarks.  Under two non-exclusive license agreements between CNOOC and us, we have obtained the right to use the two trademarks for a nominal consideration.
 
Real Properties
 
Our corporate headquarters is located in Hong Kong.  We lease several other properties from CNOOC in China and Singapore.  The rental payments under these lease agreements are determined with reference to market rates.  See “Item 7—Major Shareholders and Related Party Transactions—Related Party Transactions.”
 
We own the following main property interests in the PRC:
 
·  
51% interest in land, various buildings and structures at Yacheng 13-1 Processing Plant, Hainan Province;
 
·  
51% interest in land, various buildings and structures at Yacheng 13-1 Processing Plant, Hong Kong;
 
·  
land, various buildings and structures at Xingcheng JZ 20-2 Natural Gas Separating Plant, Liaoning Province;

land, various buildings and structures located at Panyu Huizhou Gas Processing Plant, Guangdong Province; and
 
·  
land, various buildings and structures located at a Gas Processing Plant, Ningbo, Zhejiang Province.
 
Employees and Employee Benefits
 
During the years ended December 31, 2005, 2006 and 2007, we employed 2,696 persons, 2,929 persons and 3,288 persons, respectively.  Of the 3,288 employees we employed as of December 31, 2007, approximately 79.3% were involved in petroleum exploration, development and production activities, approximately 6.2% were involved in accounts and finance work and the remainder were senior management, coordinators of production sharing contracts and safety and environmental supervisors. Workers for the operation of the oil and gas fields, maintenance personnel and ancillary service workers are hired on a contract basis.
 
We have a union that:
 
·  
protects employees’ rights;
 
·  
organizes educational programs;
 
·  
assists in the fulfillment of economic objectives;
 
·  
encourages employee participation in management decisions; and
 
·  
assists in mediating disputes between us and individual employees.
 
We have not been subject to any strikes or other labor disturbances and believe that relations with our employees are good.
 
The total remuneration of employees includes salary, bonuses and allowances.  Bonus for any given period is based primarily on individual and our performance.  Employees also receive health benefits and other miscellaneous subsidies.
 
We have implemented an occupational health and safety program similar to that employed by other international oil and gas companies.  Under this program, we closely monitor and record health and safety incidents and promptly report them to government agencies and organizations.  On March 15, 2000, we finalized and implemented our occupational health and safety program.  We believe this program is broadly in line with the United States government’s Occupational Safety & Health Administration guidelines.
 
All full-time employees in the PRC are covered by a government-regulated pension.  The PRC government is responsible for the pension of these retired employees.  We are required to contribute monthly approximately 10% to 22% of our employees’ salaries, with each employee contributing 8% of his or her salary for retirement.  The contributions vary from region to region.
 
Our Indonesian subsidiaries employ approximately 888 employees, including approximately 40 expatriates. We provide benefits to expatriates that we believe to be in line with customary international practices.  Our local staff in Indonesia enjoy welfare benefits mandated by Indonesian labor laws.
 
For further details regarding retirement benefits, see note 31 to our consolidated financial statements included elsewhere in this annual report.
 
 
 
As an oil and gas exploration and production company operating in highly competitive markets, we depend in large part on our employees for effective and efficient operations.  We devote significant resources to train our employees.  During 2007, we held 5,471 training workshops, which were attended by 52,545 participants.  To ensure smooth implementation of our overseas strategy, we have established an international human resources system to attract and retain talent in the international market.   In order to enhance the planning and budget control of our labor costs, we have installed target benchmarks in performance appraisals to guide various business units to cut their labor costs and to increase the accuracy of their budgets.
 
Health, Safety and Environmental Policy
 
We are committed to the promotion of the concept and culture of health, safety and environmental (“HSE”) protection among all the staff.  We have safety compliance standards to facilitate enforcement of corporate social responsibilities, enhance the awareness of work safety, promote environmental protection during project implementation, and strengthen crisis management skills in our staff.  We also have HSE management standards for contractors.
 
We organize HSE training sessions for all staff from management to the operational level, covering such topics as HSE regulations, corporate values and policies, risk management and control, offshore rescue and special operations.  We also provide HSE training to the employees of our contractors.  In 2007, more than 30,000 people participated in such training during the year.  We also issue safety warnings, environmental protection information and health guidelines on a regular basis.
 
We conduct HSE reviews on our oil and gas field development projects for compliance with PRC requirements.  To strengthen our capability in handling oil spill emergencies, we periodically organize large-scale emergency drills that include our employees, offshore service contractors, transportation contractors and officials from relevant governmental authorities and have set up several oil spill response bases.
 
We also place considerable emphasis on safety in helicopter, diving and vehicle safety operations.  We hire professional auditors to conduct management audits on helicopter companies we engage and conduct safety checks on their helicopters.  We also conduct special audits on diving operations.
 
We have introduced a system of occupation health profiles in all our branches in order to strengthen the health management of offshore operating staff in addition to requiring them to submit health certificates.  The health data is to be analyzed so as to offer the staff proactive and constructive advice on health improvement.
 
In 2007, we were not involved in any material injury liability case.  We have never been subject to any safety-related liability claims for losses of over US$120,000.
 
We seek to align our operations with international standards and have been applying for the ISO14000 environmental management qualification for our oilfields.  By the end of 2007, our Qinhuangdao 32-6,Wenchang, Yacheng 13-1 and Liuhua 11-1 oilfields had been certified under the ISO14000 environmental management system.
 
In accordance with changes to the statistical requirements of the U.S. Occupational Safety and Health Administration (“OSHA”), we have revised our internal documentation procedures to comply with OSHA standards, which uses OGP reporting methods to record the differences and standards of particular incidents.  We use updated OSHA and incident reporting forms in order to better meet the requirements of international associations such as OGP and API. We deliver working hour statistics and incident reports to investors and API on a quarterly basis.

ITEM 5. OPERATING AND FINANCIAL REVIEW AND PROSPECTS
 
A.
 
You should read the following discussion and analysis in conjunction with our consolidated financial statements, selected historical consolidated financial data and operating and reserves data, in each case together with the accompanying notes, contained in this annual report.  Our consolidated financial statements have been prepared in accordance with Hong Kong GAAP, which differ in certain material respects from U.S. GAAP.  Note 39 to our consolidated financial statements included elsewhere in this annual report provides an explanation of our reconciliation to U.S. GAAP of profit and shareholders’ equity.  Certain statements set forth below constitute “forward-looking statements” within the meaning of the United States Private Securities Litigation Reform Act of 1995.  See “Forward-Looking Statements.”
 
 
 
Overview
 
We are an oil and gas company engaged in the exploration, development and production of crude oil and natural gas primarily offshore China.  We are the dominant producer of crude oil and natural gas offshore China and, through CNOOC, are the only company permitted to conduct exploration and production activities with international oil and gas companies offshore China.  As of December 31, 2007, we had estimated net proved reserves of 2,601.2 million BOE, comprised of 1,564.1 million barrels of crude oil and condensate and 6,222.8 billion cubic feet of natural gas.  In 2007, our net production averaged 371,827 barrels per day of crude oil, condensate and natural gas liquids and 559.6 million cubic feet per day of natural gas, which together totaled 469,407 BOE per day.
 
Our revenues and profitability are largely determined by our production volume and the prices we realize for our crude oil and natural gas, as well as the costs of our exploration and development activities.  Although crude oil prices depend on various market factors and have been volatile historically, our total net production volume has increased over the past few years.
 
The following table sets forth our net production and profit for the periods indicated.

Relationship with CNOOC
 
Prior to the reorganization of CNOOC in October 1999, our business and operations were conducted by CNOOC and its various affiliates.  In connection with the reorganization, CNOOC’s oil and gas exploration, development, production and sales business and operations conducted both inside and outside China were transferred to us.
 
Before the reorganization, certain PRC affiliates of CNOOC provided various materials, utilities and ancillary services for CNOOC’s exploration and production activities.  In connection with the reorganization, we entered into various agreements under which we continued to use various services and properties provided by these CNOOC affiliates and sell crude oil, condensate and liquified petroleum gas to CNOOC affiliates.  These agreements included: (i) a materials, utilities and ancillary services supply agreement; (ii) technical service agreements; (iii) agreements for the sale of crude oil, condensate oil and liquefied petroleum gas; (iv) various lease agreements; and (v) a research and development services agreement.  In 2005, in order to present a more coherent, logical and understandable picture to shareholders, and also to enable us to monitor the status of our related party/connected transactions more effectively going forward, we entered into new framework agreements with CNOOC and certain of its associates and adopted a new categorization for our transactions with these parties.  Under this new framework, we continue to receive services from CNOOC and its associates in connection with oil and natural gas exploration, development and production, marketing, management, technical and other ancillary matters and sell our crude oil, natural gas and other petroleum products to CNOOC and its associates.
 
For more information on our relationship with CNOOC, see “Item 4—Information on the Company—History and Development,” “Item 4—Information on the Company—Organizational Structure,” “Item 7—Major Shareholders and Related Party Transactions—Related Party Transactions,” and note 27 to our consolidated financial statements included elsewhere in this annual report.
 
 
 
 
Production Sharing Contracts Offshore China
 
We conduct a significant amount of our offshore China oil and gas activities through production sharing contracts with international oil and gas companies.  Under these production sharing contracts, our foreign partners are required to bear all exploration costs during the exploration period.  The parties to the contracts may recover exploration costs after commercial discoveries are made and production begins.  The amount of exploration costs recoverable is derived from a production sharing formula set forth in each contract.  Our production sharing contracts provide us with the option to take participating interests in properties covered by the production sharing contracts which we may exercise after the foreign partners have made viable commercial discoveries.  The foreign partners retain the remaining participating interests.  We and the foreign partners fund our development and operating costs according to our respective participating interests.  Based on a formula contained in the applicable contract, we are entitled to allocate specified amounts of the annual gross production of petroleum from those producing fields.  See “Item 4—Information on the Company—Business Overview—Fiscal Regimes—Offshore China—Production Sharing Formula.”
 
Before we exercise our option to take a participating interest in a production sharing contract, we do not account for the exploration costs incurred, as these costs were incurred by our foreign partners.  After we exercise the option to take a participating interest in a production sharing contract, we recognize our share of development costs, revenues and expenses from such operations based on our participating interest in the production sharing contracts.  See note 4 to our consolidated financial statements included elsewhere in this annual report.
 
The foreign partners have the right to either take possession of their petroleum for sale in the international market or sell their petroleum to us for resale in the PRC market.  See “Item 4—Information on the Company—Business Overview—Fiscal Regimes—Offshore China.”
 
As described above, production of crude oil and natural gas is allocated among us, our foreign partners and the PRC government according to a formula contained in the production sharing contracts.  We have excluded the government’s share oil from net sales in our historical consolidated financial statements.  Since our historical consolidated financial statements already exclude the government’s share oil from our net sales figure, we do not expect any future share oil payments to affect our results of operations or operating cash flows differently than the effects reflected in our historical consolidated financial statements.  For information regarding the historical amounts of government share oil payable to the government, see note 6 to our consolidated financial statements included elsewhere in this annual report.  For information regarding treatment of the PRC government’s share oil, see “Item 4—Information on the Company—Business Overview—Fiscal Regimes—Offshore China—Production Sharing Formula.”
 
Production from Independent Operations Offshore China Versus Production from Production Sharing Contracts Offshore China
 
Historically we have cooperated with foreign partners under production sharing contracts, which have provided us with the expertise to undertake our independent operations more effectively.  The percentage of our net production arising from independent operations offshore China was 50.2%, 52.9% and 53.5%, for the years ended December 31, 2005, 2006 and 2007, respectively.  Although we will continue to focus on independent operations, we plan to continue seeking appropriate opportunities to cooperate with foreign partners under production sharing contracts.
 
Our cost structures for production sharing contracts and for independent operations are different.  The total expenses per unit of production under production sharing contracts are generally higher due to our foreign partners’ use of expatriate staff, who generally command higher wages, as well as administrative and overhead costs that may be allocated by the operators and a larger proportion of imported equipment, which is more expensive.
 
 
 
Provision for Dismantlement
 
We estimate future dismantlement costs for oil and gas properties with reference to the estimates provided from either internal and external engineers after taking into consideration the anticipated method of dismantlement required in accordance with then current legislation and industry practice.  Provisions are made for present obligations, either legal or constructive. The associated cost is capitalized and the liability is discounted and accretion expense is recognized using the credit adjusted risk-free rate in effect when the liability is initially recognized.  The dismantlement costs for the years ended December 31, 2005, 2006 and 2007 were Rmb 252.9 million, Rmb 472.3 million and Rmb 561.7 million, respectively.  The accrued liability is reflected in our consolidated balance sheet under “provision for dismantlement.”  See note 28 to our consolidated financial statements included elsewhere in this annual report.
 
Production Imbalance
 
We account for oil overlifts and underlifts using the entitlement method, under which we record overlifts as liabilities and underlifts as assets.  An overlift occurs when we sell more than our percentage interest of oil from a property subject to a production sharing contract.  An underlift occurs when we sell less than our participating interest of oil from a property under a production sharing contract.
 
Allowances for Doubtful Accounts
 
We evaluate our accounts receivable by considering the financial condition of our customers, their past payment history and credit standing and other specific factors, including whether the accounts receivable in question are under dispute.  We make provisions for accounts receivable when they are overdue for six months and we are concerned about our ability to collect them.  For the years ended December 31, 2005, 2006 and 2007, allowances for doubtful accounts were not material in the context of total operating expenses and did not have a material effect on our results of operations or financial condition.
 
Critical Accounting Policies
 
We prepare our consolidated financial statements in accordance with Hong Kong GAAP.  The preparation of these financial statements requires management to make estimates and judgments that affect the reported amounts of our assets and liabilities, the disclosure of our contingent assets and liabilities as of the date of our financial statements and the reported amounts of our revenues and expenses during the periods reported.  Management makes these estimates and judgments based on historical experience and other factors that are believed to be reasonable under the circumstances.  Actual results may differ from these estimates under different assumptions or conditions.  We believe that the following significant accounting policies may involve a higher degree of judgment in the preparation of our consolidated financial statements.  For additional discussion of our significant accounting policies, see note 3 to our consolidated financial statements included elsewhere in this annual report.
 
 
Oil and Gas Properties
 
For oil and gas exploration, we have adopted the successful efforts method of accounting.  As a result, we capitalize initial acquisition costs of oil and gas properties and recognize impairment of initial acquisition costs based on exploratory experience and management judgment.  Upon discovery of commercial reserves, we transfer acquisition costs to proved properties and capitalize the costs of drilling and equipping successful exploratory wells, all development expenditure on construction, installation or completion of infrastructure facilities such as platforms, pipelines, processing plants and the drilling of development wells, including those renewals and betterments that extend the economic lives of the assets, and the related borrowing costs.  We treat the costs of unsuccessful exploratory wells and all other related exploration costs as expenses when incurred.  Productive oil and gas properties and other tangible and intangible costs of producing properties are amortised using the unit-of-production method on a property-by-property basis under which the ratio of produced oil and gas to the estimated remaining proved developed reserves is used to determine the provision of depreciation, depletion and amortization. Common facilities that are built specifically to service production directly attributed to designated oil and gas properties are amortized based on the proved developed reserves of the respective oil and gas properties on a pro-rata basis.  When applying the pro-rata basis of proved developed reserve allocation to the common facilities, we first calculate the amortization rate by dividing the total cost of the common facilities to be amortized by the total quantities of proved developed reserves of the relevant oil and gas properties.  Then we determine the amortization amount attributable to the respective oil and gas properties by multiplying the production volume of the respective oil and gas properties by the amortization rate.  Generally, common facilities that are not built specifically to service identified oil and gas properties are depreciated using the straight-line method over their estimated useful lives.  Costs associated with significant development projects are not depleted until commercial production commences and the reserves related to those costs are excluded from the calculation of depletion.  We amortize capitalized acquisition costs of proved properties by the unit-of-production method on a property-by-property basis based on the total estimated units of proved reserves.  We estimate future dismantlement costs for oil and gas properties with reference to the estimates provided from either internal or external engineers after taking into consideration the anticipated method of dismantlement required in accordance with current legislation and industry practices.  The associated cost is capitalized and the liability is discounted and an accretion expense is recognized using the credit-adjusted risk-free interest rate in effect when the liability is initially recognized.
 
Impairment of Assets
 
We make an assessment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable, or when there is any indication that an impairment loss previously recognized for an asset in prior years may no longer exist or may have decreased.  In any event, we would make an estimate of the asset’s recoverable amount, which is calculated as the higher of the asset’s value in use or its net selling price.  We recognize an impairment loss only if the carrying amount of an asset exceeds its recoverable amount.  We charge an impairment loss to the income statement in the period in which it arises. A reversal of an impairment loss is credited to the income statement in the period in which it arises.
 
Provisions
 
We recognize a provision when a present obligation (legal or constructive) has arisen as a result of a past event and it is probable that a future outflow of resources will be required to settle the obligation so long as a reliable estimate can be made of the amount of the obligation.  When the effect of discounting is material, the amount recognized for a provision is the present value at the balance sheet date of the future expenditures expected to be required to settle the obligation.  The increase in the discounted present value amount arising from the passage of time is included in finance costs in the income statement.  We make provisions for dismantlement based on the present value of our future costs expected to be incurred, on a property-by-property basis, in respect of our expected dismantlement and abandonment costs at the end of the related oil exploration and recovery activities.
 
Deferred Tax
 
Deferred tax is provided, using the liability method, on all temporary differences at the balance sheet date between the tax bases of assets and liabilities and their carrying amounts for financial reporting purposes.
 
 
62

 
Recognition of Revenue from Oil and Gas Sales and Marketing
 
We recognize revenue when it is probable that the economic benefits will flow to us and when the revenue can be measured reliably.  For oil and gas sales, our revenues represent the invoiced value of sales of oil and gas attributable to our interests, net of royalties and any government share oil that is lifted and sold on behalf of the PRC government.  Sales are recognized when the significant risks and rewards of ownership of oil and gas have been transferred to customers.  Oil and gas lifted and sold by us above or below our participating interests in any production sharing contract result in overlifts and underlifts.  We record these transactions in accordance with the entitlement method under which overlifts are recorded as liabilities and underlifts are recorded as assets at year-end oil prices.  Settlement will be in kind or in cash when the liftings are equalized.  We enter into gas sales contracts with customers which often contain take-or-pay clauses.  These clauses require our customers to take a specified minimum volume of gas each year.  If a customer fails to take the minimum volume of gas, the customer must pay for the gas even though it did not take the gas.  The customer can offset the deficiency payment against any future purchases in excess of the specified volume.  We record any deficiency payment as deferred revenue which is included in other payables until any make-up gas is taken by the customer or until the expiry of the contract.
 
Our marketing revenues represent sales of oil purchased from the foreign partners under our production sharing contracts and revenues from the trading of oil through our subsidiary in Singapore.  The title, together with the risks and rewards of the ownership of such oil purchased from the foreign partners, are transferred to us from the foreign partners and other unrelated oil and gas companies before we sell such oil to our customers.  The cost of the oil sold is included in crude oil and product purchases.
 
Accounting for Convertible Bonds
 
In July 2007, we renounced the cash settlement option related to the zero coupon guaranteed convertible bonds.  For conversion before the renunciation of the cash settlement option, the bifurcated derivative component was marked to market through earnings up to the conversion date. The host bond was accreted and any deferred issuance costs were amortized up to the conversion date as if bond were to remain outstanding for its contractual life. For those bonds that were converted, the accreted value of the host bond and the marked-to-market value of the derivative component were then reclassified into equity. Upon renunciation of the cash settlement option, the entire derivative component was marked to market and reclassified into equity. Subsequent conversions were accounted for in the same way but without considering the derivative component.

Calculation of Revenues
 
China
 
We report total revenues, which consist of oil and gas sales, marketing revenues and other income, in our consolidated financial statements included elsewhere in this annual report.  With respect to revenues derived from our offshore China operations, oil and gas sales represent gross oil and gas sales less royalties and share oil payable to the PRC government.  These amounts are calculated as follows:
 
·  
gross oil and gas sales consist of our percentage interest in total oil and gas sales, comprised of (i) a 100% interest in our independent oil and gas properties and (ii) our participating interest in the properties covered under our production sharing contracts, less an adjustment for production allocable to foreign partners under our production sharing contracts as reimbursement for exploration costs attributable to our participating interest;
 
·  
royalties represent royalties we pay to the PRC government on production with respect to each of our oil and gas fields.  The amount of royalties varies from 0% up to 12.5% based on the annual gross production of the relevant property.  We pay royalties on oil and gas we produce independently and under production sharing contracts;
 
 
 
· 
government share oil, which is only paid on oil and gas produced under production sharing contracts, is calculated as described under “Item 4—Information on the Company—Business Overview—Fiscal Regimes—Offshore China;” and
 
· 
we pay production taxes to the PRC government that are equal to 5% of the oil and gas we produce independently and under production sharing contracts.  Our oil and gas sales are not reduced by production taxes.  Production taxes are included in our expenses under “production taxes.”
 
Marketing revenues represent our sales of our foreign partners’ oil and gas produced under our production sharing contracts and purchased by us from our foreign partners under such contracts as well as from international oil and gas companies through our wholly owned subsidiary in Singapore.  Net marketing revenues represent the marketing revenues net of the cost of purchasing oil and gas from foreign partners and from international oil and gas companies.  Our foreign partners have the right to either take possession of their oil and gas for sale in the international market or to sell their oil and gas to us for resale in the PRC market.
 
Other income mainly represents project management fees charged to our foreign partners and handling fees charged to end customers—both fees are recognized when the services are rendered.  Reimbursement of insurance claims is recognized when the compensation becomes receivable.
 
Our share of the oil and gas sales of an unconsolidated investee is not included in our revenues, but our share of the profit or loss of this company is included in our consolidated statements of income under “share of profit of associates.”
 
Indonesia
 
The oil and gas sales from our subsidiaries in Indonesia consist of our participating interest in the properties covered under the relevant production sharing contracts, less adjustments for oil and gas distributable to the Indonesian government under our Indonesian production sharing contracts and for a domestic market obligation under which the contractor must sell a specified percentage of its crude oil to the local Indonesian market at a reduced price.
 
Australia
 
The oil and gas sales from our subsidiaries in Australia consist of our participating interest in the properties of the North West Shelf project.
 
2007 versus 2006
 
Consolidated Net Profit
 
Our consolidated net profit increased 1.1% to Rmb 31,258.3 million (US$4,285.1 million) in 2007 from Rmb 30,926.9 million in 2006.
 
Revenue
 
Our oil and gas sales increased 7.7% to Rmb 73,036.9 million (US$10,012.5 million) in 2007 from Rmb 67,828.0 million in 2006. The increase was primarily attributable to higher oil prices in 2007. The average realised price for our crude oil increased US$7.36 per barrel, or 12.5%, to US$66.26 per barrel in 2007 from US$58.90 per barrel in 2006. We sold 134.6 million barrels of crude oil in 2007, representing a decrease of 0.6% from 135.4 million barrels in 2006. The average realised price for our natural gas increased US$0.25 per thousand cubic feet, or 8.7%, to US$3.30 per thousand cubic feet in 2007 from US$3.05 per thousand cubic feet in 2006. Sales volume of our natural gas increased 16.1% to 34.7 million BOE in 2007 from 29.9 million BOE in 2006.
 
 
 
Our net marketing profit, which is marketing revenue less purchase costs, decreased 19.6% to Rmb 314.7 million (US$43.1 million) from Rmb 391.2 million in 2006. Our realised marketing profit margin, which is our net marketing profit as a percentage of marketing revenues, was 1.8%, relatively unchanged from 2006. In 2007, over 86% of our revenues was contributed by customers located in China, with the remainder generated from overseas.
 
Expenses
 
Operating expenses.  Our operating expenses increased 14.9% to Rmb 8,039.6 million (US$1,102.1 million) in 2007 from Rmb 6,999.2 million in 2006. Operating expenses per BOE increased 11.8% to Rmb 47.3 (US$6.48) per BOE in 2007 from Rmb 42.3 per BOE in 2006. Operating expenses per BOE offshore China increased 11.4% to Rmb 38.6 (US$5.29) per BOE in 2007 from Rmb 34.6 per BOE in 2006, primarily as a result of higher service fees and raw material prices. Operating expenses per BOE overseas decreased 4.6% to Rmb 104.7 (US$14.35) per BOE in 2007 from Rmb 109.8 per BOE in 2006, primarily as a result of the increased production volume of the North West Shelf project in Australia, which has a lower than average cost structure among our overseas operations.
 
Production taxes.  Our production taxes increased 5.5% to Rmb 3,497.4 million (US$479.5 million) in 2007 from Rmb 3,315.7 million in 2006, primarily as a result of increased oil and gas sales.
 
Exploration costs.  Our exploration costs increased 101.3% to Rmb 3,432.4 million (US$470.5 million) in 2007 from Rmb 1,705.1 million in 2006. Exploration costs incurred offshore China and overseas increased 50.0% and 268.6%, respectively.  In 2007, we continued to invest substantial human resources and capital in exploration activities, with a higher level of geological and geophysical activities.
 
Depreciation, depletion and amortization.  Our depreciation, depletion and amortisation increased 6.4% to Rmb 7,374.5 million (US$1,011.0 million) in 2007 from Rmb 6,933.2 million in 2006. Our average depreciation, depletion and amortisation per barrel increased 3.6% to Rmb 43.4 (US$5.95) per BOE in 2007 from Rmb 41.9 per BOE in 2006, primarily as a result of the commencement of production of oil and gas fields in 2006 and 2007.
 
Dismantlement.  Our dismantling expenses increased 18.9% to Rmb 561.7 million (US$77.0 million) in 2007 from Rmb 472.3 million in 2006, primarily as a result of the reevaluation of work commitments, higher service fees and raw material prices. Our average dismantling costs increased to Rmb 3.3 (US$0.45) per BOE in 2007 from Rmb 2.9 per BOE in 2006.
 
Special Oil Gain Levy.  Our Special Oil Gain Levy increased 71.7% to Rmb 6,837.2 million (US$937.3 million) in 2007 from Rmb 3,981.2 million in 2006, primarily as a result of our higher average realised oil price and the corresponding progressive rates imposed under the levy. In addition, as the levy was implemented in March 2006, we were subject to the levy for less than a full year in 2006.
 
Impairment losses related to property, plant and equipment.  Our impairment losses increased 143.1% to Rmb 613.5 million (US$84.1 million) in 2007 from Rmb 252.4 million in 2006, primarily as a result of an expected increase in future capital expenditures and a lower reserve estimation with respect to an oil and gas field overseas.
 
Selling and administrative expenses.  Our selling and administrative expenses increased 12.8% to Rmb 1,741.2 million (US$238.7 million) in 2007 from Rmb 1,543.8 million in 2006. Selling and administrative expenses for our offshore China operations increased 15.8% to Rmb 8.2 (US$1.12) per BOE in 2007 from Rmb 7.0 in 2006, primarily as a result of higher prices in the PRC and share options expense recognised in 2007. Selling and administrative expenses for our overseas operations decreased 22.5% to Rmb 13.4 (US$1.84) per BOE in 2007 from Rmb 17.3 per BOE in 2006, primarily as a result of the increased production volume of the North West Shelf project in Australia, which has a lower than average cost structure among our overseas operations.
 
 
Finance costs, net of interest income
 
Our net finance costs increased 10.9% to Rmb 2,031.8 million (US$278.5 million) in 2007 from Rmb 1,832.1 million in 2006, primarily as a result of losses on fair value changes of the embedded derivative component of our convertible bonds and the effect of an increase in the amount of our provision for dismantlement arising from the passage of time.  Our interest income decreased 13.9% to Rmb 673.0 million in 2007 from Rmb 781.5 million in 2006, primarily as a result of an increase in financial investments in our short term asset portfolio.
 
Exchange gains/losses, net
 
Our net exchange gains incurred in 2007 were Rmb 1,856.0 million (US$254.4 million), representing an increase of Rmb 1,547.6 million from net exchange gains of Rmb 308.4 million in 2006. Compared with 2006, the significantly increased exchange gains mainly came from dividends receivable from a subsidiary and active changes in the currency structure of our asset portfolio in response to the ongoing appreciation of Rmb during 2007.
 
Investment income
 
Our investment income increased Rmb 289.4 million, or 47.2%, to Rmb 902.4 million (US$123.7 million) in 2007 from Rmb 613.0 million in 2006, primarily as a result of realised gain from sales of investment funds and the shares of well-known publicly listed companies.
 
Share of profits of associates
 
Primarily as a result of the good performance of one of our associate companies, CNOOC Finance Corporation Limited, our share of profits of associates increased 123.5% to Rmb 719.0 million (US$98.6 million) in 2007 from Rmb 321.7 million in 2007.
 
Non-operating income/expenses, net
 
Our net non-operating expenses for 2007 was Rmb 7.0 million (US$1.0 million), and our net non-operating income for 2006 was Rmb 876.4 million. The decrease was primarily the result of a tax refund in 2006 in connection with re-investment in the PRC.
 
Income tax
 
Our income tax expense decreased 8.7% to Rmb 12,052.3 million (US$1,652.2 million) in 2007 from Rmb 13,196.3 million in 2006, primarily as a result of the deferred tax liability effect of the implementation of a tax rate decrease from 30% to 25% under the PRC Corporate Income Tax Law effective on January 1, 2008. Our effective tax rate for 2007 was 27.8%, versus 29.9% in 2006.
 
2006 versus 2005
 
Consolidated Net Profit
 
Our consolidated net profit was Rmb 30,926.9 million in 2006, representing an increase of Rmb 5,603.8 million, or 22.1%, from Rmb 25,323.1 million in 2005.
 
Revenue
 
Income from our oil and gas sales for 2006 was Rmb 67,828.0 million, representing an increase of Rmb 14,410.3 million, or 27.0%, from Rmb 53,417.7 million in 2005. The increase was attributable to the high oil price, while growth in production also contributed to our higher profits. The average realized price for our crude oil was US$58.90 per barrel in 2006, representing an increase of US$11.59, or 24.5%, from US$47.31 per barrel in 2005. Sale of crude oil amounted to 135.4 million barrels, representing an increase of 4.3% over 2005. The average realized price for our natural gas was US$3.05 per thousand cubic feet in 2006, representing an increase of US$0.23 per thousand cubic feet, or 8.2%, from US$2.82 per thousand cubic feet in 2005. At the same time, sales volume of our natural gas increased by 27.8% from 23.4 million BOE in 2005 to 29.9 million BOE in 2006.
 
 
 
In 2006, our net marketing profit, which was derived from marketing revenue less purchase cost of crude oil and oil products, was Rmb 391.2 million, representing an increase of Rmb 193.9 million, or 98.3%, from Rmb 197.2 million in 2005. Since we are one of the companies that have the right to sell crude oil in China, upon request by our production sharing contract partners, we may purchase the oil of these partners for sale in China. However, the amount of oil we may purchase and sell in China depends on our foreign partners and, therefore, we cannot control the amount of crude oil that we are able to sell for any specific period. In 2006, marketing revenue from our wholly owned subsidiary, CNOOC China Limited, was Rmb 15,867.6 million, representing an increase of Rmb 6,436.8 million from Rmb 9,430.8 million in 2005. The net marketing profit was Rmb 203.4 million, increased 139.3% from 2005 due to the significant increase in sales volume in local market. Marketing revenue from our wholly owned subsidiary, China Offshore Oil (Singapore) International Pte Ltd, was Rmb 5,096.5 million. Netting off purchase cost of crude oil and oil production, the net marketing profit was Rmb 187.8 million, or 67.3% increased from the same period in 2005.
 
Our other income, reported on a net basis, was derived from our other income, which mainly represents project management fees charged to foreign partners and handling fees charged to customers, less corresponding costs. In 2006, our net other income was Rmb 37.9 million, representing a decrease of Rmb 21.8 million from Rmb 59.7 million in 2005. The decrease was primarily due to higher service fees relating to production sharing contract projects.
 
Expenses
 
Operating expenses.  Our operating expenses in 2006 were Rmb 6,999.2 million, representing an increase of Rmb 1,064.6 million, or 17.9%, from Rmb 5,934.6 million in 2005. The increase was mainly attributable to the commencement of production of new oil and gas fields in 2006. Operating expenses in 2006 were Rmb 42.3 per BOE, representing an increase of 9.1% from Rmb 38.8 per BOE in 2005. Operating expenses for our offshore China operations in 2006 were Rmb 34.6 per BOE, representing an increase of 6.6% from 2005. Operating expenses for our offshore Indonesia operations in 2006 were Rmb 119.3 per BOE, representing an increase of 19.1% from 2005. Besides the increase of service fees, supply vessels, equipment lease, chemicals and fuel, resulting from the higher international crude oil price, the maintenance and repair cost increased due to the effect of typhoons.
 
Production taxes.  Our production taxes for 2006 were Rmb 3,315.7 million, representing an increase of Rmb 719.2 million, or 27.7%, from Rmb 2,596.5 million in 2005. The increase was mainly due to the increased income from oil and gas sales.
 
Exploration costs.  Our exploration costs for 2006 were Rmb 1,705.1 million, representing an increase of Rmb 411.4 million, or 31.8%, from Rmb 1,293.7 million in 2005, as a result of increased exploration activities.
 
Depreciation, depletion and amortization.  Our depreciation, depletion and amortization for 2006 were Rmb 6,933.2 million, representing an increase of Rmb 968.5 million, or 16.2%, from Rmb 5,964.7 million in 2005. On a unit of production basis, depreciation, depletion and amortization expenses for 2006 were Rmb 41.9 per BOE, as compared to Rmb 39.0 per BOE in 2005, representing an increase of 7.4% from 2005. The increase was mainly attributable to the commencement of production of new oil and gas fields during 2006.
 
Dismantlement.  Our dismantling costs for 2006 were Rmb 472.3 million, representing an increase of Rmb 219.4 million from Rmb 252.9 million in 2005. The increase was primarily due to the increased dismantling costs resulting from the reevaluation of workload and the higher service fees resulting from the higher international crude oil price. Our average dismantling costs were Rmb 2.9 per BOE, which increased from Rmb 1.7 per BOE in 2005.
 
 
 
Special Oil Gain Levy.  During 2006, a Special Oil Gain Levy was imposed by the Ministry of Finance of the PRC at progressive rates from 20% to 40% on any income derived from sales of locally produced crude at a price which exceeds US$40 per barrel. The amount paid pursuant to this levy can be claimed as a deductible expense for corporate income tax purpose and is calculated based on the actual volume of the crude oil entitled.  For the year ended December 31, 2006, we incurred approximately Rmb 4.0 billion in connection with the Special Oil Gain Levy.
 
Impairment losses related to property, plant and equipment.  Due to the downward revision of the reserve of HZ19-1/2/3 oil fields and the postponement of PY 30-1 gas project, we recognised Rmb 252.4 million of impairment losses in 2006.
 
Selling and administrative expenses.  Our selling and administrative expenses for 2006 were Rmb 1,543.8 million, representing an increase of Rmb 173.4 million, or 12.7%, from Rmb 1,370.4 million in 2005. Of which, the selling and administrative expenses of companies in China in 2006 were Rmb 7.0 per BOE, representing an increase of 11.8% from 2005. Compared with 2005, the increase was mainly attributable to the staff and workers bonus and welfare fund accrued and expense for newly granted options recognized in 2006.
 
Finance costs, net of interest income
 
Our net finance costs for 2006 were Rmb 1,050.6 million, representing an increase of 41.7% from the net finance costs of Rmb 741.2 million in 2005. On one hand, our interest income increased Rmb 422.2 million from Rmb 359.3 million in 2005 to Rmb 781.5 million in 2006. On the other hand, the finance costs increased significantly mainly due to the losses on fair value changes of the embedded derivative component of the convertible bonds and the effect of increased amount of provision of dismantlement arising from the passage of time. The increases due to the factors mentioned above were Rmb 1,150.2 million, and Rmb 52.0 million respectively.
 
Exchange gains/losses, net
 
Our net exchange gains incurred in 2006 were Rmb 308.4 million, representing an increase of Rmb 21.4 million from net exchange gains of Rmb 287.0 million in 2005. Compared with 2005, the increased exchange gains mainly came from the Chinese government’s efforts on the improvement of rate-forming mechanism and the ongoing appreciation of Renminbi in 2006.
 
Investment income
 
Our investment income for 2006 was Rmb 613.0 million, representing a significant increase of Rmb 365.1 million, or 147.3%, from Rmb 247.9 million in 2005. For the purpose of improving the performance of our current assets portfolio, we increased the investment in financial instruments such as money market funds and other equity instruments. Benefiting from the structural changes in the investment portfolio and the influence from the market, we obtained a favorable return in 2006.
 
Share of profits of associates
 
In 2006, there were gains from our investments in unconsolidated investees of Rmb 321.7 million, representing an increase of 4.8% from 2005.
 
Non-operating income/expenses, net
 
Our net non-operating income for 2006 was Rmb 876.4 million, as compared to non-operating income of Rmb 28.6 million for 2005. In 2006, non-operating income primarily arose from tax refunds from re-investment in China.
 
 
Income tax
 
Our income tax for 2006 was Rmb 13,196.3 million, representing an increase of Rmb 2,218.5 million, or 20.2%, from Rmb 10,977.8 million in 2005. The primary reason for the increase was the increase in profit before tax. The effective tax rate for 2006 was 29.9%, slightly lower than the effective rate of 30.2% in 2005.

Cash Provided by Operations
 
Net cash generated from operating activities in 2007 amounted to Rmb 42,712.6 million (US$5,855.3 million), representing an increase of Rmb 3,487.0 million, or 8.9%, from Rmb 39,225.6 million in 2006.
 
Cash generated from operations increased mainly due to an increase in non-cash items such as depreciation, depletion and amortization expenses and impairment losses related to property, plant and equipment of Rmb 802.4 million (US$110.0 million).
 
The increase of cash flow was also partially offset by an increase of share of profit of associates of Rmb 397.4 million, a decrease of profit before tax of Rmb 812.6 million and an increase of net exchange gains of Rmb 1,547.3 million.
 
Compared with 2006, the increase in operating cash flow was partially attributable to the increase in changes of working capital of Rmb 3,948.1 million. In addition, an increase of investment income received of Rmb 396.4 million and a decrease in income taxes paid of Rmb 1,133.5 million also contributed to the increase of net cash inflow from operating activities.
 
Capital Expenditures and Investments
 
Net cash outflow from investing activities in 2007 was Rmb 22,939.0 million (US$3,144.7 million), representing a decrease of Rmb 16,586.6 million, or 42.0%, from Rmb 39,525.6 million in 2006.
 
Our total capital expenditures and investments primarily include successful exploration and development expenditures and purchases of oil and gas properties. Total capital expenditures were Rmb 26,942.1 million (US$3,693.4 million) in 2007, representing a decrease of Rmb 17,274.5 million, or 39.1%, from Rmb 44,216.6 million in 2006. Our development expenditures in 2007 mainly related to the development of OML130, Penglai 19-3 Phase II, Luda 22-1, Bozhong 34-1, Liuhua 11-1 and Xijiang 23-1 oil and gas fields. Compared with 2006, there were no significant merger and acquisition expenditures.
 
In addition, our cash inflow was attributable to the time deposits with maturities over three months of Rmb 2,032.8 million (US$278.7 million) and our net proceeds from sales of available-for-sale financial assets and disposals of property, plant and equipment of Rmb 8,577.3 million (US$1,175.8 million). Our cash outflow was attributable to the purchases of held-to-maturity financial assets of Rmb 3,000.0 million (US$411.3 million) and available-for-sale financial assets of Rmb 3,607.0 million (US$472.8 million).
 
 
 
For 2008, we have budgeted approximately US$5.9 billion for capital expenditures. The following table sets forth actual or budgeted capital expenditures on an accrual basis for our key operating areas for the periods indicated.

Figures for 2005, 2006 and 2007 represent our actual spending for capital expenditure purposes, including expensed exploration costs.
(2)
Figures for 2008 represent our budgeted capital expenditures.

In addition to the budgeted development and exploration expenditures relating to the oil and gas properties described above, we may make additional capital expenditures and investments consistent with our business strategy.  See “Item 4—Information on the Company—Business Overview—Business Strategy.”  We expect to fund our capital expenditures with our cash flows from operations and our borrowings.
 
Our ability to maintain and grow our revenues, profit and cash flows depends upon continued capital spending.  Generally, we adjust our capital expenditure and investment budget on an annual basis.  Our capital expenditure plans are subject to a number of risks, contingencies and other factors, some of which are beyond our control.  Therefore, our actual future capital expenditures and investments will likely be different from our current planned amounts, and such differences may be significant.  See “Item 3—Key Information—Risk Factors—Risks relating to our business—Our future prospects largely depend on our capital expenditure plans, which are subject to various risks.”
 
Financing activities
 
Our net cash outflow arising from financing activities in 2007 was Rmb 10,645.8 million (US$1,495.4 million), versus a net cash inflow of Rmb 6,038.6 million in 2006, representing a net increase of cash outflow of Rmb 16,684.4 million from 2006. In 2007, our net cash outflow was mainly due to the distribution of dividends of Rmb 11,523.7 million (US$1,579.8 million), and the repayment of bank loans of Rmb 17.8 million (US$2.4 million). It was partially offset by cash inflow, which was mainly contributed by bank borrowings of Rmb 895.7 million (US$122.8 million).
 
 
 
Our gearing ratio, which is interest bearing debt divided by interest bearing debt plus equity, was 7.9% as of December 31, 2007.
 
In 2006 and 2007, we, together with our partners on the Tangguh LNG project, borrowed bank loans amounting to approximately US$2.6 billion and US$884 million, respectively, for the purpose of financing the Tangguh LNG project in Indonesia. We shared in these bank loans in proportion to our 16.95688% interest in the project, or approximately US$593.3 million, of which our share of the utilized bank loans amounted to approximately US$248.2 million as of December 31, 2006, and approximately US$370.8 million as of December 31, 2007. These utilized loans are unsecured, bear interest at LIBOR + 0.23% through 0.38% per annum and have a final maturity of 2021.
 
We, as guarantor, have delivered a guarantee dated October 29, 2007 in favor of Mizuho Corporate Bank, Ltd., as facility agent for and on behalf of various international commercial banks under a US$884 million commercial loan agreement dated October 29, 2007 in connection with the Tangguh LNG project in Indonesia.  Pursuant to the guarantee, we guarantee the payment obligations of the trustee borrower under the subject loan agreement and are subject to a maximum cap of approximately US$164.9 million (Rmb 1.2 billion).  Together with the loan agreement dated July 31, 2006 with a maximum cap of approximately US$487.9 million, the total maximum guarantee cap is approximately US$652.8 million (Rmb 4.8 billion).
 
On February 21, 2008, CNOOC Finance (2004) Limited extinguished all the outstanding convertible bonds by exercising an early redemption option. The withdrawal of delisting of the convertible bonds on Hong Kong Stock Exchange was effective at the close of business on March 6, 2008. We currently have no convertible bond liability.
 
We have debt service obligations consisting of principal and interest payments on our outstanding indebtedness.  The following table summarizes the maturities of our long-term debt outstanding as of December 31, 2007.  As of the date this annual report is filed, we have not incurred any material long-term debt since December 31, 2007.

As of May 30, 2008, we had total foreign currency debt of US$1,404.7 million, all of which is in U.S. dollars.
 
As of December 31, 2007, we had unutilized banking facilities amounting to approximately Rmb 46,997.1 million (US$6,442.7 million) as compared to Rmb 47,040.9 million as of December 31, 2006.
 
In 2005, 2006 and 2007, we paid dividends totaling Rmb 7,772.2 million, Rmb 9,813.7 million and Rmb 11,523.7 million (US$1,579.8 million), respectively.  The payment and the amount of any dividends in the future will depend on our results of operations, cash flows, financial condition, the payment by our subsidiaries of cash dividends to us, future prospects and other factors which our directors may consider relevant.  The amount of dividends we paid historically is not indicative of the dividends that we will pay in the future.
 
 
We believe our future cash flows from operations, borrowing capacity and funds raised from our debt offerings will be sufficient to fund planned capital expenditures and investments, debt maturities and working capital requirements through at least 2008.  However, our ability to obtain adequate financing to satisfy our capital expenditures and debt service requirements may be limited by our financial condition and results of operations and the liquidity of international and domestic financial markets.  See “Item 3—Key Information—Risk Factors—Risks relating to our business—Our future prospects largely depend on our capital expenditure plans, which are subject to various risks”.
 
Employee Benefits
 
As part of its reorganization in October 1999, CNOOC retained all liabilities for retirement benefits for its employees, both former and current, who had not been transferred to us.  As compensation for CNOOC’s retention of liabilities for retirement benefits payable to approximately 7,000 retired CNOOC employees who were previously engaged in the oil and gas business that was transferred to us under the reorganization, we made a one-time payment to CNOOC of Rmb 1,660.0 million in 2001.
 
All of our full-time employees in the PRC are covered by a government-regulated pension plan and are entitled to an annual pension at their retirement dates.  The PRC government is responsible for the pension liabilities to these retired employees under this government pension plan.  The actual pension payable to each retiree is subject to a formula based on the status of the individual pension account, general salary and inflation movements.  We are required to make annual contributions to the government pension plan at rates ranging from 10% to 22% of our employees’ salaries.  The related pension costs are expensed as incurred.
 
The expenses attributable to mandatory contributions under the current government pension plan are included in our historical consolidated income statements under either operating expenses for our production staff or selling and administrative expenses for our administrative staff.  We expect that, under the current PRC laws and regulations regarding employee retirement benefits, the future costs of the current government pension plan will be comparable to our historical costs, subject to customary increases largely in line with salary increases of our employees.
 
We are required to make contributions to a mandatory provident fund at a rate of 5% of the base salaries for full-time employees in Hong Kong. The costs are expensed as incurred.
 
Our Indonesian subsidiaries employ approximately 888 employees, including approximately 40 expatriates.  We provide benefits to expatriates that we believe to be in line with customary international practices.  Our local staff in Indonesia enjoy welfare benefits mandated by Indonesia labor laws.
 
Holding Company Structure
 
We are a holding company.  Our entire petroleum exploration, development, production and sales business in the PRC is owned and conducted by CNOOC China Limited, our wholly foreign-owned enterprise in the PRC.  Our entire petroleum exploration, development and production business outside the PRC is owned and conducted by CNOOC International Limited, our wholly owned subsidiary incorporated in the British Virgin Islands.  International sales of crude oil are conducted by China Offshore Oil (Singapore) International Pte Ltd, our wholly owned subsidiary incorporated in Singapore.  Accordingly, our future cash flows will consist principally of dividends from our subsidiaries.  The subsidiaries’ ability to pay dividends to us is subject to various restrictions, including legal restrictions in their jurisdictions of incorporation.  For example, legal restrictions in the PRC permit payment of dividends only out of profit determined in accordance with PRC accounting standards and regulations.  In addition, under PRC law, CNOOC China Limited is required to set aside a portion of its profit each year to fund certain reserve funds.  These reserves are not distributable as cash dividends.
 
 
Inflation/Deflation
 
According to the China Statistical Bureau, as represented by the general consumer price index, China experienced an overall inflation rate of 1.8% in 2005, an overall inflation rate of 1.5% in 2006, and an overall inflation rate of 4.8% in 2007.  Neither deflation nor inflation has had a significant impact on our results of operations in the respective years.
 
U.S. GAAP Reconciliation
 
Our consolidated financial statements are prepared in accordance with Hong Kong GAAP, which differ in certain material respects from U.S. GAAP.  These differences relate primarily to the treatment of impairment of long-lived assets and the treatment for convertible bonds.  For differences between Hong Kong GAAP and U.S. GAAP that affect our profit or shareholders’ equity, please refer to note 39 to our consolidated financial statements included elsewhere in this annual report.
 
Taxation
 
We are subject to income taxes on an entity basis on income arising in or derived from the tax jurisdictions in which we and each of our subsidiaries are domiciled and operate.  We are subject to profits tax at a rate of 17.5% on profits arising in or derived from Hong Kong.  Pursuant to a notice issued by the State Administration of Taxation in March 2001, we are entitled to all tax benefits conferred by Chinese law on foreign invested enterprises.
 
Before January 1, 2008, our PRC subsidiary, as a wholly foreign owned enterprise, was exempted from the 3% local surcharges of the enterprise income tax, reducing its enterprise income tax rate from 33% to 30%.
 
In March 2007, the National People’s Congress of the PRC adopted new tax legislation, the PRC Corporate Income Tax Law, which became effective on January 1, 2008. This new tax legislation introduced a wide range of changes, including the unification of the income tax rate for domestic-invested and foreign-invested enterprises, including our PRC subsidiary, at 25%.
 
As a result of this tax rate change, we estimate that the change in corporate income tax rates had the following impact on our results and financial position for the year ended December 31, 2007: 
 
  RMB’000
Decrease in income tax expenses
1,019,564
Decrease in deferred tax liability
1,019,564

The PRC enterprise income tax is levied based on taxable income including income from operations as well as other components of earnings, as determined in accordance with the generally accepted accounting principles in the PRC (“PRC GAAP”).
 
Besides income taxes, our PRC subsidiary also pays certain other taxes, including:
 
·  
production taxes equal to 5% of independent production and production under production sharing contracts;
 
·  
export tariffs on crude oil of 5%, levied beginning November 1, 2006; and
 
·  
business tax of 3% to 5% on other income.
 
Our subsidiary in Singapore, China Offshore Oil (Singapore) International Pte Ltd, is subject to income tax at the rate of 10% and 20% for its oil trading activities and other income-generating  activities, respectively.
 
 
 
Our subsidiaries owning interests in oil and gas properties in the Malacca Strait in Indonesia are subject to corporate and dividend tax at the rate of 44%.
 
Certain of our oil and gas interests in Indonesia are held through Labuan incorporated companies. Labuan incorporated companies enjoy certain current reduced tax rates provided by the tax treaty between Indonesia and Malaysia. According to the current tax treaty between Indonesia and Malaysia, our subsidiaries owning interests in oil and gas properties in Indonesia are subject to corporate and dividend tax combined at rates ranging from 43.125% to 51.875%. In May 2006, certain proposed amendments to the tax treaty were agreed by the respective ministers of the two countries. According to the proposed amendments, the tax rates will increase from 43.125% to 48% and from 51.875% to 56% respectively. The proposed amendments will need to be ratified by the two countries and will take effect two months after the ratification. It is still uncertain when the ratification will be completed by the two countries as at December 31, 2007.
 
Our subsidiary owning interests in oil and gas properties in North West Shelf project in Australia is subject to income tax at the rate of 30%. All of our other subsidiaries had no taxable profit in their respective jurisdictions for the years presented.
 
We calculate deferred taxation to account for temporary differences between our tax bases, which is used for income tax reporting and prepared in accordance with applicable tax guidelines, and our accounting bases, which is prepared in accordance with applicable financial reporting requirements.  Major temporary differences include accelerated amortization allowances for oil and gas properties, which are offset in part by provision for dismantlement and a provision for impairment of property, plant and equipment and write-off of unsuccessful exploratory drilling.  As of December 31, 2005, 2006 and 2007, we had Rmb 6,827.9 million, Rmb 7,236.2 million and Rmb 6,293.6 million (US$862.8 million), respectively, in net deferred tax liabilities.  See note 12 to our consolidated financial statements included elsewhere in this annual report.
 
We adopted the provisions of FASB Interpretation No. 48, Accounting for Uncertainty in Income Taxes (“FIN 48”), on January 1, 2007, which prescribes a comprehensive model for how a company should recognize, measure, present and disclose in its financial statements uncertain tax positions that the company has taken or expects to take on a tax return. The adoption of FIN 48 did not have any material effect on our financial position and results of operations.
 
Impact of Recently Issued Accounting Standards
 
U.S. GAAP

In December 2007, the Financial Accounting Standards Board (“FASB”) issued SFAS No. 141 (revised 2007) “Business Combinations” (“SFAS 141 (R)”), which requires the acquiring entity in a business combination to recognize the assets acquired, the liabilities assumed, and any noncontrolling interest in the acquiree at the acquisition date to be measured at their respective fair values. It also requires acquisition-related costs, as well as restructuring costs the acquirer expects to incur for which it is not obligated at acquisition date, to be recorded against income rather than included in purchase-price determination. Under this statement, contingent arrangements shall be recognised at their acquisition-date fair values, with subsequent changes in fair value generally reflected in income. SFAS No. 141 will become effective for business combinations for which the acquisition date is on or after January 1, 2009. We are currently evaluating the potential impact of SFAS No. 141(R) on our financial position and results of operations.

In December 2007, FASB issued SFAS No. 160 “Noncontrolling Interests in Consolidated Financial Statements—an amendment of ARB No. 51”, which establishes accounting and reporting standards for the noncontrolling interest in a subsidiary and for the deconsolidation of a subsidiary. It will become effective for the accounting period beginning on or after January 1, 2009. We are currently evaluating the potential impact of SFAS No. 160 on our financial position and results of operations.

In March 2008, FASB issued SFAS No. 161 "Disclosures about Derivative Instruments and Hedging Activitiesan amendment of FASB Statement No. 133", which amends and expands the disclosure requirements of SFAS No.133, Accounting for Derivative Instruments and Hedging Activities. It requires qualitative disclosures about objectives and strategies for using derivatives, quantitative disclosures about fair value amounts of and gains and losses on derivative instruments, and disclosures about credit-risk-related contingent features in derivative agreements. It will become effective for financial statements issued for accounting period beginning on or after January 1, 2009. As our existing accounting policy for derivatives complies with the requirements of this Statement, we do not believe the adoption of SFAS No. 161 will have a material effect on our financial position or results of operations.
 
Hong Kong GAAP
 
The Hong Kong Institute of Certified Public Accountants has issued a number of new and revised HKFRSs, some of which were mandatory for financial statements for annual periods beginning on or after January 1, 2007.  We have included the new disclosures as required by HKAS 1 Amendment and HKFRS 7 and the adoption of the other new and revised Hong Kong Financial Reporting Standards, amendments and interpretation did not have a material impact on our results of operations or financial position.

The Hong Kong Institute of Certified Public Accountants has issued a number of new and revised HKFRSs that are effective for accounting periods beginning on or after January 1, 2008.  We have not early applied these HKFRSs in our consolidated financials statements included elsewhere in this annual report.  We are in the process of making an assessment of the impact of these new and revised HKFRSs upon initial application. So far, we have concluded that while certain new or revised HKFRSs may result in new or amended disclosures, these new and revised HKFRSs are unlikely to have a significant impact on our results of operations and financial position.
 
For details, please refer to note 2.1 and 2.2 to our consolidated financial statements included elsewhere in this annual report.

See “Item 4—Information on the Company—Business Overview—Research and Development” and “Item 7—Major Shareholders and Related Party Transactions—Related Party Transactions.”
 
D.
 
Crude oil prices are a major driver of our results of operations.  We price our crude oil with reference to the international crude oil prices, which have fluctuated considerably over the years.  On January 3, 2007 the international benchmark crude oil, West Texas Intermediate, was US$58.32 per barrel.  As of May 30, 2008, it was US$127.35 per barrel.  In addition, continued political conflicts in the Middle East and Nigeria, economic uncertainty and the threat of terrorism worldwide raise concerns about the security and availability of ample supplies to meet growing demand.  It is expected that crude oil prices will remain relatively high in 2008.  For more information about crude oil prices, see “Item 3—Key Information—Risk Factors—Risks relating to our business—Our business, revenues and profits fluctuate with changes in oil and gas prices,” “Item 4—Information on the Company—Business Overview—Sales and Marketing—Sales of Crude Oil—Pricing,” and “Item 5—Operating and Financial Review and Prospects—Operating Results—Results of Operations—2007 versus 2006.”
 
In addition to crude oil, natural gas is becoming an increasingly important part of our business.  The Chinese government promotes the use of natural gas as a clean and efficient fuel.  Demand for natural gas in the PRC is likely to increase significantly.  We have expanded and will continue to expand our natural gas business and intend to exploit our natural gas reserves to meet growing demand for natural gas.  For more information about our natural gas business, see “Item 3—Key Information—Risk Factors—Risks relating to our business—Any failure to implement our natural gas business strategy may adversely affect our business and financial position” and “Item 4—Information on the Company—Business Overview—Competitive Strengths—Strategic position in China’s growing natural gas markets.”

Provision for dismantlement represents the discounted present value of retirement obligations in connection with upstream assets, which primarily relate to asset removal costs at the completion date of the relevant project.

As of December 31, 2006 and 2007, we had the following capital commitments, principally for the construction and purchase of property, plant and equipment:

The maximum aggregate number of shares (including those that could be subscribed for under the Pre-Global Offering Share Option Scheme, the 2001 Share Option Scheme, the 2002 Share Option Scheme and the 2005 Share Option Scheme) which may be issued upon exercise of all options granted shall not exceed 10% of our total issued share capital as at December 31, 2005, being the date on which our shareholders approved the 2005 Share Option Scheme, excluding shares under options which have lapsed.
 
Pre-Global Offering Share Option Scheme
 
On February 4, 2001, we adopted a pre-global offering share option scheme (the “Pre-Global Offering Share Option Scheme”).  Pursuant to the Pre-Global Offering Share Option Scheme:

The exercise periods for options granted under the Pre-Global Offering Share Option Scheme shall end not later than 10 years from March 12, 2001.  No further options may be granted under the Pre-Global Offering Share Option Scheme.
 
2001 Share Option Scheme

On February 4, 2001, we adopted a share option scheme (the “2001 Share Option Scheme”) for the purposes of recognizing the contribution that certain individuals had made to our company and attracting and retaining the best available personnel to our company.  Pursuant to the 2001 Share Option Scheme:

 
1.
options to subscribe for an aggregate of 44,100,000 shares have been granted;

 
2.
the exercise price for such options is HK$1.232 per share; and

2002 Share Option Scheme

In June 2002, we adopted a new share option scheme (the “2002 Share Option Scheme”).

Under the 2002 Share Option Scheme, our Board may, at its discretion, offer to grant to the directors and employees of our company or any of our subsidiaries options to subscribe for our shares.  The maximum number of shares in respect of which options may be granted under the 2002 Share Option Scheme to any individual in any 12-month period up to the date of the latest grant shall not exceed 1% of our total issued share capital from time to time.

According to the 2002 Share Option Scheme, the consideration payable by a grantee for the grant of options will be HK$1.00.  The exercise price for such options is determined by our Board at its discretion at the date of grant, except that such price shall be not less than the higher of:

 
1.
the nominal value of a share of our company on the date of grant;

 
2.
the average closing price of the shares on HKSE as stated in HKSE’s quotation sheets for the five trading days immediately preceding the date of grant; and

 
3.
the closing price of the shares on HKSE as stated in HKSE’s quotation sheets on the date of grant.

On February 24, 2003, our Board approved to grant options in respect of 42,050,000 shares to our directors and senior management under the 2002 Share Option Scheme.  The exercise price for such options is HK$2.108 per share.  The closing market price immediately before the date on which such options were granted was HK$2.11 per share.  Such options granted under the 2002 Share Option Scheme may be exercised, in whole or in part, in accordance with the following vesting schedule:

The exercise periods for the above options granted under the 2002 Share Option Scheme shall end not later than 10 years from February 24, 2003.

On February 5, 2004, our Board approved a grant of options in respect of 50,700,000 shares to our directors and senior management under the 2002 Share Option Scheme.  The exercise price for such options is HK$3.152 per share.  The closing market price immediately before the date on which such options were granted was HK$3.146 per share.  Such options granted under the 2002 Share Option Scheme may be exercised, in whole or in part, in accordance with the following vesting schedule:

2005 Share Option Scheme

We undertook a review of the 2002 Share Option Scheme in 2005 and noted that certain provisions could be clarified and improved.  Accordingly, our Board proposed, and on December 31, 2005, we adopted a new share option scheme (the “2005 Share Option Scheme”) and terminated the 2002 Share Option Scheme.  Upon termination of the 2002 Share Option Scheme, no further options may be granted under the 2002 Share Option Scheme, but in all other respects the provisions of the 2002 Share Option Scheme shall remain in force.  The outstanding options under the 2002 Share Option Scheme shall continue to be subject to the provisions of the 2002 Share Option Scheme, and the adoption of the 2005 Share Option Scheme will not in any way affect the terms of the grant of such outstanding options.

Under the 2005 Share Option Scheme, our Board has the authority to grant options to subscribe for shares to the directors, officers and employees of our company and its subsidiaries, and any other persons who in sole discretion of our Board have contributed or will contribute to us.  Unless approved by our shareholders, the total number of shares issued and to be issued upon exercise of the options granted to each individual (including exercised and unexercised options) under the 2005 Share Option Scheme or any other share option scheme adopted by us, in any 12 months period, must not exceed 1% of our shares in issue.

According to the 2005 Share Option Scheme, the consideration payable by a grantee for the grant of options will be HK$1.00.  The exercise price for such options will be determined by our Board at its discretion at the date of grant, except that such price shall be at least the higher of:

 
1.
the nominal value of a share of our company on the date of grant;

 
2.
the average closing price of the shares as stated in HKSE’s quotation sheets for the five trading days immediately preceding the date of grant; and
 
 
 
 
3.
the closing price of the shares as stated in HKSE’s quotation sheets on the date of grant.

The period within which the options must be exercised, as well as any minimum holding period or performance targets which apply to the options, will be specified by our Board at the time of grant.  The exercise periods for options granted under the 2005 Share Option Scheme shall end not later than 10 years from the date of grant.

On June 14, 2006, our Board approved a grant of options in respect of 82,320,000 shares to our directors and senior management under the 2005 Share Option Scheme. The exercise price for such options is HK$5.56 per share. The closing market price immediately before the date on which such options were granted was HK$5.30 per share.  Such options granted under the 2005 Share Option Scheme may be exercised, in whole or in part, in accordance with the following vesting schedule:

CNOOC owns our shares indirectly through its wholly owned subsidiaries, CNOOC (BVI) Limited and Overseas Oil & Gas Corporation, Ltd.  CNOOC’s share ownership decreased from 64.95% as of December 31, 2007 to 64.41% as of May 30, 2008 due to an increase in our total outstanding shares as a result of the conversion of bonds and the exercise of options.

 
 
Our major shareholder listed above does not have voting rights different from our other shareholders.  Except as set forth in the above table, we are not aware of any shareholders that hold more than 5% of our shares.  Except as disclosed above, we are not aware of any significant changes in the percentage ownership of our major shareholder over the course of the past three years.  To our knowledge, no arrangements are currently in place that could lead to a change of control of our company.
 
As of May 30, 2008, 11,651,950 American depositary shares were outstanding in the United States, representing approximately 2.61% of our then outstanding shares.  At such date, the number of registered American depositary share holders in the United States was 28.

Overview
 
We regularly enter into transactions with related parties, including CNOOC and its associates, as defined under the Hong Kong Stock Exchange Listing Rules.  Since CNOOC indirectly owns an aggregate of approximately 64.41% of our issued share capital, some of these transactions constitute connected transactions under the Hong Kong Stock Exchange Listing Rules, and are regulated by the Hong Kong Stock Exchange.
 
Under the Hong Kong Stock Exchange Listing Rules, many of these connected transactions normally would require full disclosure and the prior approval of our independent shareholders.  However, since the connected transactions are carried out in the ordinary and usual course of business and occur on a regular basis on normal commercial terms and on terms that are fair and reasonable as far as our shareholders are concerned, the Hong Kong Stock Exchange granted us a waiver from strict compliance with requirements of the Hong Kong Stock Exchange Listing Rules for the period from April 3, 2001 through December 31, 2002, after which this waiver was renewed to cover the period from January 1, 2003 to December 31, 2005.  Following the amendments to the Hong Kong Stock Exchange Listing Rules in March 2004, waivers for connected transactions from the Hong Kong Stock Exchange are no longer required, and we are only required to obtain our independent shareholders’ approval for such continuing connected transactions.  Accordingly, we obtained independent shareholders’ approval at the extraordinary general meetings held on December 31, 2005 and on December 6, 2007 for our continuing connected transactions with CNOOC and/or its associates for the period from January 1, 2006 to December 31, 2007 and for the period from January 1, 2008 to December 31, 2010, respectively.  The continuing connected transactions are categorized into different categories, and each category of connected transactions is subject to annual caps and other conditions as specified below.

New Categories of Continuing Connected Transactions

In order to present a more coherent, logical and understandable picture to shareholders, and also to enable our company to monitor the status of connected transactions as defined under the Hong Kong Stock Exchange Listing Rules more effectively going forward, we adopted a new categorization for our continuing connected transactions with CNOOC and/or its associates.  On December 8, 2005, we entered into three comprehensive framework agreements with each of CNOOC, COSL and CNOOC Engineering, respectively for the provision (1) by us to CNOOC and/or its associates and (2) by CNOOC and/or its associates to us, of a range of products and services which may be required and requested from time to time by either party and/or its associates in respect of the new categories of continuing connected transactions.  The term of each of the comprehensive framework agreements is for a period of two years from January 1, 2006.  The new categorization and caps for each category of continuing connected transactions were approved by our independent shareholders on December 31, 2005 and are applicable for the period from January 1, 2006 to December 31, 2007.  On September 29, 2006, we further obtained independent shareholders’ approval for the revised cap for the category “sales of petroleum and natural gas products” by us to CNOOC and/or its associates.  The new categorization of continuing connected transactions, which are discloseable under the Hong Kong Stock Exchange Listing Rules and applicable to our company for the period from January 1, 2006 to December 31, 2007, are set out below:
 
 
 
 
·
Provision of exploration, oil and gas development, oil and gas production as well as marketing, management and ancillary services by CNOOC and/or its associates to us;

CNOOC also provides certain of these services from time to time.  The services provided by CNOOC and/or its associates are set out below.

Pricing principles for transactions referred to in paragraphs (a) to (d) above:

The continuing connected transactions referred to in paragraphs (a) to (d) above relate to services provided by CNOOC and/or its associates to us. In general, the services provided by CNOOC and/or its associates to us are based on negotiations with CNOOC and/or its associates on normal commercial terms, or on terms no less favourable than those available to us from independent third parties, under prevailing local market conditions, including considerations such as volume of sales, length of contracts, package of services, overall customer relationship and other market factors.
 
 
 
 
If, for any reason, the above pricing principle for a particular service ceases to be applicable or there is no open market for such services, whether due to a change in circumstances or otherwise, such services must then be provided in accordance with the following general pricing principles:

(i)    state-prescribed prices; or

(ii)   where there is no state-prescribed price, market prices, including the local, national or international market prices; or

(iii)  when neither (i) nor (ii) is applicable, the cost to CNOOC and/or its associates for providing the relevant services (including the cost of sourcing or purchasing from third parties) plus a margin of not more than 10%, before any applicable taxes.

(e)        FPSO vessel leases.  We lease FPSO vessels from COBGL for use in oil production operations at market prices on normal commercial terms which are calculated on a daily basis.  FPSO vessels are usually located next to the offshore oil platforms and are an integrated facility used by us during the offshore oil production for processing, storage and offloading of crude oil. The terms of FPSO vessel leases are usually determined based on the expected term of oil production.

Provision of management, technical, facilities and ancillary services, including the supply of materials from us to CNOOC and/or its associates

In addition to providing various services to us, CNOOC and/or its associates may also utilise various types of management, facilities, technical and ancillary services, including the supply of materials provided by us from time to time. The pricing for such services will be determined based on the same pricing principles applicable to transactions relating to services provided by CNOOC and/or its associates to us under paragraphs (a) and (d) above, which will be negotiated and agreed on normal commercial terms between the parties. The services that may be provided by us to CNOOC and/or its associates include:

·        technical consulting;
·        technology transfer;
·        management;
·        technical research services; and
·        other supporting services.

Sales of petroleum and natural gas products by us to CNOOC and/or its associates

(a)        Sales of petroleum and natural gas products.  We may sell petroleum and natural gas products, including crude oil, condensate oil, liquefied petroleum gas, natural gas and liquefied natural gas, to CNOOC and/or its associates which engage in downstream petroleum businesses at state-prescribed prices or local, national or international market prices and on normal commercial terms. It is envisaged that an individual sales contract will be entered into from time to time between us and CNOOC and/or its associates in relation to such sales.
 
 
 
(b)        Long term sales of natural gas and liquefied natural gas.  We sell natural gas to CNOOC and/or its associates which engage in downstream petroleum businesses at state-prescribed prices or local, national or international market prices and on normal commercial terms, which is subject to adjustment in accordance with movements in international oil prices as well as other factors such as the term of the sales agreement and length of the relevant pipelines. Due to the size of investment and the fact that sales are usually made to markets proximate to the production sites, and that purchasers tend to utilise the natural gas products in areas close to the production sites, and in order to ensure the return on the investment from the production of natural gas, we will usually enter into long term sales contracts with a term of 15 to 20 years. It is market practice for the term of the sales contract to be determined based on the estimated reserves and production profile of the relevant gas fields.  We have also invested and acquired interests in liquefied natural gas related upstream projects in Tangguh of Indonesia and the North West Shelf of Australia.  It is also envisaged that from time to time we may sell liquefied natural gas explored from these gas reserves mentioned above and other gas reserves in which we may invest in the future to CNOOC and/or its associates.
 
Disclosure and/or Independent Shareholders’ approval requirements
 
Under the Hong Kong Stock Exchange Listing Rules, the following categories amongst the new categories of continuing connected transactions are exempted from the independent shareholders’ approval requirement but are subject to the reporting and announcement requirements set out in Rules 14A.45 to 14A.47 of the Hong Kong Stock Exchange Listing Rules, because the percentage ratios for these categories under the Listing Rules (other than the profits ratio) are expected to be less than 2.5% on an annual basis:

Transactions with CNOOC Finance Corporation Limited
 
In addition to the above related party transactions, we also entered into a framework agreement (the “Framework Agreement”) with CNOOC Finance Corporation Limited (“CNOOC Finance”) on April 8, 2004. Under the Framework Agreement, we utilized the financial services provided by CNOOC Finance, our 31.8% owned associate and a subsidiary of CNOOC. Such services include placing of our cash deposits with CNOOC Finance, settlement services for transactions between us and other entities including CNOOC and its associates and the provision of loans. The charges including the interest rates and other fees levied by CNOOC Finance for the financial services provided to us are based on the pricing policies of CNOOC Finance, which are subject to the pricing guidelines of the People’s Bank of China , as well as the guidelines published by the China Banking Regulatory Committee.  Based on these guidelines, CNOOC Finance has limited discretion in setting its prices.

As the waiver for the deposit services provided by CNOOC Finance to us with the cap of Rmb 6.8 billion, which expired on April 7, 2007, was not renewed, we have only continued to use the financial services provided by CNOOC Finance to the extent that they are exempted from the reporting, announcement and independent shareholders’ approval requirements under the Hong Kong Stock Exchange Listing Rules.
 
 
 
 
For the years ended December 31, 2005 and 2006 and 2007, the maximum outstanding balance of deposits (including interest received in respect of these deposits) placed with CNOOC Finance Corporation Limited amounted to approximately Rmb 3.9 billion, Rmb 6.4 billion and Rmb 6.5 billion (US$891.3 million), respectively.

ITEM 8.  FINANCIAL INFORMATION
 
A.
 
See pages beginning on page F-1 following Item 19.
 
Legal Proceedings
 
We are not a defendant in any material litigation, claim or arbitration, and we know of no pending or threatened proceeding which would have a material adverse effect on our financial condition.
 
Dividend Distribution Policy
 
The payment of any future dividends will be determined by our Board, subject to shareholders’ approval for all dividends other than interim dividends, based upon, among other things, our future earnings, capital requirements, financial conditions, future prospects and other factors which our Board may consider relevant. Our ability to pay dividends will also depend on the cash flows determined by the dividends, if any, received by us from our subsidiaries and associates.  Holders of our shares will be entitled to receive such dividends declared by our Board pro rata according to the amounts paid up or credited as paid up on the shares.  Subject to the factors described above, we currently intend to pursue a dividend policy consistent with other international oil and gas exploration and production companies.
 
Dividends may be paid only out of our distributable profits as permitted under Hong Kong law, which does not restrict the payment of dividends to nonresident holders of our securities.  To the extent profits are distributed as dividends, such portion of profits will not be available to be reinvested in our operations.
 
Holders of our ADSs will be entitled to receive dividends, subject to the terms of the deposit agreement, to the same extent as holders of our shares, less the fees and expenses payable under the deposit agreement.  Cash dividends will be paid to the depositary in Hong Kong dollars and will be converted by the depositary into U.S. dollars and paid to holders of ADSs. Stock dividends, if any, will be distributed to the depositary and will be distributed by the depositary, in the form of additional ADSs, to holders of the ADSs.
 
In 2005, we declared and paid dividends totaling Rmb 7,772.2 million.  In 2006, we declared and paid dividends totaling Rmb 9,813.7 million.  In 2007, we declared and paid dividends totaling Rmb 11,523.7 million (US$1,579.8 million).  The amount of dividends we paid historically is not indicative of the dividends that we will pay in the future.

Substantially all our dividend payments result from dividends paid to us by CNOOC China Limited.  CNOOC China Limited must follow the laws and regulations of the PRC and its articles of association in determining its dividends.  As a wholly foreign owned enterprise in China, CNOOC China has to provide for a reserve fund and staff and workers’ bonus and welfare fund, each of which is appropriated from net profit after taxation but before dividend distribution according to the prevailing accounting rules and regulations in the PRC.  CNOOC China Limited is required to allocate at least 10% of its net profit to the reserve fund until the balance of this fund has reached 50% of its registered capital, which amount was reached in 2007.  Appropriations to the staff and workers’ bonus and welfare fund, which are determined at the discretion of the directors of CNOOC China Limited, are charged to expense as incurred in our consolidated financial statements, which were prepared under Hong Kong GAAP.  None of the contributions of CNOOC China Limited to these statutory funds may be used for dividend purposes.
 
For the years ended December 31, 2005, 2006 and 2007, CNOOC China Limited made the following appropriations to the statutory reserves:

During the first quarter of 2008, our unaudited revenues from the sale of oil and gas were Rmb 23.8 billion.  Our daily average crude oil production was 392,722 barrels per day during this period, compared to 378,734 barrels per day in 2007, while our daily average natural gas production was 601 million cubic feet per day, compared to 550 million cubic feet per day in 2007.  The average net realized price of our crude oil was US$88.76 per barrel during the first quarter of 2008, compared to US$52.45 per barrel in 2007, while the average net realized price of our natural gas was US$3.65 per thousand cubic feet, compared to US$3.19 per thousand cubic feet in 2007.
 

ITEM 9.  THE OFFER AND LISTING
 
Not applicable, except for Item 9.A.4 and Item 9.C.
 
We listed our shares on the Hong Kong Stock Exchange and our ADSs on the New York Stock Exchange in February 2001.  Our shares are listed on the Hong Kong Stock Exchange under the stock code “883” and our ADSs are listed on the New York Stock Exchange under the symbol “CEO.”  On March 17, 2004, our shareholders approved a five-for-one stock split of our shares.  The stock split was effected by dividing each of our issued and unissued shares of HK$0.10 each into five shares of HK$0.02 each.  The ratio of our American depositary shares listed on the New York Stock Exchange also changed such that each ADS now represents 100 subdivided shares of HK$0.02 each, as opposed to 20 shares of HK$0.10 each prior to the stock split.  The following table sets forth, for the periods indicated, the high and low closing prices per share, as reported on the Hong Kong Stock Exchange and adjusted retroactively to reflect the stock split, and per ADS, as reported on the New York Stock Exchange.

ITEM 10.  ADDITIONAL INFORMATION
 
A.
 
Not applicable.
 
B.
 
We were incorporated with limited liability on August 20, 1999 in Hong Kong under the Companies Ordinance (Chapter 32 of the Laws of Hong Kong) (the “Hong Kong Companies Ordinance”).  Our company registration number in Hong Kong is 685974.  Under section three of our memorandum of association, we have the capacity and the rights, powers and privileges of a natural person and we may also do anything which we are permitted or required to do by any enactment or rule of law.  The following are summaries of provisions of our memorandum and articles of association and the Hong Kong Companies Ordinance.  For further details, you should read our memorandum of association, which was filed as an exhibit to our registration statement on Form F-1 (Registration No.333-10862) and our articles of association, as amended, which was filed as an exhibit to our annual report on Form 20-F for the fiscal year of 2005.
 
Issue of Shares
 
Under the Hong Kong Companies Ordinance our directors may, without obtaining the prior approval of our shareholders, offer to allot new shares in our company to existing shareholders on a pro rata basis.  Our directors may not allot new shares of our company in any other manner without the prior approval of our shareholders at a general meeting.  Any approval given at a general meeting granting our directors power to allot shares or securities convertible into shares generally shall continue in force from the date of the passing of the resolution until the earliest of:

·  
the conclusion of the next annual general meeting;

·  
the expiration of the period within which the next annual general meeting is required by any applicable laws or our articles of association to be held; or

·  
the revocation or variation of the authority given under an ordinary resolution of the shareholders, in a general meeting of our company.
 
 
 
If such an approval for a general mandate to issue shares is given, the unissued shares of our company shall be at the disposal of our Board.  Our directors may offer, allot, grant options over or otherwise dispose of the unissued shares to persons at such times and for such consideration and upon such terms and conditions as our directors may determine, subject to the restrictions under the Hong Kong Stock Exchange Listing Rules.

In accordance with Hong Kong Stock Exchange Listing Rules, any such approval of the shareholders must be limited to shares not exceeding 20% of our share capital in issue as of the date of granting such approval plus the share capital repurchased by us since the granting of such approval.
 
Dividends
 
Subject to the Hong Kong Companies Ordinance, the shareholders at a general meeting may declare dividends to be paid to shareholders.  However, under our articles of association, dividends cannot be declared in excess of the amount recommended by our Board.

In addition to dividends declared at a general meeting, our Board may declare and pay to the shareholders interim dividends as our Board deems justified by our financial position.  Our Board may also pay any fixed dividend on any shares of our company semi-annually or at other suitable intervals, whenever our financial position, in their opinion, justifies such payment.
 
Winding Up
 
If we are wound up, the surplus assets remaining after payment to all creditors are to be divided among our shareholders in proportion to the capital paid up on the shares held by them respectively, and if such surplus assets are insufficient to repay the whole of the paid-up capital, they are to be distributed so that the losses are borne by our shareholders in proportion to the capital paid up on the shares held by them respectively.  The liquidator may, with the sanction of a special resolution, divide among our shareholders in specie or in kind the whole or any part of our assets or vest any part of our assets in trustees upon such trusts for the benefit of our shareholders or any of them as the resolution shall provide.
 
Voting Rights
 
Under the Hong Kong Companies Ordinance, any action to be taken by the shareholders at a general meeting requires the affirmative vote of either an ordinary or a special resolution passed at such meeting.

·  
An ordinary resolution is a resolution passed by the majority of shareholders that are entitled to, and do, vote in person or by proxy at a general meeting;

·  
A special resolution is a resolution passed by not less than 75% of shareholders that are entitled to, and do, vote in person or by proxy at a general meeting.

Generally, resolutions of shareholders are passed by ordinary resolution.  However, the Hong Kong Companies Ordinance provides that certain specified matters may only approved by shareholders by way of special resolutions.  These matters include, for example:

·  
alteration of the object clause;

·  
alteration of the articles;

·  
change of a company’s name;

·  
reduction of share capital; and
 
·  
voluntary winding up.
 
 
 
Subject to the requirement of the Hong Kong Stock Exchange Listing Rules, voting at any general meeting is by a show of hands unless a poll is demanded.  If voting is by a show of hands, every shareholder who is present at the meeting in person or by proxy has one vote.  On a poll, every shareholder who is present in person or by proxy has one vote for every share held or represented by him.  A poll may be demanded by:

·  
the chairman of the meeting;

·  
at least three members present in person (or in the case of a member being a corporation, by its duly authorized representative) or by proxy and entitled to vote at the meeting;

·  
any member or members present in person (or in the case of a member being a corporation, by its duly authorized representative) or by proxy and representing in the aggregate not less than 10% of the total voting rights of all members having the right to attend and vote at the meeting; or

·  
any member or members present in person (or in the case of a member being a corporation, by its duly authorized representative) or by proxy and holding shares conferring a right to attend and vote at the meeting on which there have been paid up sums in the aggregate equal to not less than 10% of the total sum paid up on all shares conferring that right.

Any action to be taken by the shareholders requires the affirmative vote of the requisite majority of the shares at a general meeting.  There are no cumulative voting rights.  Accordingly, the holders of a majority of the shares voting for the election of directors can elect all the directors if they choose to do so.

Under Hong Kong law and our memorandum and articles of association, shareholders who are not residents of Hong Kong may hold, vote and transfer their shares in our company in the same manner as our shareholders who are Hong Kong residents.
 
General Meetings
 
We are required to hold an annual general meeting each year within fifteen months from the date of our last annual general meeting.  We may also hold extraordinary general meetings from time to time.  Our Board may convene an extraordinary general meeting at will, and shall on requisition in accordance with the Hong Kong Companies Ordinance, proceed to convene an extraordinary general meeting.  Our annual general meeting and a meeting called for the purpose of passing a special resolution require at least twenty-one days’ prior notice, and any other general meeting requires at least fourteen days’ prior notice.  The notice must specify the place, day and time of the meeting and, in the case of special business, the general nature of that business.  The quorum for a general meeting is two shareholders present in person or by proxy.  If within thirty minutes from the time appointed for the meeting a quorum is not present, the meeting, if convened upon requisition in accordance with the Hong Kong Companies Ordinance, must be dissolved; but in any other case it must stand adjourned to the same day in the next week at the same time and place, or to such other day, time and place as the chairman of the meeting may determine.  If at such adjourned meeting a quorum is not present within thirty minutes from the time appointed for the meeting, the member or members present in person or by proxy shall be a quorum and may transact the business for which the meeting is called.
 
At each annual general meeting one third of our directors are to retire from office by rotation, save any director holding office as chairman or chief executive officer.  The directors to retire every year are to be those who have been longest in office since their last election and the retiring directors will be eligible for re-election.
 
 
 
Modification of Rights
 
Subject to the Hong Kong Companies Ordinance, any of the rights attaching to any class of shares, unless otherwise provided for by the terms of issue of the shares of that class, may be varied or abrogated with the written consent of the holders of not less than 75% of the issued shares of that class or with the sanction of a special resolution passed at a separate general meeting of the holders of shares of that class.
 
Borrowing Powers
 
Our Board may exercise all the powers of our company to borrow money and to mortgage or charge all or any part of our undertaking, property and assets, whether present or future, and uncalled capital.  Our Board may issue debentures, debenture stock, bonds or other securities of our company, whether outright or as collateral security for any debt, liability or obligation of our company or of any third party.  These borrowing powers are subject to variation by a special resolution of our company.
 
Interested Transactions
 
Subject to the exceptions described below, none of our directors may vote on any contract, arrangement or proposal in which the director or any of his or her associates is materially interested.  For this purpose,  existence of material interest is presumed if a company, in which the director and/or his or her associates beneficially own 5% or more of any class of its shares or voting rights, is materially interested in the transaction.  Our directors may, however, vote on the following matters:
 
·  
any contract or arrangement to give security or indemnity to the director or his or her associates for money lent or obligations undertaken by such director or his or her associates at the request of or for the benefit of our company or subsidiaries;
 
·  
any contract or arrangement to give security or indemnity to a third party for our debts or debts of our subsidiaries for which such director or his or her associates assumed responsibility by giving guarantee or security;
 
·  
any contract or arrangement concerning offering of securities by us (or any company which we may promote or be interested in purchasing) for which the director or his or her associates participate in the underwriting or sub-underwriting;
 
·  
any contract or arrangement in which the director or his or her associates are interested only by virtue of their interest in our securities;
 
·  
any contract or arrangement concerning any other company in which the director or his or her associates are interested as an officer or executive or a shareholder in which the director or his or her associates are beneficially interested in shares of that company other than a company in which they in aggregate beneficially own more than 5% of the issued shares of any class or voting rights;
 
·  
any proposal or arrangement concerning employee benefits that do not provide privileges to our directors or their associates not generally accorded to the class of persons to whom such scheme or fund relates, including pension fund or retirement, death or disability benefits schemes; and
 
·  
any proposal or arrangement concerning the adoption, modification or operation of any employees’ share scheme involving the issue or grant of options over shares or other securities by us to, or for the benefit of, our employees or employees of our subsidiaries under which the director or his or her associates may benefit.
 
 
 
C.
 
We have not entered into any material contracts in the last two years other than in the ordinary course of business and other than those described in “Item 7―Major Shareholders and Related Party Transactions―Related Party Transactions.”
 
D.
 
For information on foreign exchange controls in the PRC, foreign exchange rates, hedging activities and related foreign exchange risks, see “Item 3—Key Information—Selected Financial Data,” “Item 3—Key Information—Risk Factors—Risks relating to the PRC—Government control of currency conversion and future movements in exchange rates may adversely affect our operations and financial condition” and “Item 11—Qualitative and Quantitative Disclosure about Market Risk.”
 
E.
 
The taxation of income and capital gains of holders of our shares or ADSs is subject to the laws and practices of Hong Kong and of jurisdictions in which holders of our shares or ADSs are resident or otherwise subject to tax.  The following is a summary of taxation provisions that are anticipated to be material based on current law and practice.  This summary is subject to change and does not constitute legal or tax advice.  The discussion does not deal with all possible tax consequences relating to an investment in our shares or ADSs.  In particular, the discussion does not address the tax consequences under state, local or other laws, such as non-Hong Kong or non-U.S. federal laws.  Accordingly, we urge you to consult your tax adviser regarding the tax consequences of an investment in our shares and ADSs.  The discussion is based upon laws and relevant interpretations in effect as of the date of this annual report, all of which are subject to changes.  There is no reciprocal tax treaty in effect between Hong Kong and the United States.
 
Hong Kong
 
Tax on Dividends
 
Under the current practices of the Hong Kong Inland Revenue Department, no tax is payable in Hong Kong in connection with dividends paid by us.
 
Profits Tax
 
No tax is imposed in Hong Kong in respect of capital gains from the sale of property, such as the shares and ADSs.  Trading gains from the sale of property by persons carrying on a trade, profession or business in Hong Kong where such gains are derived from or arise in Hong Kong from such trade, profession or business will be chargeable to Hong Kong profits tax which is currently imposed at the rate of 17.5% on corporations and at a maximum rate of 16% on individuals.  Gains from sales of the shares effected on the Hong Kong Stock Exchange will be considered to be derived from or arise in Hong Kong.  Liability for Hong Kong profits tax would thus arise in respect of trading gains from sales of shares or ADSs realized by persons carrying on a business of trading or dealing in securities in Hong Kong.
 
Stamp Duty
 
Hong Kong stamp duty, currently charged at the rate of HK$1.00 per HK$1,000 or part thereof on the higher of the consideration for or the value of the shares, will be payable by the purchaser on every purchase and by the seller on every sale of shares.  A total of HK$2.00 per HK$1,000 or part thereof is currently payable on a typical sale and purchase transaction involving shares.  In addition, a fixed duty of HK$5 is currently payable on any instrument of transfer of shares.  The withdrawal of shares upon the surrender of ADRs, and the issuance of ADRs upon the deposit of shares, will also attract stamp duty at the rate described above for sale and purchase transactions unless the withdrawal or deposit does not result in a change in the beneficial ownership of the shares under Hong Kong law.  The issuance of the ADRs upon the deposit of shares issued directly to the depositary or for the account of the depositary does not incur stamp duty.  No Hong Kong stamp duty is payable upon the transfer of ADSs outside Hong Kong.
 
 
 
Estate Duty
 
The shares are Hong Kong property under Hong Kong law, and accordingly such shares may be subject to estate duty on the death of the beneficial owner of such shares, regardless of the owner’s residence, citizenship or domicile.  We cannot assure that the Hong Kong Inland Revenue Department will not treat the ADRs as Hong Kong property that may be subject to estate duty on the death of the beneficial owner of the ADR even if the ADRs are located outside Hong Kong at the date of such death.  Hong Kong estate duty is imposed on a progressive scale from 5% to 15%.  The rate of and the threshold for estate duty has, in the past, been adjusted on a fairly regular basis.  No estate duty is payable when the aggregate value of the dutiable estate does not exceed HK$7.5 million, and a maximum rate of duty of 15% applies when the aggregate value of the dutiable estate exceeds HK$10.5 million.  The Hong Kong Government is considering abolishing estate duty in Hong Kong.
 
United States

U.S. Federal Income Tax Considerations
 
The following is a discussion of the material U.S. federal income tax consequences of owning and disposing of ADSs or shares by U.S. Holders (as defined below), but it does not purport to be a comprehensive description of all the tax considerations that may be relevant to a particular person’s decision to hold such ADSs or shares.  This discussion does not address U.S. state, local and non-U.S. tax consequences.  The discussion applies only to U.S. Holders who hold ADSs or shares as capital assets for U.S. federal income tax purposes and it does not address special classes of holders, such as:
 
·  
certain financial institutions;
·  
insurance companies;
·  
dealers and traders in securities or foreign currencies;
·  
persons holding ADSs or shares as part of a hedge, straddle, conversion, integrated transaction or similar transaction;
·  
persons whose functional currency for U.S. federal income tax purposes is not the U.S. dollar;
·  
partnerships or other entities classified as partnerships for U.S. federal income tax purposes;
·  
persons liable for the alternative minimum tax;
·  
tax-exempt organizations; or
·  
persons holding ADSs or shares that own or are deemed to own 10% or more of our voting stock.
 
This discussion is based on the Internal Revenue Code of 1986, as amended, administrative pronouncements, judicial decisions and final, temporary and proposed U.S. Treasury regulations, all as of the date hereof.  These laws are subject to change, possibly on a retroactive basis.  U.S. Holders should consult their own tax advisors concerning the U.S. federal, state, local and non-U.S. tax consequences of purchasing, owning and disposing of ADSs or shares in their particular circumstances.
 
As used herein, a U.S. Holder is a beneficial owner of ADSs or shares that is, for U.S. federal income tax purposes: (i) a citizen or resident of the United States; (ii) a corporation, or other entity taxable as a corporation, created or organized in or under the laws of the United States or any political subdivision thereof; or (iii) an estate or trust the income of which is subject to U.S. federal income taxation regardless of its source.
 
In general, if you hold ADSs, you will be treated as the holder of the underlying shares represented by those ADSs for U.S. federal income tax purposes.  Accordingly, no gain or loss will be recognized if you exchange ADSs for the underlying shares represented by those ADSs.
 
 
The U.S. Treasury has expressed concerns that parties to whom American Depositary Receipts are released before delivery of shares to the depositary (“pre-release”) may be taking actions that are inconsistent with the claiming of foreign tax credits for United States holders of American Depositary Receipts.  Such actions would also be inconsistent with the claiming of the reduced rate of tax, described below, applicable to dividends received by certain non-corporate holders.  Accordingly, the availability of the reduced tax rate for dividends received by certain non-corporate holders, described below, could be affected by actions taken by parties to whom the ADSs are pre-released.
 
This discussion assumes that we were not, and will not become, a passive foreign investment company (“PFIC”), as described below.
 
Taxation of Distributions
 
Distributions received by a U.S. Holder on ADSs or shares, other than certain pro rata distributions of common shares to all shareholders, will constitute foreign source dividend income to the extent paid out of our current or accumulated earnings and profits (as determined for U.S. federal income tax purposes).  Because we do not maintain calculations of our earnings and profits under U.S. federal income tax principles, it is expected that distributions generally will be reported to U.S. Holders as dividends.  The amount of the dividend a U.S. Holder will be required to include in income will equal the U.S. dollar value of the Hong Kong dollar distribution, calculated by reference to the exchange rate in effect on the date the payment is received by the depositary (or, in the case of shares, received by the holder), regardless of whether the payment is converted into U.S. dollars on the date of receipt.  If the dividend is converted into U.S. dollars on the date of receipt, a U.S. Holder will not be required to recognize foreign currency gain or loss in respect of the dividend income.  A U.S. Holder may have foreign currency gain or loss if the dividend is converted into U.S. dollars after the date of receipt.  Corporate U.S. Holders will not be entitled to claim the dividends-received deduction with respect to dividends paid by us.
 
Subject to applicable limitations and the discussion above regarding concerns expressed by the U.S. Treasury, certain dividends paid by “qualified foreign corporations” to certain non-corporate U.S. Holders in taxable years beginning before January 1, 2011, are taxable at a maximum rate of 15%.  A foreign corporation is treated as a qualified foreign corporation with respect to dividends paid on stock that is readily tradable on an established securities market in the United States, such as the New York Stock Exchange where our ADSs are traded. Non-corporate U.S. Holders should consult their own tax advisers to determine whether these favorable rates may apply to dividends they receive from us and whether they are subject to any special rules that limit their ability to be taxed at this favorable rate.
 
Sale or Other Disposition of ADSs or Shares
 
A U.S. Holder will generally recognize capital gain or loss on the sale or other disposition of ADSs or shares, which will be long-term capital gain or loss if the holder has held such ADSs or shares for more than one year.  The amount of the U.S. Holder’s gain or loss will be equal to the difference between the amount realized on the sale or other disposition (as determined in U.S. dollars) and such holder’s tax basis in the ADSs or shares (as determined in U.S. dollars).  Any gain or loss will generally be U.S. source gain or loss for foreign tax credit purposes.
 
Passive Foreign Investment Company Considerations
 
We believe that we were not a PFIC for U.S. federal income tax purposes for our taxable year ended December 31, 2007.  In general, a non-U.S. company will be considered a PFIC for U.S. federal income tax purposes for any taxable year in which (i) 75% or more of its gross income consists of passive income (such as dividends, interest, rents and royalties) or (ii) 50% or more of the average quarterly value of its assets consists of assets that produce, or are held for the production of, passive income.  As PFIC status depends upon the composition of our income and assets and the market value of our assets (including, among other things, any equity investments in less than 25%-owned entities) from time to time, and since there are uncertainties in the manner of application of the PFIC rules, there can be no assurance that we will not be considered a PFIC for any taxable year.
 
 
 
If we were to be treated as a PFIC for any taxable year during which a U.S. Holder held ADSs or shares, certain adverse U.S. federal income tax rules would apply on a disposition (including a pledge) of ADSs or shares by the U.S. Holder.  In general, under those rules, gain recognized by the U.S. Holder on a sale or other disposition of ADSs or shares would be allocated ratably over the U.S. Holder’s holding period for the ADSs or shares.  The amounts allocated to the taxable year of the sale or other disposition and to any year before we became a PFIC would be taxed as ordinary income.  The amount allocated to each other taxable year would be subject to tax at the highest rate in effect for individuals or corporations, as appropriate, for such taxable year, and an interest charge would be imposed on the amount allocated to each such taxable year.  Further, any distribution in respect of ADSs or shares in excess of 125% of the average of the annual distributions on ADSs or shares received by the U.S. Holder during the preceding three years or the U.S. Holder’s holding period, whichever is shorter, would be subject to taxation as described above.  Certain elections may be available (including a mark-to-market election) to U.S. Holders that may mitigate the adverse tax consequences resulting from PFIC status.
 
In addition, if we were to be treated as a PFIC in a taxable year in which we pay a dividend or the prior taxable year, the 15% dividend rate discussed above with respect to dividends received by certain non-corporate U.S. Holders would not apply.
 
Information Reporting and Backup Withholding
 
Payment of dividends and sales proceeds that are made within the United States or through certain U.S.-related financial intermediaries generally are subject to information reporting and to backup withholding unless the U.S. Holder is a corporation or other exempt recipient or, in the case of backup withholding, the U.S. Holder provides a correct taxpayer identification number and certifies that no loss of exemption from backup withholding has occurred. The amount of any backup withholding from a payment to a U.S. Holder will be allowed as a credit against the holder’s U.S. federal income tax liability and may entitle such holder to a refund, provided that the required information is furnished to the Internal Revenue Service.

ITEM 11.  QUALITATIVE AND QUANTITATIVE DISCLOSURES ABOUT MARKET RISK
 
Our market risk exposures primarily consist of fluctuations in oil and gas prices, exchange rates and interest rates.
 
Commodity Price Risks

We are exposed to fluctuations in prices of crude oil.  International oil prices are volatile and this volatility has a significant effect on our net sales and profit. We do not hedge market risk resulting from fluctuations in oil prices. See “Item 4—Information on the Company—Business Overview—Overview” and “Item 3—Key Information—Risk Factors—Risks relating to our business—Our business, revenues and profits fluctuate with changes in oil and gas prices.”
 
Currency Risk

Our foreign exchange exposure gives rise to market risk associated with exchange rate movements.
 
Substantially all of our oil and gas sales are denominated in Renminbi and U.S. dollars.  In the last ten years, the PRC government’s policy of maintaining a stable exchange rate and China’s ample foreign reserves have contributed to the stability of the Renminbi.  On July 21, 2005, China reformed its foreign exchange regime by moving into a managed floating exchange rate system based on market supply and demand with reference to a basket of currencies.  The Renminbi is no longer pegged to the U.S. dollar.  From that day to May 30, 2008, the Renminbi appreciated approximately 19.1% against the U.S. dollar.  However, the Chinese government has not yet determined if or when the exchange rate will be deregulated.
 
Our management has assessed our exposure to foreign currency risk using a sensitivity analysis.  Based on a five percent change in the value of the U.S. dollar occurring on December 31, 2007, the exposure of our results of operations, monetary assets and liabilities and investments in foreign subsidiaries would each be less than 0.1% of our profit for the year.
 
The appreciation of the Renminbi against the U.S. dollar may have the following impact on us:
 
·  
Our oil and gas sales may decrease, because the benchmark oil and gas prices are usually in U.S. dollars;
 
·  
Our cost for imported equipment and materials will decrease, because most of these costs are denominated in U.S. dollars; and
 
·  
Our debt repayment burden will decrease, since approximately 96% of our debt is denominated in U.S. dollars.
 
For further information on our currency risk, see “Item 3—Key Information—Risk Factors—Risks relating to the PRC— Government control of currency conversion and future movements in exchange rates may adversely affect our operations and financial condition.”
 
Interest Rate Risk

We are exposed to interest rate risk arising from our loans.  An upward fluctuation in interest rates increases the cost of new debt and the cost of servicing our floating rate debt.  We may use interest rate swap transactions, from time to time, to hedge our interest rate exposure when considered appropriate, based on existing and anticipated market conditions.
 
As of December 31, 2007, the interest rates for 78% of our outstanding debts were fixed.  The term of the weighted average balance was approximately 8.5 years.  A fixed interest rate can reduce the volatility of finance costs and is considered to be favorable in an environment of rising interest rates. We do not currently engage in any interest rate hedging activities.

ITEM 15.  CONTROLS AND PROCEDURES
 
(a)    Disclosure Controls and Procedures
 
An evaluation was carried out under the supervision and with the participation of management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness, as of December 31, 2007, of the design and operation of our disclosure controls and procedures (as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)).
 
Based upon this evaluation, our Chief Executive Officer and Chief Financial Officer concluded that, as of December 31, 2007, our disclosure controls and procedures were effective to ensure that information required to be disclosed by us in our reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported as and when required by the SEC’s rules and forms and is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.
 
 (b)    Management’s annual report on internal control over financial reporting
 
Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as defined in Rule 13a-15(f) under the Exchange Act.
 
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. 
 
 
 
Our management assessed the effectiveness of our internal control over financial reporting as of December 31, 2007 using the criteria set forth in Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on this assessment, our management has concluded that our internal control over financial reporting as of December 31, 2007 was effective.
 
 (c)    Attestation Report of the Registered Public Accounting Firm
 
Our independent auditors have issued an audit report on the effectiveness of our internal control over financial reporting. This report appears on page F-4.
 
 (d)    Changes in Internal Control over Financial Reporting
 
There were no changes in our internal control over financial reporting that occurred during the period ended December 31, 2007 that have materially affected, or that were reasonably likely to materially affect, our internal control over financial reporting.
 
ITEM 16A.  AUDIT COMMITTEE FINANCIAL EXPERT
 
Mr. Aloysius Hau Yin Tse has been designated by our Board as an audit committee financial expert.  Mr. Tse is independent as defined in the listing standards of the New York Stock Exchange.
 
ITEM 16B.  CODE OF ETHICS
 
Our Board adopted a code of ethics on August 28, 2003 to provide guidelines to our senior management and directors in legal and ethical matters as well as the sensitivities involved in reporting illegal and unethical matters.  Such code of ethics covers such areas as supervisory rules, insider dealing, market malpractices, conflict of interests, company opportunities, protection and proper use of our assets as well as reporting requirements.  We reviewed our code of ethics and adopted a revised code of ethics in 2005, as part of our continuing efforts to improve our corporate governance standards.  The revised code of ethics clarified the scope of senior management, and expanded the applicability of prohibitions against insider trading and other market misconduct.
 
We have provided all our directors and senior officers with a copy of the revised code of ethics and require them to comply with the revised code of ethics, so as to ensure our operations are proper and lawful.  We will take disciplinary actions towards any act which is in breach of the revised code of ethics.  Any change or waiver, explicit or implicit, with respect to our revised code of ethics, must be disclosed to our shareholders either in our annual report or on our internet website, www.cnoocltd.com.
 
ITEM 16C.  PRINCIPAL ACCOUNTANT FEES AND SERVICES
 
Audit Fees
 
The aggregate fees billed for professional services rendered by our principal accountants for the audit of our annual financial statements or services that are normally provided by the accountants in connection with statutory and regulatory filings or engagements were Rmb 10.4 million for 2006 and Rmb 14.4 million (US$2.0 million) for 2007.

The aggregate fees billed for products and services provided by our principal accountant, other than the services reported above, were nil for fiscal years 2006 and 2007.
 
Audit Committee’s pre-approval policies and procedures
 
Our audit committee under our Board is responsible for the appointment, compensation and oversight of the work of our principal accountant. In 2003, our audit committee adopted a policy calling for the audit committee’s pre-approval for the engagement of our principal accountant for audit and permitted non-audit services.  Our Board has also ratified the policy and procedures.  Under this audit committee policy, proposed services may be pre-approved by our audit committee either on an annual basis or on a case-by-case basis.  Appendices to the audit committee policy set forth (1) the audit, audit-related, tax and other services that may be subject to the general annual pre-approval of the audit committee; (2) non-audit services of a routine and recurring nature that may be subject to specific pre-approval from the audit committee on a case-by-case basis; and (3) a list of prohibited non-audit services.  Our audit committee will periodically review and revise these appendices based on its subsequent determinations.  The audit committee policy also provides for procedures to establish annual fee levels or budgets for pre-approved services and ratios between different categories of pre-approved services.  In addition, the audit committee policy contains provisions that deal with compliance, monitoring, reporting and other related matters.
 
During 2007, all fees for audit-related services, tax services and all other services paid to our principal accountant were approved by our audit committee.

(Incorporated in Hong Kong with limited liability)

We have audited the accompanying consolidated balance sheets of CNOOC Limited (the “Company”) and its subsidiaries (the “Group”) as of December 31, 2007 and 2006, and the related consolidated statements of income, changes in shareholders' equity and cash flows for each of the three years in the period ended December 31, 2007. These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States) and Hong Kong Standards on Auditing issued by the Hong Kong Institute of Certified Public Accountants. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of the Group at December 31, 2007 and 2006 and the consolidated results of their operations and their cash flows for each of the three years in the period ended December 31, 2007, in conformity with accounting principles generally accepted in Hong Kong (“Hong Kong GAAP”).

Accounting principles generally accepted in Hong Kong vary in certain significant aspects from U.S. generally accepted accounting principles. Information relating to the nature and effect of such differences is presented in note 39 to the consolidated financial statements.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the Group's internal control over financial reporting as of December 31, 2007, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated March 27, 2008 expressed an unqualified opinion thereon.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM ON INTERNAL CONTROL OVER FINANCIAL REPORTING

 
The Board of Directors and Shareholders of CNOOC Limited
(Incorporated in Hong Kong with limited liability)

We have audited CNOOC Limited’s internal control over financial reporting as of December 31, 2007, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (the COSO criteria). CNOOC Limited’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying “Management’s annual report on internal control over financial reporting”. Our responsibility is to express an opinion on the company’s internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, CNOOC Limited maintained, in all material respects, effective internal control over financial reporting as of December 31, 2007, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of CNOOC Limited as of December 31, 2007 and 2006, and the related consolidated statements of income, changes in shareholders’ equity and cash flows for each of the three years in the period ended December 31, 2007 of CNOOC Limited and our report dated March 27, 2008 expressed an unqualified opinion thereon.

2.1
IMPACT OF NEW AND REVISED HONG KONG FINANCIAL REPORTING STANDARDS (“HKFRSs”)

The Hong Kong Institute of Certified Public Accountants has issued the following new and amended HKFRSs, which are mandatory for annual periods beginning on or after January 1, 2007:
 
HKAS 1 Amendment
Capital Disclosures
HKFRS 7
Financial Instruments: Disclosures
HK (IFRIC)-Int 8
Scope of HKFRS 2
HK (IFRIC)-Int 9
Reassessment of Embedded Derivatives
HK (IFRIC)-Int 10
Interim Financial Reporting and Impairment
 
The principal effects of adopting these new and revised HKFRSs are as follows:

 
(a)
HKAS 1 Amendment requires the Group to make disclosures that enable users of the financial statements to evaluate the Group’s objectives, policies and processes for managing capital. These new disclosures are included in note 35 to the financial statements.

2.1
IMPACT OF NEW AND REVISED HONG KONG FINANCIAL REPORTING STANDARDS (“HKFRSs”) (CONTINUED)

(b)
HKFRS 7 requires disclosures that enable users of the financial statements to evaluate the significance of the Group’s financial instruments and the nature and extent of risks arising from those financial instruments. The new disclosures are included throughout the financial statements. While there has been no impact on the financial position or results of operations of the Group, comparative information has been included/revised where appropriate.

(c)
HK(IFRIC)-Int 8 requires HKFRS 2 to be applied to any arrangement in which the Group cannot identify specifically some or all of the goods or services received, for which equity instruments are granted or liabilities (based on a value of the Group’s equity instruments) are incurred by the Group for a consideration, and which appears to be less than the fair value of the equity instruments granted or liabilities incurred. As the Company has only issued equity instruments to the Group’s employees in accordance with the Company’s share option scheme, the interpretation has had no impact on the financial position or results of operations of the Group.

(d)
HK(IFRIC)-Int 9 requires that the date to assess whether an embedded derivative is required to be separated from the host contract and accounted for as a derivative is the date that the Group first becomes a party to the contract, with reassessment only if there is a change to the contract that significantly modifies the cash flows. As the Group’s existing policy of accounting for derivatives complies with the requirements of the interpretation, the interpretation has had no impact on the financial position or results of operations of the Group.

(e)
The Group has adopted HK(IFRIC)-Int 10 as of January 1, 2007, which requires that an impairment loss recognised in a previous interim period in respect of goodwill or an investment in either an equity instrument classified as available-for-sale or a financial asset carried at cost is not subsequently reversed. As the Group had no impairment losses previously reversed in respect of such assets, the interpretation has had no impact on the financial position or results of operations of the Group.

2.2
IMPACT OF ISSUED BUT NOT YET EFFECTIVE HONG KONG FINANCIAL REPORTING STANDARDS

The Hong Kong Institute of Certified Public Accountants has issued a number of new and revised HKFRSs that are not mandatory for these financial statements. The Group has not early applied these HKFRSs in these financial statements. Unless otherwise stated, the following HKFRSs are effective for accounting periods beginning on or after January 1, 2008:
 
HKAS 1 (Revised)
Presentation of Financial Statements
HKAS 23 (Revised)
Borrowing Costs
HKFRS 8
Operating Segments
HK(IFRIC)-Int 11
HKFRS 2-Group and Treasury Share Transactions
 
HKAS 1 (Revised) requires an entity to present, in a statement of changes in equity, all owner changes in equity. All non-owner changes in equity (comprehensive income) are required to be presented in one statement of comprehensive income or in two statements (a separate income statement and a statement of comprehensive income). It also requires an entity to present a statement of financial position as at the beginning of the earliest comparative period in a complete set of financial statements and disclose reclassification adjustments and income tax relating to each component of other comprehensive income. Dividends recognised as distributions to owners and related amounts per share are required to be presented in the statement of changes in equity or in the notes.

2.2
IMPACT OF ISSUED BUT NOT YET EFFECTIVE HONG KONG FINANCIAL REPORTING STANDARDS (CONTINUED)

HKAS 23 has been revised to require capitalisation of borrowing costs when such costs are directly attributable to the acquisition, construction or production of a qualifying asset. As the Group’s current policy for borrowing costs aligns with the requirements of the revised standard, the revised standard is unlikely to have any financial impact on the Group.

HKFRS 8, which will replace HKAS 14 Segment Reporting, specifies how an entity should report information about its operating segments, based on information about the components of the entity that is available to the chief operating decision maker for the purposes of allocating resources to the segments and assessing their performance. The standard also requires the disclosure of information about the products and services provided by the segments, the geographical areas in which the Group operates, and revenue from the Group’s major customers. The Group expects to adopt HKFRS 8 from January 1, 2009.

HK(IFRIC)-Int 11 requires arrangements whereby an employee is granted rights to the Group’s equity instruments, to be accounted for as an equity-settled scheme, even if the Group acquires the instruments from another party, or the shareholders provide the equity instruments needed. HK(IFRIC)-Int 11 also addresses the accounting for share-based payment transactions involving two or more entities within the Group. As the Group currently has no such transactions, the interpretation is unlikely to have any financial impact on the Group.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of preparation
These financial statements have been prepared in accordance with Hong Kong Financial Reporting Standards (which include all Hong Kong Financial Reporting Standards, Hong Kong Accounting Standards (“HKASs”) and Interpretations) issued by the Hong Kong Institute of Certified Public Accountants (the “HKICPA”), accounting principles generally accepted in Hong Kong (“Hong Kong GAAP”) and the disclosure requirements of the Hong Kong Companies Ordinance. They have been prepared under the historical cost convention, except for available-for-sale investments and derivative financial instruments which have been measured at fair value. These financial statements are presented in Renminbi (“RMB”) and all values are rounded to the nearest thousand except when otherwise indicated.

Basis of consolidation
The consolidated financial statements include the financial statements of the Company and its subsidiaries for the year ended December 31, 2007. The results of subsidiaries are consolidated from the date of acquisition being the date on which the Group obtains control and continue to be consolidated until the date that such control ceases. All significant intercompany transactions and balances within the Group are eliminated on consolidation.

The acquisition of subsidiaries has been accounted for using the purchase method of accounting. This method involves allocating the cost of the business combinations to the fair value of the identifiable assets acquired, and liabilities and contingent liabilities assumed at the date of acquisition. The cost of the acquisition is measured at the aggregate of the fair value of the assets given, equity instruments issued (if any) and liabilities incurred or assumed at the date of exchange, plus costs directly attributable to the acquisition.

Minority interests represent the interests of outside shareholders not held by the Group in the results and net assets of the Company’s subsidiaries.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

Subsidiaries
A subsidiary is an entity in which the Company, directly or indirectly, controls more than half of its voting power or issued share capital or controls the composition of its board of directors; or over which the Company has a contractual right to exercise a dominant influence with respect to that entity’s financial and operating policies.

The results of subsidiaries are included in the Company’s income statement to the extent of dividends received and receivable. The Company’s interests in subsidiaries are stated at cost less any impairment losses.

Associates
An associate is an entity, not being a subsidiary or a jointly-controlled entity, in which the Group has a long term interest of generally not less than 20% of the equity voting rights and over which it is in a position to exercise significant influence.

The Group’s share of the post-acquisition results and reserves of the associates are included in the consolidated income statement and consolidated reserves, respectively. The Group’s interests in associates are stated in the consolidated balance sheet at the Group’s share of net assets under the equity method of accounting, less any impairment losses. Unrealised gains and losses resulting from transactions between the Group and its associates are eliminated to the extent of the Group’s interests in the associates, except where unrealised losses provide evidence of an impairment of the asset transferred.

The results of associates are included in the Company’s income statement to the extent of dividends received and receivable. The Company’s interests in associates are treated as non-current assets and are stated at cost less any impairment losses.

Joint ventures
Certain of the Group’s activities are conducted through joint arrangements, including the production sharing arrangements detailed in note 4 below. These arrangements are a form of joint venture whereby a contractual arrangement exists between two or more parties to undertake an economic activity that is subject to joint control. These joint arrangements are included in the consolidated financial statements in proportion to the Group’s interests in the income, expenses, assets and liabilities of these arrangements.

Related parties
A party is considered to be related to the Group if:

(a)
the party, directly or indirectly through one or more intermediaries, (i) controls, is controlled by, or is under common control with, the Group; (ii) has an interest in the Group that gives it significant influence over the Group; or (iii) has joint control over the Group;

(b)
the party is an associate;

(c)
the party is a jointly controlled entity;

(d)
the party is a member of the key management personnel of the Group or its parent;

(e)
the party is a close member of the family of any individual referred to in (a) or (d); or

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

Related parties (continued)

(f)
the party is an entity that is controlled, jointly controlled or significantly influenced by or for which significant voting power in such entity resides with, directly or indirectly, any individual referred to in (d) or (e).

Impairment of non-financial assets other than goodwill
Where an indication of impairment exists, or when annual impairment testing for an asset is required (other than inventories, deferred tax assets and financial assets), the asset’s recoverable amount is estimated. An asset’s recoverable amount is calculated as the higher of the asset’s or cash-generating unit’s value in use and its fair value less costs to sell, and is determined for an individual asset, unless the asset does not generate cash inflows that are largely independent of those from other assets or groups of assets, in which case the recoverable amount is determined for the cash-generating unit to which the asset belongs.

An impairment loss is recognised only if the carrying amount of an asset exceeds its recoverable amount. In assessing value in use, the estimated future cash flows are discounted to their present value using a pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the asset. An impairment loss is charged to the consolidated income statement in the period in which it arises.

An assessment is made at each reporting date as to whether there is any indication that previously recognised impairment losses may no longer exist or may have decreased. If such indication exists, the recoverable amount is estimated. A previously recognised impairment loss of an asset other than goodwill is reversed only if there has been a change in the estimates used to determine the recoverable amount of that asset, but not to an amount higher than the carrying amount that would have been determined (net of any depreciation/amortisation) had no impairment loss been recognised for the asset in prior years. A reversal of an impairment loss is credited to the consolidated income statement in the period in which it arises.

Property, plant and equipment and depreciation
Property, plant and equipment comprise oil and gas properties, and vehicles and office equipment.

(i)
Oil and gas properties
For oil and gas properties, the successful efforts method of accounting is adopted. The Group capitalises the initial acquisition costs of oil and gas properties. Impairment of initial acquisition costs is recognised based on exploratory experience and management judgment. Upon discovery of commercial reserves, acquisition costs are transferred to proved properties. The costs of drilling and equipping successful exploratory wells, all development expenditures on construction, installation or completion of infrastructure facilities such as platforms, pipelines, processing plants and the drilling of development wells, including those renewals and betterments that extend the economic lives of the assets, and the related borrowing costs are capitalised. The costs of unsuccessful exploratory wells and all other exploration costs are expensed as incurred.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

Property, plant and equipment and depreciation (continued)

(i)
Oil and gas properties (continued)
The Group carries exploratory well costs as an asset when the well has found a sufficient quantity of reserves to justify its completion as a producing well and where the Group is making sufficient progress assessing the reserves and the economic and operating viability of the project. Exploratory well costs not meeting these criteria are charged to expense. Exploratory wells that discover potentially economic reserves in areas where major capital expenditure will be required before production would begin and when the major capital expenditure depends upon the successful completion of further exploratory work remain capitalised and are reviewed periodically for impairment.

Productive oil and gas properties and other tangible and intangible costs of producing properties are amortised using the unit-of-production method on a property-by-property basis under which the ratio of produced oil and gas to the estimated remaining proved developed reserves is used to determine the provision of depreciation, depletion and amortisation. Common facilities that are built specifically to service production directly attributed to designated oil and gas properties are amortised based on the proved developed reserves of the respective oil and gas properties on a pro-rata basis. Common facilities that are not built specifically to service identified oil and gas properties are depreciated using the straight-line method over their estimated useful lives. Costs associated with significant development projects are not depleted until commercial production commences and the reserves related to those costs are excluded from the calculation of depletion.

Capitalised acquisition costs of proved properties are amortised by the unit-of-production method on a property-by-property basis computed according to the total estimated units of proved reserves.

The Group estimates future dismantlement costs for oil and gas properties with reference to the estimates provided from either internal or external engineers after taking into consideration the anticipated method of dismantlement required in accordance with the current legislation and industry practices. The associated cost is capitalised and the liability is discounted and an accretion expense is recognised using the credit-adjusted risk-free interest rate in effect when the liability is initially recognised. No market-risk premium has been included in the Company’s calculation of asset retirement obligations balances since no reliable estimate can be made by the Company.

(ii)
Vehicles and office equipment
Vehicles and office equipment are stated at cost less accumulated depreciation and impairment losses. The straight-line method is adopted to depreciate the cost less any estimated residual value of these assets over their expected useful lives. The Group estimates the useful lives of vehicles and office equipment to be five years.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

Property, plant and equipment and depreciation (continued)

(ii)
Vehicles and office equipment (continued)
When an item of property, plant and equipment is classified as held for sale or when it is part of a disposal group classified as held for sale, it is not depreciated and is accounted for in accordance with HKFRS 5, as further explained in the accounting policy for “Non-current assets and disposal groups held for sale”. The cost of an item of property, plant and equipment comprises its purchase price and any directly attributable costs of bringing the asset to its working condition and location for its intended use. Expenditure incurred after items of property, plant and equipment, have been put into operation, such as repairs and maintenance, is normally charged to the consolidated income statement in the period in which it is incurred. In situations where it can be clearly demonstrated that the expenditure has resulted in an increase in the future economic benefits expected to be obtained from the use of an item of property, plant and equipment, and where the cost of the item can be measured reliably, the expenditure is capitalised as an additional cost of that asset or as a replacement.

Where parts of an item of property, plant and equipment have different useful lives, the cost of that item is allocated on a recoverable basis among the parts and each part is depreciated separately.

Residual values, useful lives and the depreciation method are reviewed and, adjusted if appropriate, at each balance sheet date.

An item of property, plant and equipment is derecognised upon disposal or when no future economic benefits are expected from its use or disposal. Any gain or loss on disposal or retirement recognised in the consolidated income statement in the year that the asset is derecognised is the difference between the net sales proceeds and the carrying amount of the relevant asset.

Non-current assets and disposal groups held for sale
Non-current assets and disposal groups are classified as held for sale if their carrying amounts will be recovered principally through a sale transaction rather than through continuing use. For this to be the case, the asset or disposal group must be available for immediate sale in its present condition subject only to terms that are usual and customary for the sale of such assets or disposal groups and its sale must be highly probable.

Non-current assets and disposal groups (other than investment properties, deferred tax assets and financial assets) classified as held for sale are measured at the lower of their carrying amounts and fair values less costs to sell.

Intangible assets
The useful lives of intangible assets are assessed to be either finite or indefinite. Intangible assets with finite lives are amortised over the useful economic life and assessed for impairment whenever there is an indication that the intangible asset may be impaired.

3.
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
 
Intangible assets (continued)
The amortisation period and the amortisation method for an intangible asset with a finite useful life are reviewed at least at each balance sheet date.

Research and development costs
All research costs are charged to the consolidated income statement as incurred.

Expenditure (other than relating to oil and gas properties discussed above) incurred on projects to develop new products is capitalised and deferred only when the Group can demonstrate the technical feasibility of completing the intangible asset so that it will be available for use or sale, its intention to complete and its ability to use or sell the asset, how the asset will generate future economic benefits, the availability of resources to complete the project and the ability to measure reliably the expenditure during the development. Product development expenditure which does not meet these criteria is expensed when incurred. No development costs were capitalised during the year.
 
Investments and other financial assets
Financial assets within the scope of HKAS 39 are classified as financial assets at fair value through profit or loss, loans and receivables, held-to-maturity financial asset, and available-for-sale financial assets, as appropriate. When financial assets are recognised initially, they are measured at fair value, plus, in the case of investments not at fair value through profit or loss, directly attributable transaction costs.

The Group assesses whether a contract contains an embedded derivative when the Group first becomes a party to it and assesses whether an embedded derivative is required to be separated from the host contract when the analysis shows that the economic characteristics and the risks of the embedded derivative are not closely related to those of the host contract. Reassessment only occurs if there is a change in the terms of the contract that significantly modifies the cash flows that would otherwise be required under the contract.

The Group determines the classification of its financial assets after initial recognition and, where allowed and appropriate, re-evaluates this designation at the balance sheet date.

All regular way purchases and sales of financial assets are recognised on the trade date, that is, the date that the Group commits to purchase or sell the asset. Regular way purchases or sales are purchases or sales of financial assets that require delivery of assets within the period generally established by regulation or convention in the marketplace.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

Investments and other financial assets (continued)

(a)
Financial assets at fair value through profit or loss
Financial assets at fair value through profit or loss include financial assets held for trading and financial assets designated upon initial recognition as at fair value through profit or loss. Financial assets are classified as held for trading if they are acquired for the purpose of sale in the near term. Derivatives, including separated embedded derivatives, are also classified as held for trading unless they are designated as effective hedging instruments or financial guarantee contracts. Gains or losses on investments held for trading or these financial assets are recognised in the consolidated income statement. The net fair value gain or loss recognised in the consolidated income statement does not include any dividends or interest earned on these financial assets, which are recognised in accordance with the policies set out for “Revenue recognition” below.

Where a contract contains one or more embedded derivatives, the entire hybrid contract may be designated as a financial asset at fair value through profit or loss, except where the embedded derivative does not significantly modify the cash flows or it is clear that separation of the embedded derivative is prohibited.

Financial assets may be designated upon initial recognition as at fair value through profit or loss if the following criteria are met:

 
(i)
the designation eliminates or significantly reduces the inconsistent treatment that would otherwise arise from measuring the assets or recognising gains or losses on them on a different basis;

 
(ii)
the assets are part of a group of financial assets which are managed and their performance evaluated on a fair value basis, in accordance with a documented risk management strategy; or

 
(iii)
the financial asset contains an embedded derivative that would need to be separately recorded.

(b)
Loans and receivables
Loans and receivables are non-derivative financial assets with fixed or determinable payments that are not quoted in an active market. Such assets are subsequently carried at amortised cost using the effective interest method less any allowance for impairment. Amortised cost is calculated taking into account any discount or premium on acquisition and includes fees that are an integral part of the effective interest rate and transaction costs. Gains and losses are recognised in the consolidated income statement when the loans and receivables are derecognised or impaired, as well as through the amortisation process.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

Investments and other financial assets (continued)

(c)
Held-to-maturity financial asset
Non-derivative financial assets with fixed or determinable payments and fixed maturity are classified as held-to-maturity when the Group has the positive intention and ability to hold to maturity. Held-to-maturity investments are subsequently measured at amortised cost less any allowance for impairment. Amortised cost is computed as the amount initially recognised minus principal repayments, plus or minus the cumulative amortisation using the effective interest method of any difference between the initially recognised amount and the maturity amount.

(d)
Available-for-sale financial assets
Available-for-sale financial assets are non-derivative financial assets in listed and unlisted equity securities that are designated as available-for-sale or are not classified in any of the other three categories. After initial recognition available-for-sale financial assets are measured at fair value, with gains or losses recognised as a separate component of equity until the investment is derecognised or until the investment is determined to be impaired, at which time the cumulative gain or loss previously reported in equity is included in the consolidated income statement. Interest and dividends earned are reported as interest income and dividend income, respectively and are recognised in the consolidated income statement as “Investment income”. Losses arising from the impairment of such investments, if any, are recognised in the consolidated income statement as “Impairment losses on available-for-sale financial assets” and are transferred from the available-for-sale investment revaluation reserve.

When the fair value of unlisted equity securities cannot be reliably measured because (a) the variability in the range of reasonable fair value estimates is significant for that investment or (b) the probabilities of the various estimates within the range cannot be reasonably assessed and used in estimating fair value, such securities are stated at cost less any impairment losses.
 
Fair value
The fair value of investments that are actively traded in organised financial markets is determined by reference to the quoted market bid price at the close of business at the balance sheet date. For investments where there is no active market, fair value is determined using valuation techniques. Such techniques include using recent arm’s length market transactions; reference to the current market value of another instrument which is substantially the same; a discounted cash flow analysis; and option pricing models.
 
Impairment of financial assets
The Group assesses at each balance sheet date whether there is any objective evidence that a financial asset or a group of financial assets is impaired.

(All amounts expressed in Renminbi unless otherwise stated)

3.
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

Assets carried at amortised cost
If there is objective evidence that an impairment loss on loans and receivables or held-to-maturity investments carried at amortised cost has been incurred, the amount of the loss is measured as the difference between the asset’s carrying amount and the present value of estimated future cash flows (excluding future credit losses that have not been incurred) discounted at the financial asset’s original effective interest rate (the effective interest rate computed at initial recognition). The carrying amount of the asset is reduced either directly or through the use of an allowance account. The amount of the impairment loss is recognised in the consolidated income statement. Loans and receivables together with any associated allowance are written off when there is no realistic prospect of future recovery.

If, in a subsequent period, the amount of the impairment loss decreases and the decrease can be related objectively to an event occurring after the impairment was recognised, the previously recognised impairment loss is reversed by adjusting the allowance account. Any subsequent reversal of an impairment loss is recognised in the consolidated income statement, to the extent that the carrying value of the asset does not exceed its amortised cost at the reversal date.

In relation to trade and other receivables, a provision for impairment is made when there is objective evidence (such as the probability of insolvency or significant financial difficulties of the debtor and significant changes in the technological, market economic or legal environment that have an adverse effect on the debtor) that the Group will not be able to collect all of the amounts due under the original terms of an invoice. The carrying amount of the receivables is reduced through the use of an allowance account. Impaired debts are derecognised when they are assessed as uncollectible.

Assets carried at cost
If there is objective evidence that an impairment loss has been incurred on an unquoted equity instrument that is not carried at fair value because its fair value cannot be reliably measured, the amount of the loss is measured as the difference between the asset’s carrying amount and the present value of estimated future cash flows discounted at the current market rate of return for a similar financial asset. Impairment losses on these assets are not reversed.

Available-for-sale financial assets
If an available-for-sale asset is impaired, an amount comprising the difference between its cost (net of any principal payment and amortisation) and its current fair value, less any impairment loss previously recognised in the consolidated income statement, is transferred from equity to the consolidated income statement. A provision for impairment is made for available-for-sale equity investments when there has been a significant or prolonged decline in the fair value below its cost or where other objective evidence of impairment exists. The determination of what is “significant” or “prolonged” requires judgement. In addition, the Group evaluates other factors, such as the share price volatility. Impairment losses on equity instruments classified as available-for-sale are not reversed through the consolidated income statement.

Impairment losses on debt instruments are reversed through the consolidated income statement, if the increase in fair value of the instrument can be objectively related to an event occurring after the impairment loss was recognised in the consolidated income statement.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

Derecognition of financial assets
A financial asset (or, where applicable, a part of a financial asset or part of a group of similar financial assets) is derecognised where:

 
the rights to receive cash flows from the asset have expired;

 
the Group retains the rights to receive cash flows from the asset, but has assumed an obligation to pay them in full without material delay to a third party under a “pass-through” arrangement; or

 
the Group has transferred its rights to receive cash flows from the asset and either (a) has transferred substantially all the risks and rewards of the asset, or (b) has neither transferred nor retained substantially all the risks and rewards of the asset, but has transferred control of the asset.

Where the Group has transferred its rights to receive cash flows from an asset and has neither transferred nor retained substantially all the risks and rewards of the asset nor transferred control of the asset, the asset is recognised to the extent of the Group’s continuing involvement in the asset. Continuing involvement that takes the form of a guarantee over the transferred asset is measured at the lower of the original carrying amount of the asset and the maximum amount of consideration that the Group could be required to repay.

Where continuing involvement takes the form of a written and/or purchased option (including a cash-settled option or similar provision) on the transferred asset, the extent of the Group’s continuing involvement is the amount of the transferred asset that the Group may repurchase, except that in the case of a written put option (including a cash-settled option or similar provision) on an asset measured at fair value, where the extent of the Group’s continuing involvement is limited to the lower of the fair value of the transferred asset and the option exercise price.

Financial liabilities at amortised cost (including interest-bearing loans and borrowings)
Financial liabilities including trade and other payables, amount due to the parent company, amount due to related companies and interest-bearing loans and borrowings are initially stated at fair value including directly attributable transaction costs and are subsequently measured at amortised cost, using the effective interest method unless the effect of discounting would be immaterial, in which case they are stated at cost. The related interest expense is recognised within “finance costs” in the consolidated income statement.

Gains and losses are recognised in the consolidated income statement when the liabilities are derecognised as well as through the amortisation process.

Financial guarantee contracts
Financial guarantee contracts in the scope of HKAS 39 are accounted for as financial liabilities. A financial guarantee contract is recognised initially as its fair value including transaction costs that are directly attributable to the acquisition or issue of the financial guarantee contract, except when such contract is recognised at fair value through profit or loss. Subsequent to initial recognition, the Group measures the financial guarantee contract at the higher of: (i) the amount determined in accordance with HKAS 37 Provisions, Contingent Liabilities and Contingent Assets; and (ii) the amount initially recognised less, when appropriate, cumulative amortisation recognised in accordance with HKAS 18 Revenue.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
 
Convertible bonds
For the accounting periods prior to July 27, 2007, the Group’s convertible bonds issued with a cash settlement option and other embedded derivative features were split into liability and derivative components according to their fair values for measurement purposes.
 
The fair value of the liability component is determined using the market rate for an equivalent non-convertible bond on the issuance of convertible bonds and this amount is carried as a long term liability on the amortised cost basis until extinguished on conversion or redemption. The derivative component was remeasured at each balance sheet date and any gains or losses arising from change in the fair value were recognised in the consolidated income statement upto July 27, 2007 when the Group renounced the cash settlement option and the embedded derivative component was reclassified from a financial liability to other reserves included in shareholders’ equity.
 
Derecognition of financial liabilities
 
A financial liability is derecognised when the obligation under the liability is discharged or cancelled or expires.
 
When an existing financial liability is replaced by another from the same lender on substantially different terms, or the terms of an existing liability are substantially modified, such an exchange or modification is treated as a derecognition of the original liability and a recognition of a new liability, and the difference between the respective carrying amounts is recognised in the consolidated income statement.
 
Derivative financial instruments
 
The Group uses currency swaps, classified as derivative financial instruments, to hedge its risks associated with currency exchange fluctuations. Such derivative financial instruments are initially recognised at fair value on the date on which a derivative contract is entered into and are subsequently remeasured at fair value. Derivatives are carried as assets when the fair value is positive and as liabilities when the fair value is negative.
 
Any gains or losses arising from changes in fair value on derivatives that do not qualify for hedge accounting are taken directly to the consolidated income statement.
 
The fair value of currency swap contracts is determined by reference to market values for similar instruments.
 
Inventories and supplies
Inventories primarily consist of oil and supplies, which mainly consist of items for repairs and maintenance of oil and gas properties. Inventories are stated at the lower of cost and net realisable value. Costs of inventories and supplies represent purchase or production cost of goods and are determined on a weighted average basis. Net realisable value is based on estimated selling prices less any estimated costs to be incurred to completion and disposal. Supplies are capitalised to property, plant and equipment when used for the renewal and betterment of oil and gas properties and have resulted in an increase in the future economic values of oil and gas properties or are recognised as expenses when used.
 
Cash and cash equivalents
For the purpose of the consolidated cash flow statement, cash and cash equivalents comprise cash on hand and demand deposits, and short term highly liquid investments that are readily convertible into known amounts of cash are subject to an insignificant risk of changes in value, and have a short maturity of generally within three months when acquired, less bank overdrafts which are repayable on demand and form an integral part of the Group’s cash management.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
 
Cash and cash equivalents (continued)
For the purpose of the balance sheets, cash and cash equivalents comprise cash on hand and at banks, including term deposits with maturity of three months or less which are not restricted to use.

Provisions
A provision is recognised when a present obligation (legal or constructive) has arisen as a result of a past event and it is probable that a future outflow of resources will be required to settle the obligation, provided that a reliable estimate can be made of the amount of the obligation.
 
When the effect of discounting is material, the amount recognised for a provision is the present value at the balance sheet date of the future expenditures expected to be required to settle the obligation. The increase in the discounted present value amount arising from the passage of time is included in finance costs in the consolidated income statement.
 
Provisions for dismantlement are made based on the present value of the future costs expected to be incurred, on a property-by-property basis, in respect of the Group’s expected dismantlement and abandonment costs at the end of the related oil exploration and recovery activities.
 
Income tax
Income tax comprises current and deferred tax. Income tax is recognised in the consolidated income statement, or in equity if it relates to items that are recognised in the same or a different period directly in equity.
 
Current tax assets and liabilities for the current and prior periods are measured at the amount expected to be recovered from or paid to the taxation authorities.
 
Deferred tax is provided, using the liability method, on all temporary differences at the balance sheet date between the tax bases of assets and liabilities and their carrying amounts for financial reporting purposes.
 
Deferred tax liabilities are recognised for all taxable temporary differences, except:
 
 
where the deferred tax liability arises from the initial recognition of an asset or liability in a transaction that is not a business combination and, at the time of the transaction, affects neither the accounting profit nor taxable profit or loss; and

 
in respect of taxable temporary differences associated with investments in subsidiaries, associates and interests in joint ventures, where the timing of the reversal of the temporary differences can be controlled and it is probable that the temporary differences will not reverse in the foreseeable future.

Deferred tax assets are recognised for all deductible temporary differences, carryforward of unused tax credits and unused tax losses, to the extent that it is probable that taxable profit will be available against which the deductible temporary differences, and the carryforward of unused tax credits and unused tax losses can be utilised, except:

 
where the deferred tax assets relating to the deductible temporary differences arise from the initial recognition of an asset or liability in a transaction that is not a business combination and, at the time of the transaction, affects neither the accounting profit nor taxable profit or loss; and

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
 
Income tax (continued)
 
in respect of deductible temporary differences associated with investments in subsidiaries, associates and interests in joint ventures, deferred tax assets are only recognised to the extent that it is probable that the temporary differences will reverse in the foreseeable future and taxable profit will be available against which the temporary differences can be utilised.

The carrying amount of deferred tax assets is reviewed at each balance sheet date and reduced to the extent that it is no longer probable that sufficient taxable profit will be available to allow all or part of the deferred tax asset to be utilised. Conversely, previously unrecognised deferred tax assets are reassessed at each balance sheet date and are recognised to the extent that it is probable that sufficient taxable profit will be available to allow all or part of the deferred tax asset to be utilised.

Deferred tax assets and liabilities are measured at the tax rates that are expected to apply to the period when the asset is realised or the liability is settled, based on tax rates (and tax laws) that have been enacted or substantively enacted at the balance sheet date.

Deferred tax assets and deferred tax liabilities are offset if a legally enforceable right exists to set off current tax assets against current tax liabilities and the deferred taxes relate to the same taxable entity and the same taxation authority.

Revenue recognition
Revenue is recognised when it is probable that the economic benefits will flow to the Group and when the revenue can be measured reliably, on the following bases:

(i)
Oil and gas sales
Oil and gas sales represent the invoiced value of sales of oil and gas attributable to the interests of the Group, net of royalties and the PRC government share oil that are lifted and sold on behalf of the PRC government. Sales are recognised when the significant risks and rewards of ownership of oil and gas have been transferred to customers.

Oil and gas lifted and sold by the Group above or below the Group’s participating interests in the production sharing contracts results in overlifts and underlifts. The Group records these transactions in accordance with the entitlement method under which overlifts are recorded as liabilities and underlifts are recorded as assets at year end oil prices. Settlement will be in kind when the liftings are equalised or in cash when production ceases.

The Group has entered into gas sales contracts with customers, which contain take-or-pay clauses. The clauses require those customers to take a specified minimum volume of gas each year. If the minimum volume of gas is not taken, those customers must pay for the deficiency gas, even though the gas is not taken. Those customers can offset the deficiency payment against any future purchases in excess of the specified volume. The Group records any deficiency payments as deferred revenue which is included in other payables until the make-up gas is taken by those customers or the expiry of the contracts.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

Revenue recognition (continued)

(ii)
Marketing revenues
Marketing revenues represent the sales of oil and gas purchased from the foreign partners under the production sharing contracts and revenues from the trading of oil and gas through the Company’s subsidiary in Singapore. The title, together with the risks and rewards of the ownership of such oil purchased from the foreign partners, is transferred to the Group from the foreign partners and other unrelated oil and gas companies before the Group sells such oil to its customers. The cost of the oil and gas sold is included in “crude oil and product purchases”.

(iii)
Other income
Other income mainly represents project management fees charged to the foreign partners and handling fees charged to customers and is recognised when the services have been rendered. Reimbursement of insurance claim is recognised when the compensation becomes receivable.

(iv)
Dividend income
Dividend income is recognised when the shareholders’ right to receive payment has been established.

(v)
Interest income
Interest income from deposits placed with banks and other financial institutions is recognised on a time proportion basis taking into account the effective yield on the assets.

The Group presents taxes collected from customers in the consolidated income statement on a net basis.

Employee benefits
Share-based payment transactions
The Company has adopted share option schemes for the purpose of providing incentives and rewards to eligible participants who contribute to the success of the Group’s operations. Employees (including directors) of the Group receive remuneration in the form of share-based payment transactions, whereby employees render services as consideration for equity instruments (“equity-settled transactions”).

The cost of equity-settled transactions with employees is measured by reference to the fair value at the date at which they are granted. The fair value is determined by using the Black-Scholes model, further details of which are given in note 29. In valuing equity-settled transactions, no account is taken of any performance conditions, other than conditions linked to the price of the shares of the Company, if applicable.

The cost of equity-settled transactions is recognised, together with a corresponding increase in equity, over the period in which the performance and/or service conditions are fulfilled, ending on the date on which the relevant employees become fully entitled to the award (the “vesting date”). The cumulative expenses recognised for equity-settled transactions at each balance sheet date until the vesting date reflects the extent to which the vesting period has expired and the Group’s best estimate of the number of equity instruments that will ultimately vest. The charge or credit to the income statement for a period represents the movement in the cumulative expense recognised as at the beginning and end of that period.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

Employee benefits
Share-based payment transactions (continued)
No expense is recognised for awards that do not ultimately vest, except for awards where vesting is conditional upon a market condition, which are treated as vesting irrespective of whether or not the market condition is satisfied, provided that all other performance conditions are satisfied.

Where the terms of an equity-settled award are modified, as a minimum, an expense is recognised as if the terms had not been modified. In addition, an expense is recognised for any modification, which increases the total fair value of the share-based payment arrangement, or is otherwise beneficial to the employee as measured at the date of modification.

Where an equity-settled award is cancelled, it is treated as if it had vested on the date of cancellation, and any expenses not yet recognised for the award is recognised immediately. However, if a new award is substituted for the cancelled award, and is designated as a replacement award on the date that it is granted, the cancelled and new awards are treated as if they were a modification of the original award, as described in the previous paragraph.

The dilutive effect of outstanding options is reflected as additional share dilution in the computation of earnings per share.

Retirement and termination benefits
The Group participates in defined contribution plans in accordance with local laws and regulations for full-time employees in the PRC and other countries in which it operates. The plans provide for contributions ranging from 10% to 22% of the employees’ basic salaries. The Group’s contributions to these defined contribution plans are charged to expense in the year to which they relate.

Dividends
Final dividends, if any, proposed by the directors are classified as a separate allocation of retained earnings within the equity section of the balance sheet, until they have been approved by the shareholders in a general meeting. When these dividends have been approved by the shareholders and declared, they are recognised as a liability.

Interim dividends are simultaneously proposed and declared, because the Company’s memorandum and articles of association grant the directors the authority to declare interim dividends. Consequently, interim dividends are recognised immediately as a liability when they are proposed and declared.

Borrowing costs
Borrowing costs directly attributable to the acquisition, construction or production of qualifying assets, i.e., assets that necessarily take a substantial period of time to get ready for their intended use or sale, are capitalised as part of the cost of those assets. The capitalisation of such borrowing costs ceases when the assets are substantially ready for their intended use or sale. Investment income earned on the temporary of specific borrowings pending their expenditure on qualifying assets is deducted from the borrowing costs capitalised.

To the extent that funds are borrowed specifically for the purpose of obtaining a qualifying asset, the amount of borrowing costs eligible for capitalisation on that asset is determined as the actual borrowing costs incurred on those borrowings during the period less any investment income on the temporary investment of those borrowings.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

Borrowing costs (continued)
To the extent that funds are borrowed generally and used for the purpose of obtaining a qualifying asset, the amount of borrowing costs eligible for capitalisation is determined by applying a capitalisation rate to the expenditures on that asset. The capitalisation rate is the weighted average of the borrowing costs applicable to the borrowings of the Group that are outstanding during the period, other than the borrowings made specifically for the purpose of obtaining a qualifying asset. The amount of borrowing costs capitalised incurred during a period should not exceed the amount of borrowing costs incurred during that period.

Borrowing costs include interest charges and other costs incurred in connection with the borrowing of funds, including amortisation of discounts or premiums relating to the borrowing, and amortisation of ancillary costs incurred in connection with arranging the borrowing.

Foreign currencies
These financial statements are presented in RMB. Each entity in the Group maintains its books and records in its own functional currency. Foreign currency transactions are initially recorded using the functional currency rates ruling at the dates of the transactions. Monetary assets and liabilities denominated in foreign currencies are retranslated at the functional currency rates of exchange ruling at the balance sheet date. All differences are taken to the consolidated income statement. Non-monetary items that are measured in terms of historical cost in a foreign currency are translated using the exchange rates at the dates of the initial transactions. Non-monetary items measured at fair value in a foreign currency are translated using the exchange rates at the date when the fair value was determined.

The functional currencies of certain overseas subsidiaries are currencies other than the RMB. As at the balance sheet date, the assets and liabilities of these entities are translated into the presentation currency of the Company at the exchange rates ruling at the balance sheet date, and their income statements are translated into RMB at the weighted average exchange rates for the year. The resulting exchange differences are included in the cumulative translation reserve. On disposal of a foreign entity, the deferred cumulative amount recognised in equity relating to that particular foreign operation is recognised in the consolidated income statement.

For the purpose of the consolidated cash flow statement, the cash flows of overseas subsidiaries are translated into RMB at the exchange rates ruling at the dates of the cash flows. Frequently recurring cash flows of overseas subsidiaries which arise throughout the year are translated into RMB at the weighted average exchange rates for the year.

Repairs and maintenance
Repairs and maintenance are normally charged to the consolidated income statement as operating expenses in the period in which they are incurred.

Operating leases
Leases where substantially all the rewards and risks of ownership of assets remain with the lessor are accounted for as operating leases. Where the Group is the lessee, rentals payable under the operating leases are charged to the consolidated income statement on the straight-line basis over the lease terms.

Contingencies
Contingent liabilities are not recognised in the financial statements. They are disclosed unless the possibility of an outflow of resources embodying economic benefits is remote.

A contingent asset is not recognised in the financial statements, but is disclosed when an inflow of economic benefits is probable.

Subsequent events
Post-year-end events that provide additional information about the Company’s position at the balance sheet date or those that indicate the going concern assumption is not appropriate (adjusting events) are reflected in the financial statements. Post-year-end events that are not adjusting events are disclosed in the notes when material.

Use of estimates
The preparation of financial statements requires management to make judgments, estimates and assumptions that affect the reported amounts of revenues, expense, assets and liabilities, and the disclosure of contingent liabilities, at the reporting date. However, uncertainty about these assumptions and estimates could result in outcomes that could require a material adjustment to the carrying amounts of the assets or liabilities affected in the future. The most significant estimates pertain to proved oil and gas reserve volumes and its future development, purchase price allocation, provision for dismantlement as well as impairment and estimates relating to certain oil and gas revenues and expenses. Actual amounts could differ from those estimates and assumptions. Further details are given in notes 3, 15 and 28 to the financial statements.

4.
PRODUCTION SHARING CONTRACTS

The PRC
For production sharing contracts in relation to offshore China (the “China PSC”), the foreign parties to the China PSC (“foreign partners”) are normally required to bear all exploration costs during the exploration period and such exploration costs can be recovered according to the production sharing formula after commercial discoveries are made and production begins.

After the exploration stage, the development and operating costs are funded by the Group and the foreign partners according to their respective percentage of the participating interests.

In general, the Group has the option to take up to 51% participating interests in the development and production of the oil field and/or gas field under the China PSC and may exercise such option after the foreign partners have independently undertaken all the exploration risks and costs, completed all the exploration works and viable commercial discoveries have been made.

After the Group exercises its option to take certain participating interests in a China PSC, the Group accounts for the oil and gas properties according to its participating interest in the China PSC and recognizes its share of development costs, revenues and expenses from operations according to its participating interests in the China PSC. The Group does not account for either the exploration costs incurred by its foreign partners or the foreign partners’ share of development costs, revenues and expenses from operations.

PRODUCTION SHARING CONTRACTS (CONTINUED)

Part of the annual gross production of oil and gas under the China PSC is distributed to the PRC government as a settlement of royalties which are payable pursuant to relevant requirements of the competent authority. The Group and the foreign partners also pay the value-added tax, currently classified as production tax, to the tax bureau at a pre-determined rate. In addition, there is a pre-agreed portion of oil and gas designated to recover all exploration costs, development costs (including the deemed interest) and operating costs incurred by the foreign partners and the Group according to their respective participating interests. Any remaining oil, after the foregoing priority allocations is first distributed to the PRC government as government share oil on a pre-determined ratio calculated by the successive incremental tiers on the basis of the annual gross production, and then distributed to the Group and the foreign partners according to their respective participating interests. As the government share oil is not included in the Group’s interest in the annual production, the net sales revenue of the Group does not include the sales revenue of the government share oil.

The foreign partners have the right either to take possession of their allocable remainder oil for sale in the international market, or to sell their allocable remainder oil in the PRC market according to the relevant laws and regulations of the PRC.

Overseas

In certain countries, the Group and the other partners to the overseas production sharing contracts are required to bear all exploration, development and operating costs according to their respective participating interests. Exploration, development and operating costs which qualify for recovery can be recovered according to the production sharing formula after commercial discoveries are made and production begins.

The Group’s net interest in the production sharing contracts in overseas locations consists of its participating interest in the properties covered under the relevant production sharing contracts, less oil and gas distributed to the local government and/or the domestic market obligation.

In other countries, the Group, as one of the title owners under certain exploration and/or production licenses or permits, is required to bear all exploration, development and operating costs together with other co-owners. Once production occurs, a certain percentage of the annual production or revenue will first be distributed to the local government, which, in most of cases, with the nature of royalty, and the rest of the annual production or revenue will be allocated among the co-owners. Exploration, development and operating costs can be deductible for the purpose of income tax calculation in accordance with local tax regulations.

SEGMENT INFORMATION

Segment information is presented by way of two segment formats: (i) on a primary segment reporting basis, by business segment; and (ii) on a secondary segment reporting basis, by geographical segment.

Intersegment transactions: segment revenue, segment expenses and segment performance include transfers between business segments and between geographical segments. Such transfers are accounted for at cost. Those transfers are eliminated on consolidation.

(a)
Business segments
The Group is organised on a worldwide basis into three major operating segments. The Group is involved in the upstream operating activities of the petroleum industry that comprise independent operations, production sharing contracts with foreign partners and trading business. These segments are determined primarily because senior management makes key operating decisions and assesses the performance of the segments separately. The Group evaluates the performance of each segment based on profit or loss from operations before income taxes.

The following table presents revenue, profit and certain assets, liabilities and expenditure information for the Group’s business segments for the years ended December 31, 2007, 2006 and 2005.

SEGMENT INFORMATION (CONTINUED)

(b)
Geographical segments
The Group mainly engages in the exploration, development and production of crude oil, natural gas and other petroleum products at offshore China. Any activities outside the PRC are mainly conducted in Indonesia, Australia, Nigeria, Canada and Singapore.

In determining the Group’s geographical segments, revenues and results are attributed to the segments based on the location of the Group’s customers, and assets are attributed to the segments based on the location of the Group’s assets. No further analysis of geographical segment information is presented for revenues as over 86% of the Group’s revenues are generated from PRC customers, and revenues generated from customers in other locations are individually less than 10%.

The following table presents certain assets and capital expenditure information for the Group’s geographical segments for the years ended December 31, 2007, 2006 and 2005.

TAX

(i)
Income tax

The Company and its subsidiaries are subject to income taxes on an entity basis on profit arising in or derived from the tax jurisdictions in which the entities of the Group are domiciled and operate. The Company is subject to profits tax at a rate of 17.5% on profits arising in or derived from Hong Kong.

The Company’s subsidiary in Mainland China, CNOOC China Limited, is a wholly-owned foreign enterprise. It is exempt from the 3% local surcharge and is subject to an enterprise income tax rate of 30% under the prevailing tax rules and regulations.

During the 5th Session of the 10th National People’s Congress, which was concluded on March 16, 2007, the PRC Corporate Income Tax Law (the “New CIT Law”) was approved and has become effective on 1 January 2008. The regulations on the implementation of the New CIT Law were approved at the 197th Executive Meeting of the State Council on November 28, 2007. The New CIT Law and the implementation regulations introduce a wide range of changes which include, but not limited to, the unification of the income tax rate for domestic-invested and foreign-invested enterprises at 25%.

As a result of the tax rate change, the Group estimates that the change in the corporate income tax rates has had the following impact on the results and financial position of the Group for the year ended 31 December 2007:
 
 
RMB’000
   
Decrease in income tax expenses
1,019,564
Decrease in deferred tax liabilities
1,019,564

The Company’s subsidiary in Singapore, China Offshore Oil (Singapore) International Pte Ltd., is subject to income tax at rates of 10% and 20% for its oil and gas trading activities and other income generating activities, respectively. The Company’s subsidiaries owning interests in oil and gas properties in Indonesia along the Malacca Strait are subject to corporate and dividend tax at the rate of 44%. According to the current tax treaty between Indonesia and Malaysia, the Company’s subsidiaries owning interests in oil and gas properties in Indonesia are subject to corporate and dividend tax combined at rates ranging from 43.125% to 51.875%. The Company’s subsidiary owning interests in oil and gas properties in the North West Shelf Project (the “NWS Project”) in Australia is subject to income tax at the rate of 30%. All of the Company’s other subsidiaries are not subject to any income taxes in their respective jurisdictions for the years presented.

Certain of the Group’s oil and gas interests in Indonesia are held through Labuan incorporated companies. Companies incorporated in Labuan enjoy certain reduced tax rates provided by the tax treaty between Indonesia and Malaysia. In May 2006, certain proposed amendments to the tax treaty were agreed by the respective ministers of the two countries. According to the proposed amendments, the tax rates will increase from 43.125% to 48% and from 51.875% to 56% respectively. The proposed amendments will need to be ratified by the two countries and will take effect two months after the ratification. It was still uncertain when the ratification will be completed by the two countries as at March 27, 2008.

DIVIDENDS

On August 29, 2007, the board of directors of the Company (the “Board”) declared an interim dividend of HK$0.13 per share (equivalent to approximately RMB0.12 per share) (2006: HK$0.12 per share, 2005: HK$0.05 per share). The interim dividend amounting to HK$5,730,284,000 (equivalent to approximately RMB5,547,488,000) was paid, based on the number of issued shares as at the date of record (2006: approximately RMB5,334,091,000, 2005: approximately RMB2,138,128,000).

The Board has recommended a final dividend of HK$0.17 (equivalent to approximately RMB0.16) (2006: HK$0.14, 2005: HK$0.10) per ordinary share, amounting to HK7,531,445,000 (equivalent to approximately RMB7,052,445,000) for the year ended December 31, 2007 (2006: RMB6,001,819,000, 2005: RMB4,250,391,000). The proposed final dividend for the year is subject to the approval of the Company’s shareholders at the forthcoming annual general meeting.

The payment of future dividends will be determined by the Board, which are based upon, among other things, the Company’s future earnings, capital requirements, financial conditions, future prospects and other factors which the Board may consider relevant. The Company’s ability to pay dividends will also depend on the cash flows determined by the dividends, if any, received by the Company from its subsidiaries and associates.

Cash dividends to the shareholders in Hong Kong will be paid in Hong Kong dollars. Cash dividends to the American Depositary Receipts (the “ADRs”) holders will be paid to the depositary in Hong Kong dollars and will be converted by the depositary into United States dollars and paid to the holders of the ADRs.

Net income per ADS for the three years ended December 31, 2007 has been computed by dividing net income by the number of ADS outstanding. Each ADS represented 100 shares.
 
The calculation of basic earnings per share amounts is based on the profit from ordinary activities attributable to shareholders for the year and the weighted average number of ordinary shares in issue during the year. The calculation of diluted earnings per share amounts is based on the profit for the year, adjusted to reflect the interest expenses and losses recognised on the derivative component of the convertible bonds. The weighted average number of ordinary shares used in the calculation is the ordinary shares in issue during the year, as used in the basic earnings per share calculation, and the weighted average number of ordinary shares assumed to have been issued at no consideration on the deemed exercise or conversion of all the dilutive potential ordinary shares onto ordinary shares.

*
Since the diluted earnings per share amount is increased when taking the convertible bonds into account, the convertible bonds had an anti-dilutive effect on the basic earnings per share for the period and were ignored in the calculation of diluted earnings per share. Therefore, the diluted earnings per share amounts are based on the profit for the year of approximately RMB31,258,299,000, and the weighted average of 43,731,936,869 ordinary shares.

The above listed investments in common stock and liquidity funds which were designated as available-for-sale financial assets have no fixed maturity date and no coupon rate.

The fair values of listed equity investments are based on quoted market prices. The fair values of unlisted investments are based on the prices quoted by fund managers. The Directors believe that the estimated fair values quoted by fund managers, which are recorded in the consolidated balance sheet, and the related changes in fair values, which are recorded in the consolidated balance sheet or income statement, are reasonable, and that they are the most appropriate values at the balance sheet date.

During the year, the gross gains of the Group’s available-for-sale financial assets recognised directly in equity amounted to approximately RMB63,426,000 (2006: RMB60,010,000). In addition, the unrealised gains of the Group’s available-for-sale financial assets of approximately RMB60,010,000 recognised directly in equity in 2006 were transferred from equity to the consolidated income statement during the year (2006: RMB69,069,000 ). The amounts removed from equity to the consolidated income statement were determined on a specific identification basis.

LONG TERM GUARANTEED NOTES

Long term guaranteed notes comprised the following:

(i)
The principal amount of US$500 million of 6.375% guaranteed notes due in 2012 issued by CNOOC Finance (2002) Limited, a wholly-owned subsidiary of the Company. The obligations of CNOOC Finance (2002) Limited in respect of the notes are unconditionally and irrevocably guaranteed by the Company.

(ii)
The principal amount of US$200 million of 4.125% guaranteed notes due in 2013 and the principal amount of US$300 million of 5.500% guaranteed notes due in 2033 issued by CNOOC Finance (2003) Limited, a wholly-owned subsidiary of the Company. The obligations of CNOOC Finance (2003) Limited in respect of the notes are unconditionally and irrevocably guaranteed by the Company.

(iii)
The principal amount of US$1 billion zero coupon guaranteed convertible bonds due in 2009, unconditionally and irrevocably guaranteed by, and convertible into shares of the Company issued by CNOOC Finance (2004) Limited, a wholly-owned subsidiary of the Company, on December 15, 2004. The bonds are convertible from January 15, 2005 onwards at a price of HK$6.075 per share, subject to adjustments. The conversion price was adjusted to HK$5.97, HK$5.90 and HK$5.79 per share on June 7, 2005, June 7, 2006 and June 7, 2007, respectively, as a result of the declaration of the dividends for 2004, 2005 and 2006 by the Company. Unless previously redeemed, converted or purchased and cancelled, the bonds will be redeemed on the maturity date at 105.114% of the principal amount. CNOOC Finance (2004) Limited has an early redemption option at any time after December 15, 2007 (subject to certain criteria) and a cash settlement option to pay cash in lieu of delivering shares when the bondholders exercise their conversion right. The bondholders also have an early redemption option to require CNOOC Finance (2004) Limited to redeem all or part of the bonds on December 15, 2007 at an early redemption amount of 103.038% of the principal amount.

CNOOC Finance (2004) Limited renounced its cash settlement option by way of a supplemental trust deed dated July 31, 2007 entered into amongst the Company, CNOOC Finance (2004) Limited and BNY Corporate Trustee Services Limited. As such, the derivative component of the convertible bonds is no longer a liability and was transferred to equity.

During the year, convertible bonds with a face value of US$725,848,000 were converted into new shares of the Company. As at December 31, 2007, US$274,151,000 of convertible bonds were outstanding.

For conversion before the renunciation of cash settlement option, the bifurcated derivative component was marked to market through earnings up to the conversion date. The host bond was accreted and any deferred issuance costs was amortized up to the conversion date as if bond were to remain outstanding for its contractual life. The accreted value of the host bond and the marked-to-market value of derivative component were then reclassified into equity. Upon renunciation of the cash settlement option, the entire derivative component was marked to market and reclassified into equity. Subsequent conversions were accounted for in the same way but without considering the derivative component.

On February 21, 2008, CNOOC Finance (2004) Limited extinguished all the outstanding convertible bonds by exercising an early redemption option. The withdrawal of delisting of the convertible bonds on The Stock Exchange of Hong Kong Limited was effective at the close of business on March 6, 2008. The Group currently has no convertible bond liability.

There is no default during the year of principal, interest or redemption term of the long term guaranteed notes.

RELATED PARTY TRANSACTIONS

The majority of the Group’s business activities are conducted with state-owned enterprises (including CNOOC and its associates). As the Group is controlled by CNOOC, transactions with CNOOC and its associates are disclosed as related party transactions. The Group considers that transactions with other state-owned enterprises (other than CNOOC and its associates) are in the ordinary course of business and there are no indicators that the Group influenced, or was influenced by, those state-owned enterprises. Accordingly, the Group has not disclosed such transactions with other state-owned enterprises (other than CNOOC and its associates) as related party transactions.

In order to present a more coherent, logical and understandable picture to shareholders, and also to enable the Company to monitor the status of its connected transactions as defined under the Rules Governing the Listing of Securities on The Stock Exchange of Hong Kong Limited (the “Listing Rules”) more effectively, the Company has adopted a new categorisation for its related party/continuing connected transactions with CNOOC and/or its associates. On December 8, 2005, the Company entered into three comprehensive framework agreements with each of CNOOC, China Oilfield Services Limited (“COSL”) and Offshore Oil Engineering Co., Ltd (“CNOOC Engineering”) respectively for the provision (1) by the Group to CNOOC and/or its associates and (2) by CNOOC and/or its associates to the Group, of a range of products and services which may be required and requested from time to time by either party and/or its associates in respect of the new categories of related party/continuing connected transactions. The term of each of the comprehensive framework agreements is for a period of two years from January 1, 2006. The new categorisation and caps for each category of related party/continuing connected transactions as approved by the independent shareholders of the Company on  December 31, 2005 applicable to the Company for the period from January 1, 2006 to December 31, 2007 are as follows:

 
Provision of exploration, oil and gas development, oil and gas production as well as marketing, management and ancillary services by CNOOC and/or its associates to the Group;

 
Provision of management, technical, facilities and ancillary services, including the supply of materials from the Group to CNOOC and/or its associates; and

 
Sales of petroleum and natural gas products by the Group to CNOOC and/or its associates.

On December 6, 2007, the independent shareholders of the Company approved the renewal of the continuing connected transactions for the next three years (from January 1, 2008 to December 31, 2010) including the relevant proposed caps. The revised cap for the provision of exploration and support services by CNOOC and/or its associates to the Group for the year ended December 31, 2007 was also approved.

Since the establishment of CNOOC, certain associates of CNOOC specialised in exploration, oil and gas development, oil and gas production, as well as marketing, management and ancillary services to the Group through bidding process. The Group will continue to use these services provided by the associates of CNOOC, including but not limited to COSL, CNOOC Engineering and CNOOC Oil Base Group Limited (“COBGL”). CNOOC also provides certain of these services from time to time. The services provided by CNOOC and/or its associates are set out below.

In addition to providing various services to the Group, CNOOC and/or its associates may also utilise various types of management, technical, facilities and ancillary services, including the supply of materials provided by the Group from time to time. The pricing for such services will be determined based on the same pricing principles applicable to transactions relating to services provided by CNOOC and/or its associates to the Group under paragraphs (a) to (d) above, which will be negotiated and agreed on normal commercial terms between the parties.

(b)
Long term sales of natural gas and liquefied natural gas
The Group sells natural gas to CNOOC and/or its associates which engage in the downstream petroleum businesses at state-prescribed prices or local, national or international market prices and on normal commercial terms, which is subject to adjustment in accordance with movements in international oil prices as well as other factors such as the term of the sales agreement and the length of the relevant pipeline. Due to the size of investment and the fact that sales are usually made to markets proximate to the production site, and that purchasers tend to utilise the natural gas products in areas close to the production sites, and in order to ensure the return on investment from the production of natural gas, the Group will usually enter into long term sales contracts with a term of 15 to 20 years. It is market practice for the term of the sales contract to be determined based on the estimated reserves and production profile of the relevant gas fields. The Group has also invested and acquired interests in liquefied natural gas related upstream projects in Tangguh, Indonesia and the North West Shelf, Australia. It is also envisaged that from time to time the Group may sell liquefied natural gas explored from these gas reserves mentioned above and other gas reserves in which the Group may invest in the future to CNOOC and/or its associates.

For the year ended December 31, 2007, the total sales of petroleum and natural gas products by the Group to CNOOC and/or its associates amounted to approximately RMB40,053,593,000 (2006: RMB35,493,341,000, 2005: RMB26,576,247,000). Among such sales, the sales under long term sales contracts for natural gas and liquefied natural gas amounted to approximately RMB1,524,731,000 (2006: RMB1,247,561,000, 2005: RMB588,297,000), and the sales under the sales contracts of petroleum and natural gas products amounted to approximately RMB38,528,862,000 (2006: RMB34,245,780,000, 2005: RMB25,987,950,000).

(iv)
Transactions with CNOOC Finance Corporation Limited

In addition to the above related party transactions, the Company also entered into a framework agreement (the “Framework Agreement”) with CNOOC Finance Corporation Limited (“CNOOC Finance”) on April 8, 2004. Under the Framework Agreement, the Group utilises the financial services provided by CNOOC Finance, a 31.8% owned associate of the Company and also a subsidiary of CNOOC. Such services include placing of the Group’s cash deposits with CNOOC Finance, the settlement services for transactions between the Group and other entities including CNOOC and its associates and the provision of loans. The charges including the interest rates and other fees levied by CNOOC Finance for its financial services to the Group are based on the pricing policies of CNOOC Finance, which are subject to the People’s Bank of China guidelines, as well as guidelines published by PRC self-regulatory bodies, such as China National Association of Finance Companies. Based on these guidelines, CNOOC Finance has limited discretion in setting its prices.

As the waiver for the deposit services provided by CNOOC Finance to the Group with the cap of RMB6.8 billion which expired on April 7, 2007 was not renewed, the Group has only continued to use the financial services provided by CNOOC Finance to the extent that they are exempted from the reporting, announcement and independent shareholders’ approval requirements under the Listing Rules since then. For the year ended December 31, 2007, the interest income earned from deposits in CNOOC Finance amounted to approximately RMB26,875,000 (2006: RMB65,499,000, 2005: RMB58,076,000).

PROVISION FOR DISMANTLEMENT

Provision for dismantlement represents the estimated costs of dismantling offshore oil platforms and abandoning oil and gas properties. The provision for dismantlement has been classified under long term liabilities. The associated cost is capitalised and the liability is discounted and an accretion expense is recognised using the credit-adjusted risk-free interest rate in effect when the liability is initially recognised. The current year’s income statement charge represents the amortisation charge on the dismantlement liabilities capitalised in accordance with HKAS 37 and is included in the accumulated depreciation, depletion and amortisation of property, plant and equipment in note 15 to the financial statements.

SHARE CAPITAL (CONTINUED)

Share option schemes (continued)
The fair value of the share options granted during the year was HK$148,277,400 (2006: HK$126,795,127, 2005:HK$103,881,616) and the Group recognised equity-settled share option expenses of approximately RMB98,237,000 (2006: RMB75,768,000; 2005: RMB29,123,000) during the year.

The fair value of equity-settled share options granted during the year was estimated as at the date of grant, using the Black-Scholes model, taking into account the terms and conditions upon which the options were granted.

The following table lists the assumptions to the model used:

The expected life of the options is based on the historical data and is not necessarily indicative of the exercise patterns that may occur. The expected volatility reflects the assumption that the historical volatility is indicative of future trends, which may also not necessarily be the actual outcome. No other feature of the options granted was incorporated into the measurement of fair value. Any changes to the above assumptions may affect the estimation of the fair value of the option.

No share option had been cancelled during the year ended December 31, 2007.

At the date of approval of these financial statements, the share options outstanding under these share option schemes represented approximately 0.69% of the Company’s shares in issue as at that date. The aggregate intrinsic value and the weighted average remaining contractual life of share options outstanding at the end of the year is RMB2,349,754,052 and 7.50 years respectively (2006: RMB791,478,699 and 7.76 years respectively). The aggregate intrinsic value and the weighted average remaining contractual life of share options exercisable at the end of the year is RMB1,407,312,303 and 6.12 years respectively (2006: RMB527,965,205 and 6.30 years respectively). The exercise in full of the outstanding share options would, under the present capital structure of the Company, result in the issue of 303,795,233 additional ordinary shares of the Company and additional share capital of RMB5,689,356 and share premium of RMB1,421,132,027.

RESERVES

According to the laws and regulations of the PRC and the articles of association of CNOOC China Limited, CNOOC China Limited is required to provide for certain statutory funds, namely, the general reserve fund and staff and workers’ bonus and welfare fund, which are appropriated from net profit (after making good losses from previous years), but before dividend distribution.

CNOOC China Limited is required to allocate at least 10% of its net profit as reported in accordance with the generally accepted accounting principles in the PRC (“PRC GAAP”) to the general reserve fund until the balance of such fund has reached 50% of its registered capital. The general reserve fund can only be used, upon approval by the relevant authority, to offset against accumulated losses or to increase capital.

Appropriation to the staff and workers’ bonus and welfare fund, which is determined at the discretion of the board of directors of CNOOC China Limited, is expensed as incurred under Hong Kong GAAP. The staff and workers’ bonus and welfare fund can only be used for special bonuses or collective welfare of employees.

As at December 31, 2007, the general reserve fund amounted to RMB10,000,000,000 (2006: RMB9,460,631,000), representing 50.0% (2006: 47.3%) of the total registered capital of CNOOC China Limited.

Included in retained earnings is an amount of approximately RMB1,774,109,000 (2006: RMB1,183,515,000), being the retained earnings attributable to associates.

The Company’s ability to distribute dividends will largely depend on the dividends it receives from its subsidiaries. The dividends distributable by the Company’s subsidiaries to the Company are determined in accordance with the relevant accounting principles required by the local authorities. As at December 31, 2007, the aggregate amount of the Group’s retained earnings available for distribution to the Company’s shareholders amounted to approximately RMB56,774,492,000 (2006: RMB40,013,439,000).

COMMITMENTS (CONTINUED)

(iii)
Contingent liabilities

On January 8, 2006, the Company signed a definitive agreement with South Atlantic Petroleum Limited (“SAPETRO”) to acquire a 45% working interest in the Offshore Oil Mining Lease 130 (“OML130”) in Nigeria (the “OML130 Transaction”) and the OML130 Transaction was completed on April 20, 2006. The OML130 project is still in the exploration and development phase.

In 2007, a local tax office in Nigeria (the “Nigerian Local Tax Office”) conducted a tax audit on SAPETRO. According to the preliminary tax audit results, the Nigerian Local Tax Office has raised a disagreement in the tax filings made for the OML130 Transaction. The final tax audit results might affect the acquisition cost of the Company for the OML130 Transaction.

The tax audit assessment made by the Nigerian Local Tax Office has been contested by the Company in accordance with Nigerian laws. After seeking legal and tax advice, the Company’s management believes that the Company has reasonable grounds in making the contest. Consequently, no provision has been made for any expenses and/or adjustment to the acquisition cost of OML 130 which might arise as a result of the dispute.

FINANCIAL INSTRUMENTS

(a)
Currency swap contracts

The Group had a currency swap contract with a financial institution to sell United States dollars in exchange for Japanese Yen in order to hedge against future repayments of certain Japanese Yen denominated loans. The hedged Japanese Yen loans bore interest at a fixed rate of 4.5% per annum. The interest rate stipulated in the swap contract for the United States dollars was the floating LIBOR rate. The Japanese Yen loans were fully paid and the currency swap contract had expired as at December 31, 2007.

(b)
Fair value of financial instruments

The carrying values of the Group’s cash and cash equivalents, time deposits, current available-for-sale investments, accounts receivable, other current assets, accounts payable, other payables and balances with related companies approximated to their fair values at the balance sheet date due to the short maturity of these instruments.

The estimated fair value of the Group’s long term bank loans based on current market interest rates was approximately RMB3,175,413,000 as at December 31, 2007 (2006: RMB2,450,147,000), which was the present value of the loans’ future cash flows discounted by the interest rates as at December 31, 2007. The fair value of the floating interest rate loan equalled to the carrying amount as at December 31, 2007.

The estimated fair value of the Group’s long term guaranteed notes based on current market interest rates was approximately RMB11,932,142,000 as at December 31, 2007 (2006: RMB17,735,947,000), which was calculated based on the market price as at  December 31,2007.

CONCENTRATION OF RISKS

The Group’s principal financial instruments, other than derivatives, comprise bank loans, convertible bonds, long term guaranteed notes, available-for-sale financial assets, cash and short term deposits. The main purpose of these financial instruments is to raise finance for the Group’s operations. The Group has various other financial assets and liabilities such as accounts receivable and accounts payable, which arise directly from its operations.

(a)
Credit risk
The carrying amount of the Group’s cash and cash equivalents, time deposits, liquidity funds and bond investments, accounts receivable and other receivables, and amounts due from related parties and other current assets except for prepayments represents the Group’s maximum exposure to credit risk in relation to its financial assets.

The majority of the Group’s accounts receivable is related to sales of oil and natural gas to third party customers. The Group performs ongoing credit evaluations of the customers’ financial condition and generally does not require collateral on accounts receivable. The Group made impairment on doubtful receivables and actual losses have been within management’s expectation.

Since the Group trades only with recognised and creditworthy third parties, there is no requirement for collateral. Concentrations of credit risk are managed by customer/counterparty and by geographical region. At the balance sheet date, the Group has certain concentrations of credit risk as 52% (2006: 31%) and 83% (2006: 56%) of the Group’s trade receivables were due from the Group’s largest customer and the five largest customers, respectively.

No other financial assets carry a significant exposure to credit risk.

CONCENTRATION OF RISKS (CONTINUED)

(b)        Oil and gas price risk
As our oil prices are mainly determined by reference to the oil prices in international markets, changes in international oil prices have a large impact on us. Unstable and high volatility of international oil prices will have a significant effect on our net sales and net profits.

(c)        Currency risk
Substantially all of the Group’s oil and gas sales are denominated in Renminbi and United States dollar (“US dollars”). In the past decade, the PRC government’s policies of maintaining a stable exchange rate and China’s ample foreign reserves have contributed to the stability of the Renminbi. Starting from July 21, 2005, China reformed the exchange rate regime by moving into a managed floating exchange rate regime based on market supply and demand with reference to a basket of currencies. Renminbi would no longer be pegged to the US dollars. From that day to December 28, 2007 (the last working day in 2007), Renminbi has appreciated by approximately 13.31% against US dollars.

The management has assessed the Group’s exposure to foreign currency risks by using a sensitivity analysis on the change in foreign exchange rate of US dollars, to which the Group is mainly exposed to as at December 31, 2006 and 2007. Based on management’s assessment, a reasonably possible change in foreign exchange rate of US dollar of 5 percent is used, and assuming that had the change in foreign currency rates had occurred at 31 December, the exposures of the Group’s results of operations, monetary assets and liabilities and investment in its foreign subsidiaries were less than 0.10% of the profit of the year.

CONCENTRATION OF RISKS (CONTINUED)

(c)        Currency risk (continued)
The appreciation of Renminbi against US dollars may have the following impact on the Group. On one hand, since the benchmark oil and gas prices are usually in US dollars, the Group’s oil and gas sales may decrease due to the depreciation of US dollars against Renminbi. On the other hand, the depreciation of US dollars against Renminbi will also decrease the Group’s costs for imported equipment and materials, most of which are denominated in US dollars. In addition, the debt repayment by the Group will decrease since approximately 96% of the Group’s debts are also denominated in US dollars.

(d)        Interest rate risk
As of the end of 2007, the interest rates for 78% of the Group’s debts were fixed. The term of the weighted average balance was approximately 8.5 years. The fixed interest rate can reduce the volatility of financial cost and is considered to be favorable under the environment of rising interest rate hike.

(e)        Business risk
The major operations of the Group are conducted in the PRC, Indonesia, Africa and Australia and accordingly are subject to special considerations and significant risks not typically associated with investments in equity securities of the United States of America and Western European companies. These include risks associated with, among others, the oil and gas industry, the political, economic and legal environments, influence of the national authorities over price setting and competition in the industry.

(f)        Liquidity risk
The Group manages its liquidity risk by regularly monitoring its liquidity requirements and its compliance with debt covenants, to ensure that it maintains sufficient cash and cash equivalents, and readily realisable available-for-sale financial assets, and adequate time deposits to meet its liquidity requirements in the short and long term. In addition, bank facilities have been put in place for contingency purposes.

(g)        Concentration of customers
A substantial portion of the oil and gas sales of the Group is made to a small number of customers on an open account basis. Details of the sales to these customers are as follows:

(h)       Capital management

The primary objective of the Group’s capital management is to safeguard the Group’s ability to continue as a going concern and to maintain healthy capital ratios in order to support its business and maximize shareholder value.

The Group manages its capital structure and makes adjustments to it, in light of changes in economic conditions. To maintain or adjust the capital structure, the Group may return capital to shareholders, raise new debt or issue new shares. No changes were made in the objectives, policies or processes during the years end December 31, 2007 and December 31, 2006.

The Group monitors capital on the basis of the debt to capitalisation ratio, which is calculated as interest-bearing debts divided by total capital (equity attributable to equity holders plus interest bearing debts).

SUBSEQUENT EVENTS

The Company and certain of its subsidiaries were the named defendants (the “Defendants”) in a case brought by a subsidiary of Talisman Energy Inc. (the “Plaintiff”) which is a partner of a joint operating agreement (the “JOA”) relating to the Southeast Sumatra production sharing contract working area in Indonesia. The Plaintiff was claiming rights under the JOA to demand an interest in the Tangguh LNG Project. The Defendants have fully settled the litigation with the Plaintiff and Talisman Energy Inc. by reaching an agreement to sell to Talisman Energy Inc. a 3.05691% working interest in the Tangguh LNG Project for a consideration of US$212.5 million. The transaction was completed through the equity transfer of an indirect subsidiary of the Company and became effective on January 1, 2008 (Hong Kong time). The Company through its subsidiary continues to hold a 13.89997% working interest in the Tangguh LNG Project after the sale.

Accordingly, the related property, plant and equipment are classified as a non-current asset classified as held for sale and the related long term bank loan is classified as liabilities directly associated with non-current asset classified as held for sale as at December 31, 2007.

39.
SIGNIFICANT DIFFERENCES BETWEEN HONG KONG GAAP AND US GENERALLY ACCEPTED ACCOUNTING PRINCIPLES (“US GAAP”)

(a)        Impairment of long-lived assets
Under Hong Kong GAAP, impairment charges are recognised when a long-lived asset’s carrying amount exceeds the higher of an asset’s fair value less costs to sell and value in use, which incorporates discounting the asset’s estimated future cash flows.

Under US GAAP, long-lived assets are assessed for possible impairment in accordance with SFAS No. 144 Accounting for the Impairment or Disposal of Long-lived Assets. SFAS No. 144 requires the Group to (a) recognise an impairment loss only if the carrying amount of a long-lived asset is not recoverable from its undiscounted cash flows and (b) measure an impairment loss as the difference between the carrying amount and the fair value of the asset. SFAS No. 144 requires that a long-lived asset to be abandoned, exchanged for a similar productive asset, or distributed to owners in a spin-off be considered as held and used until it is disposed of.

SFAS No. 144 also requires the Group to assess the need for an impairment of capitalised costs of proved oil and gas properties and the costs of wells and related equipment and facilities on a property-by-property basis. If an impairment is indicated based on undiscounted expected future cash flows, then an impairment is recognised to the extent that net capitalised costs exceed the estimated fair value of a property. The fair value of the property is estimated by the Group using the present value of future cash flows. The impairment is determined based on the difference between the carrying value of the assets and the present value of future cash flows. It is reasonably possible that a change in reserve or price estimates could occur in the near term and adversely impact management’s estimate of future cash flows and consequently the carrying value of properties.

SIGNIFICANT DIFFERENCES BETWEEN HONG KONG GAAP AND US GAAP (CONTINUED)

(a)       Impairment of long-lived assets (continued)
In addition, under Hong Kong GAAP, a subsequent increase in the recoverable amount of an asset (other than goodwill and available-for-sale equity investments) is reversed to the income statement to the extent that an impairment loss on the same asset was previously recognised as an expense when the circumstances and events that led to the write-down or write-off cease to exist. The reversal is reduced by the amount that would have been recognised as depreciation had the write-down or write-off not occurred. Under US GAAP, an impairment loss establishes a new cost basis for the impaired asset and the new cost basis should not be adjusted subsequently other than for further impairment losses.

For the year ended December 31, 2007, an impairment of approximately RMB613,505,000 related to an aged oil field was recognised under both Hong Kong GAAP and US GAAP. For the year ended December 31, 2006, an impairment of approximately RMB252,357,000 was recognised under Hong Kong GAAP and no impairment was recognised under US GAAP because the carrying amounts of certain oil and gas fields exceed their fair values estimated using discounted future cash flows even though the undiscounted future cash flows of these oil and gas fields exceed their respective carrying amounts. As a result, additional depreciation of approximately RMB34,080,000 was recognised under US GAAP.

(b)        Accounting for convertible bonds
With effect from January 1, 2005, under HKAS 32 Financial Instruments: Disclosure and Presentation, financial instruments with cash settlement options and other derivative components need to be bifurcated into a debt component and a derivative component. The derivative component is marked to market at each balance sheet date and the differences are charged/credited to the consolidated income statement. However, with the renunciation of the cash settlement option in relation to the Group’s convertible bonds on July 27, 2007, under Hong Kong GAAP, the derivative component is transferred to equity. As such, no further mark-to-market of the derivative component is required going forward. There was no impact on the debt component, which has been stated at amortised cost.

Under US GAAP, convertible bonds are subject to different rules on the bifurcation of the debt and derivative components. According to SFAS No. 133 Implementation Issue No. C8, the renunciation of the cash settlement options does not cause the derivative component to be reclassified to an equity component, therefore the derivative component is still marked to market at each balance sheet date and the differences will be charged/credited to the consolidated income statement. The debt component is stated at amortised cost.

The Company considered whether the convertible bonds contain embedded derivative features which warrant separate accounting under the guidance provided in SFAS No. 133. To the extent that the embedded derivatives are determined to exist, the embedded derivatives are bifurcated as a single, compound derivative and are accounted for in accordance with SFAS No. 133. The Company bifurcated its embedded derivatives at fair value and determined the initial carrying value assigned to the host contract as the difference between the basis of the hybrid instrument and the fair value of the embedded derivatives, resulting in a discount attributed to the host bond contract. The host bond contract is then accreted from the initial amount to the maturity amount over the period from the date of issuance to the maturity date using the effective interest method.

The embedded derivative features within the convertible bonds that would individually warrant separate accounting as a derivative instrument under SFAS No. 133 are bundled together as a single, compound embedded derivative instrument that is bifurcated and accounted for separately from the host contract under SFAS No. 133. The Company used the binominal tree valuation model to value the compound embedded derivative features both initially and at each reporting period to record the changes in fair value of the derivative instruments.

SIGNIFICANT DIFFERENCES BETWEEN HONG KONG GAAP AND US GAAP (CONTINUED)

(b)       Accounting for convertible bonds (continued)
Instruments with potential embedded derivative features are evaluated at inception to determine whether such features meet the definition of a derivative. The embedded derivative feature would be separated from the host contract and accounted for as a derivative instrument only if all of the following conditions are met:

(i)
the economic characteristics and risks of the embedded derivative instrument are not clearly and closely related to the economic characteristics and risks of the host contract;

(ii)
the hybrid instrument that embodies both the embedded derivative instrument and the host contract is not re-measured at fair value; and

(iii)
a separate instrument with the same terms as the embedded derivative instrument would meet the definition of a derivative as described in SFAS No. 133.

The Group’s convertible bonds include the following embedded derivative features that warrant separate accounting as a single, compound embedded derivative instrument under SFAS No. 133:

(i)
The bondholders’ right to convert the convertible bonds into the Company’s shares at specific price;

(ii)
Prior to the renunciation of cash settlement option, upon exercise of the conversion right by the bondholders of the convertible bonds, the Company has the option to settle the exercise of the conversion right in cash; and

(iii)
The convertible bonds are denominated in US dollars and are convertible into the Company’s share denominated into Hong Kong dollars using a fixed exchange rate of US$1 to HK$7.77.

(c)        Use of estimates in the preparation of financial statements
The preparation of financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. The most significant estimates pertain to proved oil and gas reserve volumes, the future development cost and provision for dismantlement as well as estimates relating to certain oil and gas revenues and expenses. Actual amounts could differ from those estimates and assumptions.

(d)        Segment reporting
The Group’s segment information is based on the segmental operating results regularly reviewed by the Group’s chief operating decision maker. The accounting policies used are the same as those used in the preparation of the Group’s consolidated Hong Kong GAAP financial statements.

SIGNIFICANT DIFFERENCES BETWEEN HONG KONG GAAP AND US GAAP (CONTINUED)

(e)        Income tax
The Group completed the acquisition of certain oil and gas interests in Nigeria in 2006. The oil and gas properties are still under exploration and development stage.

According to HKAS 12 “Income Taxes”, no deferred income tax liability is recognised for an asset acquisition. However, under US GAAP, a deferred income tax liability is recognised in accordance with EITF 98-11 “Accounting for Acquired Temporary Differences in Certain Purchase Transactions that are not Accounted for as Business Combinations”. Accordingly, both the property, plant and equipment and deferred tax liabilities related to OML130 are increased by RMB16,014,569,000 under US GAAP. The difference in accounting treatment has had no impact on the net equity reported under US GAAP.

(f)        Provision for dismantlement
Hong Kong GAAP requires the provision for dismantlement to be recorded for a present obligation no matter whether the obligation is legal or constructive. The associated cost is capitalised and the liability is discounted and accretion expense is recognised using a pre-tax rate that reflects current market assessments of the time value of money and the risks specific to the liability. In cases of remeasuring the provision for dismantlement of oil and gas properties, the Group shall use such a discount rate as mentioned above no matter whether future cash flows would move upward or downward. HK(IFRIC)-Int 1 requires that adjustments arising from changes in the estimated cash flows or the current discount rate should be added to or deducted from the cost of the related asset and liability.

Under US GAAP, SFAS No. 143 requires that the fair value of a liability for an asset retirement obligation to be recognised in the period in which it is incurred if a reasonable estimate of fair value can be made. The associated asset retirement costs are capitalised as part of the carrying amount of the long-lived assets. Further, under SFAS No. 143, the liability is discounted and accretion expense is recognised using the credit-adjusted risk-free interest rate in effect when the liability is initially recognised. If the Group remeasures the provision for dismantlement of oil and gas properties, upward revisions in the amount of undiscounted estimated cash flows shall be discounted using the current credit-adjusted risk-free rate; downward revisions in the amount of undiscounted estimated cash flows shall be discounted using the credit-adjusted risk-free rate that existed when the original liability was recognised. In cases that changes occur to the discount rate, the Group shall apply the original discount rate used to initially measure the dismantlement costs, rather than remeasuring the liability for changes in the discount rate. There were no differences between the amounts under Hong Kong GAAP and US GAAP for the periods presented.

(g)        Income tax rates
Under Hong Kong GAAP, HKAS 12 required the application of tax rates that have been enacted or substantively enacted by the balance sheet date.

Under US GAAP, SFAS No. 109 requires that a deferred tax liability or asset shall be measured using the enacted tax rates expected to apply to taxable income in the periods in which the deferred tax liability or asset is expected to be settled or realised.

There were no differences in the tax rates used for both Hong Kong GAAP and US GAAP for the periods presented.

SIGNIFICANT DIFFERENCES BETWEEN HONG KONG GAAP AND US GAAP (CONTINUED)

(h)       Accounting for uncertainty in income taxes
Under US GAAP, FIN 48 clarifies the accounting for income taxes by prescribing the minimum recognition threshold a tax position is required to meet before being recognised in the financial statements. It provides guidance on derecognition, measurement, classification, interest and penalties, accounting in interim periods, disclosure and transition. The adoption of FIN 48 by the Company on January 1, 2007 had no significant impact on its financial position and result of operations.

However, under HK GAAP, there are no established standards specifically dealing with accounting for uncertainty in income taxes except for HKAS 37 Provisions, Contingent Liabilities and Contingent Assets that applies to all contingencies.

The RMB444,719,000 of suspended well costs capitalised for a period greater than one year as at December 31, 2007 represents six exploratory wells in four projects. RMB48,162,000 is related to wells drilled in 2005 and 2006 for two projects that had drilling activities under way that were firmly planned for the near future, and RMB396,557,000 is related to wells drilled in 2005 and 2006 for two projects, for which additional drilling was not deemed necessary, because the presence of hydrocarbons had already been established, and other activities were in process to enable a future decision on project development.

SIGNIFICANT DIFFERENCES BETWEEN HONG KONG GAAP AND US GAAP  (CONTINUED)

Impact of recently issued accounting standards

In December 2007, the Financial Accounting Standards Board (“FASB”) issued SFAS No. 141 (revised 2007) “Business Combinations”(“SFAS No.141(R)”), which requires the acquiring entity in a business combination to recognize the assets acquired, the liabilities assumed, and any noncontrolling interest in the acquiree at the acquisition date to be measured at their respective fair values. It also requires acquisition-related costs, as well as restructuring costs the acquirer expects to incur for which it is not obligated at acquisition date, to be recorded against income rather than included in purchase-price determination. Under this statement, contingent arrangements shall be recognised at their acquisition-date fair values, with subsequent changes in fair value generally reflected in income. SFAS No. 141(R) will become effective for business combinations for which the acquisition date is on or after January 1, 2009. We are currently evaluating the potential impact of SFAS No. 141(R) on our financial position and results of operations.
 
In December 2007, FASB issued SFAS No. 160 “Noncontrolling Interests in Consolidated Financial Statements—an amendment of ARB No. 51”, which establishes accounting and reporting standards for the noncontrolling interest in a subsidiary and for the deconsolidation of a subsidiary. It will become effective for the accounting period beginning on or after January 1, 2009. We are currently evaluating the potential impact of SFAS No. 160 on our financial position and results of operations.
 
In March 2008, FASB issued SFAS No. 161 “Disclosures about Derivative Instruments and Hedging Activities—an amendment of FASB Statement No. 133”, which amends and expands the disclosure requirements of SFAS No.133, Accounting for Derivative Instruments and Hedging Activities. It requires qualitative disclosures about objectives and strategies for using derivatives, quantitative disclosures about fair value amounts of and gains and losses on derivative instruments, and disclosures about credit-risk-related contingent features in derivative agreements. It will become effective for financial statements issued for accounting period beginning on or after January 1, 2009. As our existing accounting policy for derivatives complies with the requirements of this Statement, we do not believe the adoption of SFAS No. 161 will have a material effect on our financial statements disclosures.

SUPPLEMENTARY INFORMATION ON OIL AND GAS PRODUCING ACTIVITIES
(UNAUDITED)
(All amounts expressed in Renminbi unless otherwise stated)
 
The following disclosures are included in accordance with the United States Statement of Financial Accounting Standards No. 69, “Disclosures about Oil and Gas Producing Activities”. The disclosures are categorised by the geographical areas in which the Group conducts oil and gas activities. Except for PRC and Indonesia, the information on the other geographical areas, such as Australia, Myanmar, Morocco and Nigeria etc., are combined in the following disclosures as “Others”, among which all the other projects are still in joint study, exploration or development stage except that the North West Shelf Project in Australia is in production stage.

(a)
Reserve Quantity Information
Crude oil and natural gas reserve estimates are determined through analysis of geological and engineering data which appear, with reasonable certainty, to be recoverable at commercial rates in the future from known oil and natural gas reservoirs under existing economic and operating conditions.

Estimates of crude oil and natural gas reserves have been made by independent engineers. The Group’s net proved reserves consist of its percentage interest in reserves, comprised of a 100% interest in its independent oil and gas properties and its participating interest in the properties covered under the production sharing contracts in PRC, less (i) an adjustment for the Group’s share of royalties payable by the Group to the PRC government and the Group’s participating interest in share oil payable to the PRC government under the production sharing contracts, and less (ii) an adjustment for production allocable to foreign partners under the PRC production sharing contracts as reimbursement for exploration expenses attributable to the Group’s participating interest, and plus (a) its participating interest in the properties in Australia and Nigeria; and (b) the participating interest in the properties covered under the production sharing contracts in Indonesia less an adjustment of share oil attributable to the Indonesian government and the domestic market obligation.

The Company determines its net entitlement oil and gas reserves under production sharing contracts using the economic interest method.

Standardised Measure of Discounted Future Net Cash Flows and Changes Therein
In calculating the standardised measure of discounted future net cash flows, year-end constant price and cost assumptions were applied to the Group’s estimated annual future production from proved reserves to determine future cash inflows. Year end average realised oil prices used in the estimation of proved reserves and calculation of the standardised measure were US$86 as at  December 31, 2007 (2006: US$51; 2005; US$48). Future development costs are estimated based upon constant price assumptions and assume the continuation of existing economic, operating and regulatory conditions. Future income taxes are calculated by applying the year-end statutory rate to estimate future pre-tax cash flows after provision for the tax cost of the oil and natural gas properties based upon existing laws and regulations. The discount was computed by application of a 10% discount factor to the estimated future net cash flows.

Management believes that this information does not represent the fair market value of the oil and natural gas reserves or the present value of estimated cash flows since no economic value is attributed to potential reserves, the use of a 10% discount rate is arbitrary, and prices change constantly from year-end levels.

Present value of estimated future net cash flows:
