                                 ANNOUNCEMENT

-----------------------------------------------------------------------------
The Company hereby announces that Typhoon Chan Chu did not cause any oil
spills or casualty, as a result of the Company's continuous focus on health,
safety and environment.
-----------------------------------------------------------------------------

CNOOC Limited (the "Company") hereby announces that Typhoon Chan Chu did not
cause any oil spills or casualty, as a result of the Company's continuous
focus on health, safety and environment.

The first typhoon this year, Typhoon Chan Chu, suddenly turned in right angle
after arriving in Eastern South China Sea. The centre of the typhoon attacked
Liuhua Oil Field directly and the wind force of its centre exceeded the
designed typhoon-combating capacity to stand the severest typhoon attack in a
century. The Company closely monitored Typhoon Chan Chu when it arrived and
completed the prevention and evacuation measures in a timely and organised
manner. The Company mobilised 144 flights to evacuate over 3,840 offshore
personnel from twenty-five platforms and FPSO across 17 oil fields in the
Eastern South China Sea, including the staff of our contractors on offshore
vessels, to ensure a safe and steady evacuation and resumption of production.
Before evacuation, the Company adopted typhoon prevention measures including
well closure in relation to the relevant production facilities.

As a result of sufficient prevention and evacuation measures, Typhoon Chan Chu
did not cause any oil spills or casualty.

After the landing of Typhoon Chan Chu, the Company completed comprehensive
examination of all of its oil fields in the area. None of the production
facilities, except the Liuhua Oil Field, experienced any damages and have
resumed production. During the Company's examination, it was discovered that
part of the production facilities in the Liuhua Oil Field was damaged. The
Company has moblilized various service companies, including underwater
services and examination contractors to conduct an underwater examination so
as to determine the damage caused. Based on the results of examination
conducted so far, seven anchors and three risers are shown to have split and
broken.

The Company is arranging to tug the FPSO to safe areas. Meanwhile, the Company
is also arranging for a team including designers, manufactures, installation
contractors to prepare a plan for the resumption of the production facility.
Before Typhoon Chan Chu arrived, the daily production of the Liuhua Oil Field
was 22,000 barrels of oil per day.

As at the date of this announcement, the Board comprises the following:

             No Casualties or Oil Spillage Due to Typhoon Chan Chu

(Hong Kong, May 25, 2006) - CNOOC Limited (NYSE: CEO, SEHK: 883, "the
Company") announced today that Typhoon Chan Chu did not cause any casualties
or oil spillage due to the Company's continuous focus on health safety and
environment ("HSE").

Typhoon Chan Chu, the first one this year, made an unexpected 90 degree turn
after arriving in Eastern South China Sea. The center of Typhoon Chan Chu
struck directly at Liuhua oil field. The packing winds exceeded the maximum
resisting capacity on typhoon within a century. The Company had been
monitoring Typhoon Chan Chu and completed the evacuation before its arrival.
The Company mobilized 144 flights to evacuate over 3,840 offshore personnel
from 25 platforms and the floating processing storage and offloading units
("FPSO") of 17 oil fields in the Eastern South China Sea, including the staff
of our contractors. The Company shut down wells and production facilities
before the evacuation.

Thanks to the sufficient preparations, Typhoon Chan Chu did not cause any
casualties and oil spills.

After the landing of Typhoon Chan Chu, the Company thoroughly examined all the
oil fields in the area. None of the production facilities except those of
Liuhua oil field, were damaged and all have resumed production. Damages to
some of the production facilities in Liuhua oil field are discovered upon
examination. The Company has mobilized various service companies, including
subsea services and examination contractors to conduct the subsea examination
so as to determine damages. According to the examination, seven anchors and
three risers are split and broken.

The Company is arranging to tug the FPSO to safe areas. Meanwhile, We are also
organizing the designers, manufacturers and installation contractors etc. to
prepare a plan for resuming the production in the Liuhua oil field. The
production capacity of Liuhua oil field was approximately 22,000 barrels of
oil per day.

Mr. Zhou Shouwei, President of the Company commented: "During the strike of
Typhoon Chan Chu, we organized very large-scale evacuation and production
resumes in an efficient manner, leading to no casualties and no spillage. It
indicated the CNOOC Ltd's approach in taking HSE as a top priority. We are
still evaluating the situation and also working closely with the designers,
manufacturers, installation contractors as well as other related parties to
resume the production of Liuhua oil field as soon as possible."
