VOLUNTARY ANNOUNCEMENT

 

This announcement is made by CNOOC Limited (the “Company”) on a voluntary basis.

 

Nexen Energy ULC, an indirectly wholly-owned subsidiary of the Company (“Nexen”), initiated an internal audit of its corporate pipeline integrity management system in early July 2015 as part of its Process Safety Management program in relation to its oilsands operation located at Long Lake, Alberta, Canada. The audit identified a number of non-compliances primarily related to documentation of maintenance activities. On 25 August 2015 (Canada time), Nexen voluntarily self-disclosed the findings to the Alberta Energy Regulator (“AER”), along with a schedule for an action plan. Subsequent to the self-disclosure by Nexen, AER issued a suspension order on 28 August 2015 (Canada time) immediately suspending the operations authorized under 15 pipeline licences granted to Nexen under the Pipeline Act RSA 2000 and such licences shall remain suspended until the suspension order is rescinded in writing by the AER.

 

The suspended pipeline licences under the suspension order relate to pipelines from the oilsands operation of Nexen in Long Lake, Alberta, Canada. The Company is of the view that, based on the information currently available, the suspension order is not expected to have any material impact on the operations and financial condition of the Group as a whole.

 

The level of non-compliance or the enforcement action (if any) that Nexen may face will be determined by the AER as part of the investigation into the matter. Nexen will continue to work with the AER to rescind the suspension order to satisfy the AER that the pipelines can be operated safely.

 

In the meantime, holders of shares and securities and potential investors of the Company should exercise caution when dealing in the securities of the Company.

 

If there is any significant development in relation to the matter, the Company will issue further announcements as and when required under the Listing Rules.
