ANNOUNCEMENT

The board of directors of CNOOC Limited (the “Company") (the “Board”) announces that ConocoPhillips China Inc (“COPC”), the Operator of Penglai (PL)19-3 field, has informed the Company today that The State Oceanic Administration of People’s Republic of China (“SOA”) has required COPC to suspend the production in relation to Platforms B and C of PL19-3 field until the risk of oil spill is eliminated.

PL19-3 field is an oil field under Production Sharing Contract (the “PSC”). As the Operator, COPC is responsible for the management of the daily operations. The Company holds 51% of participating interests under the PSC. Based on COPC’s previous report to the Company, the oil leakage which started in June 2011 had been contained.  However, according to the latest report of COPC, a thin sheen has been observed recently near Platform B of PL19-3 field and bubbles have occasionally been generated from the oil-based mud which remains on the sea floor near Platform C of PL19-3 field. COPC is continuing with the clean up work, including diving operations to remove any residual oil-based mud on the sea floor at Platform C of PL19-3 field. Meanwhile, COPC continues to closely monitor the original seep location of Platform B of PL19-3 field.

Prior to the suspension of production, the Company’s net production from Platforms B and C of PL19-3 field was approximately 22,000 barrels per day.  The Company will continue to closely monitor the situation and issue further announcement as and when required under the Rules Governing the Listing of Securities on The Stock Exchange of Hong Kong Limited (the “Listing Rules”).

As the non-operator, the Company will continue to urge and assist COPC to complete the clean-up work as quickly as possible, and to reduce the impact of the oil spill incidents on marine environment according to SOA’s requirement.

This announcement is made pursuant to Rule 13.09(1) of the Listing Rules.
