ANNOUNCEMENT

The Board hereby announces certain selected unaudited key operational statistics of the Group for the first quarter of 2013 (ended 31 March 2013). The comparative statistics for the first quarter of 2012 (ended 31 March 2012) are also disclosed in this announcement.

The board of directors of CNOOC Limited (the “Company”) (the “Board”) hereby announces certain selected unaudited key operational statistics of the Company and its subsidiaries (together the “Group”) for the first quarter of 2013 (ended 31 March 2013). The comparative statistics for the first quarter of 2012 (ended 31 March 2012) are also disclosed in this announcement.

The Company achieved a total net production of 93.6 million barrels of oil equivalent (“BOE”) for the first quarter of 2013, representing an increase of 17.3% year over year (“YoY”), mainly attributable to: firstly, the production contribution from the acquisition of Nexen Inc. (“Nexen”); secondly, in offshore China, production contribution from new projects including Panyu 4-2/5-1 adjustment and Liuhua 4-1, and the resumption of production of Penglai 19-3 field ; thirdly, in overseas, production of Eagle Ford project in the U.S. and Missan oilfields in Iraq continue to increase.

For the first quarter of 2013, the Company made four new discoveries and six successful appraisal wells in offshore China. The Penglai 15-2 structure was proved to be a mid to large size crude oil discovery.

In February 2013, the Company successfully completed the acquisition of Nexen.

The unaudited oil and gas sales revenue of the Company reached approximately RMB55.31 billion for the first quarter of 2013, representing an increase of 13.3% YoY, mainly due to the increase of oil and gas production. During the period, the Company’s average realized oil price decreased 8.7% YoY to US$110.29 per barrel mainly due to the weak performance of the Far East benchmark oil prices. The Company’s average realized gas price was US$5.79 per thousand cubic feet, representing a decrease of 1.5% YoY, mainly due to the lower realized gas price of Nexen.

For the first quarter of 2013, the Company's capital expenditure for exploration, development and production reached approximately RMB14.80 billion, representing an increase of 53.5% YoY.
