CNOOC Limited Announces Key Operational Statistics

During the quarter, the Company achieved a total net production of 93.6 million barrels of oil equivalent (BOE), representing 17.3% increase year over year (YoY), primarily attributable to the production contribution from the acquisition of Nexen Inc (“Nexen”) , the new oil and gas projects on stream, the resumption of Penglai 19-3 oil field and the overseas projects.

For the first quarter, the Company made four new discoveries and six successful appraisal wells in offshore China. The appraisal confirmed that Penglai 15-2 was a mid to large sized crude oil discovery. In the perspective of overseas development, the Company successfully completed the acquisition of Nexen.

The Company’s average realized gas price went down 1.5% YoY to US$5.79 per thousand cubic feet, primarily due to the relatively lower realized gas price of Nexen.
