CNOOC Limited (the "Company", NYSE: CEO, SEHK: 00883, TSX: CNU) today announced its key operational statistics for the first quarter of 2015.

Total net production in the first quarter of 2015 increased 9.4% year over year ("YoY") to 118.3 million barrels of oil equivalent ("BOE"), primarily due to the production contribution from new projects that came on stream in offshore China since 2014.

In the first quarter, the Company made 3 new discoveries. In offshore China and overseas, the Company made 9 and 3 successful appraisal wells, respectively. In offshore China, the new discovery Penglai 20-2 is expected to drive the joint development with the adjacent Penglai 20-3 oil field. After successful appraisals, the Bozhong 34-9 oil and gas structure is expected to be developed into a mid-sized oil and gas field.

Jinzhou 9-3 comprehensive adjustment project and Kenli 10-1 oil field commenced production as scheduled in 2015, while other projects progressed smoothly.

During the period, the unaudited oil and gas sales revenue of the Company were approximately RMB35.54 billion, a decrease of 39.9% YoY, due to the sharp decline in international oil prices. The Company's average realized oil price decreased by 49.0% YoY to US$53.40 per barrel while the average realized gas price increased by 5.5% YoY to US$6.68 per thousand cubic feet.

Facing the challenges created by low oil prices, the Company continued to lower costs and enhance efficiency, and adjusted its operating strategy by decreasing capital expenditures. In the first quarter, the Company's capital expenditures decreased by 15.7% YoY to approximately RMB15.94 billion.

Mr. Li Fanrong, CEO of the Company commented, "Under the harsh circumstances, the Company's overall production and operations remained stable in the first quarter. Our cost control and enhanced efficiency measures were executed effectively and achieved good results. We will continue to strengthen our internal operations management, exercise strict cost control and enhance efficiency to proactively respond to the impact of low oil prices and to effectively promote various production and operational plans."
