CNOOC Limited (the "Company", NYSE: CEO, SEHK: 00883, TSX: CNU) today
announced its annual results for the year ended December 31, 2013.

In 2013, the Company continued to increase its investment in exploration.
Benefitting from the Company's cognitive innovation and technological
advancement, 18 new discoveries were made and 20 oil and gas structures were
successfully appraised by the Company. As at the end of 2013, the Company
owned net proved reserves of approximately 4.43 billion barrels of oil
equivalent ("BOE"). The reserve replacement ratio of the year amounted to

In 2013, the Company exceeded its production target set at the beginning of
the year. The net oil and gas production reached 411.7 million BOE,
representing a 20.2% increase year-over-year ("yoy"), with 60.8 million BOE
contributed by Nexen. During the year, a total of 7 new projects commenced
production in succession, and Liuhua 19-5 has also come online in early 2014.

In 2013, the Company's average realized oil price was US$104.60 per barrel,
representing a decrease of 5.3% yoy, and the Company's average realized gas
price was US$5.78 per thousand cubic feet, representing an increase of 0.2%
yoy. In addition, the Company's oil and gas sales revenue reached RMB226.45
billion, representing an increase of 16.3% yoy, and net profit amounted to
RMB56.46 billion.

During the period, the Company's all-in cost was US$45.02 per BOE,
representing an increase of 26.0% yoy, mainly attributable to the relatively
high cost of Nexen's assets and the new projects.

Including RMB15.67 billion of Nexen's spending, the Company's capital
expenditures reached RMB92.43 billion in 2013.

As for overseas development, with the successful completion of the acquisition
of Nexen in February 2013, the Company has embarked on a new phase of
international development. To date, the integration of the two entities has
progressed smoothly and the overall progress met the Company's targets. In
addition, the Company has successfully entered into the production sharing
contract for the Libra oil field located in the Santos Basin in Brazil. This
marks a significant milestone for the Company in the course of its strategic
entry into the ultra-deepwater field, which is in line with our philosophy of
expanding our global presence through partnership arrangements.

Mr. Li Fanrong, CEO of the Company, said, "In 2013, CNOOC Limited made steady
progress in all production and operational activities while stepping up the
pace of its international development. While working hard to achieve various

reforms and seeking long-term progress in order to create further value for
