FORWARD-LOOKING STATEMENTS
This prospectus supplement and the documents incorporated by reference include "forward-looking statements" within the meaning of the
United States Private Securities Litigation Reform Act of 1995, including statements regarding expected future events, business prospects or
financial results. The words "expect," "anticipate," "continue," "estimate," "objective," "ongoing," "may," "will," "project," "should," "believe,"
"plans," "intends" and similar expressions are intended to identify such forward-looking statements.
These forward-looking statements address, among others, such issues as:


· the amount and nature of future exploration, development and other capital expenditures;


· wells to be drilled or reworked;


· development projects;


· exploration prospects;


· estimates of proved oil and gas reserves;


· development and drilling potential;


· expansion and other development trends of the oil and gas industry;


· business strategy;


· production of oil and gas;


· development of undeveloped reserves;


· expansion and growth of our business and operations;


· oil and gas prices and demand;


· future earnings and cash flow; and


· our estimated financial information.
These statements are based on assumptions and analysis made by us in light of our experience and our perception of historical trends, current
conditions and expected future developments, as well as other factors we believe are appropriate under the circumstances. However, whether actual
results and developments will meet our expectations and predictions depend on a number of risks and uncertainties which could cause our actual
results, performance and financial condition to differ materially from our expectations, including those associated with fluctuations in crude oil and
natural gas prices, our exploration or development activities, our capital expenditure requirements, our business strategy, whether the transactions
entered into by us can complete on schedule pursuant to their terms and timetable or at all, the highly competitive nature of the oil and natural gas
industry, our foreign operations, environmental liabilities and compliance requirements, and economic and political conditions in the PRC and
overseas. For a description of these and other risks and uncertainties, see "Risk Factors" and other cautionary statements appearing in this
prospectus supplement and the documents incorporated by reference.
Consequently, all of the forward-looking statements made in this prospectus supplement and the documents incorporated by reference are
qualified by these cautionary statements. We cannot assure you that the results or developments anticipated by us will be realized or, even if
substantially realized, that they will have the expected effect on us, our business or our operations.

accompanying prospectus. It may not contain all of the information that you should consider before investing in the Notes. You should
carefully read this entire prospectus supplement, as well as the accompanying prospectus and the documents incorporated by reference herein
that are described under "Where You Can Find More Information About Us."
Our Business
CNOOC Limited
We are an upstream company specializing in the exploration, development and production of oil and natural gas. We are the dominant
oil and natural gas producer in offshore China and, in terms of reserves and production, we are also one of the largest independent oil and
natural gas exploration and production companies in the world.
As of the end of 2014, we had net proved reserves of approximately 4.48 billion BOE including approximately 2.46 billion barrels of
crude oil and 7,268.1 bcf of natural gas. In 2014, we had an average daily production of approximately 955,647 barrels of crude oil and
approximately 1,330.1 mmcf of natural gas, representing a total net oil and gas production of 1.18 million BOE per day, including
approximately 47,640 BOE per day under our equity method investees (except as otherwise stated, all amounts of reserve and production in
this prospectus supplement include our interests in equity method investees).
Our total revenues were RMB247.6 billion, RMB285.9 billion and RMB274.6 billion in 2012, 2013 and 2014, respectively. Our profit
for the year was RMB63.7 billion, RMB56.5 billion and RMB60.2 billion in 2012, 2013 and 2014, respectively.
We were incorporated with limited liability on August 20, 1999 in Hong Kong under the Hong Kong Companies Ordinance. The PRC
government established CNOOC, our controlling shareholder, as a state-owned offshore petroleum company in 1982 under the Regulation of
the PRC on the Exploitation of Offshore Petroleum Resources in Cooperation with Foreign Enterprises. CNOOC assumed certain
responsibility for the administration and development of PRC offshore petroleum operations with foreign oil and gas companies. Prior to
CNOOC's reorganization in 1999, CNOOC and its various affiliates performed both commercial and administrative functions relating to oil
and natural gas exploration and development in offshore China. In 1999, CNOOC transferred all of its then current operational and
commercial interests in its offshore petroleum business, including the related assets and liabilities, to us. As a result, we and our subsidiaries
are the only vehicles through which CNOOC engages in oil and gas exploration, development, production and sales activities both in and
outside the PRC.
Our registered office is located at 65th Floor, Bank of China Tower, One Garden Road, Central, Hong Kong, and our telephone number
is +852 2213-2500. We maintain a website at www.cnoocltd.com where general information about us is available. The contents of the website
are not part of this prospectus supplement or the accompanying prospectus.

CERTAIN FINANCIAL DATA
Recent Developments
We achieved a total net production of 118.3 million barrels of oil equivalent ("BOE") for the first quarter of 2015, representing an increase of
9.4% year-over-year, mainly attributable to the production contribution from new projects that commenced production since 2014 offshore China.
For the first quarter of 2015, we made three new discoveries and nine successful appraisal wells in offshore China.
Our unaudited oil and gas sales revenue reached approximately RMB35.54 billion for the first quarter of 2015, representing an decrease of
39.9% year-over-year, mainly due to the sharp decrease of international oil price. During the period, our average realized oil price decreased
49.0% year-over-year to US$53.40 per barrel, which is in line with the trend of international oil price. Our average realized gas price was US$6.68
per thousand cubic feet, representing an increase of 5.5% year-over-year, mainly due to the price hike with certain customers in China and higher
realized gas prices of new gas fields.
For the first quarter of 2015, our capital expenditure for exploration, development and production reached approximately RMB15.94 billion,
mainly because we proactively promote cost control and efficiency enhancement and cut our capital expenditures as a reaction to low oil price
environment.
