CHAIRMAN’S STATEMENT

Dear Shareholders,

In the first half of the year, the global economic situation was critical, and China’s economic growth encountered challenges. Under this environment, CNOOC Limited followed the blueprint of “A new leap forward” as the guiding principle, actively sought opportunities amidst crisis, and realised steady growth in its different areas of business. We overcame the difficulties including a small decline in production and escalating costs and maintained strong profitability. Our net profit reached RMB 31.87 billion and once again delivered satisfactory results for our shareholders.

To realize the “new leap forward” plan, we continued to focus on our exploration program. During the first half of the year, our efforts achieved encouraging returns in our core area – offshore China. With the successful discoveries and appraisals of the mid-to-large scale oil and gas structures including Penglai 9-1 and Kenli 2-1, we strengthened our resource base for long term growth in offshore China. Our independent exploration activities in deepwater areas in the South China Sea also started to unfold the resource potential in the region. These exploration progresses made in offshore China reinforced our confidence in the sustainable development of the Company.

The Company’s development and production operations in both offshore China and overseas saw many highlights. The performance of the producing oil and gas fields in offshore China was satisfactory through the adoption of production enhancement measures such as infill drilling and new technologies such as thermal recovery of heavy oil. The production volume for overseas projects has been ramping up at a steady pace. These have effectively compensated for the production losses from the shutdown of the Penglai 19-3 oilfield, enabling the Company to maintain a relatively high level of net oil and gas production despite a series of difficulties. The Company will continue to work hard to realize its annual production target.

The Company also achieved new breakthrough in its overseas development. In July, we signed an agreement for the acquisition of Nexen Inc. in Canada. Upon the closing of the transaction, the Company will become a truly global oil and gas exploration and production company with a balanced resources portfolio and important presences in the world’s major oil and gas production areas. At the same time, we will be able to acquire the world class management team and employees from Nexen and establish a leading international development platform. We are confident that the transaction will be able to create long term value for our shareholders.

In consideration of the capital requirements of the Nexen transaction and to maintain financial flexibility and support the Company’s long-term growth, the board of directors of the Company has decided to pay an interim dividend of HK$0.15 (tax inclusive) per share for 2012.

In view of rapid developments in the different areas of the Company’s business and faced by the uncertain and complex external environment, we will put more emphasis on building our own capabilities. Upon the foundation of a relatively effective management system and an internal risk control mechanism, we will continue our effort to ensure safe and environmental-friendly production, to strengthen our risk control and innovative ability in scientific technology and management as well as to build up a pool of talents and employees. We shall enhance our core management, strengthen our development foundation, and continuously raise the Company’s core competitiveness and capability of sustainable development. We will strive to build up a strong foundation for the Company’s “A new leap forward” blueprint and to continue to create value and returns for our shareholders.

CEO’S STATEMENT

Dear Shareholders,

Following the blueprint of “A new leap forward”, CNOOC Limited carried out its various businesses in a steady and orderly manner and achieved stable growth for its results in the first half of 2012.

Review of the first half year

During the first half of the year, downward pressure for the world’s economic growth was mounting as Europe’s debt crisis continued to deepen; international oil prices decreased significantly from a high level. Under these circumstances, our entire staff members worked hard to promote the continued development of the Company’s exploration, development and production and other businesses. We continue to maintain good records in perspective of health, safety and environmental protection.

First of all, the Company’s exploration work achieved encouraging results. During the first half of the year, 10 discoveries were made and 18 appraisal wells were successful. Meanwhile, significant progresses were made in different fronts. In the Bohai area, we made four major achievements: firstly, a series of appraisal wells were successful, proving Penglai 9-1 to be the biggest oil and gas structure discovered in Bohai in recent years; secondly, we made a mid-to-large discovery Kenli 2-1, which contains medium to light crude oil; thirdly, the successful appraisal of Qinhuangdao 29-2 East structure was made, extending the original Qinhuangdao 29-2 structure and enlarging its reserve scale; lastly, two new discoveries, Luda 21-2 and Luda 6-2, made in the Liaodong Bay area were both mid-sized discoveries, opening up a new exploration field with ample potentials in this area. In Western South China Sea, breakthrough was once again achieved in the Yinggehai high-temperature high-pressure zone, resulting in the Dongfang 13-2 natural gas discovery.

In addition, independent deep water exploration progressed smoothly. As planned, we have proceeded with independent drilling in the deep water area in South China Sea, accumulating extensive operation technologies and management experiences. Natural gas discovery was made in the Liuhua 29-2 structure, demonstrating a brighter future for the area’s exploration.

For the first half of the year, the Company’s net oil and gas production reached 160.9 million BOE. Our net production decreased 4.6% year over year (YoY) mainly due to the Penglai 19-3 oilfield, the scheduled shutdown and maintenance, and the disposal of the ONWJ block in Indonesia. By bringing the new projects on stream as scheduled, ensuring the stable operation of the facilities and equipment, and optimizing the technologies for production enhancement, we are confident to accomplish our annual production target of 330-340 million BOE established early this year.

The Company’s average realized oil price reached US$116.91 per barrel, representing an increase of 8.1% YoY; the average realized natural gas price reached US$5.90 per thousand cubic feet, representing an increase of 20.0% YoY. The Company maintained its strong profitability in the industry, with oil and gas sales reached RMB95.66 billion and net profit amounted to RMB31.87 billion. It is worth mentioning that due to rising industry costs and changes in the Company’s assets structure, our all-in cost for the first half of the year was US$34.60 per barrel, representing an increase of 13.1% compared to the whole year of 2011. In order to maintain our competitive cost structure, cost control will continue to be a key aspect for the management of the Company in the future.

Opening up a new horizon for overseas development

Since the beginning of the year, the Company has achieved satisfactory development in its overseas business, with overseas oil and gas production increasing significantly. The acquisition of one-third working interest in each of Exploration Area of 1, 2 and 3A in Uganda was also completed on 21 February 2012.

It is more encouraging that an agreement was reached between the Company and Nexen Inc. in Canada in July for the acquisition of the entire common shares and preferred shares of Nexen Inc. for a consideration of US$15.1 billion. The acquisition was consistent with CNOOC Limited’s established value-driven merger and acquisition strategy. The acquisition will not only increase the net proved reserve of the Company by around 30% and its net production by around 20%, but also bring to the Company invaluable experience in the area of unconventional oil and gas resources such as oil sands and shale gas, as well as a high-quality management team and employees.

Through the transaction, we will be able to expand our overseas business and resource base, enhance our presence in Canada, Gulf of Mexico and Nigeria, and enter the resourceful UK North Sea. It will further diversify CNOOC Limited’s growth platform and benefit our long term sustainable growth.

In the meantime, we will continue to enhance the management on our overseas assets and control the risks including the changes of fiscal regimes.

Outlook for the second half of the year

For the second half of the year, the world economy will likely to continue to bear the downward pressure and international oil prices are expected to become increasingly volatile. In view of the critical external environment, we will continue to ensure good business performance in different aspects of the Company, strengthening our foundation and striving for stable development.

In practical terms, the Company will focus on the following areas:
Firstly, continue to strengthen the fundamental management and the system of health, safety and environmental protection to ensure safe and environmental-friendly production.
Secondly, commence new projects on schedule, implement production enhancement measures such as infill drilling, and ensure our annual production target be accomplished.
Thirdly, focus on the appraisal of new discoveries made in the first half of the year and continue to implement exploration program.
Fourthly, carry out the follow up work of the transaction with Nexen.
Lastly, strengthen core management and focus on cost control and efficiency improvement.

The Company has embarked on a new development platform, establishing a portfolio with combination of independent and PSC operations, shallow water and deep water, domestic and overseas, as well as conventional and unconventional oil and gas resources. In the future, we will continue to enhance our core competitiveness and strive to deliver greater value to our shareholders.

NOTES TO INTERIM CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
30 June 2012
(All amounts expressed in millions of Renminbi, except number of shares and unless otherwise stated)

1.  
BASIS OF PREPARATION AND ACCOUNTING POLICIES

Basis of preparation

The interim condensed consolidated financial statements for the six months ended 30 June 2012 have been prepared in accordance with International Accounting Standards 34 (“IAS 34”) and Hong Kong Accounting Standards 34 (“HKAS 34”) Interim Financial Reporting.

The interim condensed consolidated financial statements do not include all the information and disclosures required in the annual financial statements, and should be read in conjunction with the Group’s annual financial statements as at 31 December 2011.

Significant accounting policies

The accounting policies adopted in the preparation of the interim condensed consolidated financial statements are consistent with those followed in the preparation of the Group’s annual financial statements for the year ended 31 December 2011. The adoption of new standards and interpretations as of 1 January 2012 does not have any material impact on the accounting policy, interim financial position or performance of the Group.

Improvements to IFRSs/HKFRSs

The IASB/HKICPA has issued improvements to IFRSs/HKFRSs which set out amendments to a number of IFRSs/HKFRSs primarily with a view to remove inconsistencies and clarify wording. The adoption of those amendments upon their effective dates did not have any material impact on the accounting policies, interim financial position or performance of the Group.

2.  
ACQUISITIONS AND OTHER VENTURE

On 29 March 2011, CNOOC Uganda Ltd, a wholly-owned subsidiary of CNOOC International Limited, entered into a sales and purchase agreement with Tullow Uganda Limited and Tullow Uganda Operation Pty Ltd., wholly-owned subsidiaries of Tullow Oil Plc., to acquire a one-third working interest in Uganda Exploration Areas 1, 2 and 3A (the “Uganda Assets”) for an initial cash consideration of US$1.467 billion. The acquisition of the Uganda Assets was completed on 21 February 2012. Together with the related price adjustment, the cash consideration mentioned above has been recorded as acquisition costs of oil and gas properties.

3.  
OIL AND GAS SALES AND MARKETING REVENUES

Oil and gas sales represent the invoiced value of sales of oil and gas attributable to the interests of the Group, net of royalties and the government share oil that is lifted and sold on behalf of the government. Revenue from the sale of oil is recognised when the significant risks and rewards of ownership have been transferred, which is when title passes to the customer. Revenue from the production of oil and gas in which the Group has a joint interest with other producers is recognised based on the Group’s working interest and the terms of the relevant production sharing contracts.

SEGMENT INFORMATION

The Group is organised on a worldwide basis into three major operating segments. The Group is involved in the upstream operating activities of the petroleum industry that comprise independent operations, operations under joint arrangement and trading business. These segments are determined primarily because the Group’s chief operating decision maker makes key operating decisions and assesses performance of the segments separately. The Group evaluates the performance of each segment based on profit or loss from operations before income tax.

The Group mainly engages in the exploration, development, production and sales of crude oil, natural gas and other petroleum products in offshore China. Activities outside the PRC are mainly conducted in Indonesia, Australia, Nigeria, Argentina, the United States of America, Canada, Uganda and Singapore.

The following table presents revenue, profit and assets information for the Group’s operating segments.

The interim results for the six months ended 30 June 2012 are unaudited, but have been reviewed by Ernst & Young in accordance with Hong Kong Standard on Review Engagements 2410 "Review of Interim Financial Information Performed by the Independent Auditor of the Entity", issued by the Hong Kong Institute of Certified Public Accountants. The interim results have been reviewed by the Audit Committee.

PURCHASE, SALE OR REDEMPTION OF THE COMPANY’S LISTED SECURITIES
 
On 10 January 2012, the Company cancelled 12,875,000 of the 22,894,000 shares repurchased in 2011. During the six months ended 30 June 2012, there was no purchase, sale or redemption of the Company’s listed securities by the Company or any of its subsidiaries.

CODE ON CORPORATE GOVERNANCE PRACTICES
 
For the six months ended at 30 June 2012 (before and after the revision to the Code on Corporate Governance Practices as set out in Appendix 14 to the Listing Rules (now known as the “Corporate Governance Code and Corporate Governance Report”) came into effect on 1 April 2012), the Company has complied with relevant code provisions set out in Appendix 14 to the Listing Rules, except for the deviation from the code provision A.4.1 of the Corporate Governance Code and Corporate Governance Report as set out in the Appendix 14 to the Listing Rules. The following summarises the requirement under the above-mentioned code provision A.4.1 and the reason for such deviation.

Code Provision A.4.1
 
Under Code Provision A.4.1, non-executive directors should be appointed for a specific term and be subject to re-election.

None of the existing Independent Non-executive Directors of the Company is appointed for a specific term. This constitutes a deviation from Code Provision A.4.1. However, all the Directors are subject to the retirement provisions under article 97 of the Articles of Association of the Company (“Article 97”). According to Article 97, one-third of the Directors for the time being must retire from the office by rotation at each annual general meeting. The Company has observed the need for good corporate governance practices. All the incumbent Independent Non-executive Directors of the Company have retired from the office by rotation and have been re-elected in the past three years according to Article 97. Therefore, the Company considers that sufficient measures have been taken to ensure that the Company’s corporate governance practices are no less exacting than those in the Code.

MODEL CODE FOR SECURITIES TRANSACTIONS BY DIRECTORS OF LISTED ISSUERS
 
The Company has adopted a Code of Ethics for Directors and Senior Management (“Code of Ethics”) incorporating the Model Code for Securities Transactions by Directors of Listed Issuers (the “Model Code”) as set out in Appendix 10 to the Listing Rules. All Directors have confirmed that they complied, during the six months ended 30 June 2012, with the Company’s Code of Ethics and the required standards set out in the Model Code.

CHANGES IN SENIOR MANAGEMENT
 
During the six months ended 30 June 2012, there was the following change in senior management.

On 22 March 2012, Mr. Jiang Yongzhi resigned as Joint Company Secretary of the Company and Mr. Zhong Hua, the Chief Financial Officer, was appointed as Joint Company Secretary of the Company with effect from the same day.

CHANGES IN INFORMATION OF DIRECTORS

STATEMENT OF SIGNIFICANT DIFFERENCES IN CORPORATE GOVERNANCE PRACTICES FOR PURPOSES OF SECTION 303A.11 OF THE NEW YORK STOCK EXCHANGE LISTED COMPANY MANUAL
 
The Company is incorporated under the laws of Hong Kong. The principal trading market for the ordinary shares of the Company is the HKSE. In addition, because the Company’s ordinary shares are registered with the United Sates Securities and Exchange Commission and are listed on the New York Stock Exchange (the “NYSE”), the Company is subject to certain corporate governance requirements. However, many of the corporate governance rules in the NYSE Listed Company Manual (the “NYSE Standards”) do not apply to the Company as a “foreign private issuer” and the Company is permitted to follow its home country corporate governance practices in lieu of most corporate governance standards contained in the NYSE Standards. Section 303A.11 of the NYSE Listed Company Manual requires NYSE-listed foreign private issuers to describe the significant differences between their corporate governance practices and the corporate governance standards applicable to U.S. companies listed on the NYSE. The Company has posted a brief summary of such significant differences on its website, which may be accessed through the following web page:

FORWARD-LOOKING STATEMENTS
 
This interim report includes “forward-looking statements” within the meaning of the United States Private Securities Litigation Reform Act of 1995, including statements regarding expected future events, business prospectus or financial results.

These statements are based on assumptions and analyses made by the Company in light of its experience and its perception of historical trends, current conditions and expected future developments, as well as other factors the Company believes are appropriate under the circumstances. However, whether actual results and developments will meet the expectations and predictions of the Company depends on a number of risks and uncertainties which could cause the actual results, performance and financial condition to differ materially from the Company’s expectations, including those associated with fluctuations in crude oil and natural gas prices, the exploration or development activities, the capital expenditure requirements, the business strategy, whether the transactions entered into by the Group can complete on schedule pursuant to its timetable or at all, the highly competitive nature of the oil and natural gas industries, the foreign operations, environmental liabilities and compliance requirements, and economic and political conditions in the People’s Republic of China. For a description of these and other risks and uncertainties, please see the documents the Company files from time to time with the United States Securities and Exchange Commission, including the 2011 Annual Report on Form 20-F filed on 20 April 2012.

Exhibit 99.2
 
 
For Immediate Release
 
CNOOC Limited Maintains Strong Profitability and Achieves Good Exploration Performance in 1H2012

(Hong Kong, August 21, 2012) - CNOOC Limited (the “Company”, NYSE: CEO, SEHK: 00883) today announced its interim results ended June 30, 2012.

For the first half of the year, the Company’s average realized oil price reached US$116.91 per barrel, representing an increase of 8.1% year-over-year (YoY), and the average realized natural gas price reached US$5.90 per thousand cubic feet, representing an increase of 20.0% YoY.

During the period, the Company’s net oil and gas production reached 160.9 million BOE, a decrease of 4.6% YoY primarily caused by the shutdown of production of the Penglai 19-3 oilfield, the scheduled maintenance, and the disposal of the ONWJ block in Indonesia. By bringing the scheduled new projects on stream, ensuring the good performance of the facilities and equipments, and optimizing the technologies used for production enhancement, we are confident to accomplish our annual production target of 330-340 million BOE set by early this year.

Benefited from the rising average realized oil and gas prices, the oil and gas sales of the Company reached RMB95.66 billion and the net profit amounted to RMB31.87 billion, maintaining its strong profitability in the industry. Attributed to the rising industry costs and structural change of the Company’s asset portfolio, our all-in cost for the first half of the year was US$34.60 per barrel, representing an increase of 13.1% compared to that of year 2011.

The Company has achieved encouraging results in the exploration sector. In addition to 10 successful discoveries and 18 appraisal wells made in the first half, the Company also made significant progress in various fronts. A series of successful appraisal wells proved Penglai 9-1 would become the biggest oil and gas structure discovered in Bohai area in recent years. The successful appraisal of Qinhuangdao 29-2 East structure expanded the original Qinhuangdao 29-2 structure as well as its reserve scale. In this period, the company has also made mid-to-large sized discoveries including Kenli 2-1, Luda 21-2 and Luda 6-2. In addition, natural gas discovery was made in the
 
 
 
 

 
 
 
Liuhua 29-2 structure in deepwater of South China Sea, demonstrating a great exploration potential for the area.

In the meantime, The Company achieved new breakthrough in its overseas development. In February, the acquisition of one-third interest in each of Exploration areas of 1, 2 and 3A in Uganda was completed. In July, we signed an agreement for the acquisition of Nexen Inc. in Canada. This transaction will make the Company a truly global exploration and production company with a balanced resources portfolio and important presences in the world’s major oil and gas production areas.

Mr. Wang Yilin, Chairman of the Company commented, “In view of rapid developments in the different areas of the Company’s business and faced by uncertainties of the external environment, we will pay increasing attention to build our own capabilities. We shall enhance our core management, strengthen our development foundation, and continuously raise the Company’s core competitiveness and capability of sustainable development. We will strive to build up a strong foundation for the Company’s “A new leap forward” blueprint and to continue to create value and returns for our shareholders.”

Mr. Li Fanrong, CEO of the Company commented, “During the first half of the year, downward pressure for the world’s economic growth was mounting as Europe’s debt crisis continued to deepen and international oil prices decreased significantly from a high level. In view of the critical external environment, we will continue to ensure good performance in the different areas of business of the Company, strengthening our foundation and striving forward for future development.”
 
In consideration of the capital requirements of the Nexen transaction and to maintain financial flexibility and support the Company’s long-term growth, the Board of Directors has decided to pay an interim dividend of HK$0.15 (tax inclusive) per share for 2012.
