CNOOC Limited Enters Into Definitive Agreement to Acquire Nexen Inc.

CNOOC Limited and Nexen Inc. announced today that they have entered into a definitive agreement under which CNOOC Limited will acquire all of the outstanding common shares of Nexen for US$27.50 per share in cash.

The purchase price represents a premium of 61% to the closing price of Nexen's common shares on the NYSE on July 20, 2012, and a premium of 66% to Nexen's 20 trading-day volume-weighted average share price. Total cash consideration of approximately US$15.1 billion will be paid for Nexen's common and preferred shares, and Nexen's current debt of approximately US$4.3 billion will remain outstanding. The transaction, which will be completed by way of a plan of arrangement, is expected to close in the fourth quarter of 2012.

The acquisition of Nexen expands CNOOC Limited's overseas businesses and resource base in order to deliver long-term, sustainable growth. Nexen will complement CNOOC Limited's large offshore production footprint in China and extends CNOOC Limited's global presence with a high-quality asset base in many of the world's most significant producing regions - including Western Canada, the U.K. North Sea, the Gulf of Mexico and offshore Nigeria - focused on conventional oil and gas, oil sands and shale gas. In addition, Nexen management's current mandate will be expanded to include all of CNOOC Limited's North American and Caribbean assets.

Nexen had average production of 207 mboe/d (after royalties) in Q2 2012. In accordance with SEC rules, Nexen had 900 mmboe of proved reserves and 1,122 mmboe of probable reserves as of December 31, 2011. In addition, as of December 31, 2011, Nexen had best estimate contingent resources of 5.6 billion boe in accordance with Canadian National Instrument 51-101, predominantly in the Canadian oil sands.

The transaction will be funded by CNOOC Limited's existing cash resources and external financing.

Mr. Wang Yilin, Chairman of CNOOC Limited said, "The acquisition reflects our strong belief in Nexen's rich and diverse portfolio of assets and world-class management and employees. This is an exciting opportunity for us to build on our existing joint venture relationship with Nexen in Canada, and to acquire a leading international platform in the process. We strongly believe that this acquisition will create long-term value for CNOOC Limited's shareholders."

Commenting on the acquisition, Mr. Barry Jackson, Chairman of the Board of Nexen, said, "This transaction delivers significant and immediate value to Nexen shareholders. The Nexen Board is unanimous in its view that the transaction is in the best interest of Nexen and recommends shareholders vote in favor of the transaction."

Benefits to Canada

CNOOC Limited has been a significant investor in Canada since 2005, with total capital invested of C$2.8 billion. These investments include a stake in MEG Energy Inc.

CNOOC Limited intends to retain Nexen's current management team and employees.

CNOOC Limited will implement and enhance Nexen's current planned capital expenditure program, thereby investing significant capital in Canada and in Nexen's other international assets. CNOOC Limited brings greater financial capacity to better realize the full potential of Nexen's significant resource base.

About Nexen　

Nexen is an independent, Canadian-based global energy company, listed on the Toronto and New York stock exchanges under the symbol NXY. Nexen is focused on three growth strategies: oil sands and shale gas in Western Canada and conventional exploration and development primarily in the North Sea, offshore West Africa and deepwater Gulf of Mexico. Nexen adds value for shareholders through successful full-cycle oil and gas exploration and development, and leadership in ethics, integrity, governance and environmental stewardship.

　Conventional Oil & Gas

We have onshore production in Canada, Yemen and Colombia,
with the largest component of our conventional business occurring offshore, in the UK North Sea, Gulf of Mexico and the Atlantic Ocean, near West Africa.
In 2012, approximately 70% of our production is expected to come from offshore facilities.

UK North Sea
Nexen is the second largest oil producer in the UK North Sea, thanks to the resource-rich Buzzard facility, which in 2011 generated about 62,000 boe/d net to Nexen. We’ve doubled our proved reserves in the North Sea since 2004 and continue to actively explore in the region. The Golden Eagle development is our next major UK project, and one of the biggest discoveries in the region in the past decade. First oil production is expected in late 2014 and the development is expected to have initial gross production of 26,000 boe/d net to Nexen. We’re also pursuing a number of tieback opportunities to existing facilities to deliver near-term growth.

West Africa
Offshore West Africa is another core area that’s expected to contribute high-margin production. At full capacity, the Usan Floating Production, Storage and Offloading (FPSO) unit has the capacity to handle 180,000 barrels of oil per day (bbls/d). Of that capacity, 36,000 bbls/d is net to Nexen. We also have a strong inventory of follow-up prospects and expect offshore West Africa to be part of our growth plans for many years.

Gulf of Mexico
Nexen is one of the largest leaseholders in the Gulf of Mexico, with more than 100 prospects. Our joint venture discoveries at Appomattox are our best yet. Located about 72 miles off the Louisiana coast, Appomattox is estimated to contain (net to Nexen) 65 mmboe of probable reserves of light oil and approximately 50 mmboe (ranging from 25 to 90 mmboe) of contingent resources of light oil. 

　

　Oil Sands

We’re a major player in Canada’s oil sands with investments in oil sands mining, in-situ bitumen production and upgrading. We operate the Long Lake oil sands facility, that uses innovative technology to develop this vast resource.

Canada is home to the world’s third largest hydrocarbon basin – the oil sands. This abundant, secure and long-term resource offers significant energy potential for Canadians and the world market. As much as 1.7 trillion barrels of oil is estimated to be contained in the oil sands, of which approximately 173 billion barrels can be recovered using today’s technology.

　Shale Gas

Like all natural gas, shale gas is a clean-burning and abundant resource. We produce shale gas in northeastern British Columbia, Canada and we’re exploring development opportunities in Poland and Colombia.
　

We recognized the potential of shale gas early and in 2006 began acquiring large blocks of high-quality acreage in the Horn River Basin located in northeast British Columbia, Canada — one of the most prospective gas fields in North America. In 2010, we purchased more land in the nearby Cordova and Liard basins, bringing our total land position to approximately 300,000 acres.

Third-party evaluators have estimated that our land in the Horn River and Cordova basins hold between four trillion and 15 trillion cubic feet of recoverable contingent resources, while the Liard lands contain an estimated five trillion to 23 trillion cubic feet of prospective resources.¹

Our focus on operational excellence has built our reputation as a leader in shale gas development. We’re driving down operating costs and increasing efficiency – a critical element of delivering gas to markets given current commodity pricing. Importantly, we’ve made these strides while also maintaining our high standard for safety and the environment.
