Sep. 2009 - Nexen continues its significant growth in the UK North Sea, announcing the discovery of substantial additional resources and the start up of new production. Based on Nexen's assessment of the data acquired to date, including three exploration wells, nine appraisal wells, three drill-stem tests, one injectivity test and extensive core data, the company estimates that the Golden Eagle area contains between 150 and 275 million boe of gross recoverable contingent resources and is becoming a major development project. The Golden Eagle area includes Nexen's 34% operated interest in both the Golden Eagle and Hobby discoveries and its 46% operated interest in the Pink discovery.

Mar. 2009 - The Hobby discovery well flowed at an average restricted rate of 5,500 bopd through a 56/64-inch choke. Early analysis indicates high-quality crude oil in good-quality reservoir sands. Multiple sidetracks are planned. Hobby was discovered in February 2009 in the UK North Sea on Block 20/1N, west of Golden Eagle. Nexen serves as the operator.

Feb. 2009 - Nexen is currently assessing future appraisal and development alternatives for the growing Golden Eagle area. The company plans to drill multiple sidetracks to determine the extent for the field. Nexen has identified additional prospects in the area and have plans for further exploratory and appraisal drilling this year.

Feb. 2009 - Nexen has announced an oil discovery at the Hobby exploration well, where Nexen is the operator with a 34% interest. Drilled by the Transocean Prospect semisub, the discovery is located in the UK Central North Sea Block 20/1N approximately 1.5 km west of the recent Golden Eagle discovery.

Feb. 2009 - In the first quarter of 2007, the Golden Eagle discovery well was drilled to a depth of approximately 7,500 feet and encountered 123 feet of net pay. A successful sidetrack well was drilled to appraise the accumulation, and Nexen is currently evaluating development options. The current estimate of gross resource for the field is between 20 and 50 mmboe.

Feb. 2009 - In the fourth quarter of 2008, Nexen drilled a discovery at Pink that encountered 57 feet of net oil pay. This discovery was followed up with a sidetrack delineation well that encountered 134 feet of net oil pay. These results are encouraging and consistent with pre-drill estimates. Pink is a candidate for co-development with Golden Eagle where Nexen is currently reviewing development options.
