LONDON (Dow Jones)--Some of BP PLC's (BP) oil production assets in Alaska remain up for sale, despite not being included in a $7 billion package of assets sold to U.S. energy company Apache Corp. (APA) Tuesday, said people familiar with the matter Wednesday. BP is also proceeding quickly with talks with a number of parties about other asset sales that are part of a push to raise $10 billion to help cover the cost of the Gulf of Mexico oil spill, one of the people said. BP said Tuesday it will sell its natural gas assets in Pakistan and Vietnam. And the company has already had contacts with potential buyers for these assets, that person said. BP has also reportedly had talks with China National Offshore Oil Company (CEO) over the sale of its 60% stake in Pan American Energy, which operates primarily in Argentina, and has considered selling assets in the U.K. North Sea. -By James Herron, Dow Jones Newswires; +44 (0)20 7842 9317; james.herron@dowjones.com (END) Dow Jones Newswires July 21, 2010 10:39 ET (14:39 GMT)
