(Adds background, further comment) By James Herron Of DOW JONES NEWSWIRES 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. Talks between BP and Apache over Alaskan assets were dropped shortly before their $7 billion deal was announced because of the complexity of the field's ownership structure, according to people familiar with the matter. BP owns a 26% stake in Prudhoe Bay, with the rest owned by Exxon Mobil Corp. (XOM), ConocoPhillips (COP) and Chevron Corp. (CVX). Apache typically prefers to operate the assets it owns, and with Prudhoe Bay it wasn't certain that it would be in charge, the people familiar with the matter said. Removing the Alaskan assets helped simplify the deal and move it forward. An Apache acquisition of the Alaska assets hasn't been ruled, but there is a list of several other potential buyers, a person said. Analysts and investors said BP got a good price from the sale of oil and gas exploration and production assets in North America and Egypt to Apache. The speed of the sale should dispel any concerns about BP's liquidity in the face of tens of billions of dollars of costs related to the Gulf of Mexico oil spill, they said. -By James Herron, Dow Jones Newswires; +44 (0)20 7842 9317; james.herron@dowjones.com (Guy Chazan and Gina Chon contributed to this article.)
