More than 1 million damage claims have been filed with a court-supervised settlement program. BP expects to complete payments into a planned $20 billion trust by the end of the year. BP said this spring that it had marked for sale its interests in Gulf fields known as Marlin, Horn Mountain, Holstein, Ram Powell and Diana Hoover. Bloomberg said the fields hold proven reserves of 120 million barrels of oil and produced 58,000 barrels per day in the first quarter. It said potential bidders could include Chevron Corp. and Exxon Mobil Corp. CEO Robert Dudley said last month that the company's Gulf strategy would focus on four major fields: Thunder Horse, Na Kika, Atlantis and Mad Dog. In July, BP reported a second-quarter loss of $1.4 billion on lower oil prices, falling production and write-downs of assets including shale-gas holdings in the U.S.
