Chevron Reopens Bidding on Texas Refinery: The San Francisco-based oil company has reopened talks to sell its Port Arthur refinery to St. Louis-based Clark Refining & Marketing Co., according to officials with both companies. A source close to the negotiations said Chevron Corp. has also fielded inquiries from other potential bidders for the 185,000 barrel-a-day refinery. A Chevron spokeswoman declined to comment on the progress of negotiations. A Clark spokesman said negotiations have been ongoing but declined to discuss details of the talks. In January, Chevron terminated an agreement to sell the refinery for an estimated $199 million after Clark, a unit of Toronto-based Horsham Corp., was unable to obtain financing for the deal.
