HOUSTON — Shell Oil Co. and Saudi Refining Inc. said they are open to talks with Texaco Inc. about buying its stakes in Equilon Enterprises LLC and Motiva Enterprises LLC following the Federal Trade Commission’s approval of Chevron Corp.’s $46.3 billion acquisition of Texaco Friday afternoon.

To pass FTC muster and form with Chevron the world’s fifth-largest largest oil company, Texaco agreed to sell six U.S. refineries and sever ties with 14,000 gasoline stations. The assets were placed in joint ventures in 1998 with Shell, and Saudi Refining. The FTC’s order provides a “practical framework” for the purchase of Texaco’s 33 percent stake in Motiva, Shell and Saudi Refining said in a prepared statement. Shell also wants to buy Texaco’s 44 percent interest in Equilon.
