TOKYO (Dow Jones)--A U.S. Senate subcommittee will ask the president of an oil exploration company under the umbrella of Mitsui & Co. (8031.TO) to attend a hearing on the ongoing oil spill in the Gulf of Mexico, the Yomiuri Shimbun reports. The firm, MOEX Offshore 2007 LLC, has a stake in the oil fields in the area of the spill. The subcommittee of the Senate Homeland Security and Governmental Affairs Committee said Friday it would ask the company's president, Naoki Ishii, to soon attend a hearing on the massive oil spill. MOEX Offshore 2007 is a wholly owned subsidiary of Mitsui Oil Exploration Co., a subsidiary of Mitsui & Co. The panel will also ask Jim Hackett, chief executive officer of the U.S. oil company Anadarko Petroleum Corp. to attend the hearing, subcommittee sources said. BP PLC, a British-based multinational oil company, has a 65 percent stake in the oil fields stricken by the worst oil spill in U.S. history, while Mitsui Oil Exploration has a 10 percent interest and Anadarko holds the remaining 25 percent. BP has asked Mitsui Oil Exploration to pay 111 million dollars (about 9.8 billion yen) to cover part of expenses for preventing the oil slicks from spreading further and related purposes. -Tokyo Bureau, Dow Jones Newswires; +81-3-6269-2770 (END) Dow Jones Newswires July 11, 2010 18:44 ET (22:44 GMT)
