LONDON (Dow Jones)--The chief executives of the world's biggest international oil companies will testify Tuesday that the BP PLC (BP.LN) oil spill in the Gulf of Mexico "was preventable," publicly distancing themselves for the first time from the U.K. company, the Financial Times reports Monday. Executives from Exxon Mobil Corp. (XOM), Royal Dutch Shell PLC (RDSA), Chevron Corp. (CVX) and ConocoPhillips (COP) will say that by following current "best practices" companies can avoid such accidents, according to interviews with those who have seen the planned remarks,the FT says. The oil majors want to use this opportunity--before a subcommittee of the House energy and commerce committee--to make the case for continued new drilling in the deepwater gulf, the FT says.
