Engineers have stopped the flow of oil and gas into the Gulf of Mexico from a gushing BP well, the federal government’s top oil-spill commander, U.S. Coast Guard Adm. Thad Allen, said Thursday morning. The “top kill” effort, launched Wednesday afternoon by industry and government engineers, had pumped enough drilling fluid to block oil and gas spewing from the well, Allen said. As of early this morning, neither government nor BP officials had declared the effort a success yet, pending the completion of the cementing and sealing of the well.
Allen also said one ship that was pumping fluid into the well had run out of the fluid, or “mud,” and that a second ship was on the way. He said he was encouraged by the progress.
