Engineers have succeeded in stopping the flow of oil and gas into the Gulf of Mexico from a gushing BP well, the federal government’s top oil spill commander, Adm. Thad Allen, said Thursday morning.
The so-called “top kill” effort, launched Wednesday afternoon by industry and government engineers in Houston, has pumped enough drilling fluid to block all oil and gas from the well, Allen said. The pressure from the well is very low, but persistent, he said.
Once engineers have reduced the well pressure to zero, they will begin to pump cement into the hole to entomb the well. To help that effort, he said, engineers are also pumping some debris into the blowout preventer at the top of the well.
