So reports the L.A. Times, citing U.S. Coast Guard Adm. Thad Allen.
The “top kill” effort, launched Wednesday afternoon by industry and government engineers, 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 persists, 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.
In a month of nothing but bad news, this comes as a welcome change of pace.
