Reporting from Houma, La. 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, U.S. Coast Guard Adm. Thad Allen, said Thursday morning. 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. j.mp ROCKMAN on May 27, 2010 - 9:03am Patience IP et al. If they have killed the well there is still a long and uncertain way to go. They'll have to pull the drill pipe out of the hole before they can begin thinking about P&A. And it may locked up in the BOP. And if the cab fish the DP out it will have to be done carefully: even if they killed the well they can "swab" the well in (make it start flowing again) by the action of pulling the DP out.

Deepwater Oil Spill - A Comparison of Flows, A Little Optimism, and a Live Comment Thread Posted by Heading Out on May 27, 2010 - 8:30am Below the fold are two pictures to show why I believe that the injection pressure of mud into the well has dropped, indicating that BP have filled the well, and are now holding pressure to see if there are any problems. I would assume, if none develop, that they will inject cement to seal the top of the well, sometime today.
