BP May Plug Its Gulf of Mexico Well in Four Days

- BP Plc may permanently plug in four days the Gulf of Mexico well that caused the largest offshore oil spill in U.S. history, National Incident Commander Thad Allen said.
A relief well is less than 25 feet (8 meters) from intercepting the damaged Macondo well and is expected to reach the outer cement shell within 24 hours, perhaps earlier, Allen said at a press conference today in Kenner, Louisiana. The relief well will be used to inject mud and cement into any remaining gaps, permanently killing Macondo. Injecting and testing the cement plug may take as long as four days, he said.
“They are almost touching the well,” Allen said. Operators aboard Transocean Ltd.’s Development Driller III rig are testing a new tool intended to measure the distance to the well while drilling. BP said yesterday the drilling bit had been temporarily withdrawn to check the distance using sensors.
The well began leaking oil after an April 20 explosion and fire that killed 11 workers aboard Transocean’s Deepwater Horizon drilling rig. The well gushed an estimated 4.9 million barrels of oil before BP capped it on July 15.
BP, based in London, plugged the well’s steel casing with cement in August, and Allen said he wants to assure the space between that casing and the wall that surrounds the hole also is blocked with cement.
Allen also said he’s ordered a “task force” of government, private and academic research vessels to survey a layer of oil more than 3 centimeters (1 inch) thick found Sept. 5 about 16 nautical miles (30 kilometers) from the well by researchers including Samantha Joye, a University of Georgia professor.
