The Deepwater Horizon oil spill (also referred to as the BP oil spill, the Gulf of Mexico oil spill, the BP oil disaster or the Macondo blowout) is a massive ongoing oil spill in the Gulf of Mexico, now considered the largest offshore spill in U.S. history Some estimates placed it by late May or early June, 2010, as among the largest oil spills in the world with tens of millions of gallons spilled to date. The spill stems from a sea floor oil gusher that resulted from the April 20, 2010 Deepwater Horizon drilling rig explosion. The explosion killed 11 platform workers and injured 17 others.
The gusher, now estimated by the quasi-official Flow Rate Technical Group to be flowing at 35,000 to 60,000 barrels (1,500,000 to 2,500,000 US gallons; 5,600 to 9,500 cubic metres) of crude oil per day, originates from a deepwater wellhead 5,000 feet (1,500 m) below the ocean surface. The exact spill flow rate is uncertain due to the difficulty of installing measurement devices at that depth and is a matter of ongoing debate. The resulting oil slick covers a surface area of at least 2,500 square miles (6,500 km2), with the exact size and location of the slick fluctuating from day to day depending on weather conditions. Scientists have also reported immense underwater plumes of oil not visible at the surface.
New Chief Executive of BP Bob Dudley said:
"You will see the evidence of a pullback because we have booms across the shores all the way from Florida to Louisiana. Those only last for a certain number of tide cycles," Mr Dudley told reporters in Biloxi, Mississippi.
"And where there is no oil on the beaches you probably don't need people walking up and down in Hazmat suits. So you'll probably see that kind of a pullback. But commitment, absolutely no pullback."
