when did the deepwater horizon oil spill happen
Deepwater Horizon oil spill The Deepwater Horizon oil spill (also referred to as the BP oil spill, the BP oil disaster, the Gulf of Mexico oil spill, and the Macondo blowout) is an industrial disaster that began on 20 April 2010, in the Gulf of Mexico on the BP-operated Ma,[6][7][8][9] it is considered the largest marine oil spill in the history of the petroleum industry and estimated to be 8% to 31% larger in volume than the previous largest, the Ixtoc I oil spill. The U.S. government estimated the total discharge at 4.9 million barrels (210 million US gal; 780,000 m3).[3] After several failed efforts to contain the flow, the well was declared sealed on 19 September 2010.[10] Reports in early 2012 indicated that the well site was still leaking.[11][12]
Deepwater Horizon oil spill Numerous investigations explored the causes of the explosion and record-setting spill. The U.S. government September 2011 report pointed to defective cement on the well, faulting mostly BP, but also rig operator Transocean and contractor Halliburton.[21][22] Earlier in 2011, a White House commission likewise blamed BP and its partners for a series of cost-cutting decisions and an inadequate safety system, but also concluded that the spill resulted from "systemic" root causes and "absent significant reform in both industry practices and government policies, might well recur".[23]
Efforts to stem the Deepwater Horizon oil spill On September 10, Allen said the bottom kill could start sooner than expected because a "locking sleeve" could be used on top of the well to prevent excessive pressure from causing problems. BP said the relief well was about 50 feet (15Â m) from the intersection, and finishing the boring would take four more days.[51] On September 16, the relief well reached its destination and pumping of cement to seal the well began.[52] Officials said on September 18 that the cement pumped in from the base of the well had completed the sealing of the well.[53] On September 19, after pressure testing, Allen declared the well "officially dead".[54]
