when was the deepwater horizon oil spill capped
Deepwater Horizon oil spill Concerns were raised about the appearance of underwater, horizontally extended plumes of dissolved oil. Researchers concluded that deep plumes of dissolved oil and gas would likely remain confined to the northern Gulf of Mexico and that the peak impact on dissolved oxygen would be delayed and long lasting.[61] Two weeks after the wellhead was capped on 15 July 2010, the surface oil appeared to have dissipated, while an unknown amount of subsurface oil remained.[62] Estimates of the residual ranged from a 2010 NOAA report that claimed about half of the oil remained below the surface to independent estimates of up to 75%.[63][64][65]
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]
Deepwater Horizon oil spill The Deepwater Horizon oil spill (also referred to as the BP oil spill/leak, 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 Macondo Prospect,[6][7][8][9] considered to be 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] [10]After several failed efforts to contain the flow, the well was declared sealed on 19 September 2010.[11] Reports in early 2012 indicated that the well site was still leaking.[12][13]
