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)^[6] is an oil spill in the Gulf of Mexico which flowed unabated for three months in 2010, and may be continuing to leak.^[7][8] Named the largest accidental marine oil spill in the history of the petroleum industry, its source was a sea-floor oil gusher resulting from the 20 April 2010 Deepwater Horizon explosion which claimed 11 lives.^{[9][10][11][12]} The Deepwater Horizon drilled on the BP-operated Macondo Prospect, block 252. The gushing wellhead was capped after 87 days, on 15 July 2010.^[11][13] The total discharge is estimated at 4.9 million barrels (210 million US gal; 780,000 m³).^[3] The well was declared sealed on 19 September 2010.^[14]
