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 oil spill in the Gulf of Mexico which flowed unabated for three months in 2010, and may be continuing to seep. It is the largest accidental marine oil spill in the history of the petroleum industry. The spill stemmed from a sea-floor oil gusher that resulted from the April 20,2010, explosion of Deepwater Horizon, which drilled on the BP-operated Macondo Prospect. The explosion killed 11 men working on the platform and injured 17 others. On July 15,2010, the gushing wellhead was capped, after it had released about 4.9 million barrels (780,000 m) of crude oil. An estimated 53,000 barrels per day escaped from the well just before it was capped. It is believed that the daily flow rate diminished over time, starting at about 62,000 barrels per day and decreasing as the reservoir of hydrocarbons feeding the gusher was gradually depleted. On September 19,2010, the relief well process was successfully completed, and the federal government declared the well effectively dead. In August 2011, oil and oil sheen
