- hell in the gulf
The Deepwater Horizon oil spill is an oil spill in the Gulf of Mexico which flowed for three months in 2010. The impact of the spill still continues even from the well being capped. 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 Deepwater Horizon explosion. The explosion killed 11 men working on the platform and injured 17 others. On July 15, the leak was stopped by capping the gushing wellhead, after it had released about 4.9 million barrels (780×103 m3), or 205.8 million gallons of crude oil.
It was estimated that 53,000 barrels per day (8,400 m3/d) were escaping 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 (9,900 m3/d) and decreasing as the reservoir of hydrocarbons feeding the gusher was gradually depleted.
On September 19, the relief well process was successfully completed and the federal government declared the well "effectively dead".
The spill continues to cause extensive damage to marine and wildlife habitats as well as the Gulf's fishing and tourism industries.In late November, 4,200 square miles of the Gulf were re-closed to shrimping after tar balls were found in shrimpers' nets.The total amount of Louisiana shoreline impacted by oil grew from 287 in July to 320 miles in late November.
