Washington, Dec 10: An expert committee of the National Academy of Engineering and National Research Council has issued its final report over the 2010 Deepwater Horizon explosion and oil spill in the Gulf of Mexico.
The report, Macondo Well-Deepwater Horizon Blowout: Lessons For Improving Offshore Drilling Safety, comes after the committee conducted a technical analysis of the causes of the explosion and the oil spill.
It analyzes the performance of the technologies and practices used, including the blowout preventer and related technology features, and recommends a number of actions that industry and regulators should take to decrease the risk of danger in future drilling operations.
The Deepwater Horizon oil spill (also referred to as the BP oil spill, the Gulf of Mexico oil spill, the BP oil disaster, or the Macondo blowout) is an oil spill in the Gulf of Mexico which flowed unabated for three months in 2010.
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 leak was stopped by capping the gushing wellhead, after it had released about 4.9 million barrels 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 United States declared the well "effectively dead".
The spill caused extensive damage to marine and wildlife habitats and to the Gulf's fishing and tourism industries. (ANI)
