The oil slick as seen from space by NASA's Terra satellite on 24 May 2010. The 2010 Deepwater Horizon oil spill in the Gulf of Mexico has been described as the worst environmental disaster in the United States, releasing about 4.9 million barrels (210 million US gal; 780,000 m 3) of crude oil making it the largest marine oil spill in history.
The same blowout that caused the explosion also caused an oil well fire and a massive offshore oil spill in the Gulf of Mexico, considered the largest accidental marine oil spill in the world, and the largest environmental disaster in United States history. [2] [3] [4]
National Commission on the BP Deepwater Horizon Oil Spill and Offshore Drilling begins two days of hearings at the Hilton New Orleans Riverside [109] July 15 – BP test cuts off all oil pouring into the Gulf at 2:25 pm.

At 1:15 p.m. the test on the new cap (effectively a smaller blowout preventer connected to the original damaged blowout preventer) closing the well begins. At 2:25 p.m. BP says that no flow of oil is going into the Gulf. A successful test will show constant pressure of 8000 to 9000 psi in the cap and the well could effectively stop the spill.
