BP Deepwater Horizon Well – Five Years Later

April 20, 2010, Methane gas blew out from a wellhead a mile below the Gulf of Mexico.  At a Pressure 150 times greater than air at the Earth’s surface, the gas shot up through a drilling riser to the Deepwater Horizon oil platform and platform and exploded, killing 11 workers.

Fire raged 87 days, spilling 2.5 million gallons of crude oil per day.

It was the worst offshore oil spill in history. It continued to gush oil for 87 days, spilling 200 million gallons ( 2.5 million gallons per day) of crude spilling crude oil in a four-dimension disaster that reached from the Gulf’s floor to the its surface, and its seashore.

What happened to all the oil? Some of it was burned off, some of it was skimmed up and also applied chemical dispersants used to break up some of it so that it would either dissipate, become soluble or be small enough for microbes to eat. But 5 years later, up to 10 percent remains in marshes and anywhere from 3 to 30 percent – though 10 percent is probably a good estimate – is on the ocean floor.   We discussed in class the numerous factors that are involved in this disaster and its effects and the clean up.
