How did bp stop the oil spill?

The oil spill is the result of a well blowout and unfortunately, we still do not have all the answers as to why the well blew out. It was a known "gassy" reservoir of oil, so it could be explained, as some suggest, by a large bubble of methane gas rushing out of the drill pipe, igniting and exploding. The explosion in April 2010 killed 11 people working on the rig.

Because of the fire or the explosion, a wellhead was damaged, the drilling rig collapsed breaking the piping that connected the drill to the well approximately 5000 ft below sea level, which allowed oil to begin to flow directly into the ocean. The fail safes that are supposed to protect the environment and people in this type of situation failed, or were inadequate under the deep well conditions.

Halliburton had finished cementing in a production casing and abnormal pressures were detected in the marine riser. But until more information is revealed, the cause is still speculative. Many more details should be available after a full inquiry is made.
