How did they close the Deepwater Horizon oil spill?

On July 15, 2010, BP announced that it had successfully plugged the oil leak using a tightly fitted cap. The cap, weighing 75 tons and standing 30 feet (9.1 m) high, is now bolted to the failed blowout preventer. It consists of a Flange Transition Spool and a 3 Ram Stack and is a temporary solution.

What are the methods of separating oil spills?

To separate immiscible oil–water mixtures, traditional physical methods, such as gravity separation, centrifuge, sedimentation and hydrocyclone separation, are widely used [2,4,7]. These methods are either time-consuming or energy intensive.

How long did the oil flow before it was capped off?

A roller coaster ride of confusion and turmoil followed the BP Deepwater Horizon rig explosion and spill, which lasted an unimaginable 87-days. Finally, on July 15, 2010, the spewing well 5,000 feet deep in the Gulf of Mexico was capped at last.
