How long did it take to stop the well from blowing out in the gulf of Mexico?

The Deepwater Horizon oil spill in the Gulf of Mexico, which began on April 20, 2010, took several months to contain. The well was successfully capped on July 15, 2010, after various attempts to stop the flow of oil, including the use of a containment dome and a "top kill" procedure. Ultimately, it took approximately 87 days to fully stop the blowout and seal the well.
