Deepwater Horizon – BP Gulf of Mexico Oil Spill
On April 20, 2010, the oil drilling rig Deepwater Horizon, operating in the Macondo Prospect in the Gulf of Mexico, exploded and sank resulting in the death of 11 workers on the Deepwater Horizon and the largest spill of oil in the history of marine oil drilling operations. Approximately 4.9 billion barrels of oil flowed from the damaged Macondo well over an 87-day period, before it was finally capped on July 15, 2010. On December 15, 2010, the United States filed a complaint in District Court against BP Exploration & Production and several other defendants alleged to be responsible for the spill.
