Development-Driller3

With a final shot of cement, BP Plc on Sep 19, 2010, permanently killed its deep-sea well in the Gulf of Mexico that ruptured on April 20. 153 days after the Macondo well ruptured, the BP succeeded in drilling a relief well nearly 18,000 feet below the ocean surface from the "Development Driller III" and permanently sealing the well with cement. The Macondo 252 well is effectively dead now and poses no more threat to the Gulf of Mexico. On Sep 16, a relief well bored into the bottom of the Macondo well to pump in cement and seal the reservoir for good. BP pumped cement for seven hours on Sep 17, and finished a pressure test early on Sep 19 that showed the well was permanently clogged. The development provided an end to the disaster nearly five months after the well ruptured on April 20, causing an explosion aboard the “Deepwater Horizon” drilling rig that killed 11 workers and spewed more than 4 million barrels of oil into the sea.
