On Friday morning, leaks were discovered in the well due to which the spray of crude oil was stopped. They still don't know what caused the spill.
In 2010, a BP well became the site of the worst offshore oil spill in USA history.
"BP is in the process of shutting in a well at the Prudhoe Bay oil field that experienced an unplanned release of hydrocarbon", said Brett Clanton, a BP spokesman in Houston. The oil spray ended Saturday, but the well remained out of control and vented gas through the weekend. But the continuing natural gas leak continues to be a problem.
According to the Environment Protection Agency who made a statement on the current gas leakage on this remote locate in Deadhorse, Alaska, which says the petroleum giant BP who is conducting the drilling on this oil well found a crack on the wellhead.
The total amount of oil spilled and whether the crude affected the snow-covered tundra nearby isn't yet clear, though authorities have expressed confidence the crude contamination is contained with a gravel area directly surrounding the well site. BP was fined $255 million by the state of Alaska for negligence in their maintenance of Prudhoe Bay pipelines.
North Slope production rose to 565,000 barrels a day in March, its highest level since December 2013. The Alaska Department of Environmental Conservation (DEC) says employees discovered the "uncontrolled gas release" from the top of a well house at 7:30 a.m. Friday. So far there have been no reports of impacts to wildlife.
"Responders determined that the well had 'jacked up, ' or risen, approximately 3 - 4 feet; this vertical movement of the well caused the pressure gauge to break off and prevented operations from pumping into the well to kill it", ADEC reported.
BP Exploration Alaska Inc. operates a well in the frigid North Slope of Alaska. The deadly Deepwater Horizon accident in the Gulf of Mexico forced BP to sell billions of dollars in assets and set aside more than $50 billion to pay for damages.
