BP working to control damaged oil in Alaska

Officials say a leak of natural gas at an oil well on Alaska's North Slope has been plugged.

The cause of the release remains unknown, as does the total amount of oil spilled by the leak.

Two leaks have been discovered as of Saturday afternoon, "The top leak was misting oil in conjunction with releasing natural gas", according to the report.

Anchorage-based BP Exploration Alaska Inc., a subsidiary of BP PLC, is the owner of the well in the Prudhoe Bay oil field.

The spokesperson Brett Clanton, from BP's official team present there said the crew members used infrared cameras to see the condition of the leakage, which is found to be not that severe. The authorities have not established yet, what prompted the well to discharge oil and gas.

A second leak at the well was emitting gas at a reduced rate, the state's environmental conservation department said.

BP reported the leak and formed a "unified command", which included responders from Alaska's Department of Environmental Conservation, the U.S. Environmental Protection Agency, and the North Slope Borough.

Responders determined the well had risen 3-4 feet, causing a pressure gauge to break off and preventing responders from pumping material into the well to kill it. Environmentalists, describing the well as "out of control", called on the state to investigate. This last March, daily output in the area hit 565,000 bpd - the highest in more than three years. The Coastal Plain of the Arctic National Wildlife Refuge also contains vast reserves of oil - as much as 16 billion recoverable barrels, by some estimates. Hilcorp Alaska has discovered several oil and natural-gas leaks in pipelines, but ice made had it impossible to fix the leaks. Alyeska was a joint partnership led by the North Slope's top producers, BP, Exxon Mobil and ConocoPhillips.
