Workers relieve pressure on leaking Alaska oil well

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.

But the release of vented natural gas means that the well is still leaking methane, a potent greenhouse gas that traps heat 86 times more effectively than carbon dioxide over a 20-year period, into the atmosphere.

The well is too risky at this time for a response team made up of state and federal energy officials and BP employees to get near the well.

The network said other quantities of natural gas were leaking from the site along with crude oil and investigations were underway to find out the causes of the accident.

BP had a 201,000-gallon oil spill in March 2006 and a smaller spill five months later that ultimately caused it to halve production at Alaska's Prudhoe Bay for several weeks.

United Kingdom oil giant BP has been engaged in controlling a damaged oil well on Alaska's remote North Slope over the weekend, after the well started venting natural gas vapours on Friday morning, according to the company and Alaska officials.

On Friday morning, leaks were discovered in the well due to which the spray of crude oil was stopped. All the excess pressure was removed from the well to keep it in a safe range of pressure.

Alaskan and federal officials had identified two leaks spewing methane gas which is linked to climate change. Workers contained that leak by activating a safety valve.

Officials say the initial oil release may have affected an area of about 1½ acres.

An unknown about of oil reached the well pad.

Alaska Department of Environmental Conservation spokeswoman Candice Bressler says the well operated by BP Exploration Alaska Inc., a subsidiary of BP, was successfully controlled overnight. This was found by the statement of the Environmental Conservation Department of the state.
