BP is working to contain an out-of-control production well at the Prudhoe Bay oil field on the North Slope. The well is currently venting natural gas and has released at least some crude oil into the environment.
State regulators say they don’t yet know how serious the incident is, or what amount of oil or gas has been released.
In an emailed statement, BP said nobody was near the well at the time of the release, and there have been no injuries.
Regulators were still waiting for details Friday afternoon.
“It’s been spewing gas and some amount of crude, and some of it’s getting onto the surrounding tundra,” Dan Seamount said. He’s a commissioner with the Alaska Oil and Gas Conservation Commission. “We don’t have any volumes yet.”
Seamount said it’s been years since an incident like this took place on the North Slope. The drill site, DS2, is about five miles from the industry hub of Deadhorse.
On Friday afternoon, BP was working to depressurize the drill site to reduce the amount of gas venting from the well. Regulators said no workers were being allowed near the well until that happened, because of the fire hazard.
“When a well has lost control, it becomes unpredictable, and we want to make sure that the people that respond to the site do so in a safe way,” Ashley Adamczak, with the state Department of Environmental Conservation (ADEC) in Fairbanks, said.
Adamczak said once workers are able to approach the well, the company and regulators will be able to get a better sense of what caused the incident and how much oil and gas was released.
BP first noticed the release at about 7:30 a.m. Friday, according to a situation report from ADEC. The report said representatives of ADEC, EPA and the North Slope Borough would establish a unified command with BP to develop cleanup plans.
But as of 4 p.m. Friday, there was no word on when BP expected to have the well under control. Seamount said it could be hours, or days. The company hadn’t yet submitted a plan for shutting in the well to the Alaska Oil and Gas Conservation Commission for approval.
“It sounds like the problem is going to be taken care of,” Seamount said, adding after a pause: “Not sure when.”
