Last night the team responding to the venting of gas from a well on Drill Site 2 of the Prudhoe Bay oil field succeeded in killing the well and thus achieving control of hydrocarbons escaping from the wellhead, BP spokeswoman Dawn Patience has told Petroleum News.
The venting of gas from the wellhead was discovered at 7:30 a.m. on April 14. Initially the gas leak also generated a spray of oil that impacted the well pad. BP set up a command post on the North Slope for the incident and ramped up an incident management team involving BP, the Alaska Department of Environmental Conservation, the Environmental Protection Agency and the North Slope Borough.
The response team determined that there were two leaks on the well: an oil leak near the top and another leak farther down. The sprayed oil had been coming from the top leak, which was stopped by activating the well's surface safety valve, according to an April 15 situation report from ADEC. BP says that all leakage from the well has now been stopped.
