BPXA reports that approximately 1.4 million standard cubic feet of natural gas and an estimated 10 – 30 barrels (420 – 1260 gallons) of crude oil were released as a mist. The mist settled onto the manifold building, pipes, tanks, and snow at Drill Site 14 (DS-14).
The source of the spill is a weld failure in an artificial lift line that transports pressurized natural gas to Drill Site 14 for injection.
