Hilcorp Alaska Monday morning completed emptying a natural gas pipeline in Alaska’s Cook Inlet that is suspected of having a leak. The pipeline is at the Steelhead Platform, which produces natural gas from the Grayling Gas Sand Formation in the Trading Bay Unit on the west side of Cook Inlet. During an investigation prompted by natural gas pipeline leak discovered earlier this year in the Cook Inlet, a metering discrepancy was discovered on the pipeline serving the Steelhead Platform, Hilcorp said in a statement. “As a precaution, we started emptying the A Pipeline of natural gas on Saturday, and that process was completed early Monday morning,” the company said. “The line now contains filtered seawater. “We have decided to leave the line filled with seawater until a later time when we are able to further investigate and address the meter discrepancy.” A crude oil pipeline leak also was recently discovered by Hilcorp in the Cook Inlet.
