Hilcorp’s line, which delivers fuel gas to a system of oil platforms in the inlet, sprung a leak last month.
The last time the pipe leaked, in 2017, Hilcorp didn’t complete repairs for three months, citing danger from ice in the inlet.
The leak was initially estimated to have released some 210,000 gallons of crude. Federal investigators say that they now have an “unconfirmed lower spill estimate,” without specifying how much.

Regulators say an oil leak could cause much more environmental damage than the current natural gas leak. Both pipelines run through key habitat for endangered beluga whales.
State regulators have given preliminary approval to Hilcorp’s plan to monitor the environmental impacts of the gas leak in Cook Inlet.
An ongoing natural gas leak in Cook Inlet is sparking a debate over pipeline safety. Hilcorp says it can’t shut off the flow of gas through the pipeline without risking an oil spill, but a number of environmental groups disagree.
Hilcorp recently informed state regulators that the company is unlikely to begin repairs on a gas leak in Cook Inlet until mid- to late March, according to a letter obtained by Alaska’s Energy Desk through a public records request.
The leak from an underground pipeline in north-central Iowa was first discovered in a field on Wednesday morning. Crews for the company, Magellan Midstream Partners, are working to clean it up.
A crude oil pipeline in western North Dakota has leaked nearly 200,000 barrels of oil. The scene is about 150 miles west of where protesters have been fighting the Dakota Access pipeline.
