BOEM releases Hilcorp's Liberty development plan for public
The U.S. Bureau of Ocean Energy Management released the Hilcorp Alaska development plan for the Liberty offshore oil field on Friday.
A 60-day public comment period began with the release as one of the initial steps in a multi-year permitting process.
According to Hilcorp’s filing, Liberty is the largest delineated but undeveloped light oil reservoir on the North Slope. It is located about 5 miles offshore in Foggy Bay where the water is about 19 feet deep. Hilcorp proposes to construct a gravel island and transport oil to shore via an underwater pipeline that will connect to the existing Badami pipeline and from there to the Trans-Alaska Pipeline System.
At peak production, Hilcorp estimates 60,000 to 70,000 barrels per day and that the reservoir holds between 80 million and 150 million barrels of oil. The company estimates it will take two years to reach peak production.
According to Hilcorp’s proposed development plan, a record of decision in September 2017 would allow for the project to begin that winter, with first oil coming in the first quarter of 2020.
Hilcorp acquired 50 percent of Liberty from BP last November, along with three other North Slope properties. BP previously submitted a development plan for Liberty that would have used extended reach drilling from onshore to reach the field, but withdrew that plan in November 2012.
