30 Years of Safe Operations
Offshore Alaska







Production began at Nikaitchuq in 2011. The 11-acre offshore artificial gravel island is located at Spy Island, about 2.8 miles from shore, in 10 feet of water. The facilities have been designed and built using technology aimed at minimizing the impact on the environment: zero flaring, pipe-in-pipe technology for hydrocarbon transportation, spill containment devices in all modules and low emission turbine generators.



Finished in 2008, Oooguruk is located in 4.5 feet of water about 5 miles offshore in Alaska’s Beaufort Sea. The field is expected to produce oil and gas for 25 to 30 years.

Liberty Project Location

Located 15 miles east of Prudhoe Bay in Foggy Island Bay, Liberty Island will sit about six miles offshore in 19 feet of water. The area is well protected from the moving polar icepack, shielded by a belt of offshore barrier islands and covered by stable “shore-fast” sea ice in winter.

The Development Plan

The development plan calls for construction of a self-contained island connected to land by a subsea pipeline. Other islands of this type were safely constructed and have been developing Alaska’s offshore resources responsibly for nearly 30 years: Endicott, Northstar, Oooguruk and Nikaitchuq.

The Liberty Project


The Liberty oilfield contains one of the largest potential sources of new light oil production on the North Slope, with an estimated 80-130 million barrels of recoverable oil. As the Liberty Unit Operator, Hilcorp Alaska LLC is currently pursuing all of the necessary permits and authorizations to develop the Liberty reservoir. Development of this resource will help offset declining light oil production on the North Slope and contribute to increasing the life span and efficiency of TAPS.

If the project is developed, peak production is estimated to be 60,000 barrels/day from a total of five production wells.
