National Petroleum Reserve in Alaska

Land status map of the National Petroleum-Reserve Alaska

BLM-Alaska manages 22.8 million acres of surface and subsurface estate in the National Petroleum Reserve-Alaska (NPR-A) on Alaska’s North Slope. It is nearly the size of Indiana and is the largest single block of federally managed land in the United States. Based on the Oct. 2010 U.S. Geological Survey for NPR-A, this area contains an estimated 896 million barrels of technically recoverable oil and 52.8 trillion cubic feet of natural gas. A Record of Decision for the NPR-A Final Integrated Activity Plan/Environmental Impact Statement was issued in Feb. 2013 which provides key objectives to implement consistent management direction for the entire NPR-A.

Under the Naval Petroleum Reserves Production Act of 1976, the BLM is required to balance the exploration and development of oil & gas resources with the protection of wildlife, habitat, and the subsistence values of rural residents and Alaska Natives.
