Formerly known as the Naval Petroleum Reserve No. 4, the National Petroleum Reserve in Alaska is now a vast 22.8-million acre area on Alaska's North Slope. In 1923, mindful of the land's conceivable petroleum value, President Harding set aside this area as an emergency oil supply for the U.S. Navy. In 1976, in accordance with the Naval Petroleum Reserves Production Act, the administration of the reserve was transferred to the Department of the Interior, more specifically the Bureau of Land Management, and was renamed to what is now known as the National Petroleum Reserve-Alaska (NPR-A).

Oil and gas leasing in the NPR-A is authorized under the Naval Petroleum Reserves Production Act of 1976 (42 U.S.C.6501 et seq.), as amended including the Department of the Interior and Related Agencies Appropriation Act of 1981 (94 Stat. 2964). Regulations for NPR-A oil and gas leasing, exploration and operations are found in 43 Code of Federal Regulations (CFR), Parts 3130, 3150, 3160, respectively. The Mineral Leasing Act of 1920, as amended and supplemented (30 U.S.C. 181 et seq.) and related regulations do not apply to leasing in the NPR-A.

NPR-A lease sales have been held by the BLM, in both the Northwest (NW) and Northeast (NE) Planning Areas.  Lease tracts were offered in the NE in 1999, 2002, and 2010, in the NW in 2004, and 2006.  In 2008 and 2011, lease tracts in both the NE and NW were offered.  A new Integrated Activity Plan/Environmental Impact Statement for the entire NPR-A was completed and the Record of Decision was signed in February of 2013.  The BLM will be holding annual oil and gas lease sales for the NPR-A.  The current list of leases can be found at NPR-A Oil & Gas Leases
