Number: RL31573 Title: The National Petroleum Reserve-Alaska (NPRA) Authors: Robert L. Bamberger, Resources, Science and Industry Division Abstract: In May 2002, the United States Geological Survey (USGS) released revised estimates of the oil and gas resources that may lie beneath the surface of the National Petroleum Reserve Alaska (NPRA). Significantly higher than previous estimates, these numbers may be considered by the House and Senate conferees in their deliberations to reach agreement on a mutually acceptable energy bill. The House-passed version of omnibus energy legislation, H.R. 4, would allow oil and gas leasing in ANWR (limiting the footprint of development to 2,000 acres of the coastal plain). The Senate version contains no ANWR provision. This report provides a history of the NPRA and discusses the most recent estimates. Pages: 8 Date: Updated September 17, 2002
