Constraining the Age and Magnitude of Uplift in the Northern NPRA

USGS Publication: U.S. Geological Survey Professional Paper 1784-A
A broad, post-mid-Cretaceous uplift is defined in the northern National Petroleum Reserve in Alaska (NPRA) by regional truncation of Cretaceous strata, thermal maturity patterns, and amounts of exhumation estimated from sonic logs. Apatite fission-track (AFT) analysis of samples from three wells (South Meade No. 1, Topagoruk No. 1, and Ikpikpuk No. 1) across the eastern flank of the uplift indicates Tertiary cooling followed by Quaternary heating.

2010 Petroleum Resource Assessment of the National Petroleum Reserve in Alaska

GIS Play Maps

USGS Publication: Open-File Report 2011–1099
This report provides digital geographic information systems (GIS) files of maps for each of the 24 plays considered in the U.S. Geological Survey (USGS) 2010 updated petroleum resource assessment of the National Petroleum Reserve in Alaska (NPRA) (Houseknecht and others, 2010). These are the sample plays evaluated in a previous USGS assessment of the NPRA (Bird and Houseknecht, 2002a), maps of which were released in pdf format (Bird and Houseknecht, 2002b).

2010 Updated Assessment of Undiscovered Oil and Gas Resources of the NPRA

Press Release & Publication
"These new findings underscore the challenge of predicting whether oil or gas will be found in frontier areas and the importance of analyzing the geologic characteristics and history of an area in order to understand the oil and gas resources,” explains USGS Director, Dr. Marcia McNutt.


National Petroleum Reserve
in Alaska (NPRA)

The National Petroleum Reserve in Alaska (NPRA) has been the focus of oil exploration during the past decade, stimulated by the mid-1990s discovery of the adjacent Alpine field—the largest onshore oil discovery in the United States during the past 25 years. Recent activities in NPRA, including extensive 3–D seismic surveys, six Federal lease sales totaling more than $250 million in bonus bids, and completion of more than 30 exploration wells on Federal and Native lands, indicate in key formations more gas than oil and poorer reservoir quality than anticipated. In the absence of a gas pipeline from northern Alaska, exploration has waned and several petroleum companies have relinquished assets in the NPRA.
