Press Release & Publication
USGS asked to conduct an initial, independent evaluation of the science needs that would inform the Administration’s consideration of the right places and the right ways in which to develop oil and gas resources in the Arctic Outer Continental Shelf (OCS). The USGS developed more than 50 findings and an equal number of recommendations in the course of the examination of these topics. Specific and detailed scientific information, key knowledge gaps, and recommendations are presented in Holland-Bartels and Pierce (2011).

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).

Press Release & Publication
The U.S. Geological Survey assessment on the economic recoverability of undiscovered, conventional oil and gas resources within the National Petroleum Reserve in Alaska (NPRA) and adjacent state waters is now available online.

For the largest producing natural gas fields in the onshore Gulf of Mexico Basin, the relation between temperature versus depth was investigated. Prolific natural gas reservoirs with the highest temperatures were found in the Upper Cretaceous downdip Tuscaloosa trend in Louisiana.

The USGS assessed both undiscovered technically recoverable conventional oil and gas and continuous (unconventional) coalbed gas in the Western Oregon and Washington Province, resulting in an estimated total mean of 2.2 trillion cubic feet of gas and a mean of 15 million barrels of oil.

Using a geology-based assessment methodology, the U.S. Geological Survey estimated means of 147.4 trillion cubic feet of undiscovered natural gas, 2.4 billion barrels of undiscovered oil, and 2.96 billion barrels of undiscovered natural gas liquids in Jurassic and Cretaceous strata in onshore lands and State waters of the Gulf Coast.

AAPG Datapages and the GIS Publications Committee wish to thank Janet Pitman and the United States Geological Survey for allowing the Reservoirs and Petroleum Systems of the Gulf Coast map to be posted on GIS-UDRIL's Open Files page, thereby making it available to the public as a free download.

The U.S. Geological Survey, using a geoscience-based assessment methodology, estimated mean technically-recoverable undiscovered continuous and conventional resources that total 495 million barrels of oil, 27.5 trillion cubic feet of natural gas, and 410 million barrels of natural gas liquids.

Valley-fill deposits form a significant class of hydrocarbon reservoirs in many basins of the world. Maximizing recovery of fluids from these reservoirs requires an understanding of the scales of fluid-flow heterogeneity present within the valley-fill system.
