USGS Publication: Fact Sheet 2012–3051
The U.S. Geological Survey (USGS) recently completed an estimate of technically recoverable, conventional oil in selected oil fields in the Permian Basin in west Texas and southeastern New Mexico. The mean total volume of potential additional oil resources that might be added using improved oil-recovery technologies was estimated to be about 2.7 billion barrels of oil.

USGS Publication: Fact Sheet 2012–3031
Using a geology-based assessment methodology, the U.S. Geological Survey estimated means of 560 million barrels of undiscovered oil, 12,701 billion cubic feet of undiscovered natural gas, and 490 million barrels of undiscovered natural gas liquids in the Paradox Basin of Utah, Colorado, New Mexico, and Arizona.

Press Release & Publication
The U.S. Geological Survey estimated potential, technically recoverable oil and gas resources for source rocks of the Alaska North Slope. Estimates (95-percent to 5-percent probability) range from zero to 2 billion barrels of oil and from zero to nearly 80 trillion cubic feet of gas.

USGS Publication: Digital Data Series 69–W
Using a geology-based assessment method, the U.S. Geological Survey estimated mean undiscovered volumes of 3.8 billion barrels of undiscovered oil, 3.7 trillion cubic feet of associated/dissolved natural gas, and 0.2 billion barrels of undiscovered natural gas liquids in the Williston Basin Province, North Dakota, Montana, and South Dakota. This is the data series for the assessment.

USGS Publication: Fact Sheet 2012–3003
Using a geology-based assessment methodology, the U.S. Geological Survey assessed means of (1) 141 million barrels of oil (MMBO), 502 billion cubic feet of natural gas (BCFG), and 16 million barrels of natural gas liquids (MMBNGL) in the conventional Eagle Ford Updip Sandstone Oil and Gas Assessment Unit (AU); (2) 853 MMBO, 1,707 BCFG, and 34 MMBNGL in the continuous Eagle Ford Shale Oil AU; and (3) 50,219 BCFG and 2,009 MMBNGL in the continuous Eagle Ford Shale Gas AU in onshore lands and State waters of the Gulf Coast.

USGS Publication: Open-File Report 2011–1237
In the Cook Inlet region, the USGS estimates mean undiscovered volumes of nearly 600 million barrels of oil, about 19 trillion cubic feet of gas, and about 46 million barrels of natural gas liquids.

USGS Publication: Open-File Report 2011–1298
The USGS recently assessed the potential for natural gas resources in the Middle Devonian Marcellus Shale of the Appalachian Basin Province. This preliminary report provides some additional geologic information used in the Marcellus Shale assessment.

USGS Publication: Scientific Investigations Report 2011–5163A new U.S. Geological Survey method was developed to assess the reserve-growth potential of technically recoverable crude oil and natural gas to be added to reserves under proven technology currently in practice within the trend or play, or which reasonably can be extrapolated from geologically similar trends or plays. This method currently is in use to assess potential additions to reserves in discovered fields of the United States.

Outside Publication: Geological and Mining Institute of Spain, Boletín Geológico y Minero
USGS paper published in the Geological and Mining Institute of Spain, Boletín Geológico y Minero. New experimental methodology for assessing continuous gas resources is illustrated by evaluating a gas play in the Woodford Shale in the Arkoma Basin of Oklahoma.
The USGS Energy Resources Program provides periodic assessments of the oil and natural gas endowment of the United States. New, prioritized, assessment results, as part of the Energy Policy and Conservation Act (EPCA) and the current National Assessment are shown above. Additional EPCA and priority basin assessment results will be posted as they become available.
