Press Release & PublicationIn 2011, the USGS completed an assessment of the undiscovered oil and gas potential of the Devonian Marcellus Shale within the Appalachian Basin Province of the eastern United States. The Marcellus Shale contains about 84 trillion cubic feet of undiscovered, technically recoverable natural gas and 3.4 billion barrels of undiscovered, technically recoverable natural gas liquids according to the new assessment.

USGS Publication: Open-File Report 2011–1167The U.S. Geological Survey (USGS) has developed a revised quantitative methodology for assessing resources in continuous (unconventional) petroleum deposits. Continuous petroleum resources include shale gas, coalbed gas, and other oil and gas deposits in low-permeability (“tight”) reservoirs.

The U.S. Geological Survey (USGS) compiled a geographic information system (GIS) of Wyoming statewide historical oil and gas drilling activity for the Wyoming Landscape Conservation Initiative (WLCI). This product complements the 2009 USGS publication on oil and gas development in southwestern Wyoming by approximating, based on database attributes, the time frame of drilling activity for each well (start and stop dates).

USGS Publication: Open-File Report 2011–1175Gas, oil, and water production data were compiled from selected wells in two tight gas reservoirs—the Codell-Niobrara interval, comprised of the Codell Sandstone Member of the Carlile Shale and the Niobrara Formation; and the Dakota J interval, comprised mostly of the Muddy (J) Sandstone of the Dakota Group; both intervals are of Cretaceous age—in the Wattenberg field in the Denver Basin of Colorado.

USGS Publication: Fact Sheet 2011–3046Using a geology-based assessment methodology, the U.S. Geological Survey estimated means of 957 million barrels of undiscovered oil, 3.6 trillion cubic feet of undiscovered natural gas, and 363 million barrels of undiscovered natural gas liquids in the Austin Chalk and Tokio and Eutaw Formations in onshore lands and State waters of the Gulf Coast.

Press Release & Publication
The Cook Inlet Region of Alaska contains an estimated mean of 19 trillion cubic feet of natural gas, about 600 million barrels of oil, and 46 million barrels of natural gas liquids, according to a new assessment by the U.S. Geological Survey.

Press Release & PublicationUSGS 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).

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).

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.
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.
