Appalachian Basin Oil and Gas Assessments
Science Center Objects
The USGS has conducted numerous assessments of undiscovered oil and gas in the Appalachian Basin, including studies of the Marcellus Shale. The region extends from Alabama to Maine. The following is an overview of the assessments:
- 2019 Ordovician Point Pleasant Formation and Utica Shale (FS 2019-3044)
- 2019 Middle Devonian Marcellus Shale (FS 2019-3050)
- 2016 Sunbury and Chattanooga Shale (Factsheet)
- 2012 Utica Shale (Factsheet)
- 2011 Marcellus Shale (Factsheet, Open File Report)
- 2008 Utica-Lower Paleozoic TPS (Factsheet)
- 2006 Devonian Shale-Middle and Upper Paleozoic TPS (Open File Report)
- 2002 Assessment of Appalachian Basin (Factsheet)
- 2002 Carboniferous Coal-Bed Gas (Factsheet, Open File Report)
- 1995 Assessment of Appalachian Basin

Assessment of undiscovered oil and gas resources of the Ordovician Utica Shale of the Appalachian Basin Province, 2012
The U.S. Geological Survey assessed unconventional oil and gas resources of the Upper Ordovician Utica Shale and adjacent units in the Appalachian Basin Province. The assessment covers parts of Maryland, New York, Ohio, Pennsylvania, Virginia, and West Virginia. The geologic concept is that black shale of the Utica Shale and adjacent units...

Assessment of undiscovered oil and gas resources of the Devonian Marcellus Shale of the Appalachian Basin Province
Using a geology-based assessment methodology, the U.S. Geological Survey (USGS) estimated a mean undiscovered natural gas resource of 84,198 billion cubic feet and a mean undiscovered natural gas liquids resource of 3,379 million barrels in the Devonian Marcellus Shale within the Appalachian Basin Province. All this resource occurs in continuous...

Assessment of Appalachian Basin Oil and Gas Resources: Utica-Lower Paleozoic Total Petroleum System
The Utica-Lower Paleozoic Total Petroleum System (TPS) is an important TPS identified in the 2002 U.S. Geological Survey (USGS) assessment of undiscovered, technically recoverable oil and gas resources in the Appalachian basin province (Milici and others, 2003). The TPS is named for the Upper Ordovician Utica Shale, which is the primary source...
Ryder, Robert T. Assessment of Appalachian basin oil and gas resources:Devonian shale - Middle and Upper Paleozoic Total Petroleum System
The U.S. Geological Survey (USGS) recently completed an assessment of the technically recoverable undiscovered hydrocarbon resources of the Appalachian Basin Province. The assessment province includes parts of New York, Pennsylvania, Ohio, Maryland, West Virginia, Virginia, Kentucky, Tennessee, Georgia and Alabama. The assessment was based on six...

Undiscovered oil and gas resources underlying the U.S. portions of the Great Lakes, 2005
The U.S. Geological Survey (USGS) completed an assessment of the undiscovered oil and gas potential of the U.S. portions of the Appalachian Basin and the Michigan Basin in 2002 and 2004, respectively. Following the assessments of these two basins, oil and gas allocations were assigned to the U.S. portions of the Great Lakes - Lake Superior (...

Assessment of undiscovered carboniferous coal-bed gas resources of the Appalachian Basin and Black Warrior Basin provinces, 2002
Milici, Robert C.; Hatch, Joseph R. Assessment of Appalachian Basin Oil and Gas Resources: Carboniferous Coal-bed Gas Total Petroleum System
The Carboniferous Coal-bed Gas Total Petroleum System, lies within the central and northern parts of the Appalachian coal field. It consists of five assessment units (AU): the Pocahontas Basin in southwestern Virginia, southern West Virginia, and eastern Kentucky, the Central Appalachian Shelf in Tennessee, eastern Kentucky and southern West...

Assessment of Undiscovered Oil and Gas Resources of the Appalachian Basin Province, 2002
Using a geology-based assessment methodology, the U.S. Geological Survey estimated a mean of 70.2 trillion cubic feet of undiscovered natural gas, a mean of 54 million barrels of undiscovered oil, and a mean of 872 million barrels of undiscovered natural gas liquids in the Appalachian Basin Province.

Digital map data, text, and graphical images in support of the 1995 National assessment of United States oil and gas resources
This CD-ROM contains files in support of the 1995 USGS National assessment of United States oil and gas resources (DDS-30), which was published separately and summarizes the results of a 3-year study of the oil and gas resources of the onshore and state waters of the United States. The study describes about 560 oil and gas plays in the United...

1995 National assessment of United States oil and gas resources
The purpose of the National Oil and Gas Resource Assessment Project is to develop a set of scientifically based hypotheses concerning the quantities of oil and gas that could be added to the measured (proved) reserves of the United States. The word assessment sometimes has the connotation of an inventory. But this is not the case in this...
