Map of assessed continuous (unconventional) oil resources in the United States, 2014

USGS Publication: Digital Data Series 69-JJ
​Since 2000, the USGS has completed assessments of continuous (unconventional) resources in the United States based on geologic studies and analysis of well-production data and has compiled digital maps of the assessment units classified into four categories: shale gas, tight gas, coalbed gas, and shale oil or tight oil (continuous oil).

Petroleum Systems and Assessment of Undiscovered Oil and Gas in the Anadarko Basin Province, Colorado, Kansas, Oklahoma, and Texas—USGS Province 58

USGS Publication: Digital Data Series 69-EE
​This publication provides research results and related data in support of the U.S. Geological Survey assessment of the undiscovered oil and gas resource potential of the Anadarko Basin Province of western Oklahoma and Kansas, northern Texas, and southeastern Colorado. This province area includes the Las Animas arch of southeastern Colorado, part of the Palo Duro Basin of Texas, and the Anadarko Basin.

Map of assessed coalbed-gas resources in the United States, 2014

USGS Publication: Digital Data Series 69-II
This report presents a digital map of coalbed-gas resource assessments in the United States as part of the U.S. Geological Survey’s (USGS) National Assessment of Oil and Gas Project. Using a geology-based assessment methodology, the USGS quantitatively estimated potential volumes of undiscovered, technically recoverable natural gas resources within coalbed-gas assessment units (AUs).

Map of Assessed Tight-Gas Resources in the United States, 2014

National Assessment of Oil and Gas Project

USGS Publication: Digital Data Series DDS–69–HH
This report presents a digital map of tight-gas resource assessments in the United States as part of the USGS National Assessment of Oil and Gas Project. Using a geology-based assessment methodology, the USGS quantitatively estimated potential volumes of undiscovered, technically recoverable natural gas resources within tight-gas assessment units (AUs). This is the second digital map product in a series of USGS unconventional oil and gas resource maps.

Upper Devonian-Mississippian stratigraphic framework of the Arkoma Basin

Upper Devonian-Mississippian stratigraphic framework of the Arkoma Basin and distribution of potential source-rock facies in the Woodford–Chattanooga and Fayetteville–Caney shale-gas systems

Outside Publication: AAPG Bulletin
Wireline logs were used to document the stratigraphic framework of Upper Devonian–Mississippian strata in the Arkoma Basin, and maps of high-gamma ray (HGR) log response were used to analyze the spatial distribution of potential source rocks in the Woodford–Chattanooga and Fayetteville–Caney shale-gas systems...

The Devonian Marcellus Shale and Millboro Shale

Outside Publication: GSA Field Guides 35, 2014
This field trip will examine a number of natural and engineered exposures in the vicinity of the West Virginia–Virginia state line, where participants will have the opportunity to view a variety of sedimentary facies within the Marcellus shale itself, sedimentary structures, tectonic structures, fossils, overlying and underlying formations, volcaniclastic ash beds, and to view a basaltic intrusion.

Map of Assessed Shale Gas in the United States, 2012

National Assessment of Oil and Gas Project

USGS Publication: Digital Data Series DDS–69–Z
The U.S. Geological Survey has compiled a map of shale-gas assessments in the United States that were completed by 2012 as part of the National Assessment of Oil and Gas Project. Using a geology-based assessment methodology, the U.S. Geological Survey quantitatively estimated potential volumes of undiscovered gas within shale-gas assessment units. These shale-gas assessment units are mapped, and square-mile cells are shown to represent proprietary shale-gas wells. The square-mile cells include gas-producing wells from shale intervals. ...

Coalbed Natural Gas Exploration, Drilling Activities, and Geologic Test Results

2007–2010, in Wainwright, Alaska

USGS Publication: Open-File Report 2014–1004
The U.S. Geological Survey, in partnership with the U.S. Bureau of Land Management, the North Slope Borough, and the Arctic Slope Regional Corporation conducted a four-year study designed to identify, define, and delineate a shallow coalbed natural gas (CBNG) resource with the potential to provide locally produced, affordable power to the community of Wainwright, Alaska.

Overview

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.
