Bakken and New Three Forks Oil and Gas Assessment

USGS Releases Updated Bakken and New Three Forks Oil and Gas Assessment

Press Release & Publication
Using a geology-based assessment methodology, the USGS estimated mean undiscovered volumes of 7.4 billion barrels of oil, 6.7 trillion cubic feet of natural gas, and 0.53 billion barrels of natural gas liquids in the Bakken and Three Forks Formations in the Williston Basin Province of Montana, North Dakota, and South Dakota.

Role of Stranded Gas in Increasing Global Gas Supplies

USGS Publication: Open-File Report 2013–1044
This report synthesizes the findings of three regional studies in order to evaluate, at the global scale, the contribution that stranded gas resources can make to global natural gas supplies. Stranded gas, as defined for this study, is natural gas in discovered conventional gas and oil fields that is currently not commercially producible for either physical or economic reasons. The regional studies evaluated the cost of bringing the large volumes of undeveloped gas in stranded gas fields to selected markets.

Coal Beds and Bedrock Geology Maps, Central Powder River Basin, Wyoming

Map Showing Principal Coal Beds and Bedrock Geology of the Ucross-Arvada Area, Central Powder River Basin, Wyoming

USGS Publication: Scientific Investigations Map 3240
The Ucross-Arvada area is part of the Powder River Basin, a large, north-trending structural depression between the Black Hills on the east and the Bighorn Mountains on the west. Almost all of the study area is within Sheridan and Johnson Counties, Wyoming.

Map of Assessed Shale Gas in the United States, 2012

USGS Publication: Digital Data Series DDS–69–Z
The USGS 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

Simplified Stratigraphic Cross Sections of the Eocene Green River Formation

Simplified Stratigraphic Cross Sections of the Eocene Green River Formation in the Piceance Basin, Northwestern Colorado

USGS Publication: Open-File Report 2013–1012
Thirteen stratigraphic cross sections of the Eocene Green River Formation in the Piceance Basin of northwestern Colorado are presented in this report. Originally published in a much larger and more detailed form by Self and others (2010), they are shown here in simplified, page-size versions that are easily accessed and used for presentation purposes.

The effect of coal bed dewatering and partial oxidation on biogenic methane potential

Outside Publication: International Journal of Coal Geology
Coal formation dewatering at a site in the Powder River Basin was associated with enhanced potential for secondary biogenic methane determined by using a bioassay. We hypothesized that dewatering can stimulate microbial activity and increase the bioavailability of coal. We analyzed one dewatered and two water-saturated coals to examine possible ways in which dewatering influences coal bed natural gas biogenesis by looking at differences with respect to the native coal microbial community, coal-methane...

Energy Map of Southwestern Wyoming

Energy data archived, organized, integrated, and accessible

USGS Publication: General Information Product 145
The Wyoming Landscape Conservation Initiative (WLCI) focuses on conserving world-class wildlife resources while facilitating responsible energy development in southwestern Wyoming. To further advance the objectives of the WLCI long-term, science-based effort, a comprehensive inventory of energy resource and production data is being published in two parts.

Coal Fields of the Conterminous United States

National Coal Resource Assessment Updated Version

USGS Publication: Open-File Report 2012–1205
This map sheet with accompanying Geographic Information System (GIS) project is an update of the existing U.S. Geological Survey (USGS) Conterminous U.S. Coal Fields map. This update was compiled using data primarily from the USGS National Coal Resource Assessment (NCRA) and information from other published maps.

Assessment of Undiscovered Oil and Gas Resources in the San Juan Basin Province

Total Petroleum Systems and Geologic Assessment of Undiscovered Oil and Gas Resources in the San Juan Basin Province, Exclusive of Paleozoic Rocks, New Mexico and Colorado

USGS Publication: Digital Data Series 69–F
In 2002, the USGS estimated undiscovered oil and gas resources that have the potential for additions to reserves in the San Juan Basin Province, New Mexico and Colorado. Paleozoic rocks were not appraised. The last oil and gas assessment for the province was in 1995. There are several important differences between the 1995 and 2002 assessments. The area assessed is smaller than that in the 1995 assessment. This assessment of undiscovered hydrocarbon resources in the San Juan Basin Province also used a slightly different approach in the assessment, and hence a number of the plays defined in the 1995 assessment are addressed differently in this report.
