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.

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...

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.

Drill Hole Data for Coal Beds in the Powder River Basin, Montana and Wyoming

USGS Publication: Data Series 713
This report by the USGS of the Powder River Basin (PRB) of Montana and Wyoming is part of the U.S. Coal Resources and Reserves Assessment Project. Essential to that project was the creation of a comprehensive drill hole database that was used for coal bed correlation and for coal resource and reserve assessments in the PRB. This drill hole database was assembled using data from the USGS National Coal Resources Data System, several other Federal and State agencies, and selected mining companies.

Assessment of Coal in the Powder River Basin, Wyoming and Montana

Assessment of Coal Geology, Resources, and Reserve Base in the Powder River Basin, Wyoming and Montana

USGS Publication: Fact Sheet 2012–3143
Using a geology-based assessment methodology, the U.S. Geological Survey estimated in-place resources of 1.07 trillion short tons of coal in the Powder River Basin, Wyoming and Montana. Of that total, with a maximum stripping ratio of 10:1, recoverable coal was 162 billion tons.

Assessment of Coal Geology, Resources, and Reserves in the Montana Powder River Basin

Assessment of Coal Geology, Resources, and Reserves in the Montana Powder River Basin

USGS Publication: Open-File Report 2012–1113
The purpose of this report is to summarize geology, coal resources, and coal reserves in the Montana Powder River Basin assessment area in southeastern Montana. This report represents the fourth assessment area within the Powder River Basin to be evaluated in the continuing USGS. See Press Release for listing of all related publications.

New Powder River Basin-Wide Coal Assessment of Recoverable Resources and Reserves

Press Release & Related Publications

The Powder River Basin of Wyoming and Montana contains about 162 billion short tons (BST) of recoverable coal from a total of 1.07 trillion short tons of in-place resources according to a new USGS assessment. This assessment also estimates that 25 BST of those resources are currently economical.

Database of the United States Coal Pellet Collection of the U.S. Geological Survey Organic Petrology Laboratory

USGS Publication: Open-File Report 2012–1151
The Organic Petrology Laboratory (OPL) of the U.S. Geological Survey (USGS) Eastern Energy Resources Science Center in Reston, Virginia, contains several thousand processed coal sample materials that were loosely organized in laboratory drawers for the past several decades.

Powder River Basin, Wyoming Coal Assessment

In 2009, the USGS completed the first digital National Coal Resource Assessment (NCRA) of in-place coal resources. The current generation of U.S. coal assessments will not only be a refinement of the coal resources, but also the systematic determination of the regional coal reserve base in all the major coal provinces in the U.S. The reserve base provides not only estimates of coal resources that are...

currently economic (reserves), but what may become economic with current technologies (recoverable resources), which is important from a national energy security and policy standpoint. The first U.S. coal basin to be evaluated in this new assessment phase is the Powder River Basin, WY (PRB). The PRB is the single most important coal basin in the U.S. production-wise, supplying over 42 percent of the total coal produced in the U.S. in 2012.

National Coal Resource Assessment

The National Coal Resource Assessment (NCRA) project was a multi-year effort by the U.S. Geological Survey (USGS) Energy Program to identify, characterize, and assess the coal resources that will supply a major part of the Nation’s energy needs during the next few decades. NCRA data and publications are available on the NCRA Powder River Basin page.
