Article Thumbnail Image 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...

Article Thumbnail Image 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. The estimate of...

Article Thumbnail Image 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...

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.
