The coal mines in the Powder River Basin produce about 40% of the nation's thermal coal, but production volumes have been declining for years. Natural gas and renewable energy have gradually ...
Subbituminous coal is the predominant rank of coal produced west of the Mississippi River, accounting for 62 percent of the region's total coal output in 1992. Subbituminous coal in Wyoming's Powder River Basin, the principal source of this rank of coal, has an emission factor of pounds of carbon dioxide per million Btu.

The first coal basin to be evaluated was the Powder River Basin (PRB) in Wyoming and Montana, because it has been the most productive coal basin in the United States over the past 25 years. The results of the PRB assessment were published in Professional Paper 1809 in 2015.
The Powder River Structural Basin covers an area of more than 61,000 km 2 in northern Wyoming and southern Montana (Fig. 1). The Basin is an important source of energy resources, containing the largest coal resources of any coal field in the contiguous United States (Glass, 1997) and substantial oil and natural gas resources.

The purposes of this paper are to: (1) test the presumptive microbial origin of gas in subbituminous coal in the Powder River Basin, which is a prolific coalbed gas producer (Fig. 1); (2) compare results of our work to previous investigations by Rice, 1993, Gorody, 1999; (3) expand the work on isotopic composition and fractionation of deuterium (D) between water and methane (CH 4) and of ...
Coal quality in Southern Wyoming can vary considerably; however, coal deposits are characterized by high BTU, low sulphur and low ash. Arch Resources. Eagle Specialty Materials. Navajo Transitional Energy Co . Peabody Energy. Southern Wyoming (the Green River/Hanna Basins) consists of multiple major coal fields.
The Illinois Basin and Northern Appalachian (NAPP) coals have lower ash fusion temperature and higher Fe and S content than Central Appalachian (CAPP) coal or Powder River Basin (PRB) coal. Table 1.
The Powder River Basin (PRB) of Wyoming and Montana is a major coalproducing region in the United States. It also has produced large quantities of natural gas and oil, and has experienced significant development of coal bed natural gas (CBNG) from its coal seams. The region has a
However, the Powder River Basin Resource Council is concerned. It has been fighting Ramaco for years, back when the company still planned to mine coal. Residents worried how its presence might ...
Over the years, the federal government has sold leases in the Powder River Basin for about per ton of coal or less. The market price of Powder River Basin coal is about a ton ...
Welcome Powder River Basin Resource Council is committed to empowerment of people through community organizing. More than ever, it is crucial that Wyoming's voice for responsible development, Powder River Basin Resource Council, be a part of the debate that will determine Wyoming's future. Get Involved

Coal. We help keep the lights on! BNSF is a critical component in coal delivery for electricity generation, industrial use and export. We offer efficient, reliable delivery through proven routes with broad access to western coal production. BNSF is a vital link to lowcost Powder River Basin (PRB) coal. Contacts.
The biggest coal deposit by volume is the Powder River Basin in Wyoming and Montana, which the USGS estimated to have trillion short tons of inplace coal resources, 162 billion short tons of recoverable coal resources, and 25 billion short tons of economic coal resources (also called reserves) in 2013. The coal in the Powder River Basin is subbituminous in rank.

By 2003, the Powder River Basin yielded more coal than the Appalachian coal basins in the eastern United States. Both total coal production and PRB coal production peaked in 2008 and have since declined.
Within a given basin, various structures tend to be associated with enhanced gas production. In the Powder River basin, folds with up to 75 m of structural relief were created by differential compaction. ... These insights are valuable for locating thicker and higherquality coal bodies, predicting whether these will be connected at a given ...
More than a million tons of publiclyowned federal coal leaves Wyoming's Powder River Basin each day, bound for power plants across the nation. It's a big part of the state's economy and the nation's energy mixbut it also takes a toll on our state.
During the production of CBM, water is pumped from wells, lowering hydrostatic pressure in the coal beds and allowing the previously confined methane that is stored within the internal surfaces and voids of the coal to flow (DeBruin and others, 2000). ... The effect of CBM discharge waters on streamwater quality in the Powder River Basin is ...
The Powder River Basin coalbed methane boom in the early 2000s stirred controversies over land rights, mineral rights, environmental stewardship, the disposal of water and—at every turn—politics. Now, few of the 29,000 wells drilled produce much gas and around 3,000 wells are abandoned and left to the state to clean up.
The Energy Information Administration estimates (as of October 2022) that in 2021, CO 2 emissions from burning coal for energy accounted for about 20% of total energyrelated CO 2 emissions and for nearly 60% of total CO 2 emissions from the electric power sector. In the past, fly ash was released into the air through the smokestack ...

In the Powder River Basin, for example, coal is of insufficient thermal maturity to have generated thermogenic hydrocarbons, and geochemical data indicate that all produced gas is effectively of biogenic origin [54], [55]. Methanogenesis occurs along two major metabolic pathways: methyltype fermentation and CO 2 reduction shown in Fig.
The Powder River Basin (PRB), located in the western United States, is a coal mining region that has evolved throughout the half century since the first largescale mine began in the 1970s, as shown in Fig. related to commodity pricing, high inflationary periods and, more recently, low demand, associated with power producers switching from coal to natural gas or renewable energy ...
Cretaceous The thickest section of the Powder River Basin is composed of Cretaceous rocks, an overall regressive sequence of mostly marine shales and sandstones deposited in the Western Interior Seaway Tertiary The coal beds of the region began to form about 60 million years ago when the land began rising from a shallow sea.
Factors that affect TRDU product gas quality appear to be coal type, temperature, and oxygen/fuel ratios. During this series of tests, a previously tested baseline Powder River Basin (PRB) subbituminous coal from the Peabody Energy North Antelope Rochelle Mine near Gillette, Wyoming was mixed with 20 wt% biomass. Two types of biomass were used ...
