Powder River Basin The Powder River Basin (PRB) of Wyoming and Montanta is the largest low sulfur coal source in the nation. Eight of the ten largest mines in the United States are located in the PRB.
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 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 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
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.
The estimate assumed that Powder River Basin coal generates 8,500 BTUs per pound, and that one million BTUs would produce pounds of CO2, consistent with Department of Energy figures. The final calculation was 199 million tons of CO2 per year in "direct" emissions from the coal exports.
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.

This Task 1D Report for the Powder River Basin (PRB) Coal Review describes the existing environmental conditions in the PRB study area, with the exception of air quality, water resources, ... (Stricker and Ellis 1999). Coal quality data from the WyodakAnderson coal indicate that the coal is subbituminous, generally low sulfur, and has low ...

In the western United States, coal beds have burned naturally in several geologic basins in the states of Wyoming, Montana, North Dakota, Colorado, Utah, New Mexico, and Arizona Sigsby, 1966, Hoffman, 1996. The most extensive burning has been in the Powder River basin (PRB) of northeast Wyoming and southeast Montana Rogers, 1918, Coates and ...
Coal in the Powder River Basin. The Powder River Basin in the Red Desert stretches for more than 14 million acres from the peaks of Wyoming's Bighorn Mountains to the Yellowstone River in eastern Montana. It provides premier habitat for elk, mule deer, pronghorn antelope, wild turkeys, and the threatened greater sagegrouse in places like Otter ...
The Powder River Basin contains one of the largest resources of lowsulfur, lowash, subbituminous coal in the world and is the single most important coal basin in the United States.
Powder River Basin is a major coalbearing geologic structure underlying southeast Montana and northeast Wyoming, accounting for more than 40% of the country's coal reserves. ... Core holes are drilled for coal quality and also provide structure information. They are rotary drilled through the overburden to a designated core depth just ...
The objective of this research is to develop a costeffective catalytic pyrolysis process for producing highquality oil and gas from coal with low CO 2 emission. Catalytic pyrolysis of the Powder River Basin coal using composite Na 2 CO 3FeCO 3 catalysts has been investigated in a fixed bed reactor between 500 and 800 °C under atmospheric pressure to evaluate effects of catalyst on quantity ...
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) is a region in southeast Montana and northeast Wyoming about 120 miles east to west and 200 miles north to south known for its coal deposits. It is the single largest source of coal mined in the United States and contains one of the largest deposits of coal in the world. Most of the active coal mining in the Powder River Basin actually takes place in drainages of ...
A coal mine in the Powder River Basin has received state recognition for its reclamation efforts. The Wyoming Department of Environmental Quality (DEQ) recognized the Coal Creek Mine with its 2022 Excellence in Mining Reclamation Award for coal. Coal Creek Mine is operated by Thunder Basin Coal Company south of Gillette.
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 ...
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 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 ...
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 amount drops even more drastically when the coal's quality is factored in and compared against current prices. When the USGS data was first compiled, in 2013, Powder River Basin coal was selling for a ton, resulting in about 23 billion tons being designated as economicallyrecoverable. ... Powder River Basin coal was selling for 10. ...
The Powder River Basin, or PRB, which is home to the largest coal reserves in the United States, currently supplies approximately 40 percent of the nation's coal and accounts for a full 13 ...
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.
Coal companies in the Powder River Basin in Montana and Wyoming can extract more than 10 times as much coal per employee hour as coal companies operating in the Appalachian Basin. (see Figure 1)
The most important distinction between this Powder River Basin coal assessment and other, prior assessments, was the inclusion of mining and economic analyses to develop an estimate of the portion of the total resource that is potentially recoverable, not just the original (inplace) resources. ...
