The Powder River Coal Region of northeastern Wyoming and southwestern Montana contains North America's thickest and most extensive low-sulfur coal seams, including the seventy-foot-thick Wyodak seam, and the region's 269 million–ton production accounts for 70 percent of Plains production and 23 percent of combined U.S.-Canadian production.
2005年11月27日 There are “no-coal zones” within the Wyodak coal seam where the coal has been replaced by sandstones and shales. The “no-coal zones” are distributary fluvial channels that meandered throughout the swamps. Several methods have been developed to predict the locations of the fluvial channels and avoid drilling “no-coal zones.”
2015年11月1日 We developed a multicomponent, 1D advective transport model that describes the downgradient evolution of solute concentrations, 87 Sr/ 86 Sr ratios, and δ 11 B values in the Wyodak-Anderson Coal Bed (WACB) aquifer located in the Powder River Basin, Wyoming, USA. The purpose of the study was to evaluate the chemical
After three transfers, inoculum 3 produced over 0.04 mmol methane from Wyodak coal at pH 5 while the control produced no methane. Similarly, at pH 5, ]noculum 5 produced over 0.02 mmol methane from both Pittsburgh and Wyodak coals. In a few cases control tubes without coal produced methane, this requires additional study.
