2003.10.5 Abstract. Just over ten years ago, coal bed methane production from Wyoming's Powder River Basin was virtually non-existent. Today, total gas production from Powder River Basin coals is almost 1 Bcf per day from nearly 10,000 wells. This tremendous resource is unique compared to other commercial coalbed methane plays with gas

2022.8.1 1. Introduction. While traditional uses of coal (i.e. combustion) are associated with the release of CO 2 emissions into the atmosphere, coal gasification could be considered a sustainable coal utilization strategy for low-cost, low emissions production of syngas (H 2 + CO). Recent developments in carbon management technologies, such

2013.8.1 In contrast, the subbituminous coal samples come from a coal seam in the Powder River Basin with substantial CBNG production. The CBNG produced from the Wyodak-Anderson coal zone throughout the Powder River Basin is known to be primarily biogenic in origin as evidenced by isotopic fractionation (δ 13 C and δD) analysis of gas

2016.3.1 However, for Wyodak coal only CO 2 was higher with gaseous O 2. Since Wyodak coal, a sub-bituminous coal, produces substantial amount of synthesis gas during steam gasification, some of the CO may have reacted to form CO 2, and H 2 may have reacted to form H 2 O with gaseous O 2. 3.6.

Coal has been mined exclusively from the Wyodak-Anderson (WA) Seam. The remaining coal is 50-87 ft thick and 180 to 460 ft deep within the leased area. The WA seam is in the uppermost section of the Paleocene Fort Union Formation. The coal is thickest on the northwest side of the lease. There are two main geologic features at NARM.

The Wyodak coal zone, including the Lower and Upper Wyodak and Wyodak Rider zones, contains the Canyon, Anderson, Smith, and Big George coals, which are CBM production targets. Vertical and lateral correlations in the Fort Union Formation show successive splitting of thick coal beds resulting in overlapping coal zones (Flores et al., 2010).
