“…The USGS test well was located approximately 20 km (12.4 miles) southwest and down dip from a productive well location in southeastern Uvalde County (Kincaid, E. D., number 10A). However, desorption analysis of samples from the USGS test well produced little if any gas (24). The coal sample TX was collected at the drill site as soon as the core reached the surface.…”

“…Although the lack of significant gas in place could be attributed to site characteristics (e.g., coal bed permeability or the lack of an underlying source of thermogenic gas), factors affecting biogenic gas generation were also considered (coal carbon bioavailability, environmental conditions limiting microbial growth, or absence of a capable microbial population). Initial studies indicated that an undefined fraction of negligible mass (0.25%) of the total carbon in the Texas coal sample (designated TX) was bioavailable (24).…”

Biogenic formation of methane from coal is of great interest as an underexploited source of clean energy. The goal of some coal bed producers is to extend coal bed methane productivity and to utilize hydrocarbon wastes such as coal slurry to generate new methane. However, the process and factors controlling the process, and thus ways to stimulate it, are poorly understood. Subbituminous coal from a nonproductive well in south Texas was stimulated to produce methane in microcosms when the native population was supplemented with nutrients (biostimulation) or when nutrients and a consortium of bacteria and methanogens enriched from wetland sediment were added (bioaugmentation). The native population enriched by nutrient addition included Pseudomonas spp., Veillonellaceae, and Methanosarcina barkeri. The bioaugmented microcosm generated methane more rapidly and to a higher concentration than the biostimulated microcosm. Dissolved organics, including long-chain fatty acids, single-ring aromatics, and long-chain alkanes accumulated in the first 39 days of the bioaugmented microcosm and were then degraded, accompanied by generation of methane. The bioaugmented microcosm was dominated by Geobacter sp., and most of the methane generation was associated with growth of Methanosaeta concilii. The ability of the bioaugmentation culture to produce methane from coal intermediates was confirmed in incubations of culture with representative organic compounds. This study indicates that methane production could be stimulated at the nonproductive field site and that low microbial biomass may be limiting in situ methane generation. In addition, the microcosm study suggests that the pathway for generating methane from coal involves complex microbial partnerships.

“…Coal surface area is related to cleat development, which is a function of coal rank, type, ash content and geometry (Laubach et al, 1998 The microbial ecology of coal seams is also a function of coal rank, type, ash content and geometry. Although secondary microbial methanogenesis is possible in coals of any rank (Rice, 1993;Scott, 1999;Strąpoć et al, 2011), coal bioreactor studies invariably use lignites and subbituminous coals, due to the observed decrease in microbial activity with decreasing coal oxygen content (Jones et al, 2008;Scott, 1999;Strąpoć et al, 2011). Moreover, laboratory studies have demonstrated specificity between indigenous microbial consortia and coal type in some settings (e.g.…”

“…It is the predominant gas in such reservoirs as the Illinois Basin (Strapoć et al, 2007) and the Powder River Basin . Studies both in the laboratory (Green et al, 2008;Harris et al, 2008;Jones et al, 2008) and in situ (Pfeiffer et al, 2010) showed that the microbes inhabiting coal beds were essential for the regeneration of biogenic CBM. Therefore, it is essential to survey the microbial communities associated with CBM to better understand the formation of existing CBM and the future potential of biogenic CBM regeneration.…”

a b s t r a c t a r t i c l e i n f oIt is generally believed that biogenic coal bed methane (CBM) is an end product of coal biodegradation by methanogenic archaea and syntrophic bacteria. In this work, the archaeal and bacterial communities of CBM reservoir associated with Ordos Basin in China were investigated using 454 pyrosequencing. Sampling produced water, coal and rock in the reservoir, a total of 46,598 sequence reads were obtained. All archaea were methanogens with the genus Methanolobus predominating. The genus consisted of 81.18% of pyrosequencing reads in water sample and > 99% in coal and rock samples. Although the phylum Proteobacteria was the main component of all samples, bacterial communities in coal and rock samples were similar at the genus level, which were distinctly separated with water sample. The results strongly suggested that methylotrophic methanogenesis governed the biogenic CBM formation. The separation of microbial communities between water and coal, rock samples should be considered when investigating the process of coal biodegradation and the generation of new biogenic CBM.
