Coalbed methane: A review
TL;DR: In this paper, it is shown that the micropores are where most methane adsorption occurs in coal seams, and the methane molecule may actually stretch, minutely, the pore and thus with de-gassing of the reservoir, could result in matrix shrinkage, allowing opening of the fracture (cleat) system in the coal and thus enhancing permeability.

Geological controls on prediction of coalbed methane of No. 3 coal seam in Southern Qinshui Basin, North China
TL;DR: In this article, coalbed methane (CBM) in Southern Qinshui basin (SQB), North China, was analyzed using coal petrology analysis, proximate analysis and methane adsorption/desorption, and the results showed that the coals from the SQB contain 0.59-3.49% moisture, 3.5-15.54% ash yield, 73.92% fixed carbon and 2.4-81.4% inertinite.

Recent developments in coal mine methane extraction and utilization in China: A review
TL;DR: Wang et al. as discussed by the authors presented a comprehensive review of how coal mine methane extraction and utilization evolve with time from underground extraction to surface drainage to combined surface-underground approach.
Journal ArticleDOI
Effect of organic type and moisture on CO2/CH4 competitive adsorption in kerogen with implications for CO2 sequestration and enhanced CH4 recovery
TL;DR: In this article, the competitive adsorption behaviors of CH4 and CO2 on dry and moist realistic kerogen models of different organic types by performing combined molecular dynamics (MD) and grand canonical Monte Carlo (GCMC) simulations were investigated.
Journal ArticleDOI
Molecular concept and experimental evidence of competitive adsorption of H2O, CO2 and CH4 on organic material
TL;DR: In this paper, the authors developed a molecular concept with experimental and literature support for sorption of CH 4, CO 2 and H 2 O on organic material over a broad range of thermal maturity (0.5 − 3.3% vitrinite reflectance).

Characteristics and origins of coal cleat: A review
TL;DR: Cleats are natural opening-mode fractures in coal beds and account for most of the permeability and much of the porosity of coalbed gas reservoirs and can have a significant effect on the success of engineering procedures such as cavity stimulations as discussed by the authors.

Coalbed methane sorption related to coal composition
TL;DR: In this article, the role of coal type (sensu maceral composition) is not fully established but it is clear that coal type may affect both adsorption capacity and desorption rate.
