Pore characteristics and its heterogeneity of lignite reservoir in the Erlian Basin of Inner Mongolia, China
TL;DR: In this article , three sets of lignite reservoirs in the Jiergalangtu depression were taken as the research object, and the scanning electron microscope (SEM) images were converted from time-domain signals to frequency-domain signal through Fourier transformation, which quantitatively characterizes the heterogeneity of coal reservoirs.

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.

Petrophysical characterization of coals by low-field nuclear magnetic resonance (NMR)
TL;DR: Wang et al. as mentioned in this paper proposed a new NMR-based per-meability model that better estimates the permeability of coals, which has potential applications for NMR well logging in coalbed methane exploration.
