TLDR
In this paper, a series of laboratory experiments were performed to firstly analyze the characteristics of the pore structure in low-rank coal (R o 1000nm), with a poor development of mesopores (100-1000nm).About:

Development of Unconventional Reservoirs
TL;DR: In this article, the authors compared the porosity and pore size distribution in two different shale formations, i.e., the clay-rich Permian Carynginia Formation in the Perth Basin, Western Australia, and the claypoor Monterey Formation in San Joaquin Basin, USA.

Influence of mechanical grinding on characterization of nanopores of tectonically deformed coal: a comparative study between coal chunks and crushed coal
TL;DR: In this paper, the influence of mechanical grinding on the pore structure of Tectonically deformed coal was investigated by contrastive analysis, and it was shown that mechanical grinding significantly shortened the distance between adsorbate molecules and micropores.

Study of the Microstructure of Coal at Different Temperatures and Quantitative Fractal Characterization
Yongliang Xu,Lankun Wang +1 more
TL;DR: In order to understand the influence of underground coal fires on coal fractures and pores, mercury intrusion porosimetry (MIP) and scanning electron microscopy (SEM) are combined to study the development of coal pore and fracture under high-temperature treatment and calculate the fractal dimension as mentioned in this paper .

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.
