Characteristics and control mechanism of nanoscale pores in lacustrine tight carbonates: Examples from the Jurassic Da'anzhai Member in the central Sichuan Basin, China
TL;DR: In this article, Li et al. quantitatively investigated the control mechanisms of nanoscale pores in Lacustrine Tight Carbonate (LCLC) reservoirs and found that the relatively small, 3-5-nm, interparticle and micro-cracks made a dominant contribution to the storage space.

Investigation of enhancing multi-gas transport ability of coalbed methane reservoir by oxidation treatment
TL;DR: In this article, the authors investigated the multi-gas transport ability enhancement of coalbed methane reservoir after oxidation and showed that the reaction between coals and oxidants accelerated methane desorption, widened the methane mass transfer channel, and finally enhanced the methane multi gas transport ability of coal in coal.

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.
