Adsorption/desorption characteristics for methane, nitrogen and carbon dioxide of coal samples from Southeast Qinshui Basin, China [PDF]

open access: yes, 2013
This paper presents an experimental and modelling study of the adsorption/desorption of pure gases CH4, CO and N and their binary and ternary mixtures on coal samples obtained from southeast Qinshui Basin, China. Results show that the adsorbed amounts of

Study on the Physical Properties of Deep Coalbed Methane Reservoirs

open access: yesInternational Journal of Natural Resources and Environmental Studies
China has abundant deep coalbed methane (CBM) resources. Exploration and development efforts this year have revealed that deep CBM reservoirs are characterized by large resource volumes, intact coal structures, high gas content, high gas saturation, and significant development potential.

Characterization of the permeability evolution of hard and soft rocks under hydro‐mechanical coupling conditions

open access: yesDeep Underground Science and Engineering, Volume 5, Issue 1, Page 220-232, March 2026.
The permeability variation of rocks during complete stress–strain processes was investigated. A mathematical model describing the influence of rock damage on permeability was constructed. The permeability–stress relationship between soft rock and hard rock was proposed.

Potential for CO2 sequestration and enhanced coalbed methane production in the Netherlands [PDF]

open access: yes, 2006
This study investigated the technical and economic feasibility of using CO2 for the enhanced production of coal bed methane (ECBM) in the Netherlands. This concept could lead to both CO2 storage by adsorbing CO2 in deep coal layers that are not suitable ...
