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

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

During the exploration and development of deep coalbed methane (CBM), delineating the thickness of coal seam and lithofacies of the roof and floor is one of the major challenging tasks. In past attempts, the prediction methods of these parameters have been limited to the conventional inversion.

A new phenomenon of pulsation of steam permeability is discovered. The permeability of high‐temperature steam in coal shows a periodic pulsation pattern with an increase in the injection time. A two‐phase flow theory of gas–liquid is adopted to elucidate the mechanism of pulsating seepage of steam.

CONSTRAINING THE MEAN RESIDENCE TIME AND FLOWPATH OF GROUNDWATER THROUGH COAL SEAMS USING NOBLE GASES [PDF]
Noble gases, specifically 4He concentrations, can be a useful tool for determining the rates of groundwater recharge, subsurface residence times, and groundwater flowpaths, especially in difficult to model complex formations such as fractured aquifers ...
