INFLUENCE OF VERTICAL DEVIATORIC STRESS ON PERMEABILITY CHANGES IN COAL [PDF]
, 2014 Coalbed methane is becoming become an important component of the world\u27s natural gas resource. To date, researchers have mostly investigated the permeability changes due to non-linear elastic deformation caused by a matrix shrinkage associated with ...

Calculation model for water influx and controlled reserves for CBM wells with high water yield
Petroleum Research, 2018 Compared with conventional gas reservoir, percolation mechanism of coalbed methane (CBM) is completely different, it is remarkably affected by adsorption/desorption performance, pressure variation and coalbed characteristics.

Experimental Study on Methane Desorption from Lumpy Coal under the Action of Hydraulic and Thermal
Advances in Materials Science and Engineering, 2018 Moisture and thermal are the key factors for influencing methane desorption during CBM exploitation. Using high-pressure water injection technology into coalbed, new fractures and pathways are formed to transport methane. A phenomenon of water-inhibiting

Journal of Geophysics and Engineering, 2014 Proximate analysis components, gas content, porosity and permeability are the most important parameters for CBM reservoir evaluation. Based on the analysis of the conventional well log response of the no. 3 and no. 15 CBM seams in the southern Qinshui basin of China, regression analysis is used to establish the prediction models of the components of ...
