China is vigorously promoting the development of coalbed methane (CBM) resources
because CBM is cleaner than coal and a hazardous gas in coal mining. However, the CBM …

Coal fines can substantially influence coal seam gas reservoir permeability, thus impeding
the flow of gas in coal microstructure. The coal fines generation and migration are influenced …

Marcolithotypes play a significant role in coal seam porosity and fracture heterogeneity. The
optical microscopy, CO 2 and N 2 adsorption, and X-ray CT were used for reconstructing the …

Field observations have shown that the concentration of fines produced during the early two-
phase flow stage in coalbed methane (CBM) reservoirs is much higher than single-phase …

Hydraulic fracturing is the main stimulation technique that enables the economic production
of coalbed methane reservoirs. However, massive invasion and retention of coal fines in …

Methane extraction in deep coal seams is a multi-field coupling process affected by multiple
factors, and a systematic multi-field coupling theory is of guiding significance for ensuring …

In this study, based on compiled numerical-experimental datasets, important variables,
including porosity, density, compressional and shear wave velocity, were utilised to develop …

The sensitivity of coal reservoir is an essential reason decreasing the coalbed methane
(CBM) production during the CBM development. Whether the acid sensitivity is a negative or …

Hydraulic fracturing is an effective approach to improve the productivity of coalbed methane
(CBM) reservoirs. However, during hydraulic fracturing and CBM production, massive coal …

Undersaturated reservoirs, hydraulic fracturing, and permeability velocity-sensitive damage
are important factors of coalbed methane (CBM) development, but some scholars consider …
