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.

Uncertainty Analysis of Coalbed Methane Economic Assessment with Montecarlo Method [PDF]
, 2012 Uncertainty analysis of coalbed methane (CBM) economic assessment is key to weakening the high potential risks of CBM exploration. In this paper, the uncertainty analysis method of CBM projects is created with montecarlo simulation.

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

Coalbed Methane. 2015 - 2019 Bibliometric Analysis
, 2019 Motivations: It is estimated that the forecasted methane resources of Russia's main coal basins contain 83.7 trillion cubic meters, representing roughly one-third of the country's natural gas reserves, but the production of CBM is rather small.

The composition of coalbed gas [PDF]
"Samples of gas were obtained directly from the coalbed during drilling of horizontal and vertical boreholes in six different formations. The samples were analyzed by gas chromatography for C1 to C5 hydrocarbons and for 02, N2, H2, He, and CO2.
