Study on the diffusion and migration law of CO2 sequestrated in abandoned coal mine goaf

Deep Underground Science and Engineering, EarlyView.
The goaf of an abandoned coal mine, endowed with expansive fracture spaces and an abundance of residual coal, can be capable of sequestrating substantial quantities of CO2. The residual coal is the principal medium for the sequestration of CO2 in the form of adsorption and the amount of sequestration is considerable.

Coalbed Methane Industry Development Framework and Its Limiting Factors in China

Geofluids, 2022
The current average daily gas production of single coalbed methane (CBM) wells in China is less than 1,300 m3. The low production rate of CBM wells dramatically limits the sustainable development of the CBM industry in China.

Experimental Study on Prevention of Coal and Gas Outburst by Hydraulic Fracturing in High Gas Coal Mine in Yangquan Mining Area

Energy Science &Engineering, EarlyView.
ABSTRACT To investigate the hydraulic fracturing mechanism of high‐fluid wells in the Yangquan mining area, coal seams from the Xinyuan and Xinjing mines were selected as research subjects. Experiments were conducted using the TCQT‐III low‐permeability coalbed gas‐phase displacement and production enhancement apparatus, along with the FINESORB‐3120 ...

Quantitative Prediction of Coalbed Gas Content Based on Seismic Multiple-Attribute Analyses [PDF]

, 2015
Accurate prediction of gas planar distribution is crucial to selection and development of new CBM exploration areas. Based on seismic attributes, well logging and testing data we found that seismic absorption attenuation, after eliminating the effects of

Research on IDS Water Injection for Prevention of Dynamic Disasters in High‐Stress Low‐Adsorption Coal Seams

Energy Science &Engineering, EarlyView.
ABSTRACT The deep coal seams in the Pingdingshan mining area are characterized by high stress and low adsorption capacity. Existing water injection additives have proven ineffective in preventing dynamic disasters. Research has found that IDS (iminodisuccinic acid tetrasodium salt) can dissolve minerals in coal, significantly improving the ...

Similar constructive method for solving the model of coalbed methane flow through coalbed methane reservoirs [PDF]

Journal of Geophysics and Engineering, 2018
Coalbed methane (CBM) is produced through desorption, diffusion, and seepage processes. However, pressure during CBM production, especially the seepage process, is a very complicated problem. Methods for solving the pressure models for CBM reservoirs are multidisciplinary and rather sophisticated.
