A Novel Gas Extraction Technique in Coal Seams Utilizing Hydraulic Fracturing‐Dissolution and Analysis of Non‐Uniform Propagation of Fracture

Energy Science &Engineering, EarlyView.
ABSTRACT Extracting gas from low‐permeability coal seams is essential for mine safety and efficiency. To address this challenge, a novel technique combining hydraulic fracturing and dissolution was proposed. The feasibility of this method was verified through simulations based on the distinct element method.

Assessing connectivity between an overlying aquifer and a coal seam gas resource using methane isotopes, dissolved organic carbon and tritium [PDF]

, 2015
Coal seam gas (CSG) production can have an impact on groundwater quality and quantity in adjacent or overlying aquifers. To assess this impact we need to determine the background groundwater chemistry and to map geological pathways of hydraulic ...

Discussion on the production mechanism of deep coalbed methane in the eastern margin of the Ordos Basin

Energy Exploration & Exploitation
This study builds upon the research progress in the theories of CBM desorption, diffusion, and seepage flow to explore the production mechanisms of deep coalbed methane (CBM) in the Daing-Jixian block, aiming to achieve scientific and reasonable control of gas wells. Theoretical analysis suggests that CBM adsorption belongs to liquid–solid interfacial

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 ...

Chemical enhanced oil recovery from shale‐rich tight carbonate reservoirs using 2‐butoxyethanol as a mutual solvent and diluted seawater

The Canadian Journal of Chemical Engineering, Volume 103, Issue 5, Page 2119-2135, May 2025.
This graphical abstract shows the experiments conducted, including interfacial tension, contact angle, oil swelling and production under imbibition, along with graphs presenting the results. Abstract Oil production from tight reservoirs due to their very low permeability and high capillary pressure requires complex operations and materials, so that ...
