A fully coupled hydro-mechanical model for the modeling of coalbed methane recovery [PDF]

, 2017
Most coal seams hold important quantities of methane which is recognized as a valuable energy resource. Coal reservoir is considered not conventional because methane is held adsorbed on the coal surface. Coal is naturally fractured, it is a dual-porosity

Methodologies for Gas Content Evaluation in Deep Coal/Shale Formations: Assessment, Improvement, and Comparison

Journal of GeoEnergy, Volume 2026, Issue 1, 2026.
Gas‐in‐place (GIP) content is a critical indicator for evaluating deep coal/shale resource potential, typically categorized into lost gas content, desorbed gas content, and residual gas content. The lost gas content cannot be directly quantified and requires specific methods for assessment.

Quantitative Identification and Distribution Pattern of Macrolithotype of Coal in Deep Coal Seams of the Daji Block

Energy Science &Engineering, Volume 13, Issue 10, Page 4839-4852, October 2025.
ABSTRACT The construction of a logging response model for macrolithotypes in coal has been successfully completed. This model has enabled delineation of vertical and planar distribution patterns of coal macrolithotypes within the #5 and #8 coal seams of the Daji block, as well as to forecast the distribution of favorable reservoir conditions.

In situ loading of a pore network model for quantitative characterization and visualization of gas seepage in coal rocks

Deep Underground Science and Engineering, Volume 4, Issue 3, Page 437-451, September 2025.
Fine modeling of a three‐dimensional fracture structure under dynamic loading of coal is carried out. The streamline distribution law of pressure and velocity field in the loading process of the coal specimen is analyzed, the absolute permeability of the coal specimen is calculated, and the feasibility of the pore network model algorithm and finite ...
