Spatial Variations in Methane Content and Their Main Controlling Factors of the Deep‐Buried Coalbed in the Nalinhe–Hengshan Area, Ordos Basin

Energy Science &Engineering, Volume 14, Issue 7, Page 3422-3433, July 2026.
Ash yield is the primary geological factor controlling the spatial variations in the total gas content of the deep‐buried coalbed methane in the Nalinhe‐Hengshan area, Ordos Basin. However, porosity dominates the differential enrichment of the free gas content of the deep‐buried coalbed methane in the Nalinhe‐Hengshan area, Ordos Basin.

Feasibility Analysis and Optimal Design of Acidizing of Coalbed Methane Wells [PDF]

Journal of Energy Resources Technology, 2019
Plugging is a prominent reason for production reduction in coalbed methane (CBM) wells. In order to solve this problem, authors conducted the feasibility analysis and optimal design of acidizing of CBM wells to remove the plugging in Hancheng block (H block) China. First, X-ray diffraction analysis shows that the plugging contains acid-soluble minerals

Study on Deformation Law of Crossing Layer Drilling Superimposed Floor Roadway

Energy Science &Engineering, Volume 14, Issue 6, Page 2752-2771, June 2026.
Based on deformation law of crossing layer drilling superimposed floor roadway, low dip angle drilling is particularly susceptible to complications such as borehole blockage and collapse. ABSTRACT Floor extraction roadway crossing layer drilling is a pivotal strategy for gas control in areas prone to coal and gas outbursts.

Numerical well test for well with finite conductivity vertical fracture in coalbed

, 2014
A new well test model is developed for the hydraulic fractured well in coalbed by considering the following aspects: methane desorption phenomena, finite conductivity vertical fractures, and asymmetry of the fracture about the well.

Parametric and predictive analysis of horizontal well configurations for coalbed methane reservoirs in Appalachian Basin [PDF]

, 2004
It has been a well-established fact that the Appalachian Basin represents a high potential region for the Coalbed Methane (CBM) production. The thin coal beds in the Appalachian basin are characterized by low porosity and permeability values.

Experimental Investigation of Sensitivity for Coal and Gas Outburst Risk Prediction Indexes in Raw and Tectonic Composite Coal Seams

Energy Science &Engineering, Volume 14, Issue 6, Page 2772-2784, June 2026.
A comparative study was conducted on gas desorption laws of raw and tectonic coals. The sensitivity of regional and local outburst prediction indexes was compared. Gas content is more sensitive than gas pressure for composite coal seams. K1 can more accurately predict the outburst danger than Δ h 2 in composite coal seams.

Appraising Carbon Geological‐Storage Potential in Saline Aquifers Using Two‐Phase Rate‐Transient Analysis

Water Resources Research, Volume 62, Issue 4, April 2026.
Abstract Rate transient analysis (RTA) is a practical and cost‐effective method for CO2 injection data analysis and storage capacity evaluation of saline aquifers. However, the nonlinear behavior introduced by two‐phase CO2–brine flow, coupled with pressure‐dependent fluid and rock properties, significantly limits the applicability of conventional ...
