Multi-phase coalbed methane content model in deep strata of eastern margin of Ordos Basin

Meitan kexue jishu
The deep coalbed methane resources in the Ordos Basin are abundant. Accurately understanding the laws and underlying mechanisms of coalbed methane content phase change is of great significance for achieving large-scale and efficient development of deep ...

Study on the Physical Properties of Deep Coalbed Methane Reservoirs

International Journal of Natural Resources and Environmental Studies
China has abundant deep coalbed methane (CBM) resources. Exploration and development efforts this year have revealed that deep CBM reservoirs are characterized by large resource volumes, intact coal structures, high gas content, high gas saturation, and significant development potential.

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 ...

Gas-bearing evaluation of deep coal rock in the Yan’an gas field of the Ordos Basin

Frontiers in Earth Science
The Yan’an gas field in the Ordos Basin is a typical deep coalbed methane field with tremendous resource potential. Evaluation methods for gas content in deep coal seams are urgently required to be established.

Reservoir reconstruction technologies for coalbed methane recovery in deep and multiple seams

International Journal of Mining Science and Technology, 2017
Multiple coal seams widely develop in the deep Chinese coal-bearing strata. Ground in situ stress and coal seam gas pressure increase continuously with the increase of the mining depth, and coal and gas outburst disasters become increasingly severe.

Anisotropic rock physics modeling and its application for deep coalbed methane reservoirs

Meitan xuebao
Rock physics modelling, as an important method to quantitatively characterize the properties of oil and gas reservoirs, is seldom applied to coalbed methane reservoirs, and most of the established rock physics models are targeted at shallow and medium ...

Characterization of the permeability evolution of hard and soft rocks under hydro‐mechanical coupling conditions

Deep Underground Science and Engineering, Volume 5, Issue 1, Page 220-232, March 2026.
The permeability variation of rocks during complete stress–strain processes was investigated. A mathematical model describing the influence of rock damage on permeability was constructed. The permeability–stress relationship between soft rock and hard rock was proposed.
