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 ...

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.

Equivalent Modeling and Simulation of Fracture Propagation in Deep Coalbed Methane

Energies
Deep coalbed methane (CBM) is challenging to develop due to considerable burial depth, high ground stress, and complex geological structures. However, modeling deep CBM in complex formations and setting reasonable simulation parameters to obtain reasonable results still needs exploration.

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.

Research on the Multiscale Microscopic Pore Structure of a Coalbed Methane Reservoir

Energies
Coal rock pores are the space in which coalbed gas is stored and flows. Accurately characterizing the pore structure of coalbed gas is the foundation of coalbed gas reserve assessment and production forecasting.
