Mitigating Surface Tension Effects in Multi‐Coalbed Methane Reservoirs: Case Study of Liupanshui Field

open access: yesInternational Journal of Energy Research, Volume 2026, Issue 1, 2026.
Water locking effect caused by surface tension severely restricts coalbed methane (CBM) productivity in multilayer reservoirs. The Songhe demonstration area features main target coal seams with overpressure, high gas content, and high gas saturation, presenting favorable CBM development conditions.

Study on Proppant Transport and Placement in Shale Gas Main Fractures

open access: yesEnergies
In this paper, based on the background of a deep shale reservoir, a solid–liquid two-phase flow model suitable for proppant and fracturing fluid flow was established based on the Euler method, and a large-scale fracture model was established.

Experimental Study on Multiscale Evolution Mechanism of Coalbed Reservoir Properties in “Three‐Low” CBM Reservoirs Modified by Chlorine Dioxide

open access: yesGeofluids, Volume 2026, Issue 1, 2026.
Aiming at the “three‐low” challenges (low permeability, low gas saturation, and low critical desorption‐to‐storage ratio [CDSR]) of Chinese coalbed methane (CBM) reservoir materials, this study adopted chlorine dioxide (ClO2) chemical modification on long‐flame, coking, and anthracite coal materials.

Hydraulic‐Mechanical Coupling‐Driven In Situ Stress Field Evolution in Injection‐Production Well Patterns With Artificial Fractures

open access: yesGeofluids, Volume 2026, Issue 1, 2026.
Based on the theory of porous media elasticity and the mechanisms of hydraulic‐mechanical coupling, a fully coupled mathematical model for porous media deformation and fluid flow was established, incorporating a square inverted nine‐spot well pattern with artificial fractures. The finite element method was employed for numerical solution, and the model′
