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

Geofluids, 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.

The influence of fracturing fluid temperature and viscosity on the migration and distribution of proppants within a fracture

Journal of Petroleum Exploration and Production Technology
This work presents a numerical study incorporating the impact of temperature variations along the fracture on the viscosity of fracturing fluids and consequently on proppant distribution in hydraulic fracturing. Traditional models have not considered non-

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

Geofluids, 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′

An Approach to Sustainable Hydrogen Generation From Stimulated Iron‐Rich Ultramafic Rock

Geophysical Research Letters, Volume 52, Issue 24, 28 December 2025.
Abstract Iron‐rich rocks undergoing oxidation in the presence of water are promising sources of geologic hydrogen (H2). Yet, such reactions are often considered self‐limiting due to passivation and reduced permeability if volume expansion occurs. This study investigates hydrogen generation during a flow‐through experiment on fractured iron‐rich cores ...

UFM‐Based Simulation of Competitive Multi‐Fracture Propagation in Horizontal Wells

Energy Science &Engineering, Volume 13, Issue 12, Page 6069-6083, December 2025.
Simulation schematic of Competitive Multi‐Fracture Propagation in Horizontal Wells. ABSTRACT Multi‐stage hydraulic fracturing in horizontal wells is vital for stimulating unconventional reservoirs, yet uneven fracture propagation often restricts the effective communication volume of the reservoir.

Evolution of Friction and Permeability in a Propped Fracture under Shear

Geofluids, 2017
We explore the evolution of friction and permeability of a propped fracture under shear. We examine the effects of normal stress, proppant thickness, proppant size, and fracture wall texture on the frictional and transport response of proppant packs ...

A Prior Assessment of Heat Transfer Efficiency From Shale Formations to Hydraulic Fractures in Geothermal Wells Converted From End‐of‐Lifetime Natural Gas Wells

Energy Science &Engineering, Volume 13, Issue 12, Page 5802-5809, December 2025.
ABSTRACT Although the conversion of end‐of‐lifetime fractured hydrocarbon wells to geothermal wells has gained a strong momentum in research, it is necessary to perform thorough technical assessments of well conversion before pilot testing. The objective of the study was to perform such an assessment on converting fractured horizontal hydrocarbon wells

Characterization of Proppant Flowback in Hydraulic Fracturing Rough Fractures

Energy Science &Engineering, Volume 13, Issue 11, Page 5768-5776, November 2025.
This graphical abstract reveals the proppant flowback mechanism and controlling factors in rough fracture through CFD‐DEM modeling. This study investigates unavoidable proppant flowback during fracturing, which leads to wellbore sand plugging and reduced fracture conductivity. A coupled CFD‐DEM model simulates flowback in rough fracture, revealing that
