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

open access: yesEnergy 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.

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

open access: yesEnergy 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

Experimental study on the self-suspending proppant-laden flow in a single fracture

open access: yesREM: International Engineering Journal
The flow of proppant-laden fluid (PLF) in the fracture is a typical problem of solid-liquid two phase flow, and the transportation and deposition of proppants are essential to determine the flow conductivity of hydraulic fracturing.

Numerical Modeling of the Recession and Closure of Planar Hydraulic Fractures: Contact‐Based Versus Asymptotic‐Informed Schemes

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, Volume 49, Issue 17, Page 4054-4075, 10 December 2025.
ABSTRACT We compare two algorithms to simulate the propagation, arrest, recession, and closure of a planar hydraulic fracture, focusing on their ability to capture the physical processes governing fracture recession and closure. The first algorithm is based on a fixed grid with contact detection during recession, while the second is based on a moving ...
