Impact of Inter‐Well Stress Interference on Multifracture Propagation in Tight Reservoirs
Energy Science &Engineering, Volume 14, Issue 1, Page 347-363, January 2026.This study presents a integrated computational‐experimental framework for modeling complex fracture propagation. Using a novel cell‐based fracture element approach with defined geometric and mechanical parameters, we simulate crack paths under varying stress conditions (e.g., SH‐Sh = 130 psi).

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.Concrete is the most widely used construction material globally, but it is inherently prone to various factors such as environmental conditions, mechanical stress, and chemical reactions. Stresses such as cracks can significantly reduce the lifespan of concrete structures, leading to increased maintenance costs and environmental impact.

Characterization of Proppant Flowback in Hydraulic Fracturing Rough Fractures
Energy Science & EngineeringIn the process of fracturing, proppant flowback is unavoidable, and excessive proppant flowback will cause sand plugging in the wellbore, change the morphology of proppant fractures, reduce the effective flow‐conducting capacity of fractures, weaken the ...

International 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.

Experimental study on the self-suspending proppant-laden flow in a single fracture
REM: International Engineering JournalThe 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.
