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).

Study on Proppant Transport and Placement in Shale Gas Main Fractures

Energies
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 Influence of Sporosarcina ureae Bacteria on Mechanical and Fresh Properties of Self‐Healing Concrete With Focus on Elemental/Microstructural Analysis

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.
