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.

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.

Stimulated Volume Determination of a Horizontal Well in a Shale Oil Reservoir in the Vaca Muerta Formation and Its Interaction With Existing Fracture Networks

Advances in Materials Science and Engineering, Volume 2026, Issue 1, 2026.
Hydraulic fracturing is a stimulation technique that plays a critical role to provide transport path networks in unconventional shale reservoirs, yet the quantitative characterization of fracture propagation, its interaction with natural discontinuities, and the resulting stimulated volume remain challenging in heterogeneous formations such as the Vaca

Proppant transport in dynamically propagating hydraulic fractures using CFD-XFEM approach. [PDF]

, 2020
Numerically modelling the fluid flow with proppant transport and fracture propagation together are one of the significant technical challenges in hydraulic fracturing of unconventional hydrocarbon reservoirs. The existing models either model the proppant

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

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 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′
