Effect of Fluid Contact Angle of Oil-Wet Fracture Proppant on the Competing Water/Oil Flow in Sandstone-Proppant Systems

, 2022
Ceramic fracture proppants are extensively used for enhancing the recovery of fossil energy and geothermal energy. Previous work has reported the attracting-oil-repelling-water (AORW) property of oil-wet proppants at the faces of fractures.

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).

Influences of Proppant Concentration and Fracturing Fluids on Proppant-Embedment Behavior for Inhomogeneous Rock Medium: An Experimental and Numerical Study

, 2018
Summary Proppant plays a vital role in hydraulic fracturing in tight oil/gas production because it helps to keep the fractures open during the production process.

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.

Evaluating the stability and volumetric flowback rate of proppant packs in hydraulic fractures using the lattice Boltzmann-discrete element coupling method

Journal of Rock Mechanics and Geotechnical Engineering
The stability and mobility of proppant packs in hydraulic fractures during hydrocarbon production are numerically investigated by the lattice Boltzmann-discrete element coupling method (LB-DEM). This study starts with a preliminary proppant settling test,

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

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.

Numerical Modeling of Proppant Transport in Complex Hydraulic Fracture Propagation

, 2017
Hydraulic fracturing is a stimulation technique used in unconventional reservoirs to generate sufficient reservoir contact for viable production. During stimulation, proppant is pumped into the system to keep fractures open when, at a later stage ...
