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

Image-based Stokes flow modeling in bulk proppant packs and propped fractures under high loading stresses

, 2015
Rock fracturing, followed by proppant injection, has been used for years to improve oil and gas production rates in low permeability reservoirs and is now a routine part of producing from low-permeability resources such as a shales and tight sands. While

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.

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′

Proppant embedment behavior and elastic–plastic embedding depth modeling of coal reservoirs under multi-stage loading

Meitan xuebao
To investigate the elasto-plastic embedment behavior of proppant during coalbed methane (CBM) production, a mechanical testing system equipped with a high-precision displacement sensor was used to design and conduct proppant-embedment tests under multi ...

From Empirical Models to Physics‐Informed Neural Networks: The Evolution of Oil Production Forecasting

Journal of GeoEnergy, Volume 2026, Issue 1, 2026.
Production forecasting for oil and gas wells is a decisive element of field‐development planning because it directly guides recovery strategy design, production optimisation and risk management. Conventional methods, including empirical decline‐curve analysis (DCA) and full‐physics numerical simulation, are limited either by their inability to capture ...

Proppant Shape Effect on Dynamic Conductivity of a Fracture Filled with Proppant

, 2018
Many studies showed that the particle shape has a significant effect on mechanical properties of sands. We are investigating the effect of proppant angularity on the dynamic conductivity of a fracture filled with proppant by simulating the irregularly ...

Long‐term fracture conductivity in tight reservoirs

Energy Science & Engineering
Reservoir stimulation using hydraulic fracturing technology is one of the most common stimulation measures to develop tight oil and gas reservoirs, and the conductivity of fractures after fracturing is the key to the stimulation effect of oil fields.
