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′

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 ...

Characterization of mechanical properties of shale constituent minerals using phase‐identified nanoindentation

Computer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 4, Page 542-558, 4 February 2025.
Abstract Characterization of mechanical properties of shale constituent minerals (viz., the mechanical genes of shale) has been challenging but of great significance for engineering applications in shale formations. In this study, a phase‐identified nanoindentation is proposed to decode the mechanical genes of shale using a large nanomechanical dataset.

Height Propagation Law and Controlling Strategies of Acid Fractures in Carbonate Gas Reservoirs With Bottom Water Layer Under Different Stress Profiles

Geofluids, Volume 2025, Issue 1, 2025.
Acid fracturing is currently employed to develop the carbonate gas reservoir in the second section of the Dengying Formation at the Anyue Gas Field, Sichuan Basin. However, improper acid‐fracturing operational parameters pose a risk of fracture communication with the bottom water layer, leading to increased water production and a significant decline in
