A comparison study of reservoir boundary conditions of Enhanced Geothermal Systems (EGS)

open access: yesEnergy Procedia, 2019
Abstract The effects of boundary conditions on numerical reservoir prediction of Enhanced Geothermal Systems (EGS) are crucial to EGS modeling while have drawn little attention in previous studies. Based on geothermal characteristics of Gonghe Basin, China, we established a thermal-hydraulic-mechanical coupled model to compare the performance of ...

Numerical Simulations of Hydraulic Fracturing in Carbonate‐Type Hot Dry Rock Reservoirs Based on the Coupled Thermo‐Hydraulic‐Mechanical‐Damage (THMD) Model

open access: yesEnergy Science &Engineering, Volume 13, Issue 12, Page 5821-5834, December 2025.
ABSTRACT Hydraulic fracturing technology is widely used in Enhanced Geothermal System (EGS) projects to induce fractures and enhance the permeability of thermal reservoirs. The hydraulic fracturing process of hot dry rock (HDR) is actually a multiphysics coupling process that couples the heat transfer field, seepage field, stress field, and damage ...

The Effect of Pressurization Rate and Pattern on Injection‐Induced Seismicity in Highly Permeable Sandstone: An Experimental Study

open access: yesJournal of Geophysical Research: Solid Earth, Volume 130, Issue 12, December 2025.
Abstract Effectively mitigating induced seismicity in subsurface engineering operations within highly permeable, porous geo‐energy reservoirs requires a clear understanding of how fluid injection parameters influence the seismic response. In this study, we performed injection‐driven fault reactivation experiments on highly permeable saw‐cut Red Felser ...

Fluid Pressure Diffusion and Elastic Stress Transfer From Seismic Slip Control Slip Front Expansion in Fluid‐Driven Swarm Seismicity

open access: yesJournal of Geophysical Research: Solid Earth, Volume 130, Issue 12, December 2025.
Abstract Observations of fluid‐driven swarm seismicity expanding with the same diffusive space‐time behavior as analytical solutions for aseismic slip have been interpreted as evidence that stress changes from aseismic slip trigger seismic slip. In some cases, aseismic slip is confirmed from crustal deformation measurements or sheared wellbore casing ...
