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

Journal 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 ...

Geothermal power generation potential in the United States by 2050

Environmental Research: Energy
Geothermal energy provides a dispatchable source of carbon-free electricity that can balance the output of variable resources. However, geothermal provides just 3.7 gigawatts (GW _e ) ( ${\lt}$ 1%) of electricity in the United States today, mostly from ...

A Multiscale Approach to Simulate Non‐Isothermal Multiphase Flow in Deformable Porous Materials

Water Resources Research, Volume 61, Issue 12, December 2025.
Abstract Coupled thermal, hydraulic, and mechanical processes in porous materials play important roles in several energy and environmental technologies. The Darcy‐Brinkman‐Biot (DBB) framework has proven effective in modeling multiphase fluid flow in deformable porous solids across both pore and Darcy scales, including in systems where fractures ...

Thermo‐Hydro‐Mechanical Behavior of Saturated Porous Media Under Non‐Isothermal Flow With Fine Particle Migration

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 49, Issue 16, Page 3731-3752, November 2025.
ABSTRACT Clogging of reservoir formations, known as permeability damage, and wellbore clogging due to mobilization and straining of in situ fine particles are critical challenges in enhanced geothermal systems. This study presents a novel fully coupled thermo‐poro‐elastic model to predict the thermo‐hydro‐mechanical (THM) response of saturated porous ...

Extraction of geothermal fluids from enhanced geothermal systems: optimization of a gas lift sparger

Geothermal Energy
This study explores the application of a gas lift system for extracting geothermal fluids from enhanced geothermal systems (EGS) with reservoir temperatures exceeding $$400^{\circ }$$ 400 ∘ C ( $$752^{\circ }$$ 752 ∘ F) and depths up to 15 km (9.3 mi ...

Enhanced Geothermal Systems (EGS) R&D Program: US Geothermal Resources Review and Needs Assessment [PDF]

, 2000
The purpose of this report is to lay the groundwork for an emerging process to assess U.S. geothermal resources that might be suitable for development as Enhanced Geothermal Systems (EGS). Interviews of leading geothermists indicate that doing that will be intertwined with updating assessments of U.S. higher-quality hydrothermal resources and reviewing

Limits of Self‐Propping in Enhanced Geothermal Systems: New Experimental Insights From Shear, Tensile and Saw‐Cut Fractures in Odenwald Granodiorite

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 10, October 2025.
Abstract Enhanced Geothermal Systems (EGS) use engineered fracture networks as fluid pathways and heat exchangers in hot, low‐permeability rock. Unlike gel‐proppant hydraulic fracturing treatments, many EGS use hydraulic shear stimulation to increase fracture permeability by self‐propping displaced rough surfaces of hard‐rock fractures caused by ...

Balancing reservoir creation and seismic hazard in enhanced geothermal systems [PDF]

, 2017
Fracture shear-dilatancy is an essential process for enhancing the permeability of deep geothermal reservoirs, and is usually accompanied by the radiation of seismic waves. However, the hazard and risk perspective of induced seismicity research typically
