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 ...

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 ...

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 ...

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 ...

Monitoring Fracture Hydromechanical Evolution in the Lab and Field Using Unsupervised Metric Learning

Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 3, September 2025.
Abstract Fractures evolve in time through thermal‐hydraulic‐mechanical‐chemical (THMC) processes that alter their long‐range hydraulic transport properties and modify subsurface behavior and activities. The location of subsurface fractures makes it necessary to use remote sensing techniques such as passive or active seismic monitoring for fracture ...

A review of hot sedimentary aquifer geothermal resources in Australia

New Zealand Journal of Geology and Geophysics, Volume 68, Issue 3, Page 378-398, September 2025.
ABSTRACT Numerous currently operating, past and potential future geothermal energy projects in Australia depend on heat from hot sedimentary aquifer (HSA) sources. The relevant aquifers cover a range of geographical and geological settings. Currently operating geothermal energy projects in Australia (excluding ground source heat pumps) predominantly ...
