Performance Comparison of H2O and CO2 as the Working Fluid in Coupled Wellbore/Reservoir Systems for Geothermal Heat Extraction

Frontiers in Earth Science, 2022
CO2 is considered as a novel heat-transmission fluid for extracting geothermal energy from enhanced geothermal systems (EGS), attributed to its high compressibility, expansivity and low viscosity in comparison to water.

Thermo‐Hydrodynamic Processes of Microparticles in Fractures: A CFD–DEM Approach

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Controlling fracture permeability plays a critical role in subsurface energy applications, particularly in geothermal energy production and enhanced carbon sequestration, where regulating fluid flow is essential. The use of microcapsules has become a promising solution to enhance fracture permeability by providing a controlled sealing ...

Simulating the Impacts of Deep Geothermal Development on Shallow Hydrothermal Resources in a Rocky Mountain Rift Valley

Groundwater, EarlyView.
Abstract Numerical modeling has been widely used to assess the feasibility of geothermal energy development at sites across the world, but modeling applications simulating the potential impacts on shallow hydrothermal resources and surface water are relatively scarce. In this study, we apply the MODFLOW 6 groundwater energy (GWE) code to simulate fully

Temporal Change in Resistivity Structure Before and After the 2018 Small Phreatic Eruption Iwo‐Yama Volcano, Kirishima Volcanic Complex, Japan

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract A small phreatic eruption occurred on April 2018 Iwo‐yama, Kirishima volcanic complex, Japan. We estimated the change in the subsurface resistivity structure before and after the phreatic eruption by repeated magnetotelluric (MT) measurements. A substantial decrease in resistivity was determined in the zone from the surface down to a depth of ...

Influence of Temperature on Seismic Moment as a Diagnostic for Crustal Permeability Creation

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract Understanding what controls permeability is important in modulating crustal processes and the recovery of fuels and energy from the subsurface. Permeability may be created by the reactivation of fractures creating connected flow pathways that result in microearthquakes (MEQs).
