Thermo‐Hydrodynamic Processes of Microparticles in Fractures: A CFD–DEM Approach
International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 10, Page 4230-4246, July 2026.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 ...

Anisotropic Biot Coefficient of Fractured Rocks Drives Failure Conditions in Pressurized Reservoirs
Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.Abstract We present a theoretical framework to quantify the equivalent Biot coefficient tensor of fractured rock masses based on the properties of both the intact porous matrix and the fracture network. Our results show that the presence of dominant fracture sets produces an anisotropic equivalent Biot tensor, with larger values in the direction ...

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).

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.Abstract One promising potential site for extracting supercritical geothermal fluids is the Krafla volcano, Iceland, into which a borehole was drilled very close to a shallow rhyolite magma chamber at about 2 km depth. Besides the technical challenge to drill in this setting, the extreme temperature conditions of T > 900°C close to the magma body may ...

Development of Enhanced Geothermal Systems (EGS) in Northern Alberta
, 2015 In the province of Alberta a huge amount of energy is needed for diverse applications. Specifically, the demand for heat is limited to a few locations such as the oil sands operation regions and metropolitan areas. Oil sands processing facilities near Fort McMurray and direct heat provision for different applications in the City of Edmonton are two of ...

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