Abstract Earthquake source parameters are crucial for assessing seismic hazard and understanding earthquake source physics. However, source parameter estimation is challenging for small earthquakes because they suffer notorious trade‐offs with shallow attenuation.

Abstract Porosity and permeability in crystalline shield basement are commonly assumed to be low, yet some fault zones sustain fluid circulation over kilometer scales. Here we quantify multiscale fault‐zone connectivity at Kivetty, central Finland, by integrating legacy deep‐borehole data, including packer tests, downhole logs, and a long‐term multi ...

On the Leaky Nature of Fractures in Low‐Permeability Rock
Abstract Hydraulic‐test interpretation in fractured rock commonly assumes impermeable confining matrices, an assumption we show is systematically incorrect, even when the matrices are 7–14 orders of magnitude less permeable than the fracture. Fluid injected into a fracture begins to leak into the surrounding rock matrices within milliseconds to seconds,

Performance of Hybrid Single Well Enhanced Geothermal System and Solar Energy for Buildings Heating
The energy reserves in hot dry rock and hydrothermal systems are abundant in China, however, the developed resources are far below the potential estimates due to immature technology of enhanced geothermal system (EGS) and scattered resources of ...

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

Geothermal power generation potential in the United States by 2050
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 ...

Anisotropic Biot Coefficient of Fractured Rocks Drives Failure Conditions in Pressurized Reservoirs
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 ...
