Fault‐Controlled Permeability: A Key Parameter in Geothermal Electricity Production Assessment

Terra Nova, EarlyView.
ABSTRACT Geothermal energy is central to the global green energy transition, but its development has long focused on regions with positive thermal anomalies. Through a semi‐quantitative global‐scale review and spatial analysis of 361 geothermal sites, we show that 56.2% of global geothermal electricity production occurs in regions with thermal ...

Repurposing of hydrocarbon wells for Enhanced Geothermal System (EGS) development [PDF]

Geothermics
The Groß Schönebeck research platform represents a case study for the reuse of the abandoned hydrocarbon well E GrSk 3/90. A detailed description of well selection criteria, subsurface conditions, and well modification procedures is presented as a workflow for the repurposing of hydrocarbon well as an injection well for an EGS development.

A sustainable clean energy source for mitigating CO2 emissions: numerical simulation of Hamit granitoid, Central Anatolian Massif

Geomechanics and Geophysics for Geo-Energy and Geo-Resources
Türkiye relies on coal-fired power plants for approximately 18 GW of annual electricity generation, with significantly higher CO2 emissions compared to geothermal power plants.

Magnitudes and Rates of Strength‐Drawdown Modulate Injection‐Induced Seismicity

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Accurately forecasting injection‐induced seismicity remains a major challenge that is critically important for energy production and storage as controlling mechanisms are complex and remain opaque. We clarify key processes by following time‐histories of bespoke parameters anticipated to control strength reduction (drawdown) through ...

Volatile Conduits Beneath Vulcano Island (Italy) Revealed by High‐Resolution Nodal Local Earthquake Tomography During Volcanic Unrest

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Understanding shallow magmatic and hydrothermal systems at active volcanoes is essential for interpreting unrest and forecasting eruptions. We present the first high‐resolution three‐dimensional Vp $Vp$, Vs $Vs$, and Vp/Vs $Vp/Vs$ models of Vulcano Island, Aeolian Islands, Italy, derived from a dense nodal seismic network.

Simulator‐Based Bayesian Inference of Enhanced Geothermal Reservoir Properties

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 5, October 2026.
Abstract Inversions of dynamic multi‐scale multi‐physics subsurface system properties rely on the effective sampling of high‐dimensional parameter spaces and are thus notoriously difficult to perform. The associated models are defined by complex nonlinear relationships with potentially stochastic components, which lead to analytically intractable ...

Caving‐enhanced geothermal system overwhelms fracturing‐ and pipe‐enhanced geothermal system in heat extraction

Deep Underground Science and Engineering, Volume 5, Issue 3, Page 854-868, September 2026.
Our study reveals that caving‐enhanced geothermal systems (C‐EGS) with adequately fractured reservoirs achieve optimal heat extraction by minimizing preferential flow paths, while conventional fracturing (F‐EGS) and pipe‐based (P‐EGS) systems suffer accelerated thermal drawdown.
