Analysis of microseismicity framing ML > 2.5 earthquakes at The Geysers geothermal field, California [PDF]

, 2019
Preparatory mechanisms accompanying or leading to nucleation of larger earthquakes have been observed at both laboratory and field scales, but conditions favoring the occurrence of observable preparatory processes are still largely unknown. In particular,

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 ...

Further Developments on the Geothermal System Scoping Model

, 2010
The fields of well construction and engineering, power plant construction and engineering, and reservoir engineering often proceed independently of one another. Yet the subsystems of a geothermal plant with which each of these fields is concerned need to

Fracture Network Characterization and Thermal Performance Prediction in Enhanced Geothermal Reservoirs Using Covariance Matrix Adaptation and Embedded Discrete Fracture Model

Water Resources Research, Volume 61, Issue 8, August 2025.
Abstract Fracture networks constitute essential conduits for fluid and heat transport in enhanced geothermal systems (EGSs), yet their characterization is challenging due to the inherent geological complexities. This study develops an integrated inversion framework for effective fracture network characterization.
