Poroelastic stress relaxation, slip stress transfer and friction weakening controlled post-injection seismicity at the Basel Enhanced Geothermal System

Communications Earth & Environment, 2023
Post-injection seismicity at the enhanced geothermal system of Basel, Switzerland, was caused by poroelastic stress relaxation of stabilized faults during injection, according to numerical simulations of the stress field applied on a fault network.

The injection-production performance of an enhanced geothermal system considering fracture network complexity and thermo-hydro-mechanical coupling in numerical simulations

Scientific Reports, 2023
The effect of fracture networks on EGS performance remains worth further investigation to guide the formulation of geothermal extraction strategy. We established models that account for thermo-hydraulic-mechanical (THM) coupling and that are based on the

Experimental study on the effect of CO_2 storage on the reservoir permeability in a CO_2-based enhanced geothermal system

Geothermal Energy, 2023
A CO_2-based Enhanced Geothermal System (CO_2-EGS) has dual benefits of heat extraction and CO_2 storage. Mineralization storage of CO_2 may reduce reservoir permeability, thereby affecting heat extraction.
