Abstract
The doctoral research has been carried out in the context of an agreement on joint doctoral supervision between RWTH Aachen University, Germany and Delft University of Technology, the Netherlands.
Geothermal energy stands as a promising avenue for low-carbon energy production. Traditional methods involve extracting hot water into one well and the injection of cold water in another, with hydrothermal systems relying on fluid flow through either pores or natural fractures in rock. Enhanced Geothermal Systems (EGS) are deployed in fractured/faulted rock settings where fluid flow is insufficient, necessitating enhanced permeability of fractures for improved heat transfer. Challenges persist in ensuring productivity, sustainability, and safety, with fault and fracture reactivation presenting significant concerns....
