Geothermal energy has been identified as a renewable and environmentally friendly energy source, however, at present commercial geothermal energy production is limited to conventional geothermal resources. Hot dry rock systems are considered as unconventional geothermal resources which require engineering techniques to enhance the factors affecting the energy production. This thesis has been aimed to evaluate the coupled effects of the hydro-thermo-mechanical and chemical behaviour of hot dry rock systems with hydraulic and thermal stimulation techniques to understand the optimum conditions to enhance the permeability of the reservoir through a comprehensive research that includes advanced laboratory testing, numerical simulations and mathematical modeling.
