(Top row) stress and temperature solutions on the fault plane for the scenario in which the injection well is located at a distance of 300 m from the fault in the case of normal fault offset at (left) the arrival of the thermal front on the fault plane, after (middle) passing of the thermal front and (right) when thermal breakthrough occurs in the production well. (Bottom row) the relative difference between both approaches on the fault pillar is presented over the production lifetime of the geothermal doublet. A positive difference indicates MACRIS to predict a larger stress response compared to the uniaxial solution. The reservoir geometry is outlined in grey/black
