Results for the scenario in which the geothermal doublet is oriented parallel to a bounding fault. (Top row) the shear stress solutions on the fault pillars at mid-reservoir depth when thermal breakthrough occurs in the production well in the case the doublet is located at a distance of (left) 750 m and (right) 300 m from the fault. (Bottom row) the corresponding stress and temperature solutions on the fault plane, focused on the pillar that is in line with the injection well (i.e. \(Y = 1750\;{\text{m}}\)). The reservoir geometry is outlined in grey/black
