(Top) the horizontal stress ratio over the line connecting injection to producer well relative to the absolute pressure and temperature solutions after 50 years of production in the case of no fault offset. (Bottom row) the effect of varying reservoir matrix permeabilities on the pressure solution (Van Wees et al. 2012) and the horizontal stress ratio along the orientation of the geothermal doublet. The horizontal stress ratio around the injection well is highlighted to emphasize the near wellbore region. The fault geometry is outlined in grey
