From: Optimizing scenarios of a deep geothermal aquifer storage in the southern Upper Rhine Graben
Pressure distribution in the Buntsandstein aquifer at the end of the storage cycle after 175 d injection of heated water (80 °C) into the well BS-North and production via well BS-South (red line); rates Q = 10 L s−1. The ‘blue line’ refers to the pressure distribution in the same aquifer at the end of the heating cycle, i.e., production from well BS-North and injection of colder water (50 °C) into BS-South. Please note the influence of the fault in vicinity of the well BS-South (Fig. 5) on pressure distribution in the aquifer
