Reinjection Optimization of Kızıldere Geothermal Field for Sustainable Reservoir Pressure Management

Pressure decline with respect to time is one of the main concerns in geothermal field management. In order to maintain the reservoir pressure, a sustainable reinjection strategy is needed. In this study, a numerical model of Kızıldere Geothermal Field is constructed, which is then used to assess the current shallow reinjection/deep production strategy. According to the output of the numerical simulation, a new reinjection strategy is proposed. It has shown that more sustainable and reliable reinjection strategy can be applied by diverting the reinjection water from the shallow wells to the existing deep wells.
