| Abstract | Kizildere Geothermal Field, Turkey, which is one of the oldest high enthalpy geothermal fields in Turkey is in third development stage. In order to optimize re-injection a tracer test where four tracers (Fluorescein and 3 different naphthalene sulphonates) were simultaneously injected into four different re-injection wells, was conducted. Quantitative and qualitative analysis of tracer concentrations measured using HPLC were used to identify connectivity between the re-injection and production wells. Flow – storage capacity plots were used to identify flow geometry. It has been concluded that tracer return patterns slightly changed in some production wells. The results showed that a single fracture model can be used to model tracer returns for most wells. Finally a capacitance resistance model was to confirm tracer results. |
