| Abstract | Kizilcahamam is a low temperature (~ 80°C) geothermal field located 70 km from Ankara, Turkey. The produced geothermal water is used to heat more than 2500 houses. In order to characterize the reservoir, a tracer-test was planned using the efficient hydrologic tracer-test design technique. The test was carried out by injecting a slug of fluorescein into a shallow re-injection well. Analysis of the results showed that the injection well and the producers are interconnected. Analysis of time-concentration curves showed that a multi-fracture model represented the multi-peaked curves better than the others, which included homogeneous porous and double porosity models. The results are consistent with the conceptual geological models proposed in the literature. |
