Journal Article: Kizildere Geothermal Field - Western Anatolia

In the framework of the geothermal energy survey of the western Anatolia Project, sponsored by the Mineral Research and Exploration Institute of Turkey and the United Nations, a geothermal field of apparently commercially exploitable size was discovered in the Saraykoy-Denizli geothermal area, western Anatolia, in the year 1968. Geological, gravity and resistivity surveys of the area had been undertaken by the Mineral Research and Exploration Institute of Turkey prior to the implementation of the Project in 1967. Additional resistivity, seismic and gradient surveys, geological and geochemical investigations, resulted in the location of a first geothermal testwell. The KD No. I well was drilled in spring 1968 and became the discovery well of the Kizildere field. The wells drilled in the Kizildere geothermal field area indicate that this field can produce a mixed geothermal flow from which steam can be flashed off in commercial quantities. Production is from fractured Lower Miocene limestones, below an argillaceous caprock and from the metamorphic basement composed of schists and dolomites. The Kizildere geothermal field is located on a positive fault block complex on the north flank of the Big Meander graben and production has already been established on several fault blocks. The structure of the Kizildere field area is fully confirmed by resistivity surveys. The Kizildere field area is characterized by geothermal gradients between 3 and 5°C/10 m. This field has been discovered by rigorous application of geological, geophysical and geochemical investigations of an area where there is no recent volcanic activity but only some hot springs. Six deep testwells have been completed on this field, to date, all producing a mixed flow. At present, accurate mass and steam flow measurements indicate that one of the wells has a potential of 30 t/h of dry steam, and 250 t/h of hot water at a wellhead pressure of 4 to 5 ata. Stabilized reservoir temperatures are between 185 and 200°C. The Turkish Government is planning to set up as soon as possible a pilot geothermal electric plant near one or two of the most productive wells.
