This study was performed considering that low to medium enthalpy geothermal areas are important besides the geothermal fields with high temperature located in Western Anatolia for heating, thermal tourism and agricultural applications. It was also aimed at obtaining fluids at high temperature in areas which were observed at a temperature relatively lower than the surface temperature. The study area is located at a region between the towns of Menderes and Seferihisar to the south-southwest of Izmir. This is a multidisciplinary investigation which obtained fluids and studied the geothermal energy potential of the area. Field studies were finalized carrying out geological prospection and detailed geological prospection, hydrogeological, hydrogeochemical, geophysical and drilling studies which formed a potential for geothermal energy. As a result of these studies, the fluid with a flow rate of 104 tons per hour and a temperature of 141,18oC was obtained in the form of vapor + water with compressor machine. This fluid was obtained at a depth of 1215,50 m in the conducted exploratory drilling around Akyar Tepe. It was seen that the fluid obtained is sodium chloride type water and consists of a mixture of hot spring, surface water and marine water. This, which had been known as the low temperature field was introduced as a medium-high enthalpy geothermal system.
