Germencik Geothermal Field, which is one of the oldest high enthalpy geothermal fields in Turkey, is operational since 2009. As of 2017, two 47.4 MWe dual flash and four 22.5 MWe binary power plants have been constructed to exploit liquid dominated reservoir with feed zone temperatures as high as 234C. In order to optimize re-injection a tracer test where three different naphthalene sulfonates tracers were simultaneously injected into three different re-injection wells, was conducted. Quantitative and qualitative analysis of tracer concentrations collected from 18 different production wells were used to identify connectivity between the re-injection and production wells. Three different tracer return curves were identified. It has been observed that flow velocity changed between 34.18 m/day to 3.12 m/day. The results showed that multi fracture model can be used to model tracer returns for most wells. However, flow – storage capacity plots showed that only a few wells produced from more than one fracture system.

Numerical simulation of germencik geothermal field
Hamendi, Ahmed; Parlaktuna, Mahmut; Department of Petroleum and Natural Gas Engineering (2009)
The Germencik Omerbeyli geothermal field is considered to be one of the most important geothermal fields in Turkey. A numerical modeling study was carried out to simulate the response of the field to different production/injection scenarios. The reservoir performance evaluation was based on the numerical simulation of the reservoir behavior using the simulation code TOUGH2. The numerical simulation model includes a total area of 85.8 km2 and extends from the surface at +330 m msl (mean sea level) to a depth...
Estimation of upcoming problems in Alaşehir geothermal field using a numerical reservoir model
Aydin, Hakki; Akın, Serhat (2021-04-01)
Alaehir geothermal area located in Alaehir Graben, West Anatolia, is the latest target for geothermal field development in Turkey. Seven different operators are developing the power capacity in this geothermal field on a strictly competitive and largely confidential basis without the significant exchange of resource information among them. Currently, eleven binary and combined flash-binary geothermal power plants with widely changing power generation efficiency between plants produce from the same reservoir...
Characterization and Comparison of geothermal fluids geochemistry within the Kızıldere Geothermal Field in Turkey: New findings with power capacity expanding studies
Tut Haklıdır , Füsun S.; Şengün, Raziye; Aydın, Hakkı (Elsevier BV, 2021-7)
The Kızıldere geothermal field is the first known high-temperature geothermal field in Turkey. The field is located in the Büyük Menderes Graben (BMG), Western Anatolia (Turkey). There are four production sections (reservoir-I, II, III, and IV) with different rock compositions and geochemical characteristics in the production area. Identifying and characterizing these production units may give a good insight into field development plans for a sustainable production. This study aims to characterize productio...
Practical Experiences About Reservoir Monitoring in Alasehir Geothermal Field
Aydın, Hakkı; Akın, Serhat; Tezel, Seray (2018-02-14)
Alaşehir geothermal area that is located in southern part of the Alaşehir Graben is one the important geothermal areas in Turkey. Currently, more than 6 operators are exploiting this field on a strictly competitive, and largely confidential, basis without significant exchange of resource information among them. This paper discusses monitoring of the response of part of Alaşehir geothermal system to large scale exploitation. In this regard, temperature and pressure of the reservoir, steam flowrate, brine flo...
Fractal Modeling of Outcrop Fracture Patterns in Alasehir Geothermal Reservoir Turkey
Gürel, Emrah; Coşkuner, Yakup Berk; Akın, Serhat (2016-02-24)
Alasehir geothermal area located in Gediz graben is the current high enthalpy geothermal target in Turkey. The geothermal system mainly produces from fractured Paleozoic Menderes metamorphics. In order to characterize the fractured reservoir formations, marble and schist outcrop fracture networks were identified and traced using image analysis software. Primary and secondary fracture histograms were developed and box counting method was used to calculate fractal dimension. It was observed that for both form...
