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 production sections of the Kızıldere geothermal field using geology, hydrogeochemical properties such as chemistry, stable isotope, and non-condensable gas compositions. The results of gas and water analysis showed that geothermal fluids are of a meteoric origin in all producing sections. It was also found from the analyses that more intensive water-rock interactions take place as the reservoir temperature irises. Based on the different geochemical characteristics of each producing section, we thought that impermeable sediments like mica-schists and chlorite-schists lying between the reservoir units act as a seal. In light of this study, it can be concluded that the Kızıldere geothermal reservoir is very heterogeneous due to vertically compartmentalized reservoir sections that require a unique injection-production configuration for a sustainable production lifetime.

Geothermal resource assessment of the Gediz Graben utilizing TOPSIS methodology
Cambazoglu, Selim; Yal, Gozde Pinar; Eker, Arif Mert; Sen, Osman; Akgün, Haluk (Elsevier BV, 2019-07-01)
The Gediz Graben possesses the second highest geothermal power generation potential in Western Anatolia, Turkey. In this study, the geothermal resource potential of the Gediz Graben has been assessed by following an ideal point methodology. For this purpose, nine criteria layers were introduced into a GIS environment, namely, distance to faults and fault density, distance to cap rock units, hot springs and graben center, Gutenberg-Richter b-value map, night-time surface temperature, NDVI and slope. Each lay...
Comprehensive tracer testing in the Germencik field
Akın, Serhat (null; 2018-02-14)
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 qual...
Characterization of Kızılcahamam Geothermal field by tracer testing
Kaya, Tevfik; Akın, Serhat; Department of Petroleum and Natural Gas Engineering (2005)
Kızılcahamam Geothermal Field which is 70 km far from Ankara, has been utilized for Geothermal District Heating System, 25 MWt, 2500 residences capacity, greenhouses heating, thermal facilities since 1994. The average production rate is 350m3/h during the heating season , 150m3/h during the summer season for hot water and yearly average reinjection rate is 114m3/h from the field. The long term projections has been studied concerning on expected pressure decline by matching 10 years field history data which ...
Evolution of Balcova Geothermal District Heating System Turkey
Parlaktuna, Mahmut (null; 2015-04-23)
Balçova geothermal field is located in a densely populated area which makes direct heat applications very efficient and economical. Heat produced from Balçova geothermal field is utilized for three main purposes: greenhouse heating, balneology and residential heating. Among these three applications, the latter one is the main application throughout the Balçova Geothermal District Heating System (BGDHS). The field produces hot water from two different horizons: one shallow and one deeper zone. This paper pre...
Design of anchorage and assessment of the stability of openings in silty, sandy limestone: a case study in Turkey
Akgün, Haluk (Elsevier BV, 2004-01-01)
This study presents a procedure for the design of anchorage and for the assessment of the stability of openings in silty, sandy limestone through investigating the geotechnical problems of the Hasankeyf historical settlement area in southeastern Turkey, of which a good portion will stay below the reservoir of the proposed Ilisu dam. Rock mass characterization was performed. The RMR and GSI methods were utilized for rock mass classification. The RocLab software was used to determine the shear strength parame...
