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 of -4581 m msl. Through a trial and error process, the natural state model was satisfactorily matched with the initial temperature and pressure data measured at the wells. The natural state model was further calibrated using the long term flow test (LTFT) data conducted in 2006, including OB-6 and OB-9 as flowing wells and OB-8 as an injection well. The model was then used to predict reservoir performance under different production/injection scenarios over the next 30 years. Forecast runs showed that the pressure declines almost equally in all areas, consistent with the high permeability and connectivity of the reservoir, which had been established from the LTFT.

Numerical modeling of balçova geothermal field
Polat, Can; Parlaktuna, Mahmut; Department of Petroleum and Natural Gas Engineering (2010)
The aim of this study is to construct a numerical reservoir model for Balçova geothermal field, which is located in the İzmir bay area of the Aegean coast. A commercial numerical simulation program, TOUGH2 was utilized with a graphical interface, PETRASIM to model the Balçova geothermal field. Natural state modeling of the field was carried out based on the conceptual model of the field, then history matching of production – injection practices of the field was established for the period of 1996 – 2008. The...
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...
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...
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...
Hydrogeochemical Properties of Geothermal Fields at Northeastern Anatolia
Aydın, Harun; Karakuş, Hüseyin; Mutlu, Halim; Güleç, Nilgün Türkan; Hılton, Davıd (null; 2016-05-16)
In Anatolia which is one of exceptional continental regions hosting both Neogene volcanism and tectonism, the geothermal potential is quite high due to unique geological and tectonic structures. In recent years, the geothermal resources in western Anatolia, whose geothermal potential is well defined, are successfully used in a wide range of applications such as energy production, district heating, thermal tourism and greenhouse heating. However, the geothermal resources of northeastern Anatolia (NEA) have b...
