Due to the attractive feed-in-tariff mechanism, Turkish geothermal producers operate geothermal power plants at their maximum capacity. As a result, many geothermal reservoirs in Turkey have been exploited with an aggressive production strategy by multiple operators. A significant amount of production targeted natural fractures associated with normal faults in Western Anatolia. Wells produced at the maximum allowable capacity caused substantial reservoir pressure drops that affected reservoir dynamics. Premature temperature decline, local pressure drop, and the sharp decline of non-condensable gases (NCG) have been commonly observed in these geothermal reservoirs. All of these impacted the production performance of wells negatively. Artificial lifting methods such as airlifting and downhole pumps (Line shaft pumps or electrical submersible pumps (ESPs)) are commonly used to compensate for missing production. This study discusses the use of ESPs in liquid dominated high-temperature Alaşehir and Kızıldere fields. Observations, experiences, and lessons learned from the ESP applications in these fields are reported in detail.

Design of Electrical Submersible Pump system in geothermal wells: A case study from West Anatolia, Turkey Aydın, Hakkı; Merey, Şükrü (Elsevier BV, 2021-5-12) Geothermal is defined as one of the renewable and sustainable energy sources. The sustainability of geothermal wells is highly dependent on the pressure drive mechanism and non-condensable gas (NCG) content of the produced geothermal fluid. Pressure decline and decline of non-condensable gases are commonly observed in geothermal production wells, which is unfavorable for wells’ lifetime. Electrical Submersible Pumps (ESP) are one of the solutions for extending the lifetime of geothermal wells. In this study...
Soil CO2 Flux and Temperature Measurements in Kızıldere Geothermal Field KÜÇÜK, SERHAT; başer, ali; saraçoğlu, önder; AKIN, TAYLAN; şentürk, erdinç; tüzen, mahmut kaan; Akın, Serhat (2021-10-01) Geothermal fields in Turkey have substantially higher carbon dioxide content compared to a typical geothermal field in the world. Geothermal Emission Control (GECO) project aims to reduce carbon emissions by reinjecting produced carbon dioxide from a pilot reinjection well. A high-resolution CO2 flux meter is used to measure the surface carbon dioxide flux and temperature parameters in Kızıldere field, which is one of the demonstration fields in this project. The aim of these measurements is to map the natu...
Hydraulic characteristics of modified tyrolean type intakes Yılmaz, Kuta; Göğüş, Mustafa; Department of Civil Engineering (2019) Today, besides the dams, construction of runoff-river type hydroelectric power plants are also important for producing the required electricity. Among the runoff-river hydroelectric power plants, Tyrolean type intakes are very popular as they do not need reservoirs. These intakes are mostly constructed on rivers which carry sediment and have large slopes. The inclination angle of the rack, θ, rack length, L, and the rack spacing, e, are the most important parameters that determine the amount of sediment tha...
Solar repowering of Soma-A thermal power plant YILMAZOĞLU, MUSTAFA ZEKİ; DURMAZ, Ali; Baker, Derek Keıth (2012-12-01) In this study, solar repowering of the Soma-A thermal power plant in Turkey is investigated using simulations. The Soma A thermal power plant began operation in 1957 and has served until 2010. In the current situation the installed capacity of the power plant is 44 MWel with two units. In the simulations full load and part load operations are considered and compared for three different cases: (1) current case; (2) solar steam generation; and, (3) solar feed water heating. Economic analyses are performed by ...
Structural, lithological, and geodynamic controls on geothermal activity in the Menderes geothermal Province (Western Anatolia, Turkey) Roche, Vincent; Bouchot, Vincent; Beccaletto, Laurent; Jolivet, Laurent; Guillou-Frottier, Laurent; Tuduri, Johann; Bozkurt, Erdin; Oguz, Kerem; Tokay, Bülent (2019-02-01) Western Turkey belongs to the regions with the highest geothermal potential in the world, resulting in significant electricity production from geothermal resources located predominantly in the Menderes Massif. Although geothermal exploitation is increasingly ongoing, geological, and physical processes leading to the emplacement of geothermal reservoirs are hitherto poorly understood. Several studies on the Menderes Massif led to different interpretations of structural controls on the location of hot springs...
