Reinjection of gas free of brine into the peripheries of a geothermal reservoir may gradually decline non-condensable gas (NCG) concentration in the reservoir fluid during the operation of geothermal power plants. As a result, gradually decreasing gas emissions can be observed. In this study, we use separator data to calculate produced CO2 amount in the reservoir fluid. The data used is from the Alaşehir geothermal area that is certainly not the one and only target for geothermal production in Turkey. Data obtained from 7 wells covering two years of production showed that reinjection of gas free brine into the peripheries of the geothermal reservoir declined CO2 concentration in the reservoir fluid. It has also been observed that the commissioning of neighbor power plants has a significant effect on the produced CO2 amount.

Numerical reservoir simulation of Alaşehir geothermal field Aydın, Hakkı; Akın, Serhat (null; 2020-02-10) Use of a comprehensive reservoir simulation is essential for an effective geothermal reservoir management. TOUGH2 has become a widely used simulator for this purpose. In this study, one of the most exploited geothermal fields in Turkey, Alaşehir geothermal field has been modeled by using TOUGH2 reservoir simulator. The study includes more than 100 wells, which are operated by 7 different developers. The total installed capacity of geothermal power plants in the field is 212 MWe, but additional capacity (98 ...
Estimation of the formation temperature from the inlet and outlet mud temperatures while drilling geothermal formations Tekin, Sema; Akın, Serhat; Department of Petroleum and Natural Gas Engineering (2010) Formation temperature is an important parameter in geothermal drilling since it affects all the components of the system such as drilling fluid, drilling operations and equipment through mud temperatures. The main objective of this study is to estimate the formation temperatures of five geothermal wells in Germencik-Ömerbeyli geothermal field by using inlet and outlet mud temperatures obtained during drilling. For this purpose, GTEMP, a wellbore thermal simulation model is used to simulate the process of dr...
Carbon dioxide injection field pilot in umurlu geothermal field, Turkey Yücetaş, İsmet; Ergiçay, Nevzat; Akın, Serhat (null; 2018-01-01) The Umurlu geothermal reservoir located in Buyuk Menderes Graben, Turkey initially contained around 2% by weight CO_2 dissolved in geothermal reservoir fluid. The produced CO_2 rate declined over one year of production time due to dilution of reservoir gas by degassed injectate. Since CO_2 has a considerable role on Umurlu reservoir performance and energy production, produced non-condensable gas (NCG) has been injected simultaneously with colder degassed injectate from an injection well for the last two mon...
Assessment of production strategies of a gas condensate field using a black oil simulator: a case study Parlaktuna, Burak; Sınayuç, Çağlar; Department of Petroleum and Natural Gas Engineering (2015) Condensates are low-density liquids that are produced along with the gas phase from wet gas or gas-condensate reservoirs. Availability of these liquids makes gas-condensate reservoirs more profitable than the other gas reservoirs since condensates are gasoline like fluids with API gravities more than 45°. Although the condensate production is profitable, the management of gas-condensate reservoirs is challenging. Due to their nature, condensates condense and separate from the gas if the pressure drops below...
CO2 reduction in reverse flow reactors Aksu, Nevzat Can; Üner, Deniz; Atamer, İbrahim Bülent; Department of Chemical Engineering (2013) Syngas, a mixture of CO and H2, is a very important industrial gas mixture, because it can be used for synthesizing products such as synthetic natural gas, ammonia and methanol. The main purpose of this work was to obtain CO by CO2 reduction. Reducible metal oxides are used as catalysts due to the fact that they can be reduced and re-oxidized upon changes in temperature, pressure and gas atmosphere. CeO2 was chosen for this cyclic reaction pathway based on the reports on similar studies in literature. It is...
