Flow and tracer transport in a single fracture at non-isothermal conditions
Tavakkoli Osguei, Yashar; Akın, Serhat (2022-11-01)
Assessing preferential flow that occurs through small fractures or permeable connected pathways of other kinds is important to many processes but is difficult to determine, since most chemical tracers diffuse quickly enoug...
Advanced workflow for multi-well tracer test analysis in a geothermal reservoir
Bayer, Peter; AKIN, TAYLAN; Akın, Serhat (2022-05-01)
Interpretation of tracer tests in geothermal reservoirs is carried out by fitting the measured data either with simplified two-dimensional (2-D) analytical solutions or with complex numerical models. Available analytical s...
Fluid-CO2 injection impact in a geothermal reservoir: Evaluation with 3-D reactive transport modeling
AKIN, TAYLAN; Baser, Ali; Saracoglu, Onder; Akın, Serhat (2022-01-01)
Geothermal energy is commonly recognized as an environmentally friendly source of energy. However, geothermal fluids have unusually high CO2 content, particularly, in carbonated geothermal reservoirs. An efficient method t...
Optimization of Production and Injection of Geothermal Fields: A Machine Learning Approach
başer, ali; KÜÇÜK, SERHAT; saraçoğlu, önder; şentürk, erdinç; Akın, Serhat (2021-10-01)
Optimizing field injection and production requires a calibrated numerical model, typically consisting of thousands of grid blocks. Optimization carried out using such a model usually takes a very long time. If the numerica...
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 pr...
A Predictive Model of Wellbore Performance in Presence of Carbon Dioxide in Kizildere Geothermal Field
saraçoğlu, önder; başer, ali; AKIN, TAYLAN; KÜÇÜK, SERHAT; şentürk, erdinç; Akın, Serhat (2021-10-01)
Typically, geothermal wellbore model is used to predict the production performance of wells using a wellbore simulator based on flow tests. An iterative procedure is used to calibrate NCG content. In this study, a predicti...
CO2 Decline in Alaşehir (Turkey) Geothermal Reservoir
Akın, Serhat; Aydın, Hakkı; AKIN, TAYLAN (2021-10-01)
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 res...
Reinjection Optimization of Kızıldere Geothermal Field for Sustainable Reservoir Pressure Management
KÜÇÜK, SERHAT; başer, ali; saraçoğlu, önder; şentürk, erdinç; tüzen, mahmut kaan; Akın, Serhat (2021-10-01)
Pressure decline with respect to time is one of the main concerns in geothermal field management. In order to maintain the reservoir pressure, a sustainable reinjection strategy is needed. In this study, a numerical model ...
Transient shape factors for dual-porosity simulation of tight rocks
Kilicaslan, Ufuk; Akın, Serhat (2021-05-01)
The shape-factor concept provides an elegant and powerful upscaling method for fractured reservoir simulation. Many different shape-factors, among which the well-known Warren and Root, and Kazemi shape-factors have been pr...
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 s...
