Integrated 3-D finite element simulation of the Edremit geothermal system
Yoğurtçuoğlu, Alp; Karahanoğlu, Nurkan; Department of Geological Engineering (2016)
The Edremit Geothermal system consists of a shallow cold aquifer and a hot reservoir layer at depth. A 3-Dimensional Finite element model with 65596 nodes is used to simulate this system by an integrated algorithm in a 3 km by 3 km with 300 meters of depth study area consisting of currently operating geothermal field deep water wells. To determine the permeability values and hydraulic gradient values in the study area, a 2-Dimensional simulation was performed with 27664 nodes for the entire Edremit Basin, a...
Simulation of geothermal reservoirs with high amount of carbon dioxide
Küçük, Serhat; Akın, Serhat; Department of Petroleum and Natural Gas Engineering (2018)
Geothermal energy is always attributed as a sustainable and environmentally friendly source of energy. But in some cases, amount of the greenhouse gas emissions from geothermal fields become a big issue. Kızıldere Geothermal Field, one of the most important and large scale geothermal fields of the world, is a subject of these issues, experiencing excess amount of CO2 production rates and a rapid decline in the reservoir pressures. This study aims to construct a numerical model of the Kızıldere Geothermal Fi...
Numerical modeling of Edremit geothermal field
Günay, Emre; Karahanoğlu, Nurkan; Department of Geological Engineering (2012)
The purpose of this study is to examine the geothermal potential, sustainability, and reinjection possibility of Edremit geothermal field. In order to investigate this, a numerical model consisting of a hot and cold water aquifer system is established. A two dimensional cross sectional model is set to simulate this geothermal system. Different pressure and temperature values are applied to the nodes at the boundaries to perform a steady state calibration which minimizes the computed results and observed val...
Multiple criteria sorting methods based on support vector machines
Duman, Aslı; Karasakal, Esra; Department of Industrial Engineering (2010)
This study addresses sorting problems with predefined ordinal classes. We develop a new method based on Support Vector Machine (SVM) model, which is mainly used for nominal binary or multi-class classification processes. In the proposed method, the SVM model is extended to include the preferences of the decision maker and the ordinal relationship between classes in sorting problems. New sets of constraints are added to the SVM model. We demonstrate the performance of the proposed method through several data...
Application of fluorescent melamine resin microspheres for use as a geothermal tracer
Salar, Mustafa; Akın, Serhat; Department of Petroleum and Natural Gas Engineering (2018)
Tracer testing of flow between injection and production wells is an effective tool to map fluid flow pathways in a geothermal reservoir. Tracer concentration curves can be used to provide insight into projected thermal drawdown in the reservoir or thermal breakthrough of re-injected fluids, estimating inter-well volumes and flow geometries. Although radioactive tracers have been used in the past, many tracer tests now use chemical tracers that are less hazardous to handle. Fluorescent organic compounds such...
