Assessment of low temperature geothermal resources

Arkan, Serkan
One of the most applicable methods of low-temperature geothermal resource assessment is volumetric method. While applying volumetric method, the values of uncertain parameters should be determined. An add-in software program to Microsoft EXCEL, @RISK, is used as a tool to define the uncertainties of the parameters in volumetric equation. In this study, Monte Carlo simulation technique is used as the probabilistic approach for the assessment of lowtemperature Balçova-Narlidere geothermal field. Although Balçova-Narlidere geothermal field is being utilized for several direct heat applications, there exists limited data for resource assessment calculations. Assessment studies using triangular and uniform distribution type functions for each parameter gave the mean values of recoverable heat energy of the field as 25.1 MWt and 27.6 MWt, respectively. As optimistic values (90%), those values were found as 43.6 MWt and 54.3 MWt. While calculating these numbers, a project life of 25 years with a load factor of 50% is used.


A technical feasibility study on the use of Çavundur geothermal field for greenhouse heating
Kasapoğlu, Hüseyin; Parlaktuna, Mahmut; Department of Petroleum and Natural Gas Engineering (2003)
Protective cultivation is widely used nowadays in order to increase crop yield by creating the optimum conditions such as temperature, humidity and CO2 content, irrespective of outside conditions. Since plant production doubles for every 10 degrees increase in temperature to a certain limit, this makes temperature a very important factor for optimum plant growth. In order to keep the greenhouse temperature constant during changes in outside conditions, heating and often cooling are required. Heating of a gr...
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...
Application of non-market economic valuation method to value the environmental benefits of geothermal energy in monetary terms
Horasanlı, Erol; Alp, Emre; Department of Environmental Engineering (2010)
Determining environmental economic benefits of geothermal energy is difficult since there is no market for all environmental goods and services related to it. In order to determine and measure the market price of non-market goods and services, non-market valuation methods are used. Since intangible benefits do not have monetary values, non-market valuation techniques are applied to estimate them. Non-market valuation methods are important tools for policy makers in the cost and benefit analysis and environm...
Structural controls on Kızıldere geothermal field, Denizli-Turkey
Aksu, Baykan; Kaymakcı, Nuretdin; Department of Geological Engineering (2019)
Kızıldere geothermal field is one of the hottest fields located in south-western Anatolia and electricity has been produced from geothermal source since 1984. This high enthalpy geothermal field is located at the eastern edge of Büyük Menderes graben, which is one of the most active extensional structure belonging to the western Anatolian graben-horst system. Büyük Menderes graben, which hosts numerous geothermal fields, is a 3 - 30 km wide, 170 km long, nearly E-W trending depression developed under the N-...
Simulation of environmental impact of an existing natural gas dehydration plant using a combination of thermodynamic models
Torkmahalleh, Mehdi Amouei; Magazova, Galiya; Magazova, Aliya; Rad, Seyed Jamal Hassani (2016-11-01)
A new approach was presented to improve the simulation results of an existing TEG based natural gas dehydration plant, using Aspen Plus software. Furthermore, the environmental impact of the plant was investigated. The plant consists of four main unit operations including an absorber, a flash tank, a stripper and a regenerator. Twelve thermodynamic models were assigned to these units. In the first step of the study, only one thermodynamic model was assigned to all of the units while in other steps, combinat...
