Natural gas is a fossil fuel that is present in every step of our daily life, in terms of commercial, domestic, and industrial areas. It has wide low and high demand periods which necessitates its storage during low periods to be used during the high periods. One of the widely used storage methods is underground natural gas storage (UGS) facilities that have been used since 1915. They are economically important in long-term usage in the marketing area. Therefore, finding new suitable underground storage locations in Türkiye is getting strategically important. Apart from depleted oil or gas fields, salt domes and other salt bodies are widely used for this purpose. In this context, this study aims at mapping and evaluating the salt bodies in various parts of Türkiye using potential field data and seismic data sets and to design proper cavern patterns suitable for efficient underground storage facilities. For this purpose, two candidate sites are selected in Tuzgölü and Çankırı basins, which contain thick salt deposits and bodies suitable for constructing underground salt caverns for gas storage. The location of the salt bodies was determined by potential field data then they are mapped out using 2D seismic data sets. The 2D seismic interpretations are modeled in the Leapfrog Geo software for generating 3D static (solid) volumes. Then, the underground salt cavern is designed based on the analytical solution method that takes the shape of the salt body and geomechanical properties into consideration.

Critical evaluation of the energy resources of Turkey with respect to the world prospects Aydemir, Mehmet Olcay; Mehmetoğlu, Mustafa Tanju; Department of Petroleum and Natural Gas Engineering (2010) Existing petroleum and natural gas reserves, which are the major supplies of primary energy demand of the world, are cumulated in a few countries. This causes a serious supply security problem for many countries. On the other side, greenhouse gas emissions caused by mainly fossil fuels are gradually increasing to a point which jeopardizes the future of the earth. By now, countries have to consider both their supply security and this global environmental problem while planning their energy future. For Turkey...
An overview of underground coal gasification and its applicability for Turkish lignite Pekpak, E.; Yoncaci, S.; Kilic, M. G. (2010-05-26) It is accepted that coal is going to maintain its significance as an energy source for longer time than oil and natural gas. Environmental concerns brought about the concept of clean coal technologies in the recent years. Coal gasification is one of the clean coal technologies. It may be applied on the surface for the mined coal or in-situ. Gasification of coal in-situ is called "Underground coal gasification" (UCG) and has several advantages over surface gasification and conventional mining. UCG provides l...
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...
Challenges related to flotation cleaning of oil shales Issues due to compositional and surface features and post grinding surface behavior Altun, Naci Emre (2016-09-30) Oil shale is an important energy resource alternative. Despite its recognition as an unconventional oil source, oil shale is also considered as an important solid fossil fuel alternative to coal and lignites due to the solid form and remarkable extent of organic content. Utilization possibilites, similar to coal and lignites, have been considered in the past decades and direct use of oil shales in thermal power production has been possible in countries like Estonia and China. In the perspective of utilizati...
Comparison of Mechanical Behaviour of G Class Cements for different Curing Time Güner, Doğukan; ÖZTÜRK, HANDE IŞIK (2015-04-17) Since 1900's, well cementing is one of the most substantial method in casing application of oil, gas and geothermal. The American Petroleum Institute (API) identifies well cements in 8 classes with respect to pressure, temperature and the depth of the well. G class cement is the most commonly used cement type for well casing purpose due to its sulphate resistance ability. High sulphate-resistant (HSR) G class cements are often used in well cementing industry. API Standards mainly focus on uniaxial compressi...
