Oil shales, which are kerogen-rich sediments, are one of the most important energy alternatives. The widely distributed deposits around the world and their vast amounts make them a promising option as a source of oil or as a solid fuel supplement. Nevertheless, the economics of retorting does not allow their utilization for oil production on a large scale with a few exceptions. Oil shale is an important potential energy resource for Turkey, being the second largest fossil energy source after lignite. This paper aims to emphasize the important aspects about oil shales so as to give ideas about their importance as an alternative source. The definition of oil shale, mode of occurrence and the use of resources in the world and in Turkey are reviewed and the opportunities for prospective utilization in the future are provided.

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...
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 to mitigate the CO2 emissions of geothermal power plants is to re-inject the captured CO2 with the effluent fluid to mineralize mainly into calcite under reservoir conditions (e.g., reservoir temperatures ranging from 200 to 220 degrees C). One of the major concerns about the re-injection o...
Experimental analysis of adsorption capacities and behaviors of shale samples
Merey, Şükrü; Sınayuç, Çağlar; Department of Petroleum and Natural Gas Engineering (2013)
In recent years, unconventional reserves such as shale gas reservoirs have become a major alternative source of energy in the world. It is known that Turkey has shale gas potentials especially in the Southeastern and Thrace region. In shale gas reservoirs, significant amounts of natural gas exist as conventional “free” gas in porous spaces as well as “adsorbed” gas on shale matrix. Understanding adsorption capacities and behaviors of shale gas reservoirs may help exploitation and resource evaluation. In thi...
Flexibility modelling of natural gas contracts: İstanbul case
Yazıcı, Caner Fuad; Kestel, Sevtap Ayşe; Kalaycı, Erkan; Department of Financial Mathematics (2016)
Natural gas is one of the main energy source in the world and plays an important role in energy demand. The liberalization process in the natural gas market has shifted the focus on the Local Distribution Companies (LDCs) which make the procurement and transportation decisions. The decisions such as the pipeline sales, Liquefied Natural Gas (LNG) sales, other sources of natural gas procurement, transportation and storage opportunities provide the LDCs an opportunity to trade the natural gas in a least-costs...
Numerical simulations of gas production from Class 1 hydrate and Class 3 hydrate in the Nile Delta of the Mediterranean Sea
MEREY, ŞÜKRÜ; Longinos, Sotirios Nik (Elsevier BV, 2018-04-01)
Gas hydrate reservoirs are considered as near-future energy resources in the world. As well as the many places in the world, there is also gas hydrate potential in the Mediterranean Sea. In this study, by using the literature data, it was aimed to understand whether the Mediterranean Sea includes necessary parameters for producible gas hydrate reservoirs. It was shown that the Mediterranean Sea contains all of these parameters (source gas, appropriate pressure and temperature, coarse sand potential, etc.). ...
