Many gas seepages, temperature, pressure, salinity, anoxic environment and high source gas potential of the Black Sea indicates that the Black Sea might have huge potentials for biogenic and thermogenic gas hydrates. However, the last important parameter to consider gas hydrate as an energy source is the type of sediments. Coarse marine sands are considered as good hydrate reservoirs because of high porosity and high permeability. Only very limited data is available related to the types of lithology of the Black Sea sediments. Hence, in this study, the literature data (especially the drilling and coring data of DSDP Leg 42B program) about gas seepages, temperature gradient, pressure gradient, salinity, anoxic environment and high source gas potential, and the types of the sediments in the Black Sea were investigated and analyzed. Although gas seepages, temperature gradient, pressure gradient, salinity, anoxic environment and high source gas potential of the Black Sea are appropriate for producible gas hydrate reservoirs, the sediments of the Black Sea appear to be generally fine grained with high clay content. Sandy-silt and silty sand layers in turbidites of the Black Sea might be potential producible hydrate reservoirs but these sediments are fine. As well as turbidites, separate thin sand layers might be potential gas hydrate reservoirs as an energy source in the Black Sea.

Reservoir heterogeneity of Ordovician sandstone reservoir (Bedinan Formation, SE Turkey): Diagenetic and sedimentological approachs Yildiz, Gokay; Yılmaz, İsmail Ömer (Elsevier BV, 2020-08-01) The sandstone-bearing reservoir levels (Bedinan Formation) in the Diyarbakir Basin, SE Turkey show strong heterogeneity in porosity, permeability and capillary pressure, which influences oil production rates of the studied 6 wells and beclouds the prediction of hydrocarbon reserves. Therefore, comprehensive understanding of the sandstone reservoir characteristics has been necessitated to optimize its ultimate hydrocarbon recovery, maximize its lifetime and to make more accurate performance predictions for t...
Analysis of Plio-Quaternary deep marine systems and their evolution in a compressional tectonic regime, Eastern Black Sea Basin Sipahioglu, N. O.; Karahanoğlu, Nurkan; Altıner, Demir (Elsevier BV, 2013-05-01) Facies architecture of submarine fans and channel-levee complexes in the Eastern Black Sea Basin and their evolution from the Late Miocene until the present day are studied using a three-dimensional seismic data set covering an area of approximately 1161 km(2). The interpretation of the observations reveals the outcome of the changing interplay between rate of sedimentation and compressional tectonism in the area through time.
Evaluation of coal and water samples from Manisa-Soma-Deniş region conccerning Balkan Endemic Nephropathy and determination of Balkan Endemic Nephropathy risk Öztürk, Mehmet Sinan; Önen, A. Pırıl; Department of Geological Engineering (2006) The water and coal samples from the Manisa-Soma-Deniş region were studied on the basis of their basic characteristics, inorganic and organic parameters. Coal samples were determined as low-quality lignite. They have high concentrations of arsenic, uranium and lead. The organics in the coal samples are of aliphatic hydrocarbons and their derivatives (alkanes and alcohols), methyls, phthalates, naphtalenes and benzenes. They are inactive and low in concentrations. Water samples have basic characteristics with...
Assessment of shrinkage-swelling influences in coal seams using rank-dependent physical coal properties Balan, Huseyin Onur; Gumrah, Fevzi (Elsevier BV, 2009-01-07) Characterization of coal reservoirs and determination of in-situ physical coal properties related to transport mechanism are complicated due to having lack of standard procedures in the literature. By considering these difficulties, a new approach has been developed proposing the usage of relationships between coal rank and physical coal properties. In this study, effects of shrinkage and swelling (SS) on total methane recovery at CO2 breakthrough (TMRB), which includes ten-year primary methane recovery and...
Monitoring of chemical and isotopic compositions of geothermal waters along the North Anatolian fault zone Süer, Selin; Güleç, Nilgün Türkan; Department of Geological Engineering (2004) This study aims to determine the chemical (anion-cation) and isotopic compositions (d18O-dD-3H) of the geothermal waters along the North Anatolian Fault Zone (NAFZ) and highlight any possible seismicity-induced temporal variations during the course of two years (2002-2003) monitoring programme. The geothermal sites are alligned along a 800 km transect of the NAFZ and are, from west to east, Yalova, Efteni, Bolu, Mudurnu, Seben, Kursunlu, Hamamözü, Gözlek and Resadiye. The thermal waters of NAFZ are dominant...
