A part of the Bartin-Amasra basin is found convenient for enhanced coalbed methane recovery. The lithologic information taken from the Zonguldak TKJ were studied and the depths the coal seams and the locations of the wells were visualized to perform a reliable correlation between seams existed in the area. According to the correlations, 63 continuous coal layers were found. The injection wells were located to the north and south parts of the reservoir where the depths are higher, so that injected CO2 can push the lighter methane to the production wells at the central and higher parts. The CO2 injection rate held constant throughout the simulation period at 30 Mscf. The production wells were constrained with minimum bottomhole pressure of 50 psi. CO2 can be injected as soon as the methane production starts. Injected CO2 reached the production wells after a while. Although continuing the production led to higher methane production, the main aim was to sequester the CO2. Therefore, the production was ceased at the wells which CO2 breakthrough occurred.

Modelling of ECBM recovery from Amasra Coalbed in Zonguldak Basin, Turkey
Sınayuç, Çağlar (2018-01-01)
Bartin-Amasra coal field was found convenient for enhanced coalbed methane (ECBM) recovery among the other fields in Zonguldak Coal Basin, Turkey. The lithologic information were examined and the depths of the coal seams and the locations of the wells were visualized to perform a reliable correlation between 63 coal layers existed in the area. The initial methane in place found in the coal layers both in free and adsorbed states were estimated using probabilistic simulations resulted in possible reserve (P1...
Natural gas hydrate potential of the Black Sea
Parlaktuna, Mahmut (2001-04-01)
The Black Sea is among the regions that have been cited in the literature as having conditions suitable for natural gas hydrate reserves. Russian scientists confirmed by seismic studies that there are five regions in the Black Sea which are highly promising for hydrate formation. In this study, conventional petroleum engineering methods are utilized to estimate the possible amount of gas available in one of the Black Sea Basins.
Investigation of gas hydrate potential of the Black Sea and modelling of gas production from a hypothetical Class 1 methane hydrate reservoir in the Black Sea conditions
Merey, Sukru; Sınayuç, Çağlar (2016-02-01)
Gas hydrate deposits which are found in deep ocean sediments and in permafrost regions are supposed to be a fossil fuel reserve for the future. The Black Sea is also considered rich in terms of gas hydrates. It abundantly contains gas hydrates as methane (CH4 similar to 80-99.9%) source. In this study, by using the literature seismic and other data of the Black Sea such as salinity, porosity of the sediments, common gas type, temperature distribution and pressure gradient, it was estimated that up to 71.8 (...
Projections of climate change in the Mediterranean Basin by using downscaled global climate model outputs
Ozturk, Tugba; Ceber, Zeynep Pelin; Turkes, Murat; KURNAZ, MEHMET LEVENT (Wiley, 2015-11-30)
The Mediterranean Basin is one of the regions that shall be affected most by the impacts of the future climate changes on hydrology and water resources. In this study, projected future changes in mean air temperature and precipitation climatology and inter-annual variability over the Mediterranean region were studied. For performing this aim, the future changes in annual and seasonal averages for the future period of 2070-2100 with respect to the period from 1970 to 2000 were investigated. Global climate mo...
Development of a predictive model for carbon dioxide sequestration in deep saline carbonate aquifers
Anbar, Sultan; Akın, Serhat; Department of Petroleum and Natural Gas Engineering (2009)
Although deep saline aquifers are found in all sedimentary basins and provide very large storage capacities, a little is known about them because they are rarely a target for the exploration. Furthermore, nearly all the experiments and simulations made for CO2 sequestration in deep saline aquifers are related to the sandstone formations. The aim of this study is to create a predictive model to estimate the CO2 storage capacity of the deep saline carbonate aquifers since a little is known about them. To crea...
