This study provides an overview for the carbon dioxide sequestration process in an oil reservoir by using the software CMG's GEM. Different scenarios are applied for the oil reservoir description. Firstly, a single layered reservoir is considered and simulation studies are performed, as this reservoir is homogeneous, heterogeneous and fractured. Secondly, a multi-layered reservoir is examined. In the second case, a heterogeneous system and a heterogeneous system composed of homogenous layers are selected. For these two arguments, it is assumed that injection perforation is in the bottom layer and production perforation is in the top layer. As a third argument of multi-layered reservoir, a heterogeneous system composed of homogenous layers is selected and it is assumed that all layers are perforated for both injection and production. Finally, the effects of those properties on CO2 injection capacity, cumulative oil and gas production are discussed. In the single layered reservoir cases, cumulative oil production and CO2 injection capacity increase by reason of heterogeneity. When the system is fractured, cumulative production, CO2 injection and storage capacity decrease due to rapid increase in pressure as a consequence of low porosity. For the multi-layered reservoir, the case of homogeneous layers with two perforation intervals produces higher hydrocarbon recovery, amount of CO2 injection and storage. When CO2 is injected to all layers, pressure increases more rapidly, resulting in abridged time of injection. Hence, cumulative oil and gas production and mass of CO2 injected are restricted.

Characterization and Development of Drilling Fluid Type for an Oil Field
Kök, Mustafa Verşan (Informa UK Limited, 2010-01-01)
In this study, different types of drilling fluids are developed and analyzed for a mature oil field. The optimum conditions were developed for shallow and deep formations. The experimental procedure that was followed for viscosity, fluid loss, density, and pH calculations is based on the standards dictated by API RP 13B. At the end of the experiments, it was also observed that for shallow depths, 0.2-0.3 lb of caustic soda will be enough for one barrel of drilling fluid. On the other hand, lignosulphanate t...
Computation of instantaneous fuel consumption for the determination of combustion efficiency with special reference to coal briquette size
Altun, Naci Emre; Bagci, AS (Informa UK Limited, 2006-04-01)
This study comprises of the computation of instantaneous fuel consumptions as a straight means for the interpretation of combustion-related characteristics of coal. The model relies on the determination of the extent of combustion by the calculated fuel combustion amounts at specific instants in order to examine the oxidation behavior and possible influences governed by any variable of interest. In this context, coal briquettes prepared by varying dimensions with and without a volume constraint were evaluat...
Parametric Study of Carbon Dioxide Sequestration in Deep Saline Aquifers
Basbug, B.; Gumrah, F. (Informa UK Limited, 2009-01-01)
CO2 sequestration in a deep saline aquifer was simulated using a compositional commercial simulator based on a single-well aquifer model, which was developed to analyze the injection and storage process of CO2 under supercritical and gaseous conditions for long periods of time. The influence of controlling parameters including vertical to horizontal permeability ratio, aquifer pressure, injection rate on the isothermal injection, and sequestration processes were investigated and the sensitivity analysis cor...
Economical Evaluation of an Oil Field Reservoir
Kök, Mustafa Verşan (Informa UK Limited, 2011-01-01)
In this study, economical evaluation of an oil field reservoir was performed using software. The software used in this study consists of different sub-programs to determine recoverable oil, recovery factor, initial and final productions, production rates, and original oil and gas in place for different types of reservoirs. Recovery efficiency was found to be 29% for water drive and 4.78% for solution gas drive reservoirs. In decline curve analysis, initial and final production rates were obtained as 40 and ...
Characterization of lignocellulose biomass and model compounds by thermogravimetry
Kök, Mustafa Verşan (Informa UK Limited, 2017-01-01)
In this research, combustion characteristics of lignocellulose biomass (hazelnut shell) and three main components (cellulose, hemicellulose, and lignin) were investigated using thermogravimetry (TGA-DTG) technique at different heating rates. The ignition, peak, burn-out temperatures, and the heat liberation of lignocellulose biomass and three main components were also measured. Two different model-free kinetic methods, known as Ozawa-Flynn-Wall (OFW) and Kissinger-Akahira-Sunose (KAS), were used in order to...
