This paper investigates the minimum oil content necessary for elf-sustained combustion, which is introduced as a criterion for the selection of suitable reservoirs for in-situ combustion processes. Differential scanning calorimetry was used to determine the heat values of oil-limestone mixtures. The minimum temperature required for the total consumption of the fuel was obtained by thermogravimetry (TG/DTG). The minimum amount of oil necessary to sustain combustion was calculated from these two parameters and compared with the oil content of the reservoir. Reservoirs with an oil content greater than or equal to this minimum value were considered feasible. It was seen that the fields examined are generally not suitable for in-situ combustion processes.

Contribution of thermal analysis and kinetics of Siberian and Tatarstan regions crude oils for in situ combustion process Varfolomeev, Mikhail A.; Nagrimanov, Ruslan N.; Galukhin, Andrey V.; Vakhin, Alexey V.; Solomonov, Boris N.; Nurgaliev, Danis K.; Kök, Mustafa Verşan (2015-12-01) This research focused on the characterization and kinetics of Siberian and Tatarstan crude oils by gas chromatography, combustion calorimetry, and thermogravimetry (TG-DTG) techniques. Calorimetric experiments show that crude oil with higher saturate content and low resin fraction has higher heating value. TG-DTG curves indicates that the crude oils undergoes two major transitions when subjected to an oxidizing and constant rate environment known as low- and high-temperature oxidations at each heating rate ...
Comparative methods in the determination of wax content and pour points of crude oils Kök, Mustafa Verşan; Claudy, P. (2007-12-01) In this research, differential scanning calorimetry (DSC) and gas chromatography is used to determine the wax content of fourteen crude oils of different sources. Different empirical equations were applied to compare the wax content of crude oils. For the fourteen crude oil samples with the wax content ranging from 7.5 to 43.8 mass%, it was observed that the results of empirical equations were in good agreement with those determined by DSC and GC. Accordingly, a correlation between ASTM pour point and the t...
Pyrolysis and Combustion Studies of Fossil Fuels by Thermal Analysis Methods Review Kök, Mustafa Verşan (1995-02-01) Instances where differential scanning calorimetry, thermogravimetry and differential thermal analysis have been applied to study the pyrolysis and combustion behaviour of fossil fuels (peat, lignite, bituminous coals, anthracite, oil shales, crude oils, lignite-oil mixtures, etc.) are reviewed. The literature survey showed that thermal methods were important not only theoretically but also from a practical point of view.
Characterization of oil shales by high pressure DSC Kök, Mustafa Verşan; Pokol, Gy. (1999-01-01) Pressurised differential scanning calorimeter (PDSC) has been used to obtain information on the pyrolysis and combustion characteristics of oil shales. Two distinct exothermic peaks were identified in combustion experiments known as low temperature oxidation (LTO) and high temperature oxidation (HTO) reaction regions. The pyrolysis process of all studied oil shale samples showed one exothermic effect at each total pressure studied. Kinetic data were analysed by Roger & Morris and Arrhenius methods and the r...
Thermal characterization and model-free kinetics of biodiesel sample Kök, Mustafa Verşan (2015-11-01) In this study, combustion and pyrolysis behaviours of methanol route biodiesel were investigated using thermal analysis techniques known as simultaneous thermogravimetry and differential scanning calorimetry (DSC) at different heating rates. Reaction regions, peak temperatures, mass loss and heat flow rates of the biodiesel sample are determined using TG-DTG and DSC data. It was found that as the heating rate of the reactions increased, peak temperatures of the reactions shifted higher temperatures, implyin...
