In this research, kinetics of four crude oils from different origins are determined by iso-conversional methods using thermogravimetry data (TGA-DTG). The experiments were performed at three different heating rates (5-10-15 K/min) between 300 and 1200 K. Thermal characteristics of the crude oil samples such as, reaction intervals and corresponding peak and burn-out temperatures are also determined. Three different iso-conversional methods, known as Starink, Kissinger and Friedman are used in order to determine the activation energy values of the crude oil samples studied that represents the novelty of the research. Activation energy values of the crude oil samples are varied between 50 and 102 kJ/mol and 69-132 kJ/mol in low temperature oxidation region and high temperature oxidation region, respectively.

Thermal characterization of crude oils by pressurized differential scanning calorimeter (PDSC)
Kök, Mustafa Verşan; Nurgaliev, Danis K. (Elsevier BV, 2019-06-01)
In this research, pressurized differential scanning calorimeter (PDSC) were used to estimate the thermal and kinetic behaviour of two different crude oils from Tatarstan oil fields under three different pressures (100, 600, 2000 kPa) at a constant heating rate (10 degrees C/min). The heat flow curves of both crude oils indicated two reaction regions known as low temperature oxidation (LTO) and high temperature oxidation (HTO). The reaction intervals were shifted to lower temperature regions with the increas...
Sensitivity Analysis of Major Drilling Parameters on Cuttings Transport during Drilling Highly-inclined Wells
Ozbayoglu, E. M.; Miska, S. Z.; Takach, N.; Reed, T. (Informa UK Limited, 2009-01-01)
In this study, a layered cuttings transport model is developed for high-angle and horizontal wells, which can be used for incompressible non-Newtonian fluids as well as compressible non-Newtonian fluids (i.e., foams). The effects of major drilling parameters, such as flow rate, rate of penetration, fluid density, viscosity, gas ratio, cuttings size, cuttings density, wellbore inclination and eccentricity of the drillsting on cuttings transport efficiency are analyzed. The major findings from this study are,...
Combustion kinetics of oil shales by reaction cell experiments
Kök, Mustafa Verşan; Bagci, S. (Estonian Academy Publishers, 2008-01-01)
In this study, kinetics parameters of combustion reaction of Seyitomer and Beypazari oil shales were determined using Weijdema's model of reaction kinetics. The analysis of reaction kinetics experiments showed two different reaction regions at combustion of Beypazari oil shale sample. Only one reaction region was observed at combustion of Seyitomer oil shale. CO2/CO ratios increased gradually at low and medium temperatures and stabilized at high temperatures, especially after complete combustion. A decrease...
Multiscale pore structure characterization of middle east carbonates
Gundogar, A. S.; Ross, C. M.; Akın, Serhat; Kovscek, A. R. (Elsevier BV, 2016-10-01)
This paper focuses on the measurement of pore-scale geometrical and topological properties of heterogeneous Middle East carbonates using scanning electron microscopy (SEM), image analysis, and mercury porosimetry. Quantitative pore network descriptors including porosity, pore body and throat sizes, coordination number (number of throats per pore), shape factor (pore area to perimeter ratio), aspect ratio (pore body to throat size ratio), and their distributions are determined from SEM-based images of thin s...
Oxidation Behavior of Light Crude Oil and Its SARA Fractions Characterized by TG and DSC Techniques: Differences and Connections
Yuan, Chengdong; Varfolomeev, Mikhail A.; Emelianov, Dmitrii A.; Eskin, Aleksey A.; Nagrimanov, Ruslan N.; Kök, Mustafa Verşan; Afanasiev, Igor S.; Fedorchenko, Gennadii D.; Kopylova, Elena V. (American Chemical Society (ACS), 2018-01-01)
This research is intended to reveal the difference and connection of oxidation behavior between crude oil and its SARA fractions. Thermogravimetry (TG) and differential scanning calorimetry (DSC) techniques were used to characterize oxidation behavior. The results showed that the oxidation behavior of individual SARA components exhibited an obvious difference. Saturates showed a weak high-temperature oxidation (HTO) region. Asphaltenes generated more heat in HTO than in the low-temperature oxidation (LTO) r...
