In this research, four different crude oils from Tatarstan oil fields with wide range of API gravities (from 16.6 to 32.5 degrees API) were used for hydrogen and carbon nuclear magnetic resonance spectroscopy (H NMR and C NMR) determinations. The hydrogen and carbon aromaticity factors were calculated by using the results of H NMR and C NMR spectroscopy results. The results show that the aromaticity factors were high for heavy crude oils. For predicting SARA fractions, the correlations were developed as a function of aromaticity factors. The developed correlations showed high accuracy for predicting SARA fractions for four crude oils.

The effect of water on combustion behavior of crude oils
Kök, Mustafa Verşan; Nurgaliev, Danis K. (Elsevier BV, 2020-03-01)
The ramped temperature oxidation experiments were performed on heavy and light crude oil samples using the TGA and DSC instruments. The crude oils were mixed with different weight percentages (10%, 20%, and 30%) of water, as a result of which six different water-oil mixtures were prepared. The samples were heated up to 800 degrees C with three heating rates 20, 25, 30 degrees C/min. Two reaction regions, particularly the low temperature oxidation (LTO) and high temperature oxidation (HTO), were identified i...
Characterization and kinetics of light crude oil combustion in the presence of metallic salts
Kök, Mustafa Verşan (American Chemical Society (ACS), 2004-05-01)
In this research, a reaction cell, thermogravimetry (TG), and differential thermal analysis (DTA) were used to characterize the light crude oil combustion and kinetics in the presence of copper(I) chloride (CuCl) and magnesium chloride (MgCl2·6H2O). In TG-DTA experiments with magnesium chloride, three reaction regions were identified, known as distillation, low-temperature oxidation (LTO), and high-temperature oxidation (HTO). In the case of copper(I) chloride, two main transitional stages are observed with...
Characterization of medium and heavy crude oils using thermal analysis techniques
Kök, Mustafa Verşan (Elsevier BV, 2011-05-01)
This study focused on the characterization of heavy and medium grade crude oils in limestone matrix using differential scanning calorimeter (DSC) and thermogravimetry (TG-DTG). DSC and TG-DTG curves produced for two different crude oils + limestone mixtures indicate that the crude oil undergoes two major transitions when subjected to an oxidizing and constant rate environment known as low- and high-temperature oxidation. Kinetic analysis in the low- and high-temperature oxidation regions were performed usin...
Estimation of permeability and rock mechanical properties of limestone reservoir rocks under stress conditions by strain gauge
Iscan, A. G.; Kök, Mustafa Verşan; Bagci, A. S. (Elsevier BV, 2006-08-01)
Petroleum engineering reservoir parameter calculations are generally performed in the absence of the overburden pressure effect. This leads to serious errors in further development of a hydrocarbon-bearing reservoir. Thus, measurements under stress conditions become important vitally. The objective is to correlate the overburden pressure and the permeability to see the overburden pressure effects on the permeability of Turkish southeastern limestone reservoir rock samples. Stress was applied to four represe...
Effect of inlet pressure on crude oil combustion -laboratory approach-
Kök, Mustafa Verşan; Nurgaliev, Danis K. (Elsevier BV, 2021-03-01)
In this research, the effect of inlet pressure on combustion behavior of medium and light crude oils was analyzed with TGA and DSC experiments. The ramped temperature combustion experiments were performed at constant heating rates under air atmosphere. TGA curves revealed three main reaction regions known as low temperature oxidation (LTO), fuel deposition (FD), and high temperature oxidation (HTO). In DSC curves, at the early stage of the heating, distillation region was also observed in addition to LTO an...
