Ikiztepe crude oil was subjected to four different steam temperatures during steam injection which was applied as an enhanced oil recovery process on a linear limestone model saturated with oil. Produced oils were characterized using density, viscosity measurements, pyrolysis experiments utilizing TGA and elemental analysis runs. Results showed that produced crude oils change in measured characteristics as compared to the original oil. These changes include an increase in H/C, and cracking activation energy, decrease in density, viscosity and amount of residue remaining after cracking (coke). Also, decrease in asphaltene amount, changes in the elemental composition of asphaltenes and increase in the cracking activation energies were observed at 225 degrees C run. These measurements show that the produced oils get lighter and differ compositionally from the original oil as steam temperature increases. Decrease in elemental sulphur amount is one of the major changes when environmental considerations are concerned. Residual oil left in the limestone pack on the other hand shows an increase in the low temperature oxidation (LTO), fuel deposition (FD) and high temperature oxidation (HTO) activation energies as determined from TGA combustion experiments on the samples taken from the pack after steam injection experiments.

Laboratory steam injection applications for oil shale fields of Turkey Kök, Mustafa Verşan; Bagci, S. (Estonian Academy Publishers, 2008-01-01) In this study, applicability of oil production from oil shales by steam recovery in a three-dimensional (3-D) reservoir model was investigated. Four different oil shale samples from several fields (Seyitomer, Beypazan, Himmetoglu and Hatildag) were used. 3-D steam injection experiments showed that steam injection was insufficient to drive oil production for the oil shale samples studied, and it was concluded that the steam injection process is not feasible in these oil shale fields.
Application of different EOR techniques for the energy and recovery of Ashal'cha oil field Kök, Mustafa Verşan; Nurgaliev, Danis K. (Informa UK Limited, 2018-01-01) In this research, utilizing the reservoir and produced oil data, different enhanced oil recovery (EOR) techniques known as in-situ combustion, CO2 flooding, and steam flooding were applied for Ashal'cha oil field in Republic of Tatarstan, Russia. For this purpose, In-Situ Combustion Predictive Model (ICPM), CO2 Miscible Flood Predictive Model (CO2PM) and Steam-flood Predictive Model (SFPM) are used. In addition to oil recovery, economic analysis of the discussed EOR applications was also conducted. By using...
Application of predictive Enhanced Oil Recovery models on a very heavy oil field Kök, Mustafa Verşan; Akın, Serhat (Informa UK Limited, 2001-12-01) In this study, several predictive enhanced oil recovery (EOR) techniques are used to evaluate potential thermal oil recovery techniques that could be applied on a very heavy oil (10-12°API) field located in Southeast Turkey. Two of the EOR techniques were found to be applicable after the screening process: in situ combustion and steam injection. Sensitivity of the processes to several operating parameters, such as steam injection rate, air injection rate, and steam quality, were established. It was observed...
3-d model studies of alkaline flooding using horizontal wells Bağcı, Ali Suat (Informa UK Limited, 2004-07-02) In this study, the effect of sodium hydroxide (NaOH) solution for the improved oil recovery of Garzan (26degreesAP1) crude oil was investigated using two different laboratory models. The effect of injection rate on oil recovery was investigated using a one-dimensional unconsolidated limestone reservoir model. The effect of horizontal and vertical well configurations on oil recovery was also studied using a 3-D physical model and various well configurations. As previously studied, the interfacial tension mea...
INCIDENTAL RELEASE OF BITUMEN DURING OIL SHALE GRINDING AND IMPACTS ON OIL SHALE BENEFICIATION Altun, Naci Emre (Estonian Academy Publishers, 2009-01-01) The particle surface characteristics of oil shale and the changes in these characteristics with increasing fineness were determined. FTIR and electro-kinetic studies showed that the surfaces of oil shale particle were controlled by oxygen-rich polar groups. FTIR and XPS studies showed that with increasing fineness the polar oxides decreased and organic surface groups increased at grind sizes finer than 100 microns. Flotation was used to view the impact of the changes in surface characteristics on oil shale ...
