This work devoted to study in situ combustion processes of different crude oil. The crude oils from different field of Russian Federation were selected. Oxidation process in reservoir conditions (50 bar and 50 В°C) were studied for all crude oils. The combustion study was investigated by accelerating rate calorimetry (ARC). This method is most suitable for studying the processes of oil oxidation in reservoir conditions. Arrhenius kinetic parameters were determined for crude oils. The correlations between API gravi...

This work devoted to study in situ combustion processes of crude oil at different pressures. The crude oils from Russian Federation were selected field. Oxidation process in reservoir conditions (50.7, 83.8, 101.2, 125.5 bars and 50 В°C) was studied for crude oil. The combustion study was investigated by accelerating rate calorimetry (ARC). Arrhenius kinetic parameters were determined for crude oils. The correlation between reaction duration and initial pressure was found.
