This work devoted to study the influence of water content and catalyst presence on in situ combustion processes of crude oil. The crude oils from Russia oil field were studied. Oxidation process at reservoir conditions (50 bar and 30 °C) was studied for crude oil at different water content (0, 20, 30 % by weight) and catalyst presence (Co3O4). The combustion study was investigated by accelerating rate calorimetry (ARC). Arrhenius kinetic parameters were determined for crude oils.The correlation between water conte...

In this work to study influence ratio of the components of the gas mixture of oxygen with nitrogen at thermodynamic, kinetic parameters of oxidation oil at reservoir conditions. Mixtures of oxygen with nitrogen were obtained by gravimetric method with different ratios. The oxygen content in the gas mixtures was 3, 15, 21, 40%. The main methods used accelerating rate calorimetry (ARC). Beginning of the combustion (oxidation) process depends on the oxygen content of the gas mixture. The higher oxygen content in the ...

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 °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.

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 °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 gravit...
