In-situ combustion (ISC) is considered one of the most effective method to increase oil recovery from heavy oil and bitumen. Oxygen of injected air reacts with the heavy crude oil components, forming a hot zone, in which the oxidation and cracking of heavy fractions occur. It is known that catalysts of various types can significantly improve the processes of oil upgrading and increase the efficiency of thermal tertiary methods of oil production. This work devoted to study the influence of mixed oxide catalyst pres...

In-situ combustion is considered as one of the most effective ways to enhance recovery of heavy crude oils and bitumens. The oxygen from injected air reacts with the heavy components of the crude oil, forming a hot zone in which the cracking and oxidation of the heavy fractions occurs. It is noted that the combustion process essentially depends on the pressure and the nature of the crude oil. Thus detailed study on the effect of the gas phase composition on the processes of crude oil oxidation seems to be relevant...

It is noted that the combustion process essentially depends on the pressure and the nature of the crude oil. The effect of the oxygen content in the gas mixture on the combustion front propagation of heavy crude oils is shown. When ...
