Nowadays, the problem of enhanced and improved oil recovery is a key one in petroleum theory and practice. Many enhanced oil recovery methods (EOR) are currently being used at local oilfields. But forcible secondary, tertiary and quaternary methods of enhanced oil recovery do not provide a scale effect. There are about 1500 active projects in the world using various EOR technologies, and their annual production build-up is estimated as 100-120 million tons. It is just about 2% of all produced oil in the world, which is equivalent to the total transporting and other losses. In terms of the final oil recovery, at many oilfields the efficiency of EOR is very low or zero. The author offers a fundamentally new scientifical-technological paradigm of exploitation, preservation, and rehabilitation of petroleum resources.
