FIELD: oil and gas industry.
SUBSTANCE: method involves pumping to the first well in the formation of composition increasing the oil and gas recovery; besides, oil recovery increasing composition includes composition with carbon sulphur and has density that is higher than oil density; formation of mixture in the formation, which contains oil and oil recovery increasing composition; formation of gas cap of injected gas; delivery of mixture of composition and oil to the second well in the formation under action of force of gravity; and recovery of mixture of composition and oil from the second well.
EFFECT: increasing the efficiency of the method.
