FIELD: gas and oil production.
SUBSTANCE: procedure consists in injection of composition for increased oil recovery into first well in pay; in creation of forced flow of oil and/or gas in direction of second well in pay; in recovery of oil and/or gas from second well; in injection of agent facilitating increased oil recovery in direction of first well in pay; and in extraction of composition for increased oil recovery from first well. Also composition for increased oil recovery has density higher, than density of agent facilitating extraction of fluid medium.
EFFECT: increased efficiency of procedure due to increased oil yield of pay.
