FIELD: oil and gas industry.
SUBSTANCE: system for extraction of oil and/or gas from underground formation of deposit includes the first set of wells located above the formation, the second set of wells located above the formation. The first set of wells is equipped with means for injection of mixing compound to the formation to increase oil recovery of the formation. The second set of wells is provided with means for extraction of oil and/or gas from formation during the first period of time. The second set of wells is equipped with means for injection of cleaning agent to the formation, while the first set of wells is provided with means for extraction of mixing compound to increase oil recovery during the second period of time.
EFFECT: higher efficiency of the method and reliability of the system.
