Реферат: The invention relates to a method of establishing an enhanced oil recovery in an underground reservoir by means of a recovery system, the recovery system comprising at least one injection and production well, the injection well comprising an injection pump system, the injection pump system establishing an injection stream comprising a first injection stream and a second injection stream, wherein said injection stream comprises enzyme added at the injection well, the injection pump system establishing an injection stream through the injection well, the injection pump system being coupled with a power supply system, the production well comprising at least one fluid output, the injection well and the production well actively establishing an underground water stream, the underground water stream being established in response to pressure established by the injection pump system, the underground water stream comprising water and enzyme injected by the injection pump system, where C en
,3 is the enzyme concentration of said injection stream (a), where C en
,1 and C en
,2 are the enzyme concentration of the first and second injection stream respectively, S 1 and S 2 are flow rates of the first and second injection streams respectively.
