FIELD: oil and gas production.
SUBSTANCE: invention provides oil production composition serving to limit water inflow into producing wells and thereby to increasing recovery of oil. Composition is made up of "Neftenol NZb", 10-15%, synthetic latex, 2-5%, and liquid hydrocarbon.
EFFECT: increased efficiency of production of oil for watered formations in late development stage due to increased stability of composition, increased oil-driving property, and expanded coverage of formation.
