FIELD: oil-and-gas production.
SUBSTANCE: proposed method comprises the following steps: a) forcing flooding fluid into deposit, and b) extracting oil from borehole in location other than that of forcing flooding liquid. Flooding liquid includes water and some amount of one or more specified viscoelastic nonpolymeric surfactants sufficient for interfacial surface tension approximating to 1 mNm or smaller, and viscosity of 10 sP or larger. Proposed invention is developed in dependent claims.
EFFECT: higher efficiency of tertiary oil extraction.
