The results of experiments conducted together with the analysis of the changes in the component and group composition of heavy crude oil showed that in the course of its displacement by water and surfactant composition from the model of reservoir of different permeability, 53-54% of the residual oil remains on the core material. An increase in the content of resins and asphaltenes and a sharp decrease in the content of alkanes are observed in the composition of residual oil. The content of naphthenic, aromatic hydrocarbons and heteroorganic compounds (dibenzothiophenes) is also increased.
