Authors: G.P. Khizhniak, A.V. Raspopov (PermNIPIneft Branch of LUKOIL–Engineering Ltd in Perm), A.A. Efimov (Perm State National Research Polytechnical University)
The results of laboratory investigations of oil displacement by fresh and reservoir waters on core are presented in the paper. Coefficients of oil displacement by fresh and reservoir waters are compared. Parameter including collector permeability, oil and water viscosity, which permits to reveal total dependence for both types of water, was proposed.
