Key words: residual oil saturation, recovery factor, oil viscosity, permeability, porosity, initial oil saturation.

The paper covers existing laboratory input data on recovery factor and residual oil saturation for reservoir B₁ of northern oil fields in Samara region and ratio given in oil and gas in-place estimation and project documentation for justification of this data. Specified generalized permeability – mobility correlation ratio of described recovery factor is given
