The issues of assessment of nature of reservoir saturation and identifying water encroachment zones within formations of the production wells were considered. Criteria which allow classifying reservoirs according to nature of their saturation were given. Assessment of reliability of resistivity of permeable interlayers in heterogeneous reservoirs containing dense carbonized intercalation was carried out. If this interlayeris not distinguished on the optimal probe of apparent resistivity, then the resistivity of permeable accumulations in a heterogeneous reservoir is roughly equivalent to the average indication of the optimal probe.
