Abstract
An approach to estimation of physical properties of reservoirs based on lithofacies conditions of their formation has been discussed. The Jurassic sediments of the East Surgut oil deposit are distinguished by diversity of facies varieties and thus are appropriate for illustrating the approach. It is reasonable to calculate the reservoir porosity using separate facies for each stratum. A facies-based technique is proposed to dismember the strata with the use of author's cross plots for estimating the porosity of Jurassic deposits of the Surgut arch.
