ABSTRACT
This article describes the method of multivariate calculation of geological uncertainties and the first stage of the geological model construction - well correlation of the pashiysky horizon of Novosergievsky and Perevolotsky districts of the Orenburg region in the domestic tNavigator software product of RockFlowDynamics. This technique allows to construct geological models of the pashiysky horizon on variants P10 (optimistic), P50 (realistic), P90 (pessimistic), thereby to estimate risks and to carry out quality control of geological model. This method is used to construct structural maps of the roof and bottom of the pashiysky horizon.
