Annotation:
The article presents the results of applying an integrated approach and taking into account a new conceptual understanding of the geological structure when creating a three-dimensional geological model. The work is aimed at improving the reliability of three-dimensional geological models, estimating reserves and resources, as well as optimizing the placement of prospecting-appraisal and operational wells. For the area under study, for the first time, taking into account new conceptual representation, a unified integrated 3D geological model was built that combines all deposits and promising structures. The new conceptual three-dimensional digital model of the area under study made it possible to refine the configuration of the deposits, clarify the distribution of reservoir properties over the area and section, make mathematical models more "geological", increase the reliability of reserves and resources estimates, abandon inefficient drilling and broadcast results from more studied to less studied sites.
