The article presents object-based method for creating three-dimensional geological model of continental deposits (Tyumen formation case study). The input dataset of geological and geophysical information to support spatial, morphological and compositional characteristics of the facilities and principles of data implementation in the model are determined. The methodology allows to integrate in a model concept of the sedimentation and create geologically validated reservoir bodies. The results are applicable for reservoir connectivity analysis, well placement, waterflooding optimization.
