Petrofacial modeling of Priobskoye field as the basis of geological model detalization and field development optimization

Authors: M.A. Cherevko (Gazpromneft-Khantos LLC, Khanty-Mansiysk), V.V. Karanov, A.S. Bochkov, A.N. Sitnikov Klimov (Gazpromneft NTC LLC, RF, Saint-Petersburg)

Key words: petrofacial model, well logging, lithofacies, reservoir properties, hydrodynamic activity level, southern license area of Priobskoe field.

Article presents the approach to foundation of the petrofacial model of Priobskoye field. It is shown that petrofacial approach can detail geological modeling in order to increase effectiveness of field development monitoring and, in particular, in the undrilled areas. Also, presented method is able to consolidate heterogeneous and different-scale geological information and development data in order to decrease uncertainty in planning of drilling on the edges of the field.
