Improvement of the geological model forecast accuracy based on identification of reservoir classes and study of the same in Nh-I reservoir of Suzunkoye field

Key words: modeling, core, facies, reservoir classes, reservoir properties, permeability.

The paper presents a typification method for the reservoirs that have formed in the shallow marine shelf environment which utilizes similarity of their capillary properties. Reservoir classes were identified by well log data. Regularities of areal extension of various reservoir classes were analyzed; a method for lithological modeling is presented that takes into account the identified class. As result permeability forecast accuracy was improved this is confirmed by well testing results.
