Abstract

The paper considers methodological approaches to modeling of reservoirs with continuous genesis. The study reveals that construction of the most reliable reservoir geological model depends directly on the amount, quality and completeness of input data. The example of one of the fields in the Nefteyugansk region is presented to demonstrate the influence of a priori data associated with vertical and horizontal distribution of productive reservoirs in the interwell space on oil reserves estimates.
