Paleozoic deposits, characterized by complex geological structure, require a special approach to lateral properties variation prediction. Typical correlation associations and dependencies showed limited relevance of statistical methods and low predictive potential for seismic analysis. Comparable complex structured reservoirs can be confidently predicted by traditional approach of geological similarity. Regardless of complications mentioned, Paleozoic reservoirs production is effective and close to planned values at the moment After a logical move beyond slanted well to horizontal ones, it is planned to drill multilateral wells as a next step to reduce uncertainties influence on production and to increase oil production profitability. Non-conventional informational capacity of exploitation monitoring complex for Paleozoic deposits is shown in the paper in addition. Some examples are introduced and well test data usage for porous and filtration media type selection is demonstrated aiming at hydrodinamic model enhancement.
