Key words: Tyumen suite, reservoirs geometrization, estimation target, geological and statistical section, lithological heterogeneity.

Different approaches to estimation targets separation are considered on an example of Tyumen suite sediments of one of the fields of Western Siberia. It is shown, that geologically substantiated approach is also more rational in the view of reservoirs capacity conservation at oil deposits geometrization.
