The article is devoted to the problem of identifying deposits in Western Siberia completely undersaturated with oil. At a primary test of such reservoirs from their roofing part joint inflows of oil with water are always received. The analysis of research results shows that the determination of the deposit area depends on a large extent on the reliability of the installed fluid contacts in the section of each well. We give examples of discrepancies between well testing interpretation and well test results. There are also examples of the groundlessness of the separation of a single geological body into several counting objects. The size of the shift of oil-water contact is determined by the action of capillary forces.
