Annotation:

When determining the position of the oil-water contact (OWC) level, in some cases when building a geological model, the OWC surface has a regional slope. This problem was identified as part of the work on the calculation of oil and dissolved gas reserves of YuV₁¹ formation of Nong-Yegansky oilfield, where the difference in the position of the OWC surface is more than 40 m. The article, based on paleotectonic analysis, considers the criteria of selecting the data for the deposit reconstruction in different periods of a geological period.
