Annotation:

The authors of the article consider an integrated approach to oil deposits localization in volcanic deposits of the Pre-Jurassic complex of the Elizarovskiy depression in the Western Siberia using the example of one of the Nazym group fields. The boundaries of geological objects are determined in accordance with the geological concept, but they do not always coincide with oil deposits boundaries. To clarify the boundaries of unified hydro-dynamically connected objects within complexly built Pre-Jurassic deposits, a combination of all available geological-geophysical and field information as well as the results of oil geochemical studies is used.
