Peculiarities of the formation of Upper Jurassic deposits on the example of the object US1

In this work, we analyzed the stock materials on the CS field to obtain an information base to characterize the geological structure of the Vasyugan formation oil deposit (object US1). According to GIS data, the section types of the formation of US1, which determine the distribution of initial oil reserves and the pattern of low rates of oil reserves in the localized dead-end and stagnant zones are highlighted. The characteristics of the displacement of the main reservoirs of the object US1 are presented. The most favorable groups of reservoirs by type of reservoirs (monolithic and irregularly layered) are identified.
