Oil Outlook of Middle Jurassic Deposits at the Junction Zone of the Khantey Hemianteclise and the Upper Vasyugan Anteclise

The performed paleogeographic analysis showed that the lenses and the winding strips of sandstones formed in river channels and deltas, on lake and sea beaches and bars, forming zones of improved reservoirs. Oil accumulations in the Middle Jurassic deposits are localized, as a rule, not on local uplifts, but on their slopes and in depression zones
