The Callovian and Upper Jurassic petroleum-promising deposits of northern West Siberia have a polyfacies composition. The correlation between these deposits, including producing beds, is still much disputed. The article reports correlations between these beds at the level of zonal cyclites. More reliable age analogs of the Bazhenov Formation have been recognized in eastern-type sections. The diachronous nature of the upper boundary of the Vasyugan Formation and the clinoform structure of the Upper Jurassic deposits are confirmed. It is shown that the Tochino Formation and the Lower Sigovsk Subformation of the Turukhan-Elogui district are similar in composition and structure to the Lower and Upper Vasyugan Subformations, respectively. The stratigraphic position, volumes, and areal occurrences of main producing and promising sand beds J11−J14 and SG1–SG4 are refined.
