Recent events, such as the commencement of commercial development of the Novoportovskoye, Bovanenkovskoye fields in the Yamal Peninsula, the creation of infrastructure, pipeline and railway transport facilities, and the decision to build an liquified natural gas plant for the Tambey group of fields, – all of it builds a case for increasing the exploration of the resource base of the northern territories of West Siberian petroleum basin and the adjacent Kara Sea offshore. Jurassic hydrocarbon exploration leads/prospects have not been sufficiently studied and require additional exploration. The resource potential of Jurassic and Cretaceous reservoirs of South Kara region are estimated by various authors from 18,5 to 41,2 billion tons of oil equivalent. The systematization of information was executed from different sources and in the presented work was proposed the methodology for ranking the Jurassic sedimentary complexes. The ranking of selected fundamental characteristics were divided into three groups depending on their priority. This method allowed to determine the most prospective intervals of the Jurassic section for further study. The priority targets for further exploration in the Jurassic section based on the ranking results are the Middle Jurassic reservoirs of the Lower Bajocian-Upper Bathonian and Upper Aalenian-Lower Bajocian sedimentary complexes and the Upper Jurassic Callovian-Tithonian reservoirs.
