With respect to the central and southern regions of the Siberian Platform, the authors for the first time briefly discuss the results of integrated studies of architecture, composition, assessment of reservoir quality and petroleum potential of all the carbonate formations identified within the best investigated subsalt carbonate (Б12–Б10, Б5, Б4–3 beds) and less investigated halogenic-carbonate (Б1, А6–А1 beds) sequences. The authors show that, despite their complicated structure, low efficiency of exploration target determination (since they are mainly of non-anticlinal type), as well as outdated technologies of carbonate formations drilling-in and testing, they have rather high petroleum potential. Commercial oil and gas occurrence was revealed in all the formations. A total of 90 hydrocarbon accumulations have been discovered in these sediments situated in 42 fields. The priority targets for preparing oil and gas reserves were predicted. Using modern geological exploration techniques in the sequences under consideration can significantly increase the amount of hydrocarbon production up to the volumes typical of the terrigenous Vendian sequence within the region under consideration.
