The results of regional geological exploration activity carried out according with the state programs in the period 2009-2016 in the northern part of the onshore and offshore Timan-Pechora Province made it possible to order the several tectonic elements of different ranks, establishing their hierarchical subordination and determine the characteristic features of the geological structures. A joint analysis of retrospective results and interpretation of field seismic surveys made it possible to draw up a unitary tectonic conception and trace the main tectonics elements of the Timan-Pechora Basin in its offshore part. Comprehensive geochemical studies based on core wells of the northern onshore part of the studied area made it possible to assess the potential of similar petroleum habitats with the characteristics of generation, migration and accumulation peculiarities. Tectonical, lithological and geochemical features made possible to detail the concept of geological petroleum zoning, in which two new ones - Malozemelsk-Kolguevsk and Pripaikheisk-Priyuzhnonovozemelsk units - were assigned to the rank of the regions. In the western part, promising sedimentary sequences have been identified in the basal part of the sedimentary cover. They can substantially increase hydrocarbon potential of the onshore and offshore of the Timan-Pechora Province.
