The North Kara Basin has a supposedly thick Middle Ordovician to Early Devonian carbonate platform with diverse facies environments. Source rocks may be contained in Ordovician, Silurian and Devonian sediments. The North Kara Basin experienced compression at about the Devonian-Carboniferous boundary. The formation of most inverse structures is associated with this event. As early as at the regional phase of investigation, a significant number of promising features has been revealed in deposits of all Palaeozoic systems, with both anticlinal and stratigraphic and lithological potential traps. Presently, the northern part of the Kara Sea remains one of the least studied regions of the Barents-Kara Shelf.
