North Kara shelf is one of the poorly explored, but highly prospective area for hydrocarbon discoveries in Russian Arctic. Based on marine seismic and onshore geology data we recognized three main unconformities within the North Kara shelf: Late Baikalian, Caledonian and Herzinian. We believe that general structural pattern of the North Kara region was formed in Late Carboniferous-Early Permian time as a result of collision-related orogeny of Taimyr-Severnaya Zemlya domain. The re-interpretation of seismic data and subsequent basin modeling led us to conclusion that North Kara may represent mostly gas-bearing basin due to the high maturity of Lower Paleozoic source rocks.
