Paleo-environment and Regional Oil Prospectivity of Triassic Deposits in the Barents Sea

arly, Middle and Late Triassic depositions are reconstructed and the areas of the possible Triassic source rock development are mapped. It is marked that these areas had been forming during the entire Triassic in the deepest parts of the East Barents Trough where its sections is most complete. New zones of litological and structure - litological traps development within south-western and central part of the South Barents basin are outlined. The research results indicate rather high probability of new oil discoveries in Triassic deposits of the Barents Sea, particularly within board and uplifted zones of deep trough. Oil pool may be confined to sandy, siltstone – sandy or sandy – pebble reservoirs in litological and structure - litological traps.
