East-Prinovozemelsky field East-Prinovozemelsky field The East-Prinovozemelsky field (also referred as Vostochno-Prinovozemelskoye structure – meaning: East of Novaya Zemlya structure) is a gigantic undeveloped Arctic oil and gas field located in the South Kara basin of the continental shelf of Russia, in the South Kara Sea between the Yamal Peninsula and Novaya Zemlya island. It is the continuation of the continental West Siberian hydrocarbon province. The field is divided into three license blocks: EPNZ-1, EPNZ2, and ENPZ-3. In October 2010, licenses for all three blocks were awarded to Russian oil company Rosneft. In January 2011, Rosneft announced that it will form a strategic
Baltica belt of the Timanide orogeny and overlain by Mesoproterozoic sediments. The margin became a passive margin facing an Ural Ocean in the Cambrian-Ordovician. The eastern margin stretches south through the Ural Mountains from the northern end of the Novaya Zemlya archipelago. The margin follows the bent shape of Novaya Zemlya which was caused in the Late Permian by the Siberian Traps. It is clear from Baltic endemic fossils in Novaya Zemlya that the islands have been part of Baltica since Early Palaeozoic, whereas the Taymyr Peninsula farther east was part of the passive margin of Siberia in the Early Palaeozoic.
