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.

[3][4] In January 2011, Rosneft announced that it will form a strategic alliance with BP to develop the East-Prinovozemelsky oil and gas field.

[7][8][9] The two companies agreed to invest US$3.2 billion in a joint venture to develop the three East-Prinovozemelsky blocks, as well as a field offshore of Tuapse.

[11] After Russia annexed Crimea in 2014, the US imposed sanctions that blocked the partnership, and after ExxonMobil received a brief exemption in order to safely complete drilling a well it withdrew from East-Prinovozemelsky.

[12] The request was denied in April, though the decision was not immediately fatal for the venture, as under the terms of the agreement ExxonMobil has until 2023 to begin operations in the field.
