Gazprom Neft Messoyakhaneftegas, an equally owned joint venture with TNK-BP, holds the licenses for both blocks with Gazprom Neft as operator. The recoverable C1+C2 reserves of both blocks total 620 million tonnes of primarily heavy oil. The fields were discovered in the 1980s and are the most northern-located onshore Russian fields. The Messoyakha oil and gas fields are located on the Gydan Peninsula in the Tazovsky District of the Yamalo-Nenets Autonomous Area - an Arctic climate zone with undeveloped infrastructure. By 2020 the Messoyakha fields are expected to be producing 8 mln tonnes per year with the first million produced by 2016.
