Arktikgaz

Arktikgaz, together with Urengoil and Neftegaztekhnologiya was founded as Severneftegaz which was one of the first independent oil and gas companies in Russia. On 11 August 1998, the American-based Benton Oil and Gas Company acquired a 40% share in Severneftegaz and increased its stake afterwards up to 68%. Other shareholders of this time were Gazprom, Urengoyneftegazgeologiya and Logovaz.

In 2002, in a series of transactions, 100% of Arktikgaz shares were acquired by Yukos. On 4 April 2007, shares in Arktikgaz together with other Yukos-owned companies Urengoil and Neftegaztekhnologiya were acquired by EniNeftegaz, a joint venture of Italian companies Eni (60%) and Enel (40%) created to purchase the former Yukos assets.[1] Later Enineftegaz was renamed SeverEnergia. On 23 September 2009, 51% of SeverEnergia was acquired by Gazprom for US$1.5 billion.[2] In November 2010, Gazprom sold is stake in SeverEnergia to Yamal Development LLC (Russian: Yamal razvitiye), an equally owned joint venture of Gazprom Neft and Novatek.[3][4]

In September 2013, Enel sold its 19.6% stake (owned through a joint venture with Eni, Artic Russia B.V.) to Rosneft for $1.8 billion.[5] In November 2013 Gazprom Neft bought Eni's stake in SeverEnergia for $2.94 billion.[5] Later that year Novatek acquired the Rosneft's stake as a result of the assets swap.[6] In 2018, Gazprom Neft and Novatek merged SeverEnergia and Yamal Development into Artikgaz and equalized their shares in the company.[7]

SeverEnergia produces the natural gas, condensate, and oil in the Samburg, Yevo-Yakha, Yaro-Yakha, and Severo-Chaselsky licences within and adjacent to the Urengoy gas field.[8] Produced natural gas is purchased by Gazprom.[8][9]
