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. In November 2013 Gazprom Neft bought Eni's stake in SeverEnergia for $2.94 billion. Later that year Novatek acquired the Rosneft's stake as a result of the assets swap. In 2018, Gazprom Neft and Novatek merged SeverEnergia and Yamal Development into Artikgaz and equalized their shares in the company.
