Mikhail Gutseriev and his partners were the initial founders and owners of RussNeft. As of March 2009 the actual control over RussNeft was taken by to the companies Bazoviy Element, the holding owned by Oleg Deripaska, who paid 3 bn for the company, though formally the deal was not closed because it was not approved by the Federal Antimonopoly Service. Glencore also had an option for purchasing a blocking stake in RussNeft.
