The Rosneft Commission: What We Should Be Looking For
MOST AMERICANS have never heard of it, but Rosneft is one of the worlds largest publicly traded oil companies, with revenues of $91 billion in 2015 ranking 23rd overall among oil and gas concerns. Its majority owner is the Government of Russiain other words, Vladimir Putin and his circle of oligarchs, including Rosneft CEO/Putin BFF Igor Sechin.
In 2012, Rosneft entered into a $500 billion joint venture with ExxonMobil, which at the time was run by current Secretary of State Rex Tillerson; it was this mammoth joint venture, apparently, that inspired Putin to award Tillerson the Medal of Friendship in 2013. The oil reserves in the Arctic, the reason for the venture, are estimated to contain 85 billion barrels. At a conservative price of $50 a barrel, that amounts to a staggering $4.25 trillion in potential gross revenue.
