The Tyumen Formation - Russia's next million b/d play?
The Tyumen formation's importance to Russia is growing rapidly. Between 2009-14 production more than doubled to over 400,000 b/d. With sanctions impacting the offshore Arctic and shale oil projects, the Tyumen has emerged as a way of maintaining West Siberian production - which accounts for 65% of Russia's oil output. The Tyumen is being developed as a secondary or tertiary reservoir under brownfields as well as at greenfields where it is the major reservoir - gaining significant tax breaks.
