Tatarstan is one of the biggest oil producers in Russia - with big ambitions.
The state-owned oil company Tatneft is building the largest refinery complex in the whole country, part of a strategy to enlarge the domestic petrochemical industry.
At the same time, the republic is also facing some serious challenges, as its main oil field, the giant Romashkino field, is now well past its peak, and extracting oil is becoming more and more difficult.
