Notwithstanding the 2 year decrease of benchmark crude oil prices, the Company demonstrates a stable growth in commercial hydrocarbon reserves. This is achieved by a constant increase of the efficiency of the development of current and start-up of new oilfields and blocks, as well as a successful implementation of the exploration program. The integration of Bashneft assets also contributed to the increase of the resource base.

In 2016 the Company followed its strategic targets and maintained its leading position by hydrocarbon reserves among public oil companies.
