The estimation of the share of hard-to-extract oil reserves in the deposits of Russia varies by different sources, in a fairly wide range (from 30 to 70 %). Due to the absence of a common approach to their definition, the variety of parameters used to estimate this share and fundamentally different conditions for the development of the groups of reserves classified as hard-to-extract become challanging. A significant share of the proven oil reserves of Russian oil fields - about 34 % (6.3 million tons) - belongs to heavy (oil density more than 0.871 g/cm3) and super-heavy (oil density more than 0.895 g/cm3). In general, the share of high-viscosity and super-highviscosity oils is about 13% (2.4 million tons). The largest share refers to the deposits of three districts. In lowpermeable collectors (permeability less than 0.05 μm2), huge reserves are concentrated – 8.2 million tons or 44.6 % of all oil. Comparison of oil extraction and reserves structure indicates a good correlation for oil extraction from low-permeable collectors in 41.8 % with reserves percentage in 44.6 % as well as a relatively good correlation in super-heavy oil in 13.4% with reserves percentage in 18 % and low rates for super-high-viscosity oil in 1.7% with reserves perecentage in 6 %. Significant proven reserves of high-viscosity oil in Russia indicate the possibility of increasing production with the introduction of modern, existing and proven, technologies under appropriate economic conditions. Full-scale involvement in the development of only the largest deposits of high-viscosity oil would allow the Russian Federation to produce at least 25-30 million tons in the medium term.
