More than half of proven oil fields are presented by hard-to-recover oil reserves either by the quality (heavy or high viscosity oils) or location (permeability less than 0,05 um2). Hard-to-recover oil fields are characterized by low and unstable well flow rates, operation of which is hardly cost-effective in the current conditions of the Russian subsoil use. The total percentage of hard-to-recover oils in the proven reserves of Russia has exceeded 60% (in Khanty-Mansiysk District - 67%). The structure of residual oil reserves is significantly deteriorating mostly due to the fiscal extraction tax, which caused selective development of the best reserves providing 2/3 of the oil production in Russia. The tendency of increasing the percentage of hard-to-recover oils will still exist in the future. The remaining oil reserves for cost-effective development in the modern mining conditions can provide oil production, at best, until 2015. The main way of the solution of this problem is the implementation of exploration work for new fields' identification; development of previously identified undeveloped fields, development of new high technologies of oil production, integrated approach to oil refining and improvement of the regulatory framework for the oil industry.
Key words: hard-to-recover oil reserves, oil reserves structure, oil production structure, heavy oils, low permeability reservoir, development efficiency.
