Abstract: Currently, the volume of difficult oil in the world is increase and amasses close to 70%. Electric submersible pumps (ESPs) and jack pumps (SRP) used ever more 80% of the wells. Mechanical method of production is not always effective due to the low coefficient of efficiency pump units operating in marginal wells. There is a limit for well production rate below which produce oil is technically impossible or economically unprofitable. Many wells, currently stopped oil production due to unprofitability of oil wells with hard to recover reserves. It leads to their conservation or liquidation. The number of such wells is of these wells is about 25000-30 000. Pressure communication suffers from lack of quality in a "well-formation". It is caused by technological problems in the construction of wells, particularly in the productive intervals. It leads to excessive pressure in the reservoir, and then plugging reservoir mud filtrate or the cement slurry reaches a depth of several meters.
