Maintaining a high level of production volume means the maximum use of the opportunities of each well. The application of a number of ways to intensify well productivity, such as hydraulic fracturing, acid treatment, heat treatment, etc. is not always possible due to a number of geological and technological reasons. In addition, each of these methods has a negative component effect on the reservoir properties. The effectiveness of these methods, the impact on the bottom zone (producing zone) is often limited by the lack of reliable hydrodynamic connection between wells producing formation, which may be caused by deterioration of reservoir properties over time, the lack rock permeability, reservoir heterogeneity, insufficient length of perforations, etc. [1].

The new technology is designed to increase the perforation production flow rates and increase injection capacity of injection wells (by increasing filtration area producing zone), reduce water cut (by reducing the drawdown), as well as improving the turnaround time for well operation (by increasing the hydraulic perfection of producing zone) [2].

The technology involves the removal of the casing of the first stage of research and development project (hereinafter – drilling through the casing with change bit without lifting oriented capture and anchors for drilling in rock shown in Figure 2. The extension of the main trunk, injecting insulating special gelling agent, the creation of cement plug, drilling out its auxiliary barrel, drilling super long channels according to the predicted trajectory in one run [2, 3, 6].
