Based on the analysis of modern publications, a number of problems that arise when drilling horizontal wells have been disclosed. The conclusion about the need to justify the choice of perfect technical means and advanced technologies for drilling horizontal wells has been made. The operation principle of rotary-controlled systems complete with telemetry systems for successful horizontal well development has been highlighted. The main characteristics of rotary-controlled systems that characterize their work as a whole have been presented. The main parameters that most significantly characterize the operation of such systems have been formed. A morphological analysis of rotary-controlled systems has been carried out, and the universal ones have been selected for operation in different geological and technical conditions. A number of methods for reducing the friction of the drill string against the walls of the wellbore have been considered, and the efficiency of the reactive-acoustic equipment and technology for drilling horizontal wells has been substantiated. The main characteristics of drilling fluids, universal and solving a number of problems when drilling horizontal wells, have been considered. An analysis of the designs of drilling flights for drilling highly deviated and horizontal wells has been carried out, and a rock-cutting tool from Nov Downhole has been recommended. The conceptual development of the Schlumberger company, called autonomous directional drilling, has been considered in detail
