The paper assesses the nature and level of vibration while drilling wells in the Kovykta gas condensate field using telemetry systems with a hydraulic communication channel. The presence of vibrations during drilling allows it to carry out its main task – controlled destruction of the rock. Nevertheless, upon reaching certain parameters of direction, frequency, shock loads, their result may cause worsening of the facility construction time as well as destruction of BHA elements. The results of the study can be useful when analyzing techniques of improving the technology of drilling directional wells with horizontal completion, with the presence of telesystems with various communication channels as part of the BHA. Optimization of the technology allows reducing the time of wells construction, decreasing the risk of accidents, and increasing the operational life-time of all BHA elements.
