In September 2020, drilling of the second horizontal section with a length of 1500.0 m was completed at the Sredne-Nazymskoye field using MWD LHE630N telemetry equipment.

The horizontal section was drilled for 10 days. In the process of drilling, the zenith angle was transmitted in dynamics from the MWD downhole equipment to the surface. The dynamic zenith angle provided additional information to control the wellbore trajectory within a given drilling corridor. The uninterrupted operation of the MWD complex was ensured by two battery modules, which made it possible to drill a horizontal section in one run (without an intermediate lift to replace batteries).
