CJSC Novinka, a member of the FID Group, has developed a new directional drilling system SNB89-76M with an electric communication channel. It is designed for directional drilling of all types of wells as a part of coiled tubing units or other drilling complexes that provide a cable communication channel between the bottomhole assembly and the ground installation. Field tests of the system have been successfully performed in the well of Kotelnikovskoye field of the Republican Unitary Enterprise “Production Association “Belorusneft”. Drilling operations were performed in clay-bearing and carbonate formations with the help of coiled tubing unit M30 manufactured by NOV Fidmash (injector pull capacity is 77,000 lbs, coiled tubing length is 12,150 ft and OD is 2"). Completed field tests showed the reliability of functioning and control stability of all elements of the directional drilling system, as well as its compliance with technical parameters.
