The developed modular MWD-based logging while drilling systems ZTK-42EM and ZTK-42KK allow for not only well drilling within the designed wellbore path, but also adjusting the wellbore for its optimal placement in the most productive part of the bed. Logging data visualization systems and monitoring services help to promptly respond to and control the drilling process.
