Drilling Practices
Transitioning from sliding to
rotating zone
During transition upwards of 30
G’s seen by the EMS
RPM variance seen from 0 to +500
RPM while moving pipe off
bottom due to static friction
RPM variance seen coming from
the high bend angle when rotating

Burst Analysis HF Data
EMS showing high torsional
vibrations, magnitudes seen in
burst data below
• Burst data shows Gyro RPM fluctuations from 0-140 RPM’s during this period
• Burst dominant frequency 0.28 hz which is the first torsional natural harmonic of
the string
• There is also a secondary frequency generated by the high bend angle of the
motor creating a second peak in the Gyro RPM signal

22. Reliability and Performance
¹Uptime is defined as the percentage of time that the Network is online and transmitting high-speed data. Uptime
% = (Possible Data Hours - Downtime)/ Possible Data Hours

28. • NOV topdrive software upgrade mitigates torsional vibration and stick
• Sends an inverse wave into the drillstring, much like noise cancelling
• Improves drilling performance by
• Improving borehole quality
• Improving RSS directional control
• Reducing torsional and coupled lateral vibrations
• Engaging cutters consistently
• Increasing founder point for higher ROP
• Increasing MTBF
• Improving MWD decoding

33. Well Control Awareness
Lost circulation events
• Along-string measurements
for improved well control
awareness
‒ Internal & annular pressure,
temperature, rotation and
vibrations
The RT annular pressure readings
were used to calculate
the relative height of the fluid
column, providing a clear
understanding of the
wellbore condition
