High-Frequency Torsional Oscillation (HFTO) and stick slip continue to cause damage to drill bits, mud motors, rotary steerables and other downhole tools. Additionally, these dynamic events have drastic negative effects on operational efficiency, wellbore placement, and several other conditions.  Significant non-productive time can be prevented through proper understanding and mitigation of such torsional dynamics and stick slip. This session presents the latest advancement in sensor technologies, modelling and downhole tools that help us achieve this goal.
