High-Frequency-Torsional Oscillations (HFTO) generate dynamic loads that can damage drilling tools, resulting in, for example cracks, twist-offs or broken electronics. They are triggered by the interaction of bits and rocks and force operators to red

The industry trend to drill wells faster and with greater precision in hard, dense, difficult to drill formations results in challenging drilling dynamics conditions. In particular, high-frequency torsional oscillations (HFTO) occur in such drilling
