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

While drilling a wellbore, several types of vibrations exist that can lead to inefficient drilling. These are commonly subdivided into lateral, torsional, and axial vibrations. Especially in hard and dense formations, high-frequency torsional oscilla
