... As mentioned briefly earlier, mechanisms driving HFTO were detailed by Johnson et al. (2022) who described different "Types" of HFTO dependent on the driving mechanism. HFTO with a node in the drilling motor was called Type 1, while dysfunction with the node driven by the friction at a contact...
