Abstract
A HFTO mitigation system may receive torque measurements and vibration measurements for a drill string. A HFTO mitigation system may generate a plurality of frequency modes for the drill string using a physical model of the drill string. A HFTO mitigation system may apply an HFTO model to the torque measurements and the vibration measurements to identify an HFTO mode. A HFTO mitigation system may, when the HFTO mode correlates with one of the plurality of frequency modes, adjust at least one of a weight on bit or a rotational rate of the drill string.
