Abstract

A method of estimating a stability value of a rotating downhole component includes rotating the downhole component at a varying first rotary speed, the varying first speed having a plurality of first rotary speed values, and identifying an oscillation of the downhole component. The method also includes acquiring measurement data from a sensor, the measurement data indicative of a measured parameter related to the oscillation of the downhole component at the plurality of first rotary speed values, and estimating the stability value of the rotating downhole component as a function of an operational parameter based on the acquired measurement data.
