Zusammenfassung:Disclosed is a method of measuring stick slip in an earth drilling system, and a system for performing same. The method includes positioning an accelerometer in a downhole component of a drill string, the accelerometer being radially offset from a centerline of the downhole component, obtaining acceleration data for the drill string during drilling operations using the accelerometer and determining if the drill string has experienced stick slip based upon mean acceleration values obtained by analyzing the acceleration data obtained using the accelerometer.
