Abstract
A drilling assembly control system is designed to mitigate drilling vibration by detecting and classifying lateral vibrations. Vibrations are detected along a bottom hole assembly using one or more inertial measurement units, those vibration measurements are classified by lateral vibration type, and mitigating actions are determined.
