A physics-informed Bayesian data assimilation approach for real-time drilling tool lateral motion prediction

Frontiers in Mechanical Engineering
In this study, a Bayesian data assimilation method that fuses physics with motion sensor data is demonstrated to infer the dynamic states at points of interest on the bottomhole assembly (BHA) with proper uncertainty quantification.
