Abstract
Systems and methods for directional drilling are described. The system includes one or more controllers and is configured to receive data from a plurality of downhole sensors, provide operational control signals, determine a relationship between different parameters, receive current data including at least one of current differential pressure (DP), weight-on-bit (WOB), or rotations per minute (RPM) of a drill bit, and estimate at least one of current toolface orientation or current shock and vibration of the drill bit using the current data and the determined relationship. The system is further configured to provide operational control signals that may adjust the current toolface orientation to a desired toolface orientation. Current WOB and/or current RPM are adjusted to minimize current shock and vibration of a portion of a bottom hole assembly (BHA).
