Abstract: A drilling control system may receive a target toolface and rate of penetration (ROP) and receive a first toolface and ROP. The system may calculate a toolface error based at least in part on a difference between the target and first toolface and calculate a ROP error based at least in part on a difference between the target and first ROP. The system may determine an additional reactive torque for correcting ROP error, generate one or more spindle changes based at least in part on toolface error and additional reactive torque, and generate one or more block speed changes based at least in part on ROP error. The system may send one or more control signals to one or more control systems coupled to the drilling rig to implement and drill in accordance with the one or more spindle changes and the one or more block speed changes.

Abstract: A drilling control system may access a drilling plan for a borehole comprising one or more of planned path for the borehole, drill string information, mud properties, drill bit properties, formation properties, and drill rig properties. The system may receive a plurality of operating parameters from a rig for the borehole including one or more of an observed toolface, a spindle setting, a rate of penetration, a differential pressure, and a weight-on-bit. The system may receive one or more propagation functions for the borehole determined by a model of the drill string. The system may determine one or more spindle changes or block speed changes based at least in part on the propagation functions and the plurality of operating parameters. The system may generate one or more predicted drill properties from a simulator using the one or more spindle changes or the one or more block speed changes.
