Abstract: In a drilling system, a control system coupled to a drilling rig controls a bottom hole assembly (BHA) to drill a borehole through a geological formation along a drilling path. The control system determines a present position of the BHA and calculates a toolface vector to create a convergence path from the present position of the BHA to a desired target path. The control system also receives geological information and compensates the toolface vector to account for an estimated geologic formation drift. The control system causes at least one control parameter to be modified in order to alter a drilling direction of the BHA based on the calculated toolface vector and transmits the at least one control parameter to the drilling rig to target the BHA in accordance with the calculated toolface vector. The control system iteratively performs this process until convergence with the desired target path is achieved.
