Abstract

A method includes receiving toolface information corresponding to a location of the bottom hole assembly (BHA) with respect to a target drilling path and drift information. The surface steerable system calculates a first toolface vector from a first location of the BHA to the target drilling path to create a convergence path to the target drilling path and calculates an adjustment of the first toolface vector to a second toolface vector to account for system drift defined by the drift information such that the BHA will converge with the target drilling path by drilling in accordance with the second toolface vector. The surface steerable system modifies at least one drilling parameter to alter a drilling direction of the BHA based on the calculated second toolface vector and transmits the at least one drilling parameter to the drilling rig to target the BHA in accordance with the second toolface vector.
