Abstract
A system includes a bottom hole assembly (BHA) that includes a drill bit configured to drill a pilot hole in a subterranean formation, such that the drill bit provides a first point of contact between the BHA and the subterranean formation. The BHA includes a steering pad assembly that includes one or more steering pads each configured to move over a path of travel between a retracted position and an extended position to provide a second point of contact between the BHA and the subterranean formation, and a reamer configured to expand the pilot hole into a borehole, such that the reamer provides a third point of contact between the BHA and the subterranean formation. The system includes a controller configured to steer the BHA via the first, second, and third points of contact and adjustments to the second point of contact via control of the steering pad assembly.
