Disclosed are systems and method for automating downhole drilling based on the profile and energy of the wellbore being drilled. One method includes advancing a bottom hole assembly (BHA) within a subterranean formation and thereby forming a wellbore along an actual wellbore path, the BHA including a controller module, one or more sensors, and a steering assembly, taking survey measurements with the sensors at two or more survey stations along the actual wellbore path, comparing the survey measurements with data corresponding to a planned wellbore path, determining a return path based on minimum energy of the actual wellbore path when the actual wellbore path has deviated from the planned wellbore path, and conveying a corrective command signal to the steering assembly in order to reorient a trajectory of the actual wellbore path such that it returns to the planned wellbore path. |
