1. A method for selecting a bottom hole assembly (BHA) to drill a borehole, the method comprising:
receiving, by a computing device, a drill plan for a borehole, the drill plan comprising formation information for one or more sections of the borehole;
accessing, by the computing device, data corresponding to each of a plurality of bottom hole assemblies (BHAs) comprising:
a neutral capability score responsive to rotary drilling data for each BHA;
a steering capability score responsive to data for a dogleg capability of each BHA; and
a sliding ratio score responsive to data for rotary and slide drilling by each BHA;
determining, by the computing device, an overall score for each of the plurality of BHAs based at least in part on the neutral capability score, the steering capacity score, and the sliding ratio score;
selecting, by the computing device, a BHA from the plurality of BHAs based at least in part on the overall score;
displaying the overall score and an identification of the selected BHA;
drilling at least a portion of the borehole with the selected BHA;
selecting a second BHA for drilling the borehole;
drilling the borehole using at least one of the selected BHA or the second BHA;
tripping out a drillstring from the borehole;
replacing the selected BHA with the second BHA on the drillstring or the second BHA with the selected BHA on the drillstring; and
drilling the borehole using the other of the second BHA or the selected BHA.
