Claim:
1. A bottom-hole assembly, comprising: a drill bit and a reamer axially offset from the drill bit; a first sensor sub arranged proximate to the drill bit to monitor a weight-on-bit; a second sensor sub arranged proximate to the reamer to monitor a weight-on-reamer; a communications module communicably coupled to the first and second sensor subs and configured to receive and process the weight-on-bit and the weight-on-reamer; and one or more adjustable nozzles included in each of the drill bit and the reamer, wherein each adjustable nozzle is communicably coupled to the communications module and is independently actuatable by the communications module to adjust a hydraulic energy input to the drill bit or the reamer, wherein adjustable nozzles included in the drill bit are actuated to adjust a hydraulic energy input to the drill bit when the weight-on-bit is greater than the weight-on-reamer, and wherein adjustable nozzles included in the reamer are actuated to adjust the hydraulic energy input to the reamer when the weight-on-reamer is greater than the weight-on-bit.
