Systems and methods of adjusting weight on bit and balancing phase
Abstract:
Disclosed are systems and methods of balancing weight distribution between downhole cutting tools. One system includes a drill bit arranged at a distal end of the bottom-hole assembly, a first sensor sub arranged proximate to the drill bit and configured to monitor one or more operational parameters corresponding to the drill bit, a reamer axially-offset from the drill bit on the bottom-hole assembly, a second sensor sub arranged proximate to the reamer and configured to monitor one or more operational parameters of the reamer, and a communications module communicably coupled to the first and second sensor subs and configured to communicate one or more corrective action signals when the one or more operational parameters of the drill bit and the reamer surpass a predetermined operating threshold.
