Abstract
Certain aspects and features of the present disclosure relate to real-time management of excessive torque, drag, and vibration along a drill string. In some aspects, torque, drag, vibration or any combination of these may be monitored at locations along the drill string, and these forces may be mitigated by adjusting the drilling fluid composition in real time. In some aspects, the forces may be mitigated by making real-time operational changes during wellbore drilling instead of or in addition to drilling fluid treatments.
