Abstract

A system for optimizing a rate-of-penetration of a drill string includes a plurality of sensors in operable communication with the drill string; and a controller in operable communication with the plurality of sensors. The controller is connectable to a drill string motivator and capable of outputting a signal to the drill string motivator for optimizing the rate-of-penetration of the drill string, and the signal is configured to provide at least one of weight on bit, an amount of speed to rotate the drill string, an amount of torque to be applied to the drill string, and an amount of mudflow to the drill string.
