DOWHNOLE CUTTING TOOL HAVING SENSORS OR RELEASABLE PARTICLES TO MONITOR WEAR OR DAMAGE TO THE TOOL

摘要

A wellbore formation system includes a downhole cutting tool having a body and at least one cutting element. A sensor is coupled to the downhole cutting tool, and the senor includes a transmitter configured to transmit a signal prior to wear on a portion of the downhole cutting tool reaching a first amount. The sensor ceases transmission of the signal when the wear on the portion of the downhole cutting tool reaches the first amount.
