BIT BASED FORMATION EVALUATION AND DRILL BIT AND DRILL STRING ANALYSIS USING AN ACOUSTIC SENSOR

摘要

A drill bit having a bit body includes one or more acoustic sensors that are configured to detect elastic waves when the drill bit is used for drilling a wellbore. The acoustic sensor may be configured to detect a sonic signature associated with a failure event. In further arrangements, the acoustic sensors may be configured to receive signals from a controlled acoustic source.
