Patent number: 9753171Abstract: A sensor for detecting well conditions includes at least one transducer positioned at an end of the carrier. The carrier is positioned adjacent to and exposed to a wellbore wall and the transducer is configured to generate mechanical waves in the carrier. The carrier conveys the mechanical waves and has one or more sections initially free of a physical deformation that causes reflection of the mechanical waves. The sections physically deform to cause reflected mechanical waves when subjected to a loading from the formation. The transducer generates a signal representative of reflected mechanical waves received at the end of the carrier. The location of the loading is estimated using the received signal.Type: GrantFiled: October 15, 2014Date of Patent: September 5, 2017Assignee: BAKER HUGHES INCORPORATEDInventors: John C.
