1. A system for use in a well, comprising:
- downhole equipment for positioning in the well;
an optical fiber for deployment in the well, the optical fiber to extend to a location of interest in the well in a proximity of the downhole equipment; and
an analysis unit to analyze detected light signals returned from the optical fiber that has been affected by acoustic events generated by the downhole equipment and to determine a status in the wellbore based on the analyzing.

Abstract
A system for use in a well includes downhole equipment for positioning in the well, and an optical fiber for deployment in the well, the optical fiber to extend to a location of interest in the well in proximity of the downhole equipment. An analysis unit analyzes detected light signals returned from the optical fiber that has been affected by acoustic events generated by the downhole equipment and to determine a status in the wellbore based on the analyzing.

13. A method of monitoring a condition in a wellbore, comprising:
-
receiving backscattered light signals from an optical fiber deployed into the wellbore, wherein the optical fiber has a portion for monitoring downhole equipment in the wellbore, and wherein the optical fiber portion has a characteristic that is modified in response to an acoustic event associated with the downhole equipment; analyzing a signature derived from the received backscattered light signals, wherein the signature is representative of the acoustic event; and providing information relating to a status in the wellbore based on the analyzing. - View Dependent Claims (14, 15, 16, 17, 18, 19)
