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.
