Abstract
A hydrophone may be deployed in a wellbore to collect sounds that may be used to identify whether a wellbore is safe to operate. This hydrophone may include acoustic sensors that sense noise generated by motion of the hydrophone and may sense noise indicative of a defect that could lead to catastrophic failure of a wellbore. Noise generated by movement of the hydrophone may be classified as “road noise” and noise associated with wellbore defects may be classified being “signals of interest.” The presence of “road noise” may interfere with the collection of “signals of interest” and because of this, evaluations performed on data that includes “road noise” may result in inaccurate determinations and a decrease in safety. As such, systems and methods of the present disclosure are directed to improving safety of a wellbore by removing “road noise” more effectively while increasing quality of “signals of interest.”
