Abstract: The present disclosure provides novel systems and methods of locating downhole objects in a wellbore, the condition of casing within the wellbore, and characteristics of a subterranean formation. More specifically, data associated with a hydraulic impulse in fluid in the wellbore is used to determine a location of a downhole object. Data associated with the hydraulic impulse is collected and then processed in the frequency domain to identify the location of the downhole object. The downhole object may be a tool positioned within the wellbore or a fracture network that communicates with the wellbore by a perforation through wellbore casing. The system and method of the present disclosure can also be used to identify locations of unintended holes or perforations in casing and other tubulars.
