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. One aspect of the present disclosure is a system and method of locating a downhole object by analyzing pressure data from a hydraulic impulse transmitted through a fluid in a wellbore and that reflects off of the downhole object.
