Abstract: A mechanical perforation locator has a plurality of perforation locator pins that are normally urged to a run-in condition. Fluid pumped into a work string energizes the perforation locator and urges the perforation locator pins outwardly. When the mechanical perforation locator is pulled or pushed through a cased well bore using the work string, some of the pins are forced into perforations in the casing, which impedes movement of the perforation locator and produces a characteristic spike in work string weight that is detectable at the surface.
