摘要

Overshot fishing tools for retrieving objects, i.e., “fish” lodged within a wellbore are disclosed. The overshot fishing tool comprises a housing having a housing bore with at least one recess disposed along the inner wall surface of the housing bore. A slip is disposed within each of the recesses. Each slip has a gripping profile for engaging and securing the fish. Each slip also has a length and a width such that the slip, when actuated, provides circumferential loading on the housing. In specific embodiments, each slip includes two or more different gripping profiles to facilitate retrieval of different types and sizes of fish.
