      Diagram

      Overshot is a downhole tool used in fishing operations to engage on the outside surface of a tube or tool. A grapple, or similar slip mechanism, on the overshot grips the fish, allowing the application of tensile force and jarring action. If the fish cannot be removed, a release system within the Overshot allows the overshot to be disengaged and retrieved.
