Abstract
An apparatus and method for removing fish from a well, said apparatus including a top sub with upper and lower ends, the upper end adapted to be connected to a drill string, a grapple sleeve connected to the lower end of the top sub and a grapple, which in the preferred embodiment incorporates grapple fingers so as to externally engage and grasp a fish in a well slidably mounted within the grapple sleeve. The grapple is mounted to the top sub and extends out of and into the grapple sleeve such that once the fish is engaged the grapple may be withdrawn into the grapple sleeve, which in turn allows for the maintaining of a constant force on the grapple and fish engaged therein. The method of the present invention includes running into the well a drill string having a grappling tool attached thereto, locating the fish by making contact with the grappling tool, engaging the fish with the grapple, and removing the fish from the well.
