If the catched fish can’t be release from stucking ,we could release the overshot and lifting the drill string.Overshot consists of three outside parts: top sub, bowl, and standard guide. The basic overshot may be dressed with either of two sets of internal parts, if the fish diameter is near the maximum catch of the overshot, a spiral grapple, spiral grapple control, and type “A” packer are used. If the fish diameter is considerably below maximum catch size (½” or more) a basket grapple and a mill control packer are used.
