Overshot is one of the fishing tools which is fishing the pipes externally. It can catch drill collar, drill pipe, tubing, subs and other pipes. Because of the seals, the fluid can circulate with the high pump pressure after catching the fish. The top of the fish will be milled by under mill shoe. It can also work with jars to catch the stuck fishes. If the catched fish can't be release from stucking, we should release the overshot and lifting the drill string.
Overshot assembly consists of a Top Sub, Bowl, Basket Grapple Control,and a Basket Grapple. Although the short catch overshot has no Guide,the components function in the same manner as the standard Releasing and Circulating Overshot. Operation of the Short Catch overshot is identical to standard Releasing Overshot.
Catching the fish: attach the overshot to the bottom end of the fishing string and run it into the hole. The overshot assembly is rotated to the right and lowered as the fish enters the expandable grapple. With the fish in the grapple, stop right-hand rotation and exert an upward pull to fully capture the fish.
Releasing the fish: a sharp downward force( bump) is applied to the overshot to break the hold of the grapple within the bowl. The overshot is then rotated to the right while it is slowly elevated to release the grapple from the fish.

1.top sub connection.
