A general term for special mechanical devices used to aid the recovery of equipment lost downhole. These devices generally fall into four classes: diagnostic, inside grappling, outside grappling, and force intensifiers or jars. Diagnostic devices may range from a simple impression block made in a soft metal, usually lead, that is dropped rapidly onto the top of the fish so that upon inspection at the surface, the fisherman may be able to custom design a tool to facilitate attachment to and removal of the fish. Other diagnostic tools may include electronic instruments and even downhole sonic or visual-bandwidth cameras. Inside grappling devices, usually called spears, generally have a tapered and threaded profile, enabling the fisherman to first guide the tool into the top of the fish, and then thread the fishing tool into the top of the fish so that recovery may be attempted. Outside grappling devices, usually called overshots, are fitted with threads or another shape that "swallows" the fish and does not release it as it is pulled out of the hole. Overshots are also fitted with a crude drilling surface at the bottom, so that the overshot may be lightly drilled over the fish, sometimes to remove rock or metallic junk that may be part of the sticking mechanism. Jars are mechanical downhole hammers, which enable the fisherman to deliver high-impact loads to the fish, far in excess of what could be applied in a quasi-static pull from the surface.

When you can’t reliably engage your fish with drillpipe, rely on the reliability and flexibility of fishing internal and external engagement tools from Baker Hughes.

Externally engage, pack off, and pull a fish with our wide range of overshot tools. The first fishing choice when screwing into the fish is not an option, our overshot tools are simply designed but ruggedly built. Choose from options including:

Kelo socket overshots are proven to catch small-diameter workstrings and sucker rods inside casing as well as recover coiled tubing that has parted and remains in hole.

The t-dog, mouse-trap, and flipper-dog (TMF) overshot can be dressed in three different ways for different washover applications. Deploy the t-dog assembly option to washover and recover mud-stuck or sanded-up square-collared pipe in one trip. Use the mouse-trap assembly to catch sucker rods, integral joint tubing, or cables. And with the flipper-dog assembly, you can confidently catch a fish with different ODs.

If your fish cannot be externally engaged, our range of releasable spears provide a viable retrieval option. These internal engagement tools come in a variety of designs, including:

Type B™ and Type D™ casing and tubing spears retrieve a full range of casing sizes. The design of these spears affords easy dressing for alternate casing sizes, simple field-dressing to change the release setting, and fast, effective release—all of which help improve the efficiency of your fishing operations.

Stuckey’s Specialty Tools’ releasing and circulation overshot is the strongest available fishing tool for externally engaging, packing off or pulling a catch. Its basic outside construction consists of a top sub, the bowl, and the guide. The internal parts depend on the catch desired. A spiral grapple, spiral grapple control, and type "a" packer can be used or a basket grapple and a mill control packer.

Stuckey’s Specialty Tools’ releasing and circulation overshot requires only right hand rotation during both engaging and releasing operations. No damage or distortion results to the catch or the overshot due to the helically tapered spirals on the inside diameter of the bowl.​

The Hunting Releasable Overshot is designed to engage tools that have damaged or have no fish necks. The Overshot is designed to withstand high impacts associated with fishing operations.

The unique design of the core allows the reach to be altered to suit the required length without the need to carry extra cores. The quantity of slips has been minimised providing greater coverage of different tool OD’s.

Hunting Releasable Overshots are available in all common industry toolstring sizes and are manufactured with either sucker rod or integral quick connections as per customer requirements
