Fishing tool is a special fishing drilling tool used to retrieve fallen objects from the borehole. At any stage of the operation, the drill rig operator will encounter unexpected situations, such as falling drill string, stuck pipe, missing drill bit, etc. The equipment that falls into the well is called "fish" or "trash", and the tools used to remove the equipment are called "fishing tools." Sometimes it may be necessary to use "fishing tools" to retrieve older wellbore equipment, such as packers, liners, tubing, or any stuck objects in the well. The drilling tools for fishing must be retrieved from the borehole in order to continue drilling operations.

Overshot is a very common fishing tool. The main fishing object is a smooth tube fish, which belongs to the external fishing type (i.e. catching the external surface of the fish).

Taper tap and die collar are common fishing tools for fishing the inner hole of the string. They are used for fishing the inner hole with holes such as tubing, drill pipe, casing milling pipe, packer, water distributor, etc. It is made of high-quality alloy steel and especially heats treated. It has the advantages of high strength, high toughness, and simple buckle making.

GAOTON Series 150 Releasing and Circulating Overshot is an external fishing tool for engage, pack off and retrieve tubular fish, especially for fishing drill collar and drill pipe. The grapple of the overshot can be designed for different sizes of fish, so one overshot can be dressed with different size of grapple components for fishing different sizes of fish.

GAOTON Series 150 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.

Within those famous China oil and gas overshot manufacturers, GAOTON is a professional such supplier, producer and provider, welcome to wholesale petroleum and oilfield API overshot from our factory.

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:

Hydraulic casing spears are run above a mechanical or hydraulic inside casing cutter, allowing cutting and casing pulling in one trip. The spears are set and released hydraulically for ease of operation and no need for mechanical intervention.

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.

The Type E™ casing spearprovides effective casing retrieval in the most severe downhole environments. With its heavy-duty, high-strength design and simple construction you’re assured reliable performance and easy operation and maintenance for a wide variety of casing sizes and weights.

Drilling tool fishing is probably every driller’s least favorite activity. But it happens. There are a huge number of tools available to fish almost anything out of the hole. For drill pipe and collars, there are overshots and spears — in many sizes for almost any job. But, when it comes to loose junk on the bottom of the hole, things get a little more interesting. It might be a loose bit, a wrench, a sledge hammer or tong dies. Anything that can fit in the hole will sooner or later end up on the bottom. I reckon it’s human nature, or Murphy’s law, but it happens.

Most commercial fishing tool companies have pretty sophisticated tools, such as reverse circulation junk baskets, and all kinds of well-engineered tools to do the job. But, sometimes, they are not quite what a customer needs. If the fish is large in relation to the hole size, such as a bit, a reverse basket will not pick it up because of the wall thickness. Something else is needed. Or, if the hole is just not worth the expense of using a commercial fishing company, a driller may opt to build his own fishing tool for the job.

This brings me to a tool that is often overlooked, but has been around forever and recovered a lot of junk in the hole: the poor-boy basket. Most fishing companies don’t push them because they are not fancy high-dollar tools that make great testimonials, but they work and can be built by the driller on location.

A poor-boy basket is basically a short piece of casing with fingers on the bottom that swallow the fish and close below it, making a successful recovery.

The layout and design of the fingers is very important to the operation of the tool and successful recovery of the fish. I have built these for years and pretty well have it down, so I thought I’d share with you how to lay out the leaves on a poor-boy basket for your best chance of recovery.

As I said, the diameter will be about as big as you think you can get into the hole. Measure the diameter of that casing, and make the basket about 25 percent longer than that number. It tapers into kind of a bullet shape. At one-third the length of the basket, it should taper to seven-eighths of the original diameter. At two-thirds the length of the basket, it should taper to one half of the original diameter. Cut the leaves so that they tend to close on right-hand rotation.

Once you’ve built your basket, here is the running procedure:Go in the hole at moderate speed, watching for ledges or doglegs. The basket is a delicate tool, and you need it intact when you get to the bottom.

Very slowly lower the string to drill over the fish. You should not see any weight loss on the indicator. The best way is to time drill. Lower the pipe about ½ inch every minute or two. Watch your pump pressure and torque.

If you are in soft formation, you will core into the formation, trapping the fish in the basket. In this case, you will see an increase in pump pressure when the leaves have passed the bottom of the hole, and torque will increase.

At this point, while still rotating, significantly increase the weight on the string, while watching your torque. This will close the leaves below the fish, and break any core you have cut.
