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.

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.

Seaco LT Overshot is one of the fishing tools in the external fishing pipe. It captures the collar, drill pipe, oil pipe, submersible pipe and other pipes. Because of the seal, the fluid can be circulated at high pump pressure after the fish is captured. The top of the fish will be ground with a shoe mill. It can also be used with jars to catch fish that get stuck. If it is not possible to release the caught fish from the jam, the fishing drum should be released and the drill string lifted.

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.

The internal catch mechanisms are of two basic types: a basket grapple and a spiral grapple. According to different uses, it may be equipped with some accessories, such as extension sub, wall hook, enlarged guide, etc.

We provide all kinds of fishing tools at various sizes.

Dropping stuff into a well, or worse, a person or animal falling into a well is a problem as old as mankind and wells.[See Luke 14:5 and Matthew 12:11.]

And I know about this "Honey I dropped the Pump" problem too, and haven"t added a full article on retrieving stuff from water wells at InspectAPedia because of lack of photos of the array of in-well-stuff grabbing tools, and also because I don"t think most homeowners will have much luck retrieving stuff that has fallen into their well on their own.

First off, it sounds like a horrible problem when a well pipe breaks and we drop stuff into the well. But don"t panic. You have to figure that you"re not the first people to have such bad luck - and it happens most often to well drillers not homeowners.

Because it does happen, just about every well driller and most plumbers who work on wells have a collection of grabbing devices, some of them home made, that can be lowered into the well to grapple around and grab on to the upper end of what now sits deep down in the well casing. It may take a few trials, but eventually they get stuff out by that method.

In that case the rigger brings in a truck or a portable winch system that includes a powered well pipe pulling mechanism that can handle the weight.

Certainly that device is used when, during the well pipe and pump pulling process, the operator has to stop to remove vertical lengths of well piping. Otherwise we"d have many feet of pipe sticking up in the air - creating another problem.

Then, trusting the clamp, the upper length of well piping is removed, the winch pulling connection is made to the newly exposed top of well piping just above the clamp, and the process continues.

You can infer from all of this, that in your case the bottom line is you"ll need to call your local well driller/well installer who should have the winch equipment as well as a clamping system to both grab and retrieve the top of the broken well piping as well as to pull it out without further catastrophes.

Magnets or junk magnets, are sometimes used to retrieve smaller metal objects that have fallen into a well; it"s doubtful that a magnet could pull a steel well pipe however. In the oil and gas industry junk magnets are run into a well ahead of a diamond drilling tool in order to remove metal junk that can damage the drilling bit.

Overshoots or Overshots are fishing devices that fit over the exterior of the well pipe and then grab onto the well pipe exterior to enable lifting the pipe.

Logan Oil Tools calls these "external catch" devices. [12] The overshot may be a metal mesh device, or a spiral device, one or more round or oval loops, or similar devices that grab on to the pipe exterior. The overshot was invented by Bowen in 1935.

Reamers: are devices used to ream out collapsed well casings in the oil and gas industry; [11] and those clever folks also use an impression block to figure out the shape of whatever it is that has fallen into the well if they don"t already know. [12]

Spears or releasing spears for well fishing are fishing devices that are inserted into the interior bore of a well pipe and then grab onto the interior sides of the pipe.

Logan Oil Tools calls devices of this sort "internal catch" devices.[12] Releasing spears include design features that can when appropriate release the "caught" pipe or component. Spearing tools are used to retrieve piping from a well when it cannot be grasped with an external catch tool.

See WELL FISH TOOL & CAMERA SOURCES at the end of this article for manufacturers of well retrieval tools, well pipe retrievers, well pump retrievers, specialty well repair tools, and for patented designs that suggest home made well pipe retrieval tools.

Boot baskets are used in oil and gas drilling to catch debris below the bit that are too heavy to be circulated out of the bore hole during the drilling procedure.

Cameras, Well-Bore Inspection - a well bore inspection camera can be lowered into the well to give a better understanding of exactly where your dropped obstruction lies and how to grapple-it.

Well bore inspection cameras can give a down view or side view or both simultaneously to identify and help retrieve obstructions, as well as to inspect the condition of the well bore and well casing.

Die Collars - used to retrieve a lost well pipe, the die collar is a coupling lowered over the lost pipe; the gas or oil version may not be easily workable for a plastic water well pipe; see our "double bite metal loop" pipe retriever discussed below.

Grinders: in the oil and gas industry a "junk mill" is sent into the well to try to grind up smaller junk that has fallen into the well. The Junk mill works with a boot basket to retrieve the ground up stuff - if it works. This probably won"t help with water well troubles.[11]

Spears - are expanding devices inserted into the interior of the lost pipe. Pulling on a line attached to the spear (along with mechanical design of the spear) or turning it expand the spear inside the lost pipe.

Jars or bumper tools are designed to impact stuck pipes, spears or other components stuck in a well by hydraulically jarring the stuck component upwards or downwards.

Junk Mill Bits - also referred to as bladed junk mills, cement mills, taper mills, pilot mills, and similar but more heavy-duty conebuster mills, are used in the oil and gas industry to literally drill-through plugs, packers, cement, or stuff dropped into a well

Store bought or home made single or double bite metal loop well pipe retriever: some well pipes can be successfully retrieved by fabricating a flexible pair of metal rings with squared or sharp edges connected and hinged to a rod that is in turn connected to the bottom of a working pipe long enough to reach down to the top of your well pipe in the well. When the pair of metal rings slip over the exposed upper end of the well pipe, push the assembly a few feet further down over the pipe.

If you"ve got your design right (test it above ground first) when you pull up on the assembly the rings will hinge to an angle that will "bite" onto the vertical pipe in the well and allow you to pull the assembly back out.

A rope with a large sharp edged "washer" or any other round object that can be dropped over the well pipe can do this same job. Some technicians call this assembly a cam cleat but more often that"s a nautical device for halyards and one that doesn"t work in this application.

Box Tap / Die Collar, used to retrieve tubular fish tools that can"t be rotated. This is a special type of overshoot used to connect to the top of tubing or piing. See Overshoots below. Produced by Schlaumberger and others.

Casing Swage is a tapered tool used to restore dented or collapsed well casings to approximate its original shape. Note that these tools will not repair a casing that has been broken or corroded through. Well sleeves or casing section replacement is needed in those cases. Speaking strictly this is a casing repair tool not a well retrieval / fishing tool.

I"m doubtful this tool is able to grab a round well pipe (the maximum length is about six feet and the end looks like suction cups) but the company may have tool ends that can be adapted for that purpose.

Elevators: Well pipe grapplers, well pipe elevators, or well pipe grabbers that will grab onto plastic pipe or iron pipe down inside of a well casing are sometimes home made based on designs such as the items listed above. Shown above are a pair of (green) well pipe elevators, and below, a pair (red) casing lifters provided by Hole Products.

The Hole Products company explains that standard duty SD pipe elevators are used for lifting threaded or coupled pipe: the lifter slides against the bottom side of a pipe coupling, while the company"s HD pipe elevators are used for well casing installation, setting well screens and pulling pump columns.

Expanding rubber plug pipe retriever: a home-made stack of rubber plugs placed over a threaded rod can, if your well pipe is not too deep in the well, be pushed into the top end of the pipe in the well.

The down-end of your threaded rod is locked onto a washer and nut and rubber plug just small enough to force into the upper end of the pipe in the well.

If you can stab that plug into the well pipe you then tighten the upper end of the treaded rod (a nut and washer will do) until you"ve expanded the rubber plug enough to grab onto and lift the in-well pipe.

Pipes in oil and gas drilling become stuck in wells differently from what happens in a drilled water-well or borehole well, but some of the tools developed for the oil and gas industry may also benefit the water well drilling and well retrival tool industry.

Well pipes that fall into a water well borehole may become mechanically stuck, or corrosion in some cases may cause separation of metal well pipe sections or the dropping of a pump and pipe section down into the well. On occasion, a section of steel well casing itself may corrode and fall into the well as may a poorly-installed well casing repair sleeve.

The traditional freepoint tool is an electromechanical tool designed to measure the amount of torque or stretch of a given length of tubing, drill pipe, or casing. The traditional freepoint tool uses either bow springs or magnets to anchor itself inside the pipe.

After obtaining an estimate of the free point by using the pipe stretch estimate technique, the traditional freepoint tool is run in the hole to 1000 feet above the estimated stuck point. The tool is anchored in place. Stretch and or torque is then applied to the pipe.

The tool is then run roughly 500 feet past the estimated stuck point. Stretch and torque are applied, and readings are taken. If the tool indicates that the pipe is stuck at that point the tool is pulled uphole and readings are taken again.

The Halliburton Freepoint Tool is based around the magnetorestrictive property of steel. This principle states that when torque or stretch is applied to free pipe, the magnetization will change. Stuck pipe will have no change in magnetization. There is a magnet on the bottom of the tool that creates a small magnetic field.

There are four co-planar orthogonal multi-axis high sensitivity magnetometers located above the magnet. The magnetometers measure the change in the magnetization of the pipe. The pipe is set at neutral weight, then the tool is run downhole logging the entire pipe string. Once it is at the bottom of the string, torque or stretch is applied to the pipe.

The tool is then pulled uphole logging the entire string. The tool will detect differences in the magnetization of the pipe, thereby indicating free and stuck sections of pipe. - Wikipedia, retrieved 2016/05/31, original source: https://en.wikipedia.org/wiki/Pipe_recovery_operations

Hooking onto existing fittings on the well pipe in the well: if the length of pipe that fell into the well includes couplings or a pitless adapter fitting, often any small grappling hook and line can grab onto the edge of that protrusion and pull the assembly out of the well.

Pull slowly and smoothly and as soon as you can mechanically grab the end of the lost pipe as it emerges from the well, do so. The pipe tongs shown below, provided by Hole Products (cited below) are used to grip pipe for hoisting; this tool will automatically release the pipe when tension is released on the lift line.

Hydraulic Fishing Jars are tools lowered into a well that grasp onto the stuck pipe, fish, or component to permit freeing a stuck component by jarring it upwards or in some applications downwards or in either direction. (Schlumberger) Fishing jars are also referred to as fishing accelerators.

Magnets for use in a well bore: Hole Products and other well service companies produce powerful magnets that can be lowered into a well to retrieve tools or metal pieces of irregular shape that have fallen into a well and that can"t be grabbed by other tools shown here.

Shown below, a well magnet fishing tool set provided by Hole Products Company whose contact information is given below in this article. Depending on the magnet size these devices can lift 100 to 400 pounds. The largest magnet shown below is 5 1/2" in diameter so may fit inside a 6" well casing.

I"m a little nervous about this approach because if the attempt fails and you leave the hook and a section of line in the well you"ve added to the mess that needs to be pulled out of the well.

Overshot mesh well pipe or item retrievers for fishing stuff out of a well: the most effective tools we know about for pulling lost well pipes out of a drilled well are various versions of overshots. Overshots, an "overshoot" type tool, are a bit easier to get over the outside of a well pipe than spear type tools are to get into the well pipe, unless the upper end of the pipe is near the top of the well.

Some supplies use the term "recovery bell" for overshots. The overshot is a cylindrical or conical shaped (bell shaped) device lowered over the upper end of a pipe to be retrieved from a well. Some companies (Schlumberger) produce a releasing overshot or overshots used for jarring or stuck material backoff operations.

The overshot is lowered over the end of the pipe in the well. If there is enough friction around the object the braided sleeve will contract and grab the object when the line is pulled up - like that braided rush "chinese finger trap" trick we played with as kids.

The overshot is attached to the end of a drilling rod or in the water well industry to the end of a section of well piping that is lowerd into the bore hole.

Some overshots include hardened self-cutting threads that will grab onto the upper end of a well pipe that has been dropped into the well borehole, thus allowing the pipe to be retrieved.

Pin Tap / Screw-In Sub taps are used to retrieve a tubular fishing tool or pipe from a well when it is cannot be rotated. Basically this is similar to a "screw extractor" that is reverse-threaded to be turned into a seized bolt, screw, or in this case pipe or fishing tubular tool that cannot be turned or rotated in its normal direction. Produced by Schlumberger and perhaps others. Also see Taper Tap.

PVC Well Casing Elevators: a special clamp-on elevator tool is required to lift a PVC casing or casing liner without breaking it. The tool shown below is provided by Hole Products whose contact information is given below in this article.

PVC glue-on well pipe retrieval: some report success by lowering a new section of PVC pipe down into the well onto the lower end of which has been cemented (and dried) a coupling that will just fit over the exposed top of the plastic well pipe that is already in the well.

With fresh glue inside the mating end of the coupling the retrieving well pipe section is pressed down onto the exposed top of the pipe that is already in the well. Wait for the glue to dry and try pulling out the whole assembly. If the broken-off plastic pipe is below water level, or badly damaged, this approach may have poor chances of success.

Releasing spear well retrieval tools: a releasing spear is a well pipe or tubing retrieval tool that includes an internal catch that retrieves pipes or tubing from a well bore. The releasing spear is lowered into the well where it "spears" the interior of the pipe to be retrieved. Bowen® Itco is a producer of releasing spears.

Taper taps are described as rotary taper taps (most-commonly used for conventional retrievals) and coring taper taps used for wireline coring operations. Also see Pin Taps.

Taper Taps are produced by Produced by Schlumberger (shown above), Hole Products, and perhaps others. Hole Products also supply sonic taper taps sued to retrieve lost sonic tooling. Contact information for these companies is given below. Similar tools include packer milling and retrieving tools designed to drill through plugs in a well bore.

Washover shoes, (shown above) strictly speaking are not retrieval tools but rather devices that are used to free pipe that has been stuck or lodged in a well bore due to fallen debris or other obstructions.

Watch out: when buying or fabricating a tool to pull a dropped well pipe or something else out of a well, be careful not to drop your new tool into the well alongside what"s already in there. Test your device above ground first and also be sure it"s strong enough and long enough to do the job.

Note that the primary producers of well retrieval and fishing tools are companies serving oil and gas drilling industry companies. However many of these also serve the water well drilling industry too.

Check with your local well driller as those folks will have more experience, retrieval tools, and probably safer procedures than a normal property owner. The savings in time and money by hiring a professional may be more than you first guess.

I don"t have comment to you because is my first time to see some of fishing tools and the quality are good but my humble request is how can a pump machine like me who can"t afford to get or buy can manage to have it.

I was trying to check the static water level thru the little vent screw on the top of the well casing with a 4 OZ lead fishing weight . It got stuck and then it came untied.

I have a tool I made in my machine shop that will go get ANYTHING in a water well or oil well no difference not like the stuff shown here. Drop a pipe wrench in the hole I will have it back in 5 minuets guarantee. 93sixsevenone 8 one three two 5

I dropped a key chain into a 4" steel casing monitoring well yesterday and i am trying to find ways on how to retrieve it. I have tried fishing hooks with no luck, any ideas?

You are welcome to post a photo of your tool here and if you use the page top CONTACT link we can look at your info for addition to sources of well pipe grabbing tools in this article series.

. It will go any distance bring back anything. It will retrieve and bring it back in about 10 minutes. There is only one of theses tools in the world and I made it. I can make one for any size Id pipe. If you need one contact me. Century Foundation Company magnolia Texas is on net.

What the other pro"s do - and they"ve all dropped a pump at one time or another - is try a series of various grabber hooks such as those shown in the article above;

When you lower a well cam you can see if there is a rope or pipe that"s likely to be able to be grabbed by one of the retrieval tools we illustrate; you basically have to match the tool to the space available, to what"s in the well, and to the position of the fallen materials.

Aside from the dropped well pump or pipe tools shown in our article above, I"ve read that some well pump retrieval projects had success by trying a piton or crevice clamp (mountaineering equipment) or even a simple small grappling hook that snagged a dropped well rope.

Keep in mind that your retrieval cable or pipes have to be strong enough to lift ALL of the weight involved: pump, pipes, wire + some strength to pull and wiggle through snags.

Hello. I have recently pulled the pump that is in our deep well system and bought a replacement. I attempted to install the new pump and all was goin well until I got to ab 200 ft down with pump and the pipe((its 440 ft to the bottom of the casing and top of the water is ab 200 ft)) and it happened so fast- I couldn"t grab it or anything-- IT FELL!!!

Well- I spent days pondering on how in the world I could get it out and finally - I got a 250 ft auger and joined it with another auger. I winched it up and got the pipe and tied icecycle knot and tied it off.

The wire had fell with it so instead of pulling all of it back up and checking the pump- I just connected it to 220 v breaker to see if i could hear or feel the vibrations-- so I would know that it wasn"t damaged or broken... longer story short.... it did vibrate the top of the pipe that I had knot tied to and so I connected 3 more (20 foot long ea) 1 in pipes.

And got it where I thought it was in water ab 240 ft and when I connected it to the 220 breaker this time--- there was no vibration or any noise so --- I had to hoist it back up---

finally got to the bottom and the water pump wasn"t at the end of the pipe.... the wires had somehow been severed and I"m not sure how or why it happened but I need advise on tools that I could use or make to use to grab onto the piece of pipe and pump that is still sitting at the bottom of our deep well.

I"ve tried auger and I get a hold on it but b4 I make it out of the water with it it"s getting stuck or either falls off the end of the auger... any suggestions r welcomed. I really need another opinion on this-

I lost a section of pipe and a tool in my well trying to pull out what was dropped in by a previous well company. The pull line broke. Can I just leave it there?

Ugh, Bill, I hate when that happens. I speculate that what you snagged were remains of someone"s previous attempt to sound the depth of the bottom of the well. Feel better, they, too, lost their weight and hook before you came along.

Steve: my comments and opinion above to Bill pertain to your well fishing too. But also we"d prefer not to leave lead items in the well. I"m not sure how much two small lead weights might contribute to detectable lead in your water supply: that would depend on water chemistry, its corrosivity, the formation of a lead oxide coating on the weights themselves, and how much water movement occurs in the well.

Leaving them until they clog the pump or foot valve might result in loss of water supply at an inconvenient time (say during Thanksgiving when you have many guests but suddenly there is no water to drink nor to flush a toilet), and pulling the pump is perhaps more costly than another attempt to fish out the fallen stuff in the well.

I dropped my wedding ring down my well in my back yard the opening is about 6 inches across and I"m not sure how deep it is.. how can I get it out. Please help... =-O

It"s probably possible to retrieve the ring, though it"ll be some trouble. Check with your well driller to see what small-object retrieval tools they have on hand. There are two approaches:

2. With the pump and piping out of the way and depending on well depth, your well service company might be able to use a 2-line jet large venturi vacuuming approach to see if they can pick up and pump well bottom debris through a screen to catch your ring. This is the most likely approach if someone local is willing to set it up for you. Some well drillers offer this service under "well cleaning" procedures and may use a compressed air source rather than a 2-line water jet system.

3. a jet-venturi system used in oil drilling rigs and possibly some well operations can also retrieve small objects but I"d be careful about using this approach as if the bottom of your well has inches thick sediment we don"t want to risk pushing the ring deeper into the sediment.

Fair question, Tina but prices are all over the place depending on the particular pipe grabber tool and its appilcation, from $10. to $1000 or more. The "Fetch" pipe spear described in the article above retails for about $500. U.S.

Have a 40 year old cliton formation well has 3" tubing as casing and a slip tooth from an 1 1/2 well head and is stuck 1,700 ft down what would be the cheapest way to remove it. Trying to plug the well and need to get to bottom around 4,000 ft and theirs a hole in the 3" pipe any ideas or will I have to shoot it off above the slip and run tubing in and swallow the 3" with a cutter and cut it off

Other readers: Mr. Myers reference to a "slip tooth" probably refers to an anchoring mechanism for a well tool that allows for movement in directions other than straight vertical.

The most expert deep well drillers in the world come from the oil and gas fields. One of their approaches for tool jams such as the one you describe, if a grabbing tool can"t remove the fallen object, is to drill through it.

I got an old shallow well and my inner pipe is a inch and a quarter inside the case and the top three threads broke off when was trying to pull it out what kind of tool do I need to get that inner pipe out and where can I find it

While I like a pipe spear for the situation you describe, most of the well pipe grabbers described in the article above or a home-made version of one of them ought to work; to save time and trouble give your local well drilling contarctor a call as they probably have several of these tools at hand plus the lift or winch needed.
