fishing overshot factory

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.

The Coil Solutions Overshots are used to engage and pull a fish from the well bore. It uses a grapple to bite into the outside of the fish and releases by following through a predetermined rate to disengage the grapple. The tool comes with a range of grapples to accommodate various fish sizes.

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.

All of our fishing tools come with standard API threads. In our machine shop we can cut any thread or customizes a drilling tool solution for your needs. Our fishing tools range in size from3.5" OD - 24" OD

This drilling tool is an Over shot fishing tool. To construct this part it we manufacture in a similar fashion to the fishing spear. The over shot is precision CNC machined from hardened high alloy steel. And has a sharp internal thread profile. This fishing tool latches to the outside diameter of the broken down hole drilling tool. The hard sharpened threads are designed to latch and thread into the part.

The Fishing spear is a tapered down hole fishing tool that is designed to cut a thread into in inside bore of the rotary drilling tubular. Our manufacturing process specifies us to cut a sharp profile thread into case hardened 8620 high alloy steel. We do this in house with our CNC machine shop. This guarantees it will bit into the broken tubular.

A premium magnetic fishing tool that is also very inexpensive. It comes standard with a removable reaming bit which helps to stabilize it while down the hole. Our magnetic fishing tools pull over to 3501bs in testing, but we can design them to pull even more. Our fishing tools have open holes designed to allow the face of the tool to be flushed. This allows for good hole cleaning and helps insure random debris does not become magnetised and junk up the face of the tool. The magnetic fishing tool is designed to be used with none hibulars

Our hydraulic and mechanical jars are designed for releasing a stuck downhole tool by up-and-down impacts with static axial load (tension) and torque. Jars are included in drilling assemblies for sidetracking. We produce right and left hand fishing & drilling jarsas well as brand-new torsiconial jars purposed for releasing stuck tools by up-and-down torsional impacts.

The slip overshot is an unreleased tool designed to externally engage a fish .It not only can engage every kinds of oil tube, drill pipe, weight rod, long plumb but also can reverse the stuck pipe string by giving torque to the stuck pipe string

Tango stocks an extensive range of external catch fishing tools. External Catch Fishing Tools engage the fish on its outer diameter. These tools help you recover equipment downhole by using a grapple or by threading directly to its outside surface. These tools include:

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.

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.

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.

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.

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.

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.

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.

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 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?

I don"t much like the idea of leaving debris in a well, though it may have no effect until fishing line fouls a foot valve or bits enter a pump through a well screen.

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.
