overshot drilling in stock

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.

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

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.

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.

Overshots are a tool used on the downhole process during the fishing operations. It engages the tube or tool on the outside surface. A Grapple or other piece of equipment that is similar attaches onto the overshot and grabs the fish.

A downhole tool used in fishing operations to engage on the outside surface of a tube or tool. A grapple, or similar slip mechanism, on the overshot grips the fish, allowing application of tensile force and jarring action. If the fish cannot be removed, a release system within the overshot allows the overshot to be disengaged and retrieved.

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.

Next, the trip is made with an overshot and jarring assembly to engage the fish. When the washer over has freed all of the remaining fish, it is pulled from the hole. If only part of the fish is free following washing over, the freed portion is cut or backed off and pulled so another washover can begin. If the inside of the fish is plugged preventing entry of wireline tools, the tubing can be recovered with an outside cutter. Following washover, the shoe is removed and replaced by an outside cutter on the bottom of the washover string. The cutter is run over the top of the fish to the desired depth and the tubing is mechanically cut by rotating the string.the cutter then acts as a retriever and the plug tubing can now be brought to the surface inside the wash pipe.

in sandy environments, a gravel pack assembly may be located below the packer. Its removal is accomplished using conventional washover, milling and retrieval tools. However, when rapid sand backfilling is likely and where the gravel pack assembly may become restart while tripping the by foreign overshot, a trip saver tool is recommended. The trip saver is run in place of the top bushing of the washpipe. It provides a mandrel on which an overshot can be placed inside the washpipe. After wash over has completed, the well as circulated clean. The manrole with the overshot is released from the washpipe top and lowered until the overshot latches to the gravel pack assembly ensuring efficient one trip retrieval.

Another major area requiring cased hole fishing focuses on casing problems themselves. When leaks are located in free pipe above the cemented level of the casing, the casing is cut or backed off below the problem area and replaced with new pipe. If the casing was backed off, the new casing is run back in the well and the string is screwed back together. If the casing was cut, it is dressed off to remove birders and external casing badges then screwed onto a string of new casing and running the hole. The patches engaged on to the or gazing in a manner similar to an overshot and the gentle upward pull collapses the seal assembly made of lead or rubber around the casing. The entire string is pressure-tested to ensure a good seal.

When all casing repair methods fail, it becomes necessary to sidetrack if the well as to be saved. Although a sidetrack can be accomplished by cutting or milling a section through the casing and then drilling out using a directional assembly using up whipstock to mill a window is usually the most effective and least costly procedure to establish a sidetrack.

In medium radius horizontal wells, it is sometimes a good idea to make one additional mill run if a long horizontal area is to be drilled. This run will lengthen the window making it easier for the drilling assembly to pass through the window when horizontal reaches long and dragged become severe. Once the new radius or sidetrack is complete, the whipback can be recovered using a special retrieval hook or a threaded die collar. This is particularly useful in producing wells where multilateral boards are added to an existing productive interval.
