I debated on where to go next, but at the end of the day the most widely used fishing tool has to be an overshot. Some will say why not a spear? Well if you must ask, always go with the strongest fishing tool you can run to catch the fish. And if you run a spear, never plug the I.D. of your fish by breaking it off. Done with that!

The info that follows has been taken from the manuals published on overshots. I realize that paper manuals are a thing of the past, yes, yes at one time fishing tool hands carried massive catalog brief cases full of reference material. Now you have the luxury of your laptop loaded with information. If you have never sat down and read an overshot manual, now might be a good time.

The overshot is highly versatile and efficient tool. There are several different types of overshots, however each overshot is designed to engage a specific size of tubing, pipe, coupling, tool joint, drill collar or smooth OD tool.

The original overshot was developed by Bowen Oil Tools, which is now part of NOV. One thing I will point out is that in the catalogs you will see more than one assembly number for a given OD of Overshot, this came about due to the two locations developing their own variations. I found this information on NOV’s website and thought it was interesting to share.

Bowen™ became a leader in innovation with the creation of the first overshot, the Series 150, in 1935. This tool set the standard for fishing equipment, and the quick acceptance of the tool assured the company partners that their business would be successful. The company continued to create new products, building a reputation for their well tool design and construction.

Currently there are several manufacturers of overshots, NOV (Bowen), Rubicon (Logan) and Applied Oil Tools (Gotco). These overshots are designated by a series number as follows:Series 10 - Sucker Rod Overshot

Overshots may be identified by one of the following, known as “type”:Full Strength (FS) - engineered to withstand all pulling, jarring and torsional strain

The basic overshot (from top down) consists of a top sub, a bowl, grapple, control, and a guide. In addition to the basic components, some overshots (Series 10 and 150) can be dressed with either a:Spiral grapple used if the fish diameter is near the maximum catch of the overshot, or a

The Series 150 Overshot features the ability to packoff on the fish. When the circulating packoff is not used, the fluid circulates down the drillpipe, aroundthe top outside of the fish, through the slip or grapple assembly, around the guide shoe and up the annulus.

When the circulating packoff is used, the annular space between the top outside of the fish and the inside of the lower part of the overshot is packed off, diverting the fluid flow down into the fish, making it easier to release and recover the fish. Packoffs usually are not high pressure devices but will often withstand sufficient pressure to establish circulation through the fish. Third party high pressure packoffs are available from various sources.

The extension can be installed between the top sub and the bowl of the Series 10, 70, and 150 overshots. It is used to extend the overshot bowl to:Allow the grapple to catch farther down on a fish that may be necked down at the top by having been pulled in two, or latched by an overshot and released several times, or to

A stop ring must be used where a fish OD reduces immediately below the catch area to allow the grapple to bite on full-size pipe.Example - catching a Hydril upset or EUE collar. If the upset of collar should pass completely through the grapple, the overshot may not be releasable.

The Series 10 Sucker Rod Overshot is designed to engage and recover sucker rods, couplings, and similar items from inside tubing strings.Basket grapples are recommended for fishing for hardened and ground boxes (Sucker Rod Box).

The Series 20 Sucker Rod Overshot is a short catch tool which provides a means for engaging the exposed portion of a fish too short to be engaged with a Series 10 overshot.Uses basket grapples only

The Series 70 Short Catch Overshot is designed to engage the exposed portion of a fish too short to engage with Series 150 overshots.Uses basket grapple only

The Series 150 Releasing and Circulating Overshot is used to engage, packoff, and retrieve twisted-off lost tubing, drillpipecoupling, tool joint, casing or other similar fish.

A right hand wicker grapple converts a normal right release overshot to left hand release. This grapple is used where you expect to apply excessive right hand torque to release a packer, safety joint, etc. Note: Overshot will have to be released by left hand rotation.

Grapple Controls:Basket Grapple control packers have built in packoffs. These packoffs will hold various amounts of pressure, depending on the size of the fish and the condition of the packoff after engaging the fish.

High Pressure Packoff Assemblies:The High Pressure Packoff Assembly is an accessory to the Series 150 Overshots. It is used when high pressure circulation to the fish is required. It consists of a packoff sub with packing and packing rings and is installed between the top sub and bowl of the overshot. By running the packoff sub above the bowl, this design prevents the application of high internal pressures to the overshot bowl. The design of the High Pressure Packoff Assembly allows pressures two to three times the standard overshot packoff to be applied to the fish.

This information comes directly from the NOV manual for the Wide Catch Overshot. This is probably the first and only change to this common tool I know of in my career.

The Wide Catch Overshot provides the strongest tool available to externally engage, pack-off, and pull a fish that has been significantly worn. This tool has similar rugged design features and construction as the industry standard, Bowen Series 150 overshot, with the ability to interchange the Bottom Guide with the full range of existing components used with the standard Bowen Series 150 overshot.

In service, the Wide Catch Overshot (WCOS) takes a positive grip over a large area of fish and is capable of withstanding heavy pulling, torsion, and jarring strains without damage to the tools or the fish.

The WCOS has been designed to significantly increase the catch range of the OD of the fish to be caught, compared to the standard overshot. This enables a greater opportunity for a successful fishing operation in a reduced number of trips, thus reducing overall intervention costs for the operator. In addition to the large catch range, the WCOS has the ability to seal across very large extrusion gaps at both standard and high pressure and provide full circulation through the fish, should it be required.

Connections between the Top Sub/Bowl and Extension Sub have been designed to create a seal. This will prevent the connection from washing out should the overshot be required to be flowed through for a long period of time. In order to lock the Top Sub/Extension Sub to the Bowl from backing off during operation, set screws have become standard and will gall the threads should the connection break free.

The operation of all overshots is identical. The exception being that the Series 150 carries a packoff which provides circulation through the fish. First, determine that the overshot is properly assembled and dressed with the proper size grapple. Make up the overshot on the fishing string (normally it is run connected to the bottom of the bumper sub) and run it into the well. As the top of the fish is reached make sure circulation has been established to clear overshot ID of any plugging. Lower the overshot onto the top of the fish with no rotation at first. A 5,000 pound set down weight will be sufficient to engage the grapple. While lowering the overshot over the top of the fish watch for pressure build up, shut off pumps if any pressure build up is noticed. Should any back pressure be noticed, release the back pressure to allow the grapple to engage the fish. By elevating the string it can be determined, if the grapple went over and engaged the fish. If unable to work overshot over top of fish without rotation, then slowly rotate the fishing string to the right and gradually lower the overshot over the fish. Combined rotation and lowering over top of the fish are important to keep the grapple in the release position. This provides the maximum clearance between the grapple and fish. While lowering the overshot over the top of the fish, watch for torque build up and an increase in pump pressure. A pump pressure build up indicates the overshot has gone over the top of the fish thereby reducing the flow area. Stop rotation (continued rotation could dull the wickers of the grapple) enabling the grapple to set. Allow the right hand torque to slack out of the string and then pull on the string by elevating the string to set the grapple.

To release from the fish, bump down, then simultaneously rotate to the right and slowly elevate the fishing string. It is best to have a clean fishing top before running the overshot.

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.

Removal of permanent packers from the well also calls for unique fishing tools and techniques. Several different types of packer retrievers are used depending on packer accessories used during completion. A proven method to retrieve a permanent packer in one trip and list the use of a packer retriever soundly. Its custom-made tungsten carbide faced shoe is dressed to near casing id so it cuts only the slip section of the packer. Adding above the shoe prevents damage to the casing wall. The retrieving assembly with the correctly selected grapple for the packer bore is run below hydraulic jars, colors and a boot basket which collects metal debris cut loose by the shoe. The spear and extension in the assembly is lowered through the packer. Milling over proceeds until the packer is milled free. The spear engages the packer body and it is removed from the well. This standard method of packer retrieval works only if there is no tailpipe below the packer or if a mill out extension has been installed when the packer was running the hole.

If sealed bore extensions are located below the packers without a mill out extension, another type of packer retriever assembly is run for one trip recovery. It incorporates a top bushing that crosses over from a boot basket to the washpipe extension. A j-latch assembly with washpipe connections at the top and bottom and a burning shoe connected to the inside of the j-latch assembly is a man rule: spear extensions, spear stop sub and spear. The assembly is lowered into the well until the spear stabs into the packer manrule.  A gentle pull on the spear confirms that the packer is engaged. J-latches are released, the shoe is lowered, and rotation begins to mill over the packer. With the packer milled free, the string is picked up until the j-latches are secured into the assembly and the packer engaged by the spear is removed from the well.

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.

There are offers of complete line of whipstocks. In addition to the popular whipback, packer-type, hinged open hole whipstocks are also available. Weatherford employees the industry’s widest range of milling tools. Among the most common are junk mills used to mill packers, bridge plugs, cement, perforating guns, drill pipe, tool joints and other obstructions. Junk mills can incorporate a concave, convex or flat bottom depending on the application.

The RedSeal Dual Overshot Packer has been developed to provide a dual seal barrier in surface drilling systems used on jack-up and platform applications.

The RedSeal Dual Overshot Packer has been developed to provide a dual seal barrier in surface drilling systems used on jack-up and platform application. The system provides the operator with a primary and secondary seal system to mitigate potential environmental spills.

The system has been developed with a similar design philosophy to the RedSeal Packer system developed for drilling riser telescopic joints but does not include a facility for refill of the packer online as the seal element is a static seal and not subject to the dynamic motion associated to the RedSeal Packer system. Physically the RedSeal Dual Overshot Packer is shorter than traditional single packer systems allowing the system to be utilised in riser systems where stack-up heights are critical.

RedSeal Dual Overshot Packer can be supplied with a dedicated control system to monitor seal actuating pressure and (upon actuating pressure loss to primary seal element) switch automatically to the secondary seal, thereby minimising any environmental impact.
