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.

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.

In the early 1930s, the consequences of the stock market crash prompted S.R. Bowen to consider starting a company in Houston, where oil exploration and drilling was accelerating. In the early spring of 1934, his son Walter and a friend formed Bowen Company of Texas.

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.

If a stop ring is needed and the grappledoes not have a built-in stop, a stop ring can be run above the grapple, in the area between the Top Sub pin and the Grapple.

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.

Special Grapples:Nitraloy grapples may be available from some vendors. It is available only in the most popular sizes and is not commonly used on standard pipe.

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.

New coarse threads have been introduced at the connection between the top sub and bowl to allow for quick assembly while maximizing the torsion and tensile strength.

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.

Oil prices have rallied to multiyear highs on surging demand, tight supply, and the crunch on natural gas. Brent crude futures, the benchmark in global energy markets, hit a three-year high of above $86 a barrel in late October. Futures for West Texas Intermediate (WTI), the U.S. benchmark, surpassed $85 a barrel, the highest since October 2014. We analyze the dynamics of the crude market below.

The key question is whether the rally in oil prices can be sustained. Rising natural gas prices and a cold winter could lead to a further increase in prices. However, this rally has extended beyond market fundamentals. Oil markets are historically volatile, and should crude overshoot current levels, a correction would likely be sharp. From a trading perspective, this isn’t the right time or price to take long positions, in our view. That is partly because many sell-side commodity traders are revising their forecast to $100 a barrel, while physical markets aren’t showing a level of tightness consistent with that.

It’s true that in the United States, inventories of crude and petroleum products have fallen below the five-year average. This indicator, however, is misleading due to the jump in inventories during the Covid-19 pandemic. It is fair to say that inventory levels are now close to those of late 2018 and early 2019. During that period, oil prices were volatile, between $40–$70 a barrel.

Our fair value model for oil shows $69 a barrel for WTI. But prices have already overshot this level, showing the steepest increase since we started our fair value analysis. In our view, for oil to continue to trade at more than $80 a barrel, inventories will need to decline in January and February — the seasonally weakest months of the year. If inventories do not decline during this winter, we believe prices of WTI in the futures market will likely converge to our fair value to reflect existing supply-demand conditions.

Why are prices overshooting? We believe it is because of concerns about shortages as the northern hemisphere heads into winter. It has little to do with oil’s physical markets. Prices of other energy sources, natural gas, and coal, have spiked due to low inventories, rising demand from China, and worries about a cold winter. The surge in global natural gas and coal prices has also lifted oil futures, partly because of expectations about rising demand for cheaper oil. There are also supply shortages for light, sweet crude in Europe.

Demand for light, sweet crude is high because of refinery dynamics, including its lower refining cost. Refineries are heavy users of energy. Complex and profitable refineries process high sulfur oil (cheaper oil) at hydrocrackers that use hydrogen generated from natural gas. Higher gas prices in Europe and Asia have raised the operational cost of these hydrocrackers. As a result, crude inventories remain low in Cushing, Oklahoma, a storage hub and delivery point for the NYMEX WTI futures contract, while more barrels are being diverted to fill the new Capline pipeline in Illinois. These dynamics have contributed to the low price spread between Brent and WTI crude.

Demand, however, remains low for heavier, sour crude. There are still unsold barrels of this oil in the Middle East, including the Upper Zakum grade crude from the United Arab Emirates. West African grades are also having a tough time as freight costs increase. In addition, China’s limited oil import quotas are having a troubling impact on oil from Angola.

The rally in the futures market has extended beyond the fundamentals of the physical markets, in our view. The Organization of Petroleum Exporting Countries and its partners (OPEC+), a 23-nation grouping led by Saudi Arabia and Russia, are sellers in the real market. They are more concerned about the physical market for oil versus the financial markets.

A colder winter could send natural gas and coal prices soaring, and this could impact crude prices as companies and manufacturers further switch to using oil. However, because we rely on physical markets, and not necessarily the weather, to forecast the trend in oil markets, we believe it is time to question the current rally. We have a neutral view on oil prices over the short term and a bearish view over the long term.

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.
