overshot packer for sale

Stuckey’s Specialty Tools’ releasing and circulation overshot is the strongest available fishing tool for externally engaging, packing off or pulling a catch. Its basic outside construction consists of a top sub, the bowl, and the guide. The internal parts depend on the catch desired. A spiral grapple, spiral grapple control, and type "a" packer can be used or a basket grapple and a mill control packer.

Stuckey’s Specialty Tools’ releasing and circulation overshot requires only right hand rotation during both engaging and releasing operations. No damage or distortion results to the catch or the overshot due to the helically tapered spirals on the inside diameter of the bowl.​

The Retrievable Bridge Plug(RBP) is a high-pressure packer style bridge plug used for multiple selective zone treating and testing operations. The RBP is designed to set in tension or compression, which makes it ideal for shallow applications to test wellhead for deep, high-pressure applications. The plug is designed with a large internal by-pass to prevent swabbing when running and retrieving. The by-pass closes during the setting of the plug and opens prior to releasing the upper slips to equalize pressure when unsetting.

Oil well completion tools include: Subsurface safety valve, wireline retrievable subsurface safety valve, single string production packer, dual strings production packer, ESP packer, mechanical set packer, permanent packer, compensation device, bridge plug, sliding sleeve, nipples etc.

TIANHE 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.

TIANHE 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.

TIANHE Series 150 Releasing and Circulating Overshot can be equipped with a wide range of accessories  to meet a variety of complex fishing environmental.

An extension sub is assembled between the top sub and the bowl.It is used when the upper portion of the fish is damaged or cannot be engaged. This accessory will permit the overshot to be lowered far enough over the fish to ensure secure engagement and pack off. They are available in lengths from 24 to 60 inches. When ordering, specify overshot O.D. Unless otherwise specified Extension Subs will be furnished in a standard 36-inch length.

If the fish is positioned in a washed out section of the hole, it may be difficult to engage the top of the fish using a conventional overshot guide. A wall hook guide can be used to capture the neck of the fish, centralize it, and then properly guide the fish into the bowl.

Oversized Guide properly guides the fish into the overshot when the hole size is considerably larger than the diameter of the fish and the overshot may pass alongside the fish without engaging it. Installation of an oversized guide instead of a standard guide will ensure alignment of the fish with the overshot.

Overshot Mill Extension interiors are faced with ltcoloy to a size that will mill away a flared or jagged fish to enable it to pass up into and be engaged by the Grapple in the Bowl. Mill Extensions are installed between the Bowl and the standard, oversize or wall hook guides.

Overshot Mill Guides are designed to remove badly flared or jagged metal from the top of the fish. Mill Guides are used in place of the Standard or Oversized Guide to trim the fish so it can enter the overshot.

The TIANHE Series 70 Short Catch Overshot is an external fishing tool designed to retrieve tubular fish when the top of the fish is too short to be engaged with other overshot. The Grapple Control is positioned above the Basket Grapple rather than below it to allow the Basket Grapple to occupy the lowest position in the Bowl. This enables the overshot to firmly engage and retrieve a very short fish.

The TIANHE Series 70 Short Catch Overshot assembly consists of a Top Sub, Bowl, Basket Grapple Control, and a Basket Grapple. Although the Series 70 Overshot has no Guide, the components function in the same manner as the standard Series 150 Releasing and Circulating Overshot.

Attach the Overshot to the bottom end of the fishing string and run it into the hole. Series 70 Overshot assembly is rotated to the right and lowered as the fish enters the expandable grapple. With the fish in the Grapple, stop right-hand rotation and exert an upward pull to fully capture the fish.

A sharp downward force (bump) is applied to the Overshot to break the hold of the grapple within the bowl. The Overshot is then rotated to the right while it is slowly elevated to release the Grapple from the fish.

The Series 10 Sucker Rod Overshot is a small, rugged tool designed for engaging and retrieving sucker rods, couplings, and other items from inside tubing strings.

Series 20 Short Catch Sucker Rod Overshots are designed for conditions when sucker rods, couplings, and other portions of a fish are too short for retrieval with a standard overshot.

The Hydraulic Release Overshot was designed to aid in the recovery of a stuck fish in a horizontal drilling application where normal rotation for release is not obtainable.

The Series 150 Releasing and Circulating Overshot consists of three main external parts: a Top Sub, a Bowl, and a Guide. Internal catch and pack-off parts are determined by the diameter of the fish. Each assembly is designed for a maximum catch diameter.

A Series 160 Side Door Overshot is recommended when fishing for cable tools or conductor lines in cased holes. The side door overshot is run in on tubing or drill pipe.

The Packer Retriever Spear is designed to remove drillable full-bore packers from the well casing. With appropriate dressing, the tool can mill through the packer if necessary.

High Pressure Type L Packer Type Casing Patches are designed to engage and seal off a properly prepared casing string. The Casing Patch design leaves the operator with a casing string that has a full-bore internal diameter.

High Pressure Type L Packer Type Casing Patches are designed to engage and seal off a properly prepared casing string. The Casing Patch design leaves the operator with a casing string that has a full-bore internal diameter.

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.

The SAZ-IX Mechanical Production Packer is a retrievable, double-grip compression- or tension-set production packer that can be left in tension, compression, or in a neutral position, and will hold pressure from above or below. A large internal bypass reduces the swabbing effect during run-in and retrieval, and closes when the packer is set. When the packer is released, the bypass opens first, allowing the pressure to equalize before the upper slips are released.

The SAZ-IX also features a patented upper-slip releasing system that reduces the force required to release the packer. A non-directional slip is released first, making it easier to release the other slips.

The SAZ-IX can easily convert to SAZ VI-X with the advantage of being able to set on Electric line or hydraulically- just remove the shear screws and install drag blocks and drag block springs. An On-Off Tool Stinger with a Wireline Plug installed can be attached to the top of this packer. This packer can then be lubricated in the hole and set under pressure. Once set, casing pressure can be bled off, and the tubing with an On-Off Tool Overshot can be run and latched onto the packer. The Wireline Plug can then be removed.

The Series 150 Releasing and Circulating Overshot is an external catch fishing tool designed to retrieve tubular items from the well bore. It is rugged, economical, and easy to use. The Overshot comes with a wide range of available accessories. These fishing tools have proven to be the most versatile and reliable in the field.

The selection of these components is determined by the diameter of the fish to be retrieved. When the fish diameter approaches the maximum catch of the overshot, a spiral grapple is required. This must also be equipped with a spiral grapple control and type A packer. When the diameter is approximately 1/2 inch (or more) under the maximum catch of the overshot, a basket grapple is used. It must be assembled with either a basket grapple control or a mill control packer.

The M.I. Hook-Up Nipple and Back-Off Sub are dual purpose components in the gravel pack assembly. Each serve as the release point for the completion service tool, and as the landing nipple for the Mitchell “L” Packer and Seal Stack Overshot. The standard H.U.N. is offered in 6 ft. and 8 ft. lengths, while the Back-Off Sub is typically 0.5 – 1 ft. in length. Both components have a left-handed square ACME threads machined into the top sub, allowing for a right-hand rotational release. Back-Off Subs are offered in low-alloy steel and 304L SS, and are used in conjunction with the M.I. “L” Isolation Packer. Our M.I. Hook-Up Nipples are offered in a polished 304L SS material and are used with the M.I. Seal Stack Overshot.

The M.I. Type “L” Isolation Packer is a tubing conveyed, mechanically set retrievable packer used in conjunction with gravel pack completions. The “L” Packer features a large internal by-pass that reduces swabbing when running or retrieving. The packer is designed to isolate the lower gravel pack completion by restricting annular flow, forcing all production through the screen. It is equipped with a lower seal extension that stings over our M.I. Hook-Up Nipple and/or Back-Off Sub.

The M.I. Seal Stack Production Overshot can be run under a production or permanent packer, and is designed to seal over our M.I. Hook-Up Nipple. The lower seal extension houses dual opposing molded seal sets that control pressure from above and below the seals. The overshot has a standard 6 ft. bore length to accommodate tubing movement while setting the packer and landing the production tubing at surface.

The AS1-X Double-Grip Packer is a mechanically set retrievable packer used in a wide range of production applications. When utilized in sand control completions, a production overshot is run below the AS1-X Packer as a seal extension. The overshot is landed on the hook-up nipple and the packer is set, either in tension or compression. The AS1-X packer can be run on the bottom of the production tubing, or can be equipped with a stigner and on/off tool for tubing detachment.

The MR-3D Double-Grip Packer is a mechanically set retrievable packer used in completion, stimulation, testing, and production applications. For gravel pack operations, the packer is equipped with a clutch joint/circulating kit and is used as a service tool. In production applications, an overshot is run below the packer as a seal extension and the packer is set with the upper production assembly.

Both the single and dual seal bore packers can be used for single or multiple zone completions. Each packer may be set hydraulically or on wireline, and are available in a variety of seal bore materials and elastomers.

Seal bore packers can be used as a gravel pack base, or in the upper completion assembly. Each packer is supported by a complete line of tubing seal accessories and elastomers.

Seal assemblies are used to land or lock into the polished bore of a packer, creating a leakproof seal. Locator subs are used in installations that require floating seals, allowing for slight tubing movement during expansion and contraction. Snap latch seal assemblies latch into the packer and provide a mechanical indication that the seal assembly is positioned properly in the packer bore. The sanp latch can be removed with a straight pull of 10-12K over tubing weight. The anchor latch assembly latches into the packer bore just like the snap latch, but is removed with 8-10 right-hand rotations. Each of these seal assemblies can be provided with mule shoe guides on bottom, and various length seal units depending on the application.

When sump packers are used in the gravel pack completion design, a seal assembly is required to prevent gravel pack sand from leaking past the packer. In the case of a multizone gravel pack completion, the seal assembly also provides zonal isolation.

The wireline entry guide has an internal bevel on the bottom of the tool that guides wireline or slickline tools back into the tubing. The re-entry guide can be run under various packers, but is most commonly utilized under the lower permanent packer in a gravel pack completion.

The safety joint allows for an emergency release of the tubing string in completions with expected retrieval challenges. The joint is typically used below the completion packer, or in between packers in dual completions. Safety joints are available in straight pull shear release, rotational release, and swivel shear release. These safety joints are keyed so torque through the tool does not load the shear screws.
