The 4 ½ x 2 7/8” Tubing Hanger Coupling is a specialized connection component used in oil and gas wellhead systems to join two different sizes of upset tubing—4 ½-inch and 2 7/8-inch. This size combination is commonly selected when there is a need to transition from a wider tubing hanger profile to a smaller production string, without significantly restricting flow or compromising mechanical strength. The slightly larger 2 7/8” production tubing allows for greater internal flow area than smaller alternatives, making this configuration well-suited for completions that aim to support moderate to high production rates.

The coupling is designed with a union nut mechanism, which enables installation without rotating the Christmas tree or disturbing other surface equipment. This simplifies operations, especially in space-limited or sensitive surface environments. Both the top and bottom threads of the coupling can be manufactured to meet specific customer requirements, ensuring compatibility with a range of tubing string designs. Additionally, the coupling is threaded to accommodate a back pressure valve, offering an important safety feature by allowing well pressure to be managed during maintenance or pressure control procedures.

Constructed from high-grade steel and compliant with API standards, the 4 ½ x 2 7/8” Tubing Hanger Coupling offers high durability, corrosion resistance, and the mechanical integrity required for challenging downhole conditions. By supporting a secure, pressure-tight connection between tubing sizes, it plays a key role in maintaining well integrity and operational efficiency in various oil and gas production scenarios.

The 2 9/16” 5M Coiled Tubing Hanger is a tool designed to securely hold coiled tubing in place during well operations where pressure can be high—up to 5,000 psi. It is built to support heavy coiled tubing and the equipment attached to it when performing tasks deep inside the well.

This hanger works with coiled tubing sizes of 1 inch, 1¼ inches, 1½ inches, and 1¾ inches in outside diameter, making it suitable for a range of tubing types used in different well operations. It connects to the wellhead using standard flanged connections.

A special feature of this hanger is its wireline entry sub. This part acts as an extra seal around the tubing to maintain pressure control in the well while allowing wireline tools to pass safely through the tubing. The wireline entry also prevents the tubing from moving upwards during operations, which helps protect the equipment and maintain well safety.

The hanger is powered by electricity, which supports reliable operation in the field. Overall, the 2 9/16” 5M Coiled Tubing Hanger helps keep the tubing stable, maintain well pressure, and allow tool access during important tasks like cleaning the well, stimulating production, or running diagnostic tools.

The 3” Tubing End Locator is a mechanical downhole tool used to identify the precise end of a 3-inch production tubing string during well intervention operations. It provides a clear physical indication when the tool reaches the bottom of the tubing, helping to ensure accurate placement of equipment inside the well.

Designed specifically for tubing with a 3-inch outer diameter, the tool features a maximum outside diameter of 2.500 inches. This sizing ensures smooth movement within the tubing while maintaining close contact, allowing the tool to operate effectively without the risk of sticking or misalignment. At the core of the design is a spring-loaded finger mechanism that extends outward when the tubing end is reached. This mechanical movement is transmitted to the surface as a tactile response, signaling that the tubing bottom has been contacted.

The tool includes standard threaded connections—such as a 15/16 - 10 UN pin on the top and a 1 - 11 ½ NPT box on the bottom—which makes it compatible with a variety of toolstring configurations. It can be easily incorporated into slickline, wireline, or coiled tubing assemblies without the need for special adapters.

Constructed from durable, corrosion-resistant materials, the tubing end locator is built to perform reliably in downhole environments that involve high pressure, elevated temperature, and exposure to fluids. Its fully mechanical operation ensures a high level of dependability and minimizes the need for maintenance, especially in conditions where electronic systems may not be suitable.

The 3” Tubing End Locator is a practical solution for confirming tubing depth when preparing the well for further intervention.

The 6 5/16” to 2 1/2” Tubing Hanger Coupling is a specially made part used in oil and gas wells to connect a large casing opening to smaller tubing—typically 6 5/16 inches—to a smaller 2 1/2-inch upset production tubing. This size combination is often selected for well designs that require a broader casing interface for flow management, safety equipment, or well control hardware, while maintaining a slimmer production string for specific flow requirements or structural considerations.

This coupling is manufactured with upset-end compatibility, meaning it is suited for tubing that has thickened ends designed to strengthen threaded connections. This feature improves mechanical reliability and helps the connection withstand downhole pressure, tensile loads, and thermal cycling. The union nut design allows the coupling to be installed by tightening the nut without rotating the upper wellhead assembly, which is particularly useful in space-constrained or high-integrity environments.

To accommodate a range of operational needs, the coupling can be threaded on both ends to suit different tubing or spool designs and is compatible with back pressure valves—providing added safety during pressure control, intervention, or servicing. Built in accordance with API specifications and from high-strength materials, the coupling is designed to operate reliably in demanding conditions, including high-pressure wells and corrosive environments.

The Wireline Spear is a downhole tool used in oil and gas wells to retrieve lost, broken, or compacted wireline that cannot be engaged with a standard two-prong wireline grab. It is designed for fishing operations where the wireline has become badly balled up or tightly compacted, situations where conventional pronged grabs are ineffective.

The tool is deployed on a wireline and guided down the wellbore under its own weight. Its central mandrel is surrounded by upward-pointing barbs or slips that penetrate and anchor into the wireline. When engaged, these barbs provide a secure grip on the wire, allowing the tool and wire to be retrieved to the surface.

The Wireline Spear is designed for maximum penetration into tightly balled or compacted wire. Its barbs ensure engagement even when the wire is severely entangled. Because the Wireline Spear is effectively non-releasable, it is typically run with a disconnect arrangement above the tool. This allows the assembly to be released if the wire cannot be recovered fully, preventing the tool from becoming stuck in the wellbore.

The tool is available in sizes from 1.5” to 3.5”, with a maximum outside diameter of 1.500” to 3.500” and a fishing neck O.D. of 1.375” to 2.312”. It connects to the wireline through a top connection ranging from 15/16 – 10 UN to 1-1/16 – 10 UN and can retrieve wire diameters from 0.50” to 3.50”.

The Wireline Spear is constructed from steel to withstand downhole mechanical stresses and pressures. Its design includes a central mandrel with upward-pointing barbs that secure tightly compacted or balled-up wireline. The tool’s compact dimensions and engagement mechanism allow it to retrieve wireline that cannot be captured by standard pronged grabs, and it is generally run with a disconnect arrangement above the tool to allow release if the wire cannot be recovered.
