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.

Coiled tubing is a continuous, flexible steel pipe widely used in well intervention and maintenance operations, allowing operators to clean, stimulate, log, or deploy tools inside the wellbore without shutting down production. This capability makes coiled tubing an efficient and cost-effective solution to maintain well health and improve productivity.

The 3 1/16” 10M Coiled Tubing Hanger is designed to support larger diameter coiled tubing and heavier tool strings required for more demanding or deeper well operations. The size “3 1/16”” refers to the wellhead bore size that the hanger fits into, while the “10M” indicates its pressure rating of 10,000 psi, meaning it is built to withstand high-pressure environments typically found in advanced well interventions.

This hanger is rated to maintain pressure containment during interventions in high-pressure wells, ensuring safe operations and protecting well integrity. It accommodates coiled tubing sizes ranging from 1 inch up to 1¾ inches outer diameter, which allows the deployment of heavier and more complex downhole tools needed for challenging well conditions. Its rugged construction is engineered to withstand mechanical stresses from heavy tool strings and high pressures without compromising performance.

Designed with flanged connections compatible with API 6B and 6BX standards, the hanger integrates seamlessly with existing wellhead equipment, simplifying installation and maintenance. An important feature of this model is the wireline entry sub, which guides wireline tools into the tubing bore, facilitating additional intervention tasks. The wireline entry sub also provides a secondary annulus seal that prevents fluid or gas leaks and restricts any upward movement of the tubing, enhancing operational safety.

The hanger maintains a secure secondary annulus seal around the tubing, which is critical for isolating pressure zones and protecting against leaks during live well operations. This versatility makes the hanger suitable for various well intervention activities such as well cleanouts, acidizing, logging, and tool deployment, particularly in situations where larger tubing and higher pressures are involved.

The 3 1/16” size strikes a balance between tubing size and wellhead bore capacity. It is larger than smaller hanger sizes, allowing operators to use coiled tubing capable of handling more demanding operational requirements. Its high-pressure rating ensures safe operation in wells where pressures can reach or exceed 10,000 psi, common in deeper or complex reservoirs.

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 6 7/8” to 4 1/2” Tubing Hanger Coupling is a specialized connection used in oil and gas wellhead systems to join a large-diameter casing outlet—6 7/8 inches—with 4 1/2-inch upset production tubing. This configuration is typically applied in high-flow and high-pressure wells where maintaining structural integrity and maximizing production efficiency are critical.

The coupling serves as a transition component within a tubing hanger assembly, allowing the tubing to be securely suspended in the wellhead without the need to rotate the Christmas tree during installation. This is made possible by its union nut design, which permits tightening from the side, simplifying assembly in tight or restricted spaces.

The 4 1/2” end is designed for upset tubing, which features thickened ends to provide stronger threaded connections capable of withstanding axial loads and internal pressure. This enhances the mechanical performance of the joint, reduces the risk of fatigue failure, and helps maintain seal integrity over long service periods. The coupling is also threaded to accept a back pressure valve, an essential feature that provides well control during servicing, installation, or emergency conditions.

To meet a variety of operational needs, the top and bottom threads can be customized according to site or equipment specifications. The coupling is typically manufactured from high-strength, corrosion-resistant materials and in compliance with industry standards such as API 5CT, ensuring it performs reliably under harsh downhole conditions.

Overall, the 6 7/8 x 4 1/2” Tubing Hanger Coupling is chosen for its ability to support larger bore wellhead designs while maintaining compatibility with standard tubing strings. It offers a dependable solution in completions where mechanical strength, pressure containment, and ease of assembly are priorities.

The 3-1/2" WR-SCSSSV FXE is a Ballycatter model safety valve specifically designed for installation in the upper wellbore to provide an emergency shut-off of the production flow path. This valve plays a crucial role in well control by isolating the wellbore during emergency situations such as system failures or damage to surface production control facilities. Its fail-safe design ensures that the valve automatically closes to protect the wellbore and surface equipment whenever a fault occurs.

This safety valve is a flapper-type valve that is both surface controlled and wireline retrievable, allowing operators to easily deploy, operate, and retrieve the valve without extensive well intervention. The valve is installed within a corresponding model Landing Nipple, ensuring precise fit and reliable operation within the tubing string.

The design incorporates a self-equalizing mechanism that balances pressure differentials across the valve, which helps maintain consistent performance even under varying downhole pressures. This self-equalizing feature reduces the risk of valve malfunction due to unexpected pressure changes.

When the valve is in the open position, the sealing surfaces are positioned outside the flow path, ensuring that the fluid can pass freely without obstruction or erosion on the sealing components. This arrangement optimizes flow efficiency and helps extend the valve’s operational life. The flapper itself is made from solid bar stock, providing a strong and durable barrier that can withstand the harsh conditions found in high-pressure well environments.

The valve is rated for working pressures up to 10,000 psi, allowing it to operate reliably under high-pressure well conditions. The 3-1/2" WR-SCSSSV FXE is designed to ensure wellbore isolation in emergency situations, providing a critical safety function in the well control system.
