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 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 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 4 ½” x 2 3/8” tubing hanger coupling is a specialized downhole component designed to connect two different sizes of upset tubing within a wellhead assembly. Upset tubing refers to tubing that has thicker, reinforced sections at the ends—called “upsets”—which strengthen the threaded connections and help withstand the mechanical stresses and high pressures encountered during well operations. This coupling provides a secure and pressure-tight transition between a larger 4 ½-inch tubing hanger and a smaller 2 3/8-inch production tubing string, enabling effective management of wellbore fluids and maintaining pressure containment.

Engineered to integrate seamlessly with tubing hanger spools, wrap-around tubing hangers (PTHSW), and ‘PTHS’-type tubing spools, this coupling forms part of a modular wellhead completion system. Its union nut design allows installation by screwing the coupling in place without rotating the Christmas tree, simplifying assembly and reducing the risk of damage during installation.

Both the top and bottom ends of the coupling are threaded to customer specifications, offering flexibility for various well configurations and allowing the installation of back pressure valves to maintain well control during operations. Manufactured to API standards and constructed from high-grade materials, the coupling delivers durability and reliable performance in demanding downhole environments characterized by high pressure, temperature, and corrosive fluids.

By facilitating a smooth and strong size transition between different tubing strings, the 4 ½” x 2 3/8” tubing hanger coupling supports well integrity, operational efficiency, and safety throughout oil and gas production.
