The 2 9/16” 10M Coiled Tubing Hanger is used to suspend coiled tubing during well intervention and workover operations in high-pressure environments. It is rated for a working pressure of up to 10,000 psi and is typically installed as part of the wellhead assembly to maintain well control during live operations.

Coiled tubing (CT) is a continuous length of small-diameter steel pipe deployed into a well without the need for threaded connections. It allows operators to perform various tasks—such as cleaning out debris, stimulating production zones, or running diagnostic tools—without removing existing production tubing. This makes CT a common method for non-invasive well maintenance.

The hanger supports coiled tubing sizes from 1” to 1¾” outer diameter. It connects to the surface system using standard API 6B or 6BX flanges. A wireline entry sub is included, which serves two functions: it guides wireline tools into the tubing and provides a secondary annular seal to help control pressure and prevent tubing movement.

This component is part of the broader coiled tubing unit and is required to safely manage tubing and tool access while maintaining pressure integrity. It is typically used in wells where continuous intervention work is needed without shutting in the well, especially in high-pressure or deeper formations.

In oil and gas well operations, the 2 ½” Tubing End Locator plays a critical role in confirming the exact depth at which production tubing terminates within the wellbore. Accurately identifying the tubing endpoint is essential during various well intervention activities, including maintenance, workovers, and the installation or retrieval of downhole tools and equipment.

During operations such as setting packers, deploying plugs, running logging tools, or performing fishing jobs to recover stuck equipment, precise knowledge of tubing length ensures that tools are positioned correctly. This prevents accidental over-pumping or tool deployment beyond the tubing into the open hole section of the well, where damage to equipment or tool loss can occur.

The 2 ½” Tubing End Locator is designed specifically to fit tubing with an outer diameter of approximately 2 ½ inches. It features a compact maximum outside diameter of around 1.750 inches, allowing it to pass easily within the tubing without causing obstruction. The tool employs a spring-loaded finger mechanism that activates mechanically upon reaching the tubing bottom. This signal does not rely on electronic sensors or depth measurement devices, making the tool highly reliable even in harsh downhole environments where electronics may be compromised by pressure, temperature, or fluid conditions.

Standardized threaded connections on the tool—typically a 15/16 - 10 UN pin on the top and a 1 - 11 1/2 NPT box on the bottom—enable it to be seamlessly integrated into a wide range of intervention toolstrings. These common connection types ensure compatibility with existing downhole equipment and facilitate quick assembly and deployment.

Manufactured from high-strength alloy steel or similar materials, the tubing end locator is built to withstand typical downhole conditions, including high pressure, elevated temperatures, and corrosive fluids commonly found in oil and gas wells. Its purely mechanical design minimizes maintenance requirements and reduces the risk of failure compared to electronic alternatives.

This tool is particularly valuable in wells where tubing length may have changed due to wear, repairs, or previous interventions, offering an essential measure of control and confidence in complex well environments.

Available sizes: 2 3/8”, 2 7/8”, 3 1/2”, 4”, 4 1/2”, 5”, 5 1/2'” and 7”.

The 4-inch Surface-Controlled Subsurface Safety Valve (SCSSV) is designed for installation in wells with 4-inch production tubing and serves as a critical safety device to shut in the well during uncontrolled flow events caused by equipment failure or loss of surface hydraulic control pressure. The valve operates via a hydraulically actuated flapper mechanism that remains open under normal operating pressure but closes automatically if the hydraulic signal is lost. This fail-safe design isolates the wellbore, preventing unintended release of hydrocarbons and protecting both personnel and the environment.

The flapper mechanism is simple and robust, minimizing moving parts in the flow path and reducing potential points of failure. When open, the sealing surfaces are positioned out of the fluid flow path, which helps maintain smooth production flow and reduces wear on sealing components. The valve’s hydraulic actuation allows reliable operation under varying pressure and flow conditions commonly encountered in oil and gas wells.

The valve is wireline retrievable, which means it can be removed, serviced, or replaced using wireline tools without the need to pull the entire tubing string from the well. This capability significantly reduces well intervention time and associated costs while allowing maintenance or upgrades to be performed efficiently.

This SCSSV fits standard landing nipples with a seal bore of 3.313 inches and is rated for working pressures up to 5,000 psi. Its internal valve diameter is 1.75 inches, providing an appropriate balance between flow capacity and structural integrity for wells with moderate to high flow rates. The 4-inch tubing size is common in many oil and gas production wells, making this valve size versatile across different field conditions.

This size is commonly applied in production wells where 4-inch tubing is standard, supporting reliable well control and efficient maintenance. Its hydraulic surface control and simple flapper design contribute to dependable operation under varying well conditions.

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.
