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.

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.
