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 5" SCSSSV (Surface-Controlled Subsurface Safety Valve) is used to shut in a well if there\'s a sudden loss of control—such as equipment failure or surface damage. Installed in the upper wellbore, it acts as a critical safety barrier, closing automatically if surface control pressure is lost. This helps protect people, equipment, and the reservoir from uncontrolled flow.

This valve is designed for 5" (127 mm) tubing and fits a 4.125" landing nipple. It’s rated for working pressures up to 5,000 psi and has a 2.38" internal bore, making it well-suited for high-rate production wells. The valve includes a self-equalizing feature that helps reduce pressure differences across the flapper during reopening, supporting smoother restarts and lowering mechanical stress.

Because it’s wireline-retrievable, the internal components can be serviced or replaced without pulling the tubing—saving time and reducing intervention costs. The flapper is machined from solid bar stock for durability, and the sealing surfaces are positioned out of the flow path when open, helping extend the life of the valve by reducing wear.

This size is typically chosen when both high flow capacity and reliable emergency shut-in protection are required.

The 4” Tubing End Locator is designed specifically for use with larger production tubing strings common in wells that require greater flow capacity or enhanced mechanical strength. This size is typically found in wells with higher production rates or more demanding operational requirements, where accurate depth confirmation becomes even more critical.

This model is specifically sized for 4-inch outer diameter tubing, featuring a maximum outside diameter that fits comfortably within the tubing’s internal dimensions. This sizing ensures that the locator can move smoothly without obstruction while maintaining effective contact to detect the tubing end. The core mechanism involves a spring-loaded finger that extends outward upon contacting the tubing bottom. This movement translates into a tactile signal felt at the surface, eliminating the need for complex electronic systems and reducing the risk of failure in harsh downhole environments.

Equipped with standardized threaded connections—commonly a 1-9/16 - 10 UN pin on the top and a 1 - 11 ½ NPT box on the bottom—the tool integrates easily into typical slickline, wireline, or coiled tubing toolstrings. The fully mechanical design enhances reliability, making it well-suited for use in conditions of high pressure, elevated temperatures, and corrosive fluids often found in oil and gas wells.

The 4” Tubing End Locator is especially valuable in wells with larger tubing sizes where accurate depth confirmation is critical to avoid operational errors. By providing a straightforward and dependable method to locate the tubing end, it supports safe and efficient well intervention, helping to reduce downtime and operational risks.
