The 7-inch Subsurface Controlled Surface Safety Valve (SCSSSV) is a critical safety device designed to automatically shut in a well if uncontrolled flow occurs due to equipment failure or damage. It is installed in the upper part of the well to quickly isolate the producing zone and prevent uncontrolled release of fluids, ensuring well control in emergency situations.

This valve uses a flapper mechanism and is surface-controlled, meaning it can be operated from the surface. It features a self-equalizing design that reduces pressure differences across the valve during opening and closing, which improves reliability and extends valve life. The sealing surfaces are located outside the flow path when the valve is open, reducing wear and protecting key components from erosion.

Because the valve is wireline retrievable, it can be serviced or repaired without pulling the entire tubing string, minimizing downtime and intervention costs. It fits 7-inch tubing and is available with landing nipple seal bores of 5.750", 5.875", or 5.963". It can handle working pressures up to 10,000 psi and offers valve internal diameters of 3.38" and 3.50", allowing operators to balance safety and flow requirements effectively.

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 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.

The 4 ½ x 2 7/8” Tubing Hanger Coupling is a specialized connection component used in oil and gas wellhead systems to join two different sizes of upset tubing—4 ½-inch and 2 7/8-inch. This size combination is commonly selected when there is a need to transition from a wider tubing hanger profile to a smaller production string, without significantly restricting flow or compromising mechanical strength. The slightly larger 2 7/8” production tubing allows for greater internal flow area than smaller alternatives, making this configuration well-suited for completions that aim to support moderate to high production rates.

The coupling is designed with a union nut mechanism, which enables installation without rotating the Christmas tree or disturbing other surface equipment. This simplifies operations, especially in space-limited or sensitive surface environments. Both the top and bottom threads of the coupling can be manufactured to meet specific customer requirements, ensuring compatibility with a range of tubing string designs. Additionally, the coupling is threaded to accommodate a back pressure valve, offering an important safety feature by allowing well pressure to be managed during maintenance or pressure control procedures.

Constructed from high-grade steel and compliant with API standards, the 4 ½ x 2 7/8” Tubing Hanger Coupling offers high durability, corrosion resistance, and the mechanical integrity required for challenging downhole conditions. By supporting a secure, pressure-tight connection between tubing sizes, it plays a key role in maintaining well integrity and operational efficiency in various oil and gas production scenarios.
