The 2” Tubing End Locator is a mechanical downhole tool used to determine the physical end of production tubing during well intervention or maintenance activities. It is a critical component in operations where it is necessary to confirm tubing length or avoid tool deployment beyond the tubing’s bottom, such as during setting packers, logging, or fishing operations.

In a typical well setup, production tubing does not always terminate at a predictable or recorded depth. The tubing end locator provides a reliable way to identify the true end of the tubing string by using a spring-loaded finger mechanism that reacts upon reaching the tubing’s bottom. This reaction is detectable at the surface, providing the operator with a clear and immediate indication without relying solely on depth readings or assumptions.

This specific model is intended for tubing sizes ranging from 2" to 2-1/2" outer diameter. It is designed with a maximum tool O.D. of 1.750", which ensures clearance inside the tubing, and includes a 1.375" fishing neck, a standardized feature that allows the tool to be retrieved if necessary using conventional pulling tools.

Threading is provided on both ends for integration into tool strings: a 15/16 - 10 UN pin connection on top and a 1 - 11.1/2 NPT box connection at the bottom. This allows the locator to be run inline with other mechanical or wireline-conveyed tools. These standard thread forms ensure compatibility with widely used downhole equipment and deployment systems.

Constructed from high-strength alloy steel, the tool is designed to withstand the mechanical stress, temperature variations, and chemical exposure typical in oil and gas well environments. While not a pressure-control device, its materials and design are selected to perform reliably under downhole pressure conditions encountered during standard intervention work.

The 2” Tubing End Locator provides a mechanical means of depth verification that does not rely on electronics, sensors, or depth counters. It is a simple, durable, and effective tool for reducing uncertainty and improving operational safety in the wellbore.

The 6 5/16” to 2 1/2” Tubing Hanger Coupling is a specially made part used in oil and gas wells to connect a large casing opening to smaller tubing—typically 6 5/16 inches—to a smaller 2 1/2-inch upset production tubing. This size combination is often selected for well designs that require a broader casing interface for flow management, safety equipment, or well control hardware, while maintaining a slimmer production string for specific flow requirements or structural considerations.

This coupling is manufactured with upset-end compatibility, meaning it is suited for tubing that has thickened ends designed to strengthen threaded connections. This feature improves mechanical reliability and helps the connection withstand downhole pressure, tensile loads, and thermal cycling. The union nut design allows the coupling to be installed by tightening the nut without rotating the upper wellhead assembly, which is particularly useful in space-constrained or high-integrity environments.

To accommodate a range of operational needs, the coupling can be threaded on both ends to suit different tubing or spool designs and is compatible with back pressure valves—providing added safety during pressure control, intervention, or servicing. Built in accordance with API specifications and from high-strength materials, the coupling is designed to operate reliably in demanding conditions, including high-pressure wells and corrosive environments.

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 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.

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

The 4 1/2" Surface-Controlled Subsurface Safety Valve (SCSSSV) is selected for wells that require dependable emergency shut-in capability while handling moderate to high flow rates. This size is appropriate when production demands a larger flow area to minimize pressure drop and maintain efficient fluid flow. It provides essential well control by automatically isolating the wellbore in cases of equipment failure or loss of surface control pressure, ensuring safety without compromising production efficiency.

This SCSSSV is designed for compatibility with 4 1/2" (114.3 mm) tubing and is available with landing nipple seal bores of 3.437", 3.688", or 3.813". It supports working pressures up to 5,000 psi and comes with internal valve bore options of 1.75", 1.87", and 2.12"—allowing operators to balance flow capacity with safety requirements.

The self-equalizing mechanism minimizes differential pressure across the valve during opening, improving control and reducing mechanical wear. With sealing surfaces located outside the flow path in the open position, the valve is less susceptible to erosion and damage during production.

Constructed with a robust flapper made from bar stock, the valve features a flapper-type mechanism that reliably closes to prevent uncontrolled flow. The valve is wireline retrievable, which allows for extraction and servicing of major components without removing the entire tubing string. This capability reduces intervention time and operational costs, contributing to overall well uptime and efficiency.
