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 4 1/16” 10M Coiled Tubing Hanger is engineered to provide reliable mechanical support and pressure containment for coiled tubing strings used in demanding oil and gas well intervention operations. Specifically designed to accommodate coiled tubing sizes up to 3 1/2” outer diameter, this hanger is rated for high-pressure applications up to 10,000 psi (10M), making it suitable for wells with challenging downhole conditions and high-pressure requirements.

Constructed with robust materials and precision-engineered to meet API 6B and 6BX standards, the hanger ensures secure connection to wellhead equipment through flanged interfaces, enabling seamless integration into existing well infrastructure. The design incorporates a wireline entry sub that guides wireline tools into the tubing bore and provides a secondary annulus seal. This feature not only facilitates the safe deployment of wireline tools but also restricts any upward movement of the coiled tubing, maintaining tubing position and well control during operations.

This coiled tubing hanger supports a range of intervention tasks, including well cleanouts, stimulations, logging, and workover activities, by securely suspending the tubing and maintaining pressure integrity at the wellhead. The ability to reliably seal the annulus while supporting heavy-duty tool strings helps reduce operational risks, prevents fluid leaks, and minimizes well downtime. Its capacity to handle larger tubing sizes and high pressures makes the 4 1/16” 10M hanger especially valuable in complex wells where robust mechanical support and dependable sealing are critical for safe and efficient well intervention.

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.
