Note:

The 3” Tubing End Locator uses a spring-loaded finger to accurately detect the tubing end, ensuring safe and precise well interventions in oil and gas operations.

Executive Summary

The 3” Tubing End Locator is a downhole tool designed to precisely identify the end of 3-inch production tubing during well interventions. Featuring a spring-loaded finger mechanism and a compact profile, it provides a reliable mechanical signal when the tubing bottom is reached.

Its standardized connections allow easy integration into toolstrings, enhancing operational efficiency and safety by preventing over-deployment of tools and reducing the risk of equipment damage. This tool is essential for accurate tubing depth verification in oil and gas well operations.

Detailed Description

The 3” Tubing End Locator is a mechanical downhole tool used to identify the precise end of a 3-inch production tubing string during well intervention operations. It provides a clear physical indication when the tool reaches the bottom of the tubing, helping to ensure accurate placement of equipment inside the well.

Designed specifically for tubing with a 3-inch outer diameter, the tool features a maximum outside diameter of 2.500 inches. This sizing ensures smooth movement within the tubing while maintaining close contact, allowing the tool to operate effectively without the risk of sticking or misalignment. At the core of the design is a spring-loaded finger mechanism that extends outward when the tubing end is reached. This mechanical movement is transmitted to the surface as a tactile response, signaling that the tubing bottom has been contacted.

The tool includes standard threaded connections—such as a 15/16 - 10 UN pin on the top and a 1 - 11 ½ NPT box on the bottom—which makes it compatible with a variety of toolstring configurations. It can be easily incorporated into slickline, wireline, or coiled tubing assemblies without the need for special adapters.

Constructed from durable, corrosion-resistant materials, the tubing end locator is built to perform reliably in downhole environments that involve high pressure, elevated temperature, and exposure to fluids. Its fully mechanical operation ensures a high level of dependability and minimizes the need for maintenance, especially in conditions where electronic systems may not be suitable.

The 3” Tubing End Locator is a practical solution for confirming tubing depth when preparing the well for further intervention.
