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.
