Tubing End Locator

Re-setting locating device

Download Spec Sheet

The Oilenco tubing end locator is an automatically re-setting locator device which permits the operator to make unlimited attempts at verifying the end of the tubing without having to recover the tools to surface for redress.

The 45 degree shoulders of the locator keys provide resistance to the passage of the toolstring which can be observed as an over-pull at surface by the winch operator. The value of this over-pull can be adjusted if desired by altering the setup of the latch trigger to meet downhole parameters.


  • Automatically resets, no requirement for redress between tagging attempts
  • Can be used to tag both top and bottom of broken tubing
  • Collapse force of the locator keys can be adjusted to reduce the maximum required over-pull

Once the resistance value is overcome the locator keys collapse and the toolstring passes back inside the end of the tubing. It is also possible to land the tubing end locator off on a lower break provided that the tool weight below the spang jar does not exceed the collapse force of the keys in the downward direction. This can be repeated as many times as necessary to verify consistent depths are being observed.


The tubing end locator can be used as a tool to verify the end of the tubing without having to recover tools, as well as a depth correlation tool.
