Mechanical Tubing End/Nipple Locator

The WellEnTech Mechanical Tubing End/Nipple Locator provides a means of locating the end of a tubing string or nipples within a wellbore. The spring loaded Dogs provide a positive indication that the tubing end or nipple has been located. For added security, the tool has a shear release mechanism to enable the dogs to release should any well problems occur.

Operation

The WellEnTech Hydraulic Tubing End/Nipple Locator is deployed as part of a tool string where a tubing nipple or tubing end needs to be located for depth correlation. The tool is run in hole and is generally run past the assumed position of the nipple or tubing end. As the tool string is manipulated both upwards and downwards through the nipple profile an increased pull push load will be witnessed at surface, verifying the position of the nipple. Likewise the tubing end can be correlated when an over pull is witnessed as the tool moves back into the tubing end. If for any reason, the tool becomes stuck in hole, a predetermined over pull will result in the shear screws shearing and de-supporting the dogs. The tool can then be retrieved to surface.
