764W BO Selective Shifting Tool

Product No. 764W

Model: BO Selective Shifting Tool

Description/Application

The Model BO selective positioning tools are used to move the inner sleeve to its open or closed position in Sliding Sleeve.

The positioning tool engages the recess in the upper (or lower) end of the inner sleeve to permit the sleeve to be shifted by a jarring action. The tool is designed to release itself only after the sleeve reaches its fully open or closed position. This automatic-releasing feature incorporates a releasing profile on the key itself that acts to compress the key spring and release the positioning tool. A shear pin is an added feature designed to release the tool in the event well conditions make it impossible to shift the sleeve.

A set of positive keys is available for this tool to permit upward movement of the inner sleeve of one among several Sliding Side-Door circulating devices in one wellbore. These keys do not have a releasing profile. The positioning tool pin must be sheared to release.

The Model BO selective positioning tools are designed to selectively position Sliding Side-Door inner sleeves only to the down position. These tools are designed so that one sleeve can be shifted to the down position at any level in the tubing string without shifting any other sleeve.

This positioning tool is designed with dogs that serve to locate the proper Sliding Side-Door circulating device and release the spring-loaded keys to engage the profile in the inner sleeve. The tool is designed to release itself only after the sleeve reaches the full-down position. This automatic release feature incorporates a releasing profile on the key that acts to compress the key spring and release the positioning tool. The tool can then be raised to the next Sliding Side-Door circulating device to position its sleeve down or return to the surface.
