JUS Pulling Tool

Purpose

To run and retrieve subsurface tools.

Description

JUSs are made up of nine components:

1. Fishneck
2. Core Spring
3. Skirt
4. Dog Spring
5. Dog
6. Pawls
7. S Core
8. Shear Pin Sub
9. Shear Pin Cover

Operation

Used when there is a need to jar down to shear off of a subsurface tool and/or fish when a jar up tool is not desired.

The core may be easily changed in the field to allow for a deeper or shallower reach depending on application. The JUS pulling tool is able to be turned into a JDC by simply changing
the fishneck and adding a core cap.

Precautions

Ensure the proper core is installed so as the tool can properly be sheared, the improper core may result in the inability to release the subsurface tool and/or fish.

Care should be taken to inspect the dogs, skirt, and fishneck for damage such as metal . fatigue, cracking , or deformity of the metal.
