Purpose
The RS Pulling tool is used to employ external fishnecks on subsurface devices inside the wellbore. These pulling tools have intermediate cores with medium reach. The tool is used to retrieve subsurface tools where debris might block the latching of a fishneck.
Description
BT RS is made up of 9 components:
1. Fishneck 2. Spring Sleeve 3. Core 4. Core Spring 5. Shear Pin Cover 6. Skirt 7. Dog Spring 8. Dog Washer 9. Dog
Operation
The BT RS has a short core, and in turn is capable of swallowing debris, broken tool, or slickline fragments. Used when there is a need to jar up to shear off a subsurface tool and/or fish when a jar down tool is not desired.
The core may be easily changed out in the field to allow for deeper or shallower reach depending on application.
Precautions
Care should be taken to inspect the dogs, skirt, and fishneck for damage such as metal fatigue, cracking , or deformity of the metal.
