The RJ Pulling tool is used to employ external fishnecks on subsurface devices inside the wellbore. This pulling tool has a short core with long reach.
When the tool is engaged on external fishnecks, upward jarring action shears the pin releasing the spring loadeddogs which allowsthe tool to be retrieved.
The BT RJ 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.
Care should be taken to inspect the dogs, skirt, and fishneck for damage such as metal fatigue, cracking , or deformity of the metal.
