A Collet Pulling tool is a wireline service tool used for retrieving subsurface devices with external fishnecks. These tools can be jar down or jar up to shear which can be altered back and forth based on how these are assembled.
The Collet Pulling Tool can be ran as a jar up CRU or jar down CRD and can be changed back and forth just like a Camco JUC or JDC.
When the collet slides over the fishneck to be retrieved it surrounds the fishneck 360 degrees so that even damaged fishnecks can be pulled. This tool can withstand much more excessive jarring than conventional pulling tools.
Avoid placing vise jaws or pipe wrenches near windows on skirt. Remove the set screws before disassembly when servicing check for cracks and damaged parts.
Ensure when Running a CRD that the tool has sufficient distance for skirt to travel downwards to allow the tool to be sheared.
