The P-JD series Pulling Tools are wireline services tools that are used to retrieve ‘jar-to-release’ subsurface devices with external fishing necks. P-JD series pulling tools consist of a fishing neck with a pin thread connection on the upper end, a ‘D’ sub, spring-loaded pulling dogs, a core, a skirt, an emergency release shear pin and two springs, internal and external.

Most P-JD series pulling tools are internally threaded to receive a prong for equalizing operations. Under certain conditions, P-JD series pulling tools can also be used as running tools.

The P-JD series pulling tool nomenclature is as follows: the first letter (J) indicated the pulling tool series. The second letter (D) indicated that the downward jarring is required for safety release. The third letter indicated the core length: Any letter or number following the first letters indicates a variation of one or more of the following specifications: maximum OD, core length, pin thread connection.
