GU Adapter


Used most commonly for retrieving down hole components, that require downward movement or jarring during pulling sequence.


The GR Pulling Tool is assembled by attaching a GU Adapter sub to the top of a GS Pulling Tool. The shear pin must be removed from the shear down GS Pulling Tool and a shear pin installed in the GU Adapter sub. Shearing the GR pulling tool is accomplished by upward jarring. Once the pin is sheared in the GU adapter sub, the cylinder on the GS is forced upward by the core spring tension releasing the dogs to the retracted position. Extended core lengths are optional for GS portion of the pulling tool for retrieving equipment with an inner locking sleeve.
