A GS Pulling Tool is designed to engage and retrieve subsurface devices with internal fishing necks. It features a shear pin mechanism that allows the tool to be jarred down to release from the device, ensuring efficient and secure retrieval. The GS Pulling Tool is available in various sizes to accommodate different operational needs and is built with a robust design to withstand the demanding conditions of downhole environments. Its versatility is enhanced by the ability to configure it with additional adapters, such as the GU Adapter, to switch between jar up and jar down operations.
