GS Pulling Tool

Technical Description and Specifications

The GS Pulling Tool is a specialized internal pulling tool designed to engage and retrieve downhole equipment equipped with an internal fish neck. Unlike the J-series (JDC/JUC), which grips the outside of a tool, the GS tool features dogs that expand into an internal profile, making it the standard choice for pulling large-bore equipment like plugs, packers, and subsurface safety valves.

Key Technical Specifications and Operation

• Function: To retrieve downhole tools that have an internal fishing neck profile. It is a shear-down-to-release tool, meaning that if the fish cannot be pulled, the operator jars downward to shear the pin and retract the dogs.

• Mechanism: The tool is equipped with a set of robust latching dogs. As the tool enters the internal fish neck of the target device, the dogs are compressed and then spring outward into the locking groove of the fish.

• Shear-Down Release: A critical safety feature of the GS tool is its release mechanism. If the tool becomes stuck, a downward impact shears a pin, allowing the core to move and the dogs to retract into the tool body, ensuring the tool string can be safely recovered.

• Standard Reach: The GS is designed with a “short core” compared to its counterpart, the GR tool. This ensures it is compatible with standard internal fish neck depths found in most flow control devices.

• Operational Advantage: Because it engages internally, the GS tool can be used to pull tools with a larger diameter than the pulling tool itself, providing a high-strength connection for heavy-duty retrieval.

Customization and Materials

• Core Options: While the GS is the standard shear-down version, it can be converted to a GR (Shear-Up) configuration by changing the internal core and spring arrangement for specific operational needs.

• Material: Constructed from high-strength alloy steel. For wells with high concentrations of $H_2S$ or $CO_2$, NACE MR0175 compliant materials and specialized coatings are available.

• Dog Configurations: Various dog profiles are available to match different manufacturer-specific internal fish neck designs.
