The Rebco ROTGS is a shear-down pulling tool specifically engineered for sub-surface devices with internal fishing necks, those in which the fishing neck is machined into the device's inner bore rather than projecting above it. Rather than dogs that snap over an external shoulder, the ROTGS uses a core or prong assembly that enters the bore of the sub-surface device and latches onto the internal fishing neck from the inside. This fundamental difference in engagement geometry makes the ROTGS incompatible with external fishing neck devices and vice versa; the correct pulling tool family must always be matched to the fishing neck type.

Once the ROTGS core is fully inserted and latched inside the internal fishing neck, upward tension retrieves the device. If the device is stuck, a downward jar shears the internal pin, allowing the core to retract and disengage from the internal fishing neck, freeing the ROTGS for retrieval to the surface. The ROTGS is the primary pulling tool for retrieving gas lift valves, dummy valves, and other devices with internal (bore-type) fishing necks, commonly used in side-pocket mandrel and selective completion applications.

The reach for internal fishing neck pulling tools is measured as the distance the core must travel before it latches, a critical factor, since the core must travel far enough into the device bore to reach and engage the internal fishing neck recess. Available in nominal sizes with alloy construction and full accessory support.

How to Order: Specify nominal size and confirm internal fishing neck type before ordering. Contact Rebco for assembly numbers and reach confirmation matched to the specific device being retrieved.

Note: ‘ROT’ is abbreviated for Rebco Oil Tools.
