The Rebco JDC is a shear-down, short-reach pulling tool designed to retrieve sub-surface devices with external fishing necks in applications where the fishing neck is positioned close to the top of the device, meaning a shorter reach is both sufficient and preferred. The JDC engages the external fishing neck by allowing its dogs to snap over and behind the fishing neck shoulder as the tool is lowered over the device. Once latched, upward tension on the wireline lifts the device from its set position. If the device is stuck and cannot be freed, a firm downward jar stroke shears the internal shear pin, collapsing the dogs inward and releasing the JDC from the fishing neck, allowing the tool string to be retrieved without the device.

The short-reach configuration of the JDC means the distance between the bottom of the core and the dog-engaging surface is intentionally minimized, making the JDC the correct choice when the gap between the top of the landing nipple and the fishing neck is small, or when working in completions with closely spaced nipples where a long-reach tool risks engaging the wrong fishing neck. Changing the core is all that is required to obtain a different reach within the same nominal size; no full tool replacement is necessary.

Available in nominal sizes 1¼" through 4", engaging fishing neck ODs from 0.875" to 3.125". Alloy construction throughout.

How to Order: Available in assembly numbers from 400703021250 (1¼") to 400703024000 (4"). Specify the nominal size and confirm the reach against the device's fishing neck dimensions for the retrieved device. Pinning Tool Assembly and Core Wrench are ordered separately by nominal size
