The Rebco JDS is the medium-reach counterpart to the JDC, sharing the same shear-down release mechanism and external fishing neck engagement design, but with a longer core that positions the dog-engaging surface farther below the bottom of the tool body. This additional reach is necessary when the sub-surface device's fishing neck sits deeper below the top of the landing nipple or sub-surface assembly, such as when the device has been set with an extended packing mandrel below the fishing neck, or when the completion geometry results in the fishing neck being recessed further than a short-reach tool can access.

The JDS is otherwise operationally identical to the JDC: dogs snap over the external fishing neck on the trip down, upward tension retrieves the device, and a downward jar shears the pin and releases the tool if the device is stuck. As with the JDC, changing the core is all that is required to switch between short- and medium-reach within the same nominal size.

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 400703141250 (1¼") to 400703144000 (4"). Specify nominal size. Confirm medium reach is required by measuring or referencing the fishing neck depth on the device to be retrieved before deployment.
