The Rebco JUC is a shear-up, short-reach pulling tool for external fishing necks. Its operational sequence mirrors that of the JDC: dogs snap over the fishing neck as the tool is lowered, and upward tension retrieves the device, but the critical difference lies in the release direction: rather than jarring down to release, the JUC releases by jarring upward. This makes the JUC the correct choice for sub-surface devices installed in completions or positions where a downward jar could risk damaging equipment below, driving the device further into a restriction, or creating an unsafe condition.

The shear-up release also provides a distinct operational advantage when retrieving devices in wells with heavy fluid columns or high upward wellbore pressure, conditions that would make a downward jar difficult to deliver with sufficient force. In these situations, the upward jar needed to release the JUC is assisted by the wellbore pressure, making the release more reliable. The short-reach core suits fishing necks located near the top of the sub-surface device assembly.

Available in nominal sizes from 1¼" to 4", with alloy construction throughout.

How to Order: Available in assembly numbers from the JUC series. Specify the nominal size and confirm that the short reach is appropriate for the target fishing neck depth. Contact Rebco for specific assembly numbers.
