Drilling Jar System

Drilling Further. Drilling Faster.

The Rubicon Drilling Jar System utilizes unique hydraulic valves and spacing for optimal jarring force to tackle multiple jarring events. Its all-in-one design can be assembled as mechanical, hydraulic mechanical or double-acting hydraulic mechanical. It features a mechanical latch system that locks the jar in place until the settings are exceeded by pulling or slacking the drill string when stuck. Once released, it enters into a hydraulic delay that uses the drill string’s energy while delaying the release, creating energy to jar the drill string.

Making it better

The Rubicon Drilling Jar System prevents loss of high cost BHAs and sidetracking.

Adapts to run in both tensions and compression. Resists high temperatures. Activates jarring both ways with its double-acting hydraulic mechanical setup.
