NightHAWK Accelerator

Get Out of a Tight Spot

Rubicon’s NightHAWK Accelerator can be strategically placed anywhere in the drill-string based on the application to increase jarring forces in both tension and compression forces. The increase in jarring forces is recommended in highly deviated wells, extended reach wells and any other wellbore where issues related to hole drag are imminent. Its unique loading system stores energy during jarring procedures and releases to accelerate drillstring components, maximizing the overall jarring impact. Our jars are completely sealed to prevent cuttings or drilling fluids from damaging the tool.

Making it better

The NightHAWK Accelerator’s jarring action prevents loss of high cost BHAs.

Runs in both tension and compression applications. Operates in even the most extreme temperatures. Triggers jarring in both ways with its double action set up. Proves effective throughout the drill string. Yields uncomplicated jarring procedures with operations based on drilling jar specs.
