• Black Diamond’s Hydraulic Jar Accelerator is a hydraulic spring that stores energy when tension is applied to the drilling string.
    • During the jarring stroke, the energy is released upwards to accelerate the drill collars and the upper portion of the jar, intensifying the jarring impact.
    • Recommended for use in extended reach or highly deviated wells where jar performance could suffer due to hole drag.
    • Can be utilized in shallow holes where little pipe stretch is available.
    • The sealed and lubricated spline drive provides long service life under high torque and stroking applications.
    • Standard seals rated to 250°F (120°C); High temp seals rated to 400°F (200°C) for hot hole environments.
    • External sealing surfaces are tungsten carbide-coated to enhance wear and corrosion resistance.
