Pressure balanced to eliminate effects of hydrostatic pressure & pump open forces
UltrAccelerator
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.

NXG Multi-Activation Circulation Sub
Multi-Activation NXG Circulation Sub has been designed not only to overcome the most complex circulation challenges – but to do so with optimum efficiency and total reliability as part of your BHA.
Multi-Activation Circulation Sub bypasses the need to break the drill string as part of the process: no ‘ball’ or ‘dart’ drop devices are required.
An innovative internal mechanism allows flow ports in the outer body to be opened and closed from the surface by 2 methods, simply via the operation of the mud pump.
Upon activation, a shut-off mechanism closes the tool inner bore, allowing lost circulation material to be pumped out through the side ports, even when the hole is packed off.
The Circulation Sub can be activated (opened or closed) as many times as you require during an individual drilling operation.
