  • 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.
