• Can be ran with standard completion fluids and / or nitrogen
  • Setup to open and close at predetermined pressures
  • Generous flow ports to prevent motor stalls in high flow rate situations
  • Internally dampened to allow for use with Extended Reach Tools such as the WOS EaZyDrill or specialty milling tools such as the WOS HammRDrill.
  • The compact design minimizes additional length and rigidity added to the BHA as compared to similar tools


  • Does not starve motor which can lead to premature motor failure
  • Avoids the need to drop a ball during operations keeping flow paths open
  • Carbide jets allow for max rate without the risk of washing out for better hole cleaning
  • Allows for additional annular velocities with rate limited tools below the GovernR
  • Easily configurable to client specified needs for optimal hole cleaning

About This Product

The WOS GovernR is a smart AV sub that increases velocities while allowing for generous flow below the smart sub making it the perfect downhole device for assisting in hole cleaning. Whether limited by a downhole motor or an extended reach tool the ability to bypass some of the fluid above these tools through a sub that allows for increased pump rates and thus an increase in annular velocities is a crucial aspect of removing debris from the wellbore. The smart sub not only opens and closes via differential pressure but can be adjusted to the needs of the operator.
