Antenna Sub - Electrical Gap Sub

Overview, Features & Benefits

The Antenna Sub is placed in the bottom hole assembly to create an electrical break in the drill string. This electrical break is used by Electromagnetic Measurement While Drilling (EM MWD) equipment to initiate a subsurface signal which conveys real-time drilling parameters and information to the surface.

Our latest generation of Antenna Sub has been designed for quick and easy service in any shop capable of servicing downhole tools.

  • Rugged design, will not wash out and lead to failures.
  • Versatile design allows for easy servicing of sealing features and quick turn-around.
  • Shop serviceable in any location capable of making and breaking drill pipe connections.
  • When coupled with the Arrival Antenna Rod, any existing EM system can be adapted for use with the Gap Sub.
