The DOG drilling on gauge sub has been specifically designed to deliver at-the-bit reaming. Its short body design and durable cutting structure enables placement between the bit and motor for directional applications. This results in a smoother build section and reduction in hole drag allowing for better weight transfer to the drill bit.


  • Directional projects where maintaining hole gauge is problematic
  • Directional wells where doglegs demand reaming runs through build sections
  • Near-bit reaming in packed-hole assemblies, sub is first point of stabilization for BHA
