(CAS # 7782-42-5)


DX-Graphite is a naturally occurring form of crystalline carbon. It is used in drilling fluids to provide lubrication, especially in complex drilling situations and also to contribute to the control of fluid loss and lost circulation while strengthening the wellbore. It can be used in combination with other lost circulation materials to control partial to severe losses.

  • Effective bridging and sealing agent for a wider range of formations
  • Reduces torque and drag in all mud systems by increasing lubricity
  • An inert material with no adverse effects on mud rheology
  • Non-damaging and reduces filter cake permeability
