Rheological Additive for drilling muds and working fluids

BENTONE 34 rheological additive is the pioneering organoclay first used by the oil service industry to take advantage of the temperature resistant rheology characteristic of organoclays.


Viscosifying drilling fluids including:

            Oil-based drilling muds

            Invert emulsion muds

            Packer fluids

            Completion fluids

            Workover fluids

Based on:

            Mineral oils

            Low toxicity oils and fluids

            Synthetic Oils

            Diesel oil

            Crude oil

Key Properties

  • Confers superior downhole stability to muds and cost–effectively builds viscosity and yield point
  • Suspends weighting materials and other solids
  • Improves cuttings carrying capacity and hole cleaning
  • Increases emulsion stability
  • Aids control of fluid loss to the formation
  • Confers temperature stability to the fluid
  • Is not harmful to the environment

Use Levels

The level of use depends on the rheological properties needed, and the base oil being used. Pilot trials are recommended to optimize performance before field use.
