BENTONE 903 rheological additive is our most cost-effective organobentonite viscosifier and suspending agent for oil–based invert emulsion drilling fluids, BENTONE 903 is suitable for drilling fluids with a continuous phase of diesel or crude oil. It imparts to the formulation the temperature stable rheology characteristic of organoclays. Ideal for well site application. Applications Viscosifying Invert emulsion drilling fluids based on: Diesel oil Crude oil Attributes BENTONE 903 gellant • 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
