Economical rheological additive for invert drilling muds

BENTONE 905 rheological additive is a cost-effective organobentonite viscosifier and suspending agent for oil–based drilling fluids, invert emulsion drilling fluids. BENTONE 905 is suitable for drilling fluids with a continuous phase of diesel, crude oil or mineral oil. It imparts to the formulation the temperature stable rheology characteristic of organoclays.

Key Properties

• Cost-effectively builds viscosity and yield point in diesel and mineral invert muds • 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
