Hyperdrill AF 247RD has been developed to provide improved shale stabilization/inhibition in drilling fluids with minimal effect on rheology. It is suitable for use in fresh water, seawater, K+ polymer, and other inhibitive water-based systems.
It’s improved rheological properties allow for the addition of higher concentrations with reduced viscosity humping in solids laden muds. Dosage rates are 2.0-6.0 kg/m³.
