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 freshwater, 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.
Hyperdrill AF 247RD is also an effective anionic polymer flocculant used for clear water drilling. It should be added through a chemical barrel at the flow line or injected directly into a centrifuge from a premixed polymer tank, usually in a 0.5% stock solution.
It can also be used for fluid clarification when added at the centrifuge in sumpless drilling operations.
