AQUAGEL® treated sodium montmorillonite is a finely ground; premium-grade western natural sodium bentonite which meets the American Petroleum Institute Specification 13A; Section 9 requirements. AQUAGEL® viscosifier provides viscosity and gelling characteristics to most water-based drilling fluids. Applications / Functions: ? Viscosify anionic water-based drilling fluids ? Can reduce water seepage or filtration into permeable formations ? Can form a thin filter cake with low permeability ? Can promote hole stability in poorly consolidated formations. Advantages: ? Helps provide suspension for fluids weighted with barite or hematite ? Helps improve hole-cleaning capacity of drilling fluids ? Meets or exceeds API manufacturing standards (Section 9; Bentonite) ? Is environmentally responsible ? Can be added directly to fresh water or fresh water drilling fluids.
