M-I Wate is a high-quality, non-reactive, drilling-grade barite (barium sulfate) used to increase the density of any mud system. This high-specific-gravity mineral is the most widely used weight material, has application in all drilling fluid systems and meets all API specifications for barite except density. M-I Wate is minimally abrasive and does not react with other drilling fluid additives or interfere with their function.

We recommend storage in a dry, well-ventilated area, in a closed container and away from incompatibles.
