M-I GEL viscosifier is a premium-grade bentonite (a sodium montmorillonite clay) that will yield 91 to 100 bbl of 15-cP mud per ton [1.7 m3/100 kg].
It is used as a primary filtercake-building, filtration-control and suspension agent in freshwater systems, and has application in all water-based drilling fluid systems. M-I GEL viscosifier is a high-quality product which meets the ISO 13500 Clause 9 (formerly known as API Spec 13A, Section 9) specifications for bentonite.

M-I GEL viscosifier is used to increase viscosity and reduce fluid-loss in water-based drilling fluids. It is a cost-effective means of achieving viscosity, fluid-loss control, and filtercake quality in freshwater and seawater muds. Typical concentrations for M-I GEL viscosifier range from 5 to 35 lbm/bbl [14.3 to 100 kg/m3].
As with all bentonite products, the yield decreases as water salinity increases. In muds containing more than 10,000 mg/L chlorides, the performance of M-I GEL viscosifier is significantly reduced unless prehydrated in freshwater before adding to the mud system.
Bioassay information is available upon request. Handle as an industrial chemical, wearing protective equipment and observing the precautions as described in the safety data sheet.
M-I GEL viscosifier is packaged in 100-lbm [45.4-kg] multiwall paper sacks, 40-kg sacks, big bags, and is available in bulk. Store in a dry, well-ventilated area. Keep container closed. Store away from incompatibles. Follow safe warehousing practices regarding palletizing, banding, shrink-wrapping, and stacking.
