M-I Gel viscosifier is used to increase viscosity and reduce fluid-loss in water-base drilling fluids. It is a cost-effective means of achieving viscosity, fluid-loss control and filter-cake quality in freshwater and seawater muds. Used as a primary filter-cake-building, filtration-control and suspension agent in freshwater systems, M-I Gel viscosifier is a premium-grade bentonite that has applications in all water-base mud systems.
M-I Gel hydrates more than other types of clays and is best for generating viscosity, developing gels for suspension and controlling filtration. Its small particle size, unique flat shape and high surface area of hydrated M-I Gel viscosifier provides superior filtration characteristics. However, the performance of M-I Gel viscosifier is significantly reduced in salty waters unless prehydrated in freshwater before adding to the mud system. M-I Gel should be handled as an industrial chemical, while wearing protective equipment and observing the appropriate safety measures. We recommend storage in a dry, well-ventilated area, in a closed container and away from incompatibles.
