Bentonite By Vision Minerals & Energy

BentoniteVision Gelt: Vision GEL viscosifier is a premium-grade wyoming bentonite (a sodium montmorillonite clay) that will yield 91 to 100 barrels of 15-cP mud per ton (1.7 m3/100 kg). It is used as a primary filter-cake-building, filtration-control and suspension agent in freshwater systems, and has application in all water-base mud systems. Vision GEL is a high-quality product which meets the API specifications for bentoniteTypical Physical PropertiesPhysical appearance- Light tan/gray-green powderSpecific gravity- 2.3-2.6Bulk density- 48-52 Ib/ft 3 (769-833 kg/m3)API SpecificationsSuspension propertiesViscometer dial reading at 600 rpm- 30, minYield point/ plastic viscosity ratio- 3, maxFiltrate volume (2X30-7.5 min. vol) - 15 cm3, maxResidue >75 micron (wet screen)- 4% wt, maxMoisture- 10% wt, maxSuspension of 22.5 grams in to 350 cm3 water.ApplicationsVision GEL 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. Typical concentrations for Vision GEL range from 5 to 35 Ib/bbl (14.3 to 100 kg/m3). As with all bentonite products, the yield decreases as water salinity increases. In muds containing more than 10000 mg/l chlorides, the performance of Vision GEL is significantly reduced unless prehydrated in freshwater before adding to the mud systemAdvantagesHydrates more than other types of clays and is best for generating viscosity, developing gels for suspension and controlling filtrationSmall particle size, unique flat shape and high surface area of hydrated vision GEL provides superior filtration characteristicsPromotes the deposition of thin, compressible filter cakes in the wellboreLimitationsPerformance reduced in salty (> 5000 mg/I/CI-) or hard (>240 mg/ I Ca++) waters due to decreased hydrationToxicity and HandlingBioassay information is available upon request. Handle as an industrial chemical, wearing protective equipment and observing the precautions as described on the Transportation and Material Safety Data Sheet (MSDS)Packaging and StorageVision GEL is packaged in 100-Ib (45.4-kg), multi-wall, paper sacks; 40-kg sacks; big bags; and is vision GEL should be kept as dry as possible
