Reversible invert-emulsion filtercake breaker system
Destroy oil- and synthetic-based reservoir drill-in fluid (RDF) filtercake and dissolve bridging solids.
VG-PLUS organophilic clay is an improved viscosifier and gelling additive for all synthetic-based and VERSACLEAN mineral oil-based systems.
VG-PLUS clay is an amine-treated bentonite that improves the carrying capacity, gel strength, and suspension of weight material. It also assists in improving filtercake quality, and filtration control.
VG-PLUS clay has particular application in mixing plants. The product provides viscosity for building new fluids that have not been exposed to shear or temperature.

VG-PLUS clay is an effective viscosifier in mineral-oil- and synthetic-based drilling, coring, workover and completion fluids. It can also be used in specialty fluids such as casing packs, packer fluids, lost circulation pills, and spotting fluids where viscosity is required.
The VG-PLUS clay is used to increase gel strength and viscosity in mineral oil and synthetic-based muds. It is especially useful in blending plants where high shear and temperature are not available to obtain full dispersion and hydration. Although it provides more viscosity in these situations than other organophilic clays, even the VG-PLUS clay will not fully yield. For this reason, caution should be used to avoid overtreatment until the fluid can be circulated through the wellbore.
Typical concentrations range from 2 to 10 lbm/bbl [5.7 to 28.5 kg/m3] for most drilling applications, depending on the base fluid and water content. For maintenance, occasional treatments should be added as needed to maintain the flow properties and gel strengths in the desired ranges. Specialty applications such as casing packs and packer fluids generally require concentrations in the range of 10 to 15 lbm/bbl [28.5 to 43 kg/m3].
Bioassay information is available upon request. Handle as an industrial chemical, wearing protective equipment and observing the precautions described in the safety data sheet.
VG-PLUS viscosifier is packaged in 50-lbm [22.7-kg] multiwall paper sacks. 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.
