Product Sheet VG-SUPREME Organophilic Clay Viscosifier
A high-performance rheological additive for invert emulsion and all-oil drilling fluids.
VG-SUPREME viscosifier is a high-performance rheological additive for invert-emulsion and all-oil drilling fluids.
It provides excellent antisag features and exhibits a very rapid yield under low-shear and low-temperature conditions. VG-SUPREME viscosifier is ideal for minimizing barite sag in extended-reach wells and for preventing settling in low-shear mud plant operations.

|Physical appearance||Very-light cream powder|
VG-SUPREME viscosifier is a specially formulated organophilic clay, capable of developing outstanding low-shear-rate viscosity and suspension properties. It can be used as the primary or supplemental viscosifier, depending on the specific drilling conditions. VG-SUPREME viscosifier can be used in virtually any base oil or synthetic fluid, as well as all-oil drilling fluids.
VG-SUPREME viscosifier is an effective replacement for gelling agents in both mud plant and onsite well applications, where rapid yield is essential to prevent static or dynamic settling. Unlike some other organophilic clays, VG-SUPREME viscosifier will develop the maximum rheological properties shortly after being mixed with minimal shear. This eliminates situations where rheology would increase for several circulations after the organoclay addition. Laboratory tests show that VG-SUPREME viscosifier generates the same or equal rheology more rapidly than standard organophilic clays.
When used for preventing barite sag and improving hole cleaning, VG-SUPREME viscosifier treatments should range between 0.1–1.0 lbm/bbl. A concentration of 1.0- to 3.0-lbm/bbl VG-SUPREME viscosifier can be used at the mixing plant for initial mixing, or as a supplement to 1.0- to 5.0-lbm/bbl standard organoclays.
VG-SUPREME viscosifier is an ideal additive for dilution premixes used to reduce the mud weight or to decrease the low-gravity solids concentration. For normal maintenance, concentrations of 1.0–3.0 lbm/bbl can be used when maintaining rheology or 3.0–10.0 lbm/bbl when increasing the rheology by premix additions.
