How it improves wells

VG-SUPREME organophilic clay viscosifier is a high-performance rheological additive for invert-emulsion systems. It provides excellent antisag features and exhibits a rapid yield under low-shear and low-temperature conditions. It is ideal for minimizing barite sag in extended-reach wells and for preventing settling in low-shear mud plant operations. It is an effective replacement for gelling agents in mud plant and onsite well applications where rapid yield is essential for preventing static or dynamic settling. Unlike other organophilic clays, VG-SUPREME viscosifier will develop the maximum rheological properties shortly after being mixed with minimal shear, eliminating situations where rheology would increase for several circulations after the organoclay addition. Laboratory tests show that it generates the same or equal rheology more rapidly than standard organophilic clays.


  • Develops low-shear-rate viscosity efficiently
  • Enhances hole-cleaning capacity
  • Yields rapidly
  • Proves effective in low-shear and low-temperature mixing conditions


Excessive treatment with VG-SUPREME viscosifier tends to increase mud rheology at cold temperatures. In deepwater applications, the rheology should be measured at two or three temperatures, including the flow line temperature.
