Key Advantages

  • Sealing micro-particles to reduce non-productive time and improve wellbore stability
  • Plugging pores to reduce permeability of filtercake
  • Readily dispersible in water and oils
  • Upon redispersion, high tolerance in salts, multivalent ions and acid
  • Flatter Yield Point response of formulated fluid at raising temperatures vs. organoclays
  • Sealing additive for oil- and wate-rbased muds for temperatures up to 177 °C (350 °F)
