OBM-Viscosifier is a high-quality grade of organophilic clays which is widely used in oil-based mud systems as a viscosifier. OBM-Viscosifier optimize hole cleaning and suspend cuttings and weighting agents. It has a long-term effect, and is stable in low to high temperatures (up to 350 °F). It is not suitable for clay-free oil-based muds.


  • Provides excellent rheological and gelling properties
  • Easy to mix
  • Compatible with most types of regular oil-based muds
  • Stable up to 350 °F
  • Helps in lowering filtration
  • Excellent for hole-cleaning due to improving hydraulics
