OBM Secondary Emulsifier is a high-quality grade of secondary emulsification agents for oil-based drilling fluids. OBM Secondary Emulsifier is widely used in in different mud densities and oil/water ratios in order to increase thermal stability, improve resistance to contaminants and wetting solids in OBM systems.


  • Improve thermal and emulsion stability
  • Wetting the drill solids with oil phase
  • Increase emulsion stability characteristic
  • Reduce filtration volume
  • Compatible with most types of regular oil-based muds
  • Easy to mix
  • Improve rheological stability
  • Stable up to 300°F
  • Increase resistance of the mud to the contaminants
