Secondary Emulsifier provides excellent and very Stable Emulsion and oil wetting agent. It contributes to temperature stability and HTHP filtration control and is most effective over a wide range of temperatures and also in the presence of contaminants .It provides viscosity and filtration control and temperature stability.
Emulsifier include primary emulsifier and secondary Emulsifier . Emulsifier use for oil based drilling mud. primary emulsifier in oil-base mud systems. It is formulated to give good .emulsification, improved thermal stability of the invert emulsion, and enhanced high-temperature,high-pressure (HTHP) filtration control. Through comprehensive tests in a number of oil-base mud.formulations with various base oils, mud densities, oil/water ratios and hot-rolling temperatures, it proves that at working temperature up to 149oC (300oF), CPMUL-P can maintain high ES(electrical stability), low HTHP filtrate and desired rheological property.
