Secondary Emulsifier for Oil Base Mud CPMUL-S 

Secondary Emulsifier CPMUL-S serves as a secondary emulsifier in oil-base mud systems. When combined with primary emulsifier CPmul-P, CPMUL-S can provide good emulsification in invert oil mud

, improved thermal stability of the invert oil mud 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), the combination CPMUL-P/CPMUL-S can maintain high ES (electrical stability), low HTHP filtrate and desired rheological property.

Secondary Emulsifier CPMUL-S comprises of modified amidoamine, oxidized fatty acids and low-toxic organic solvent.
