DYNAMUL-S serves as a secondary emulsifier in oil-base mud systems. When combined with primary emulsifier Dynamul-P, DYNAMUL-S can provide 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 180°C , the combination DYNAMUL-P/DYNAMUL-S can maintain high ES (electrical stability), low HTHP filtrate and desired rheological property.
DYNAMUL-S comprises of amidoamine, oxidized fatty acids and non-toxic organic solvent.
