Application & Advantages

Application
SPNH can be applied in various freshwater and saltwater drilling fluids. Its recommend dosage is 7 - 14ppb.

Advantages
It can resist high temperature, resist salt, reduce filtration loss, and shows good lubricant and inhibit performance.
It can form thin and resilient mud cake on the borehole, perform good lubricating effect and good rheological property.
It can resist high temperature up to 200℃, so that it can be applied in deep wells with high temperature.
