Hydrophobic additive SNPH-GFD
It is a product based on surfactants in an organic solvent.
Advantages
- Provides hydrophobic effect on any particles soaked in water, and their excellent wettability and compatibility with mineral and synthetic oils.
- Improves the temperature and rheological stability of the emulsion.
- Provides filtration control and resistance to contamination.
Purpose
It is used in cases of severe contamination of the invert emulsion with solid particles or when reservoir water enters the well and a potentially possible increase in viscosity due to solid particles soaked in water.
The recommended concentration is from 5-30 kg/m³.
