Application/Function
SMP controls fluid loss in most of water based drilling fluids. SMP-1 is used in fresh and gentle brackish water based muds. SMP-2 is used in high brackish water based muds.


Advantages

  • High temperature resistance (up to 180 ℃), so it can be applied in deep and ultra-deep wells.

  • Reasonable salt resistance, so it can be applied in freshwater, saltwater, saturated saltwater and seawater drilling and completion fluids.

  • Low viscosity effect, so it can be applied to high-density drilling and completion fluids.

  • Compatible with other additives.
