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.
Package and Storage
25kg bags or according to customer's requirement.
Avoid high-intensity extreme pressure and prolonged exposure to strong sunlight. Keep container closed. Keep away from heat, sparks and flames.
