Component: It is a multifunction anti-sloughing fluid loss agent. Made from high class mixed hydrocarbon, plant extract with organic hydrophile through grafting reaction.
Feature: Black brown powder, soluble in water.
Usage: Under a proper increase of viscosity, it can reduce the water loss obviously, control well wall expansion & hole shrinkage, reduce torque, prevent adhesion and drill jamming, at the same time, it has a certain anti-dirty ability.
