Filtrate reducer for oil-based drilling fluids. CS-EFLO HT

Product Features and Applications

CS-EFLO HT is a filtrate reducer for drilling fluid. It is a chemical modified natural polymer derivative of chemical modified. This product has good water solubility. Can be used in combination with XC to adjust rheological properties of drilling fluid system, and can improve the dynamic/plastic ratio and low shear rate viscosity of drilling fluid system. Has good shear dilution property to improve the suspension and carrying capacity of drilling fluid. Low flowback pressure and excellent reservoir protection performance. Suitable for all kinds of water-based drilling fluid system, easy to use. The product is environmentally friendly and non-toxic.
