Xanthan Gum


Xanthan Gum is an efficient viscosity increasing agent that also has a filtration loss reducing effect. It has excellent shear dilution performance and can effectively improve the flow pattern of drilling fluid. The use of Xanthan Gum drilling fluid has a low ultimate viscosity at high shear rates, which is beneficial for improving mechanical penetration rate. At low shear rates in the annular space, it also has high viscosity, which is conducive to the formation of a flat laminar flow and enhances the ability of drilling fluid to carry rock cuttings.

 Standards: API 13A-2010
