Xanthan Gum

Detailed Product Description

Xanthan Gum is a high molecular weight polysaccharide biopolymer designed specially to viscosify water base drilling, completion and workover fluids. It's soluble in all water systems from freshwater, seawater, salt and heavy brine systems.

Application & Features
Xanthan Gum is a low-solids, cost-effective viscosifier widely used in drilling, completion and workover fluids. It builds viscosity and gel structure in all water base systems.

Drilling fluids contained Xanthan Gum remain nearly constant viscosity from below freezing to 270 static bottom hole temperature, in a pH range of 3 to 12 and, the product is non-toxic as well as biodegradable.

Solutions of Xanthan Gum exhibit pseudoplastic rheological properties. Its excellent and effective shear-thinning behavior help both increase penetration rates under high shear and provide excellent suspending action for optimum hole cleaning under low shear while viscosity is regained.
