Introduction
———

Xanthan Gum is a high-performance biopolymer viscosifier for water-based drilling and completion fluids. It disperses in fresh water, seawater and brines, and delivers strong suspension and shear-thinning rheology for improved hydraulics and hole cleaning. It is designed to be effective up to 121°C (250°F).
To meet different field conditions and performance targets, DongYU Xanthan Gum is supplied in multiple viscosity grades, allowing optimized rheology in different salinity, solids and temperature environments.

 Typical example

• API 13A
• ISO 13500:2008

Applications / Functions
—————

• Viscosifies freshwater and brine-based fluids used for drilling, milling, underreaming and gravel-packing operations

• Suspends bridging agents and weighting materials in freshwater and brine systems

•  Provides shear-thinning behavior for stable hydraulics and efficient pump performance

•  Helps improve cuttings transport and wellbore cleanliness

Advantages
———

• Highly effective viscosifier at low treatment levels
