Xanthan Gum (Drilling Grade)
Product Description
1. Product Overview
Xanthan Gum (Drilling Grade) is a high-molecular polysaccharide biopolymer produced by microbial fermentation, specially designed for water-based drilling fluids. It acts as an efficient viscosifier, fluid-loss controller and suspending agent.
It maintains stable rheological properties under high temperature, high salinity and high calcium conditions, effectively stabilizes the wellbore and carries cuttings. It is widely used in deep wells, directional wells, horizontal wells and brine drilling fluid systems.
2. Key Features & Functions
- Excellent shear-thinning property: high static viscosity for superior cuttings suspension; low viscosity under pumping for better fluidity and higher drilling efficiency.
- Outstanding thermal and salt resistance: stable performance in high temperature and high-salinity / saturated brine systems.
- Effective fluid loss control: forms compact, low-permeability filter cake to reduce filtrate invasion and protect formation.
- Strong cuttings carrying capacity: effectively suspends barite and weighting materials, cleans wellbore and prevents settling.
- Good compatibility: compatible with various drilling fluid additives, suitable for fresh water, seawater and brine systems.
- Eco-friendly: biodegradable and low-toxic.
