Xanthan Gum
PZT-XG-1 xanthan gum is a natural polysaccharide biopolymer produced by fermenting Xanthomonas campestris bacteria on a carbohydrate feedstock. Long polymer chains entangle in water to form a pseudoplastic network that delivers strong low-shear-rate viscosity (LSRV) for hole cleaning and cuttings suspension at rest, while shear-thinning sharply under the high shear generated at the bit and pumps - keeping equivalent circulating density (ECD) low while drilling. Effective at treat rates of 0.25–1 lb/bbl, with good tolerance of salt and hardness relative to natural gums. Thermally stable to roughly 250–300°F (121–149°C).

Use Cases & Applications
- Primary viscosifier/suspension agent in water-based drilling mud (WBM)
- Cuttings transport in horizontal and extended-reach wells
- Completion and workover brines, including food-grade/low-toxicity applications
Pros
- Best-in-class shear-thinning profile per unit dosage of any common viscosifier
- Effective at very low treatment levels (0.25–1 lb/bbl)
- Good tolerance of salt and hardness compared to natural gums
Cons & Limitations
- Biodegrades under bacterial attack - needs a biocide co-treatment to protect shelf/tank life
- Higher cost per pound than guar gum or CMC
- Can lose molecular weight to enzymatic/oxidative breakdown over time at high temperature
