Xanthan Gum is a high molecular weight exocellular polysaccharide derived from the bacterium Xanthomonas campestris using a natural, aerobic fermentation process. The process is conducted in a sterile environment where the pH, oxygen content and temperature are rigorously controlled. After fermentation is complete, the broth is sterilized and the gum is recovered by precipitation with isopropyl alcohol, then dried, milled and packaging under aseptic conditions.
- Minimized pumping friction in lime, freshwater and saltwater muds.
- Maximized drill bit penetration.
- Accelerated drilling rates in low viscosity/high shear conditions.
- Efficient suspension/solids transport in high viscosity/low shear conditions.
- Decreased solids buildup in drilling fluids.
- Handling high gravel concentrations.
- High viscosity at low concentrations.
- Stabilization of hole-cleaning fluids.
- Decreased damage to oil formation.
- Decresed maintenance expense.
- Lower total cost of operation.
