Xanthan Gum

Definition - What does Xanthan Gum mean?

Xanthan Gum is a special type of chemical produced as a mud additive which can be used in oil drilling fluid. Xanthan gum mud additive is highly effective and environment friendly and has a great tolerance towards harsh drilling conditions such as sudden change in the temperatures, acidity and alkanity. This gum helps in increasing the penetrating ability of products and suspending performa to small solid materials as well as reducing the drilling pressure loss. One more advantage of this gum is that it reduces the damage to oil formation in the reservoir.

Petropedia explains Xanthan Gum

Xanthan Gum is environment friendly and its production source is bio fermentation using a sugar source. It is produced from the fermentation process with the help of the bacteria known as Xanthomonas campestris. This hums chemical composition is similar to the naturally occurring polysaccharide which is formed by Xanthomonas campestris bacteria on the cabbages. Some of the physical properties of this gum are as follows:

  • Particle Mesh – 80
  • PH value of 1% solution – 6 to 8
  • Drying Loss – less than 13%
  • Ashes – less than 13%
  • Pyruvic Acid – more than 1.5%
  • Shear ratio – more than 6
  • Rheological property – less than 0.5
  • Yield point – more than 30 pounds per 100 square feet
  • Salt tolerance @ 3rpm – more than 12.5
