A: Description of Oil Drilling Grade Xanthan Gum
Xanthan Gum is a high molecular weight polysacharide produced by viscous fementation, Its unique functionality compared to other commercial polysaccharides is provided by the actual structure of the xanthan gum molecule. It is widely used as a thinkener and stabilizer.

C: Applications:
Oil drilling and exploitation grade xanthan gum is specially used as mud additive for oil drilling and exploitations. Being an environmentally friendly and high efficiency mud additive, oil drilling and exploitation grade xanthan gum has an excellent tolerance to the changes of temperature, acid, alkaline and salt. Meanwhile, it can extremely increase the products penetrating ability and suspending performance to small solid materials, and reduce the pressure loss during drilling.
This xanthan gum can not only fasten the well bore, but decrease the damage to oil formation. It can also greatly raise the efficiency of drilling, workover and completion. As a biotype oil driver, oil drilling and exploitation grade xanthan gum can improve oil extraction rate and utilization factor of natural resources
