Detailed Product Description

Xanthan gum is a high molecular weight polysaccharide produced by viscous fermentation. 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 thickener and stabilizer.

Oil drilling and exploitation grade xanthan gum is specially produced 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. The more important point is that it can furthest protect natural environment.
