Usages:
Xanthan Gum is specially produced as mud additive for oil drilling and expoitation. Being an ecvironment friendly and high efficiency mud additive, Xanthan Gum Oil Drillng Grade 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 also decrease the damage to oil formation. Xanthan Gum can also greatly raise the efficiency of drilling, workover and completion. As a biotype oil driver, Xanthan Gum Oil Drilling Grade can improve oil extraction rate and utilization factor of natural resources. The more important point is that it can furthest protect natural environment.
