3)Oil Drilling Grade

It is specially produced as mud additive for oil drilling and exploitation. Being an ecvironment friendly and high efficiency mud additive, Oil Drilling & 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 & 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.
