Viscosifier
API Xanthan gum
API Grade Xanthan Gum is specially produced as mud additive for oil drilling and exploitations. Being an environment 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.

Description
Product Description
Xanthan gum is a water-soluble polysaccharide, commercially produced by a distinct fermentation process of Xanthomonas campestris, and does not contain any other polysaccharide, such as starch, guar gum or other naturally occurring polymers or their derivatives. Xanthan gum is an off-white, free flowing granular powder.
Oceanvis Xanthan gum is a premium quality biopolymer powder designed to provide maximum solids suspension and hole cleaning in vertical and highly deviated wells as well as horizontal directional drilling applications. Oceanvis Xanthan gum is a distinctive product and able to produce a thixotropic shear thinning fluid. Oceanvis also acts as a very effective mud filtrate viscosifier.
