Liquid Xanthan Gum FLOCON™ 4800

Xanthan Gum is well known to have excellent performance in high salinity brine. SNF obtained all the manufacturing and use patents of Pfizer FLOCON™ 4800 Xanthan Gum, which is recognized by experts around the world as the highest grade Xanthan available for EOR projects.


Xanthan Gum is a polysaccharide biopolymer. It is produced by the microbial action of xanthomonas campestris on a substrate of carbohydrate media, with a protein supplement and an inorganic source of nitrogen. The biopolymer is an extracellular slime which forms on the surface of the cells. The fermented both is pasteurized to kill microbes and precipitated from the broth by alcohol, then concentrated.

Limiting the degradation of a polymer solution

Polymers are sensitive to chemical, mechanical and thermal degradations. Chemical degradation is linked to the presence of contaminants such as Iron, Hydrogen Sulfide and Oxygen that can be detrimental to the polymer solution via oxido-reduction reactions susceptible to generate free radicals that will cut the polymer backbones.
Thermal degradation is related to the hydrolysis of the monomers. The acquisition of negative charges will lead to a coiling of the molecule if divalent ions are present. These types of degradation can be reduced by limiting the amount of reagents within the dissolution water or by adding protective additives to the product (F3P).


According to the reservoir characteristics, several products can be selected and fine-tuned to resist the reservoir conditions on a long-term basis.
Research & Development laboratories at SNF are working to extend these ranges with new products and constant improvements to the existing ones.
