Dispersible grade Xanthan gum Bio-xan D, equivalent to BARAZAN, DUOVIS or BORZAN D, suspension and hole cleaning in vertical and highly deviated wells as well as horizontal directional drilling applications.
Dispersible grade Xanthan gum BIO-XAN D 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. BIO-XAN D is a distinctive product and able to produce a thixotropic shear thinning fluid.
BIO-XAN D also acts as a very effective mud filtrate viscosifier.

Viscosify fresh water and brine-based fluids used for drilling, milling, underreaming, and gravel packing operations.
Suspend bridging agents and weighting materials in fresh water and brine systems.
Helps disperses easily in fresh water mud, and brines
Provides thixotropic properties and non-Newtonian flow characteristics over a wide salinity range at low concentrations
Provides excellent suspension without the need for clays
Minimizes the potential for formation damage
Add BIO-XAN D in concentration of 1.0 to 3.0 kg/m³ (0.4 to 1.1 lb/bbl) to drilling fluid. Mix slowly through a jet mixer or sift slowly into the vortex of a high-speed stirrer.
