PRODUCT DE
Oil Drilling Grade Xanthan Gum--Class 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. It is a distinctive product and able to produce a thixotropic shear thinning fluid. It also acts as a very effective mud filtrate viscosifier.
APPLICATION
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.
ADVANTAGES
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
Stable at temperatures up to 250°F / 121°C
Minimizes the potential for formation damage
USAGE
Add it 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.
STORAGE
Avoid high-intensity extreme pressure and prolonged exposure to strong sunlight.
Keep container closed.
Keep away from heat, sparks and flames.
