- Clarizan™ biopolymer

Clarizan™ biopolymer

Clarizan™ biopolymer is a clarified, high-viscosity xanthan gum that can be used in most types of water-based fluids where clarity of the solution is critical. A high-performance powder, Clarizan™ biopolymer provides excellent carrying and suspending characteristics. It is compatible with most mud additives commonly used in water-based fluids for rheology control.

Clarizan™ biopolymer has excellent shear thinning properties that promote thinning of the fluid at high velocities and thickening of the fluid at low velocity. It performs effectively over a wide range of pHs in fresh water, salt water and various brine-based workover and completion fluids.

Advantages

Excellent shear thinning properties produce viscous fluid when needed, thin when required
Excellent suspension properties
Stable rheology control
Requires lower concentrations than other viscosifiers
Promotes higher penetration rates
Minimizes formation damage
Reduces circulating pressure losses
Effective friction reducer
Resists shear degradation
Reduces barite sag

Cost

Superior inherent viscosity development makes Clarizan™ biopolymer highly cost-effective compared to competitive materials.
