ULTRAVIS
ULTRAVIS is a kind of treated xanthangum, a high-molecular-weight biopolymer used for increasing viscosity in water-base systems and produce thixotropic and highly shear-thinning for fluid.
The primary function of ULTRAVIS is to increases rheology, improves the carrying capacity and gel strength enhancing the suspension of weighting materials and other solids
- Highly performance viscosifier with small treatment
- Facilitate flow in the annulus with viscous characteristic for improved well bore stability with maximum hole-cleaning and suspension capacity.
- Improve hydraulics with Shear-thinning rheological profile
- Increase penetration rates with improving high-shear –rate viscosity and hydraulic horsepower at bit.
