- Provides viscosity in water-based fluids
- Exhibits shear-thinning rheological properties
- Used in preparation of Ultra-PF™ systems
DESCRIPTION
Formavis Ultra is a high molecular
weight polymer which, when combined with a specially processed
starch derivative, Formatrol®, yields improved
static suspension and provides a highly shear-thinning viscosity
under dynamic conditions. The thermal stability of Formavis Ultra is 360°F with the addition of
Thermasal™-A, Thermasal-B, and
Formate Stabilizer. Formavis
Ultra is packaged in 50 lb or 25 kg sacks.
BASE FLUIDS
Formavis Ultra may be used in potassium
or cesium formate brines.
FEATURES
- Exhibits shear-thinning rheological properties
- Provides optimum viscosity for hole cleaning and
suspension
- Excellent salt, pH and thermal stability
MIXING INSTRUCTIONS
Formavis Ultra is readily mixed through
conventional mud mixing equipment.
