TROL-STAR HV
TROL-STAR HV is a combination of high-quality, water-soluble bio polymers designed to control fluid loss and increase viscosity in water base muds. TROL-STAR HV provides immediate viscosity and fluid loss control in both fresh and saline water.
Application
TROL-STAR HV controls fluid loss and provides viscosity in freshwater, seawater, KCl and salt muds. Forming a thin, resilient, low-permeability filter cake TROL-STAR HV minimizes the potential for differential sticking and the invasion of filtrate/mud solids into permeable formations.
Advantages
- Effective in low concentrations for controlling fluid loss and building viscosity
- Encapsulates shale particles to inhibit swelling and dispersion
- Functions over a wide range of salinity, hardness and pH levels
- Applicable in all water-base fluids, ranging from low-solids, non-dispersed polymer systems to high-density, dispersed systems
Typical Usages
| Typical Amounts of TROL-STAR HV Added to freshwater | ||
|---|---|---|
| Drilling Application | lb/100 gal | lb/bbl |
| Normal fluid loss | 1.2 - 2.5 | 0.5 - 1 |
| Add TROL-STAR HV slowly at the hopper or mixing system to prevent clumping or "fish eyes" | ||
| TROL-STAR HV is biodegradable and may require the use of biocides if the drilling fluid will be circulated for long periods. | ||
Typical Properties
| Physical Appearance | White to beige free-flowing powder |
|---|---|
| Specific Gravity | 1.5 - 1.6 |
| pH (1% solution) | 6.5 - 8.0 |
Packaging
TROL-STAR HV is packaged in 50-lb (22.7-kg) multi-wall bags and in 5 gallon (18.9L) buckets
