Product Description
POLY PLUS contains copolymer and is used primarily as a borehole stabilizer to prevent reactive shale and clay from swelling and sloughing. POLY PLUS is also added to low-solids drilling fluids to increase lubricity, fluid viscosity, and to improve carrying capacity of air/foam injection fluids.
Advantages:
- Imparts high degree of lubricity
- Provides effective clay and shale stabilization
- Mixes easily with minimum shear in fresh water
- Flocculates non-reactive solids in reserve pit at low concentrations
- Breaks down chemically with household bleach (sodium hypochlorite)
- Prevents bit balling and balling on stabilizers and bottom hole assemblies by coating and lubricating solids.
Applications:
- Reduces fluid loss
- Improves wellbore stability
- Enhances slurry rheological properties
- Provides excellent cuttings encapsulation
- Can be well suited to low-solids, non-dispersed drilling mud systems
- Can be used in fresh water, seawater, sodium or potassium chloride brines.
Recommended Treatment:
Add POLY PLUS in concentrations of 0.5 to 5.0 liters per 1000 liters to drilling fluids. Mix slowly through a jet mixer or sift slowly into the vortex of a high-speed stirrer.
