Product Description
PHPA Emulsion contains partially hydrolyzed polyacrylamide / polyacrylate (PHPA) copolymer and is used primarily as a borehole stabilizer to prevent reactive shale and clay from swelling and sloughing. It is also added to low-solids drilling fluids to increase lubricity, fluid viscosity, and to improve carrying capacity of air/foam injection fluids.
Application/Function
Can be used in fresh water, seawater, sodium or potassium chloride brines
Provides excellent cuttings encapsulation
Improves wellbore stability
Enhances slurry rheological properties
Can be well suited to low-solids, non-dispersed drilling mud systems
Reduces fluid loss
Advantages
Mixes easily with minimum shear in fresh water
Provides effective clay and shale stabilization
Imparts high degree of lubricity
Non-fermenting
Breaks down chemically with household bleach (sodium hypochlorite)
Flocculates non-reactive solids in reserve pit at low concentrations
Liquid product for easy mixing and rapid yield
Prevents bit balling and balling on stabilizers and bottom hole assemblies by coating and lubricating solids
Technical Data
Appearance: Thick, opaque cream liquid
PH: 6.5 - 7.5
Active matter : 35.0%-50.0%
Recommended Treatment
Add PHPA in concentrations of 4.0 to 8.0 liters per 1000 liters to drilling fluids. Mix slowly through a jet mixer or sift slowly into the vortex of a high-speed stirrer.
Package and Storage
200kg drums or according to customer’s requirement. Avoid high-intensity extreme pressure and prolonged exposure to strong sunlight. Keep container closed. Keep away from heat, sparks and flames.
