Partially Hydrolyzed Polyacrylamide PHPA
Shale Inhibitor / Viscosifier / Flocculant
PHPA (powder form) is a readily dispersible additive designed to provide cuttings encapsulation and shale stabilization in freshwater to saltwater drilling fluids ranging from low solids to weighted muds.
PHPA is formulated for easy mixing with improved dispersion to eliminate "fish eyes", which occurs when mixing either large quantities rapidly or mixing high polymer concentrations where good mixing equipment is unavailable. PHPA acts as a viscosifier, friction reducer, and flocculants, while also providing some fluid-loss control. PHPA also delivers cuttings encapsulation and improves wellbore stability, making it ideal for slim hole and continuous-coring applications.
Readily dispersible and does not form "fish eyes"
Excellent cuttings encapsulation limits cuttings dispersion
Improves shale stabilization
Powdered material has significantly lower toxicity than invert-emulsion, liquid polymers
Highly concentrated product (> 90% activity) reduces transportation costs and storage space requirements
Helps prevent balling on the bit, stabilizers and bottom hole assembly by coating and lubricating solids
Enhances removal of drill solids
Can be used to viscosity clear-water and low-solids drilling fluids
Enhance the carrying capacity and half-life of foam drilling fluid
Does not require biocides
Stable in monovalent salt (NaCl, KCl, etc. ) environments
Effective in small concentrations
Can be destroyed with oxidizing agents when desired
Appearance: White powder
PH: 6.0 - 8.0
Molecular weight: 8 million-20 million
Add PHPA in concentration of 0.7 to 4.3 kg/m³ (0.2 to1.5 lb/bbl) to any active system. Mix slowly through a jet mixer or sift slowly into the vortex of a high-speed stirrer.
Package and Storage
