Partially Hydrolyzed Polyacrylamide PHPA
Product Description
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 improved wellbore stability, making it ideal for slim hole and continuous-coring applications.
Function
Readily dispersible and does not form "fish eyes"
Excellent cuttings encapsulation limits cuttings dispersion
Provides improved 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
Aids in preventing balling on the bit, stabilizers and bottom hole assembly by coating and lubricating solids
Enhances removal of drill solids
Can be used to viscosify clear-water and low-solids drilling fluids
Advantages
Is non-fermenting
Does not require biocides
Stable in monovalent salt (NaCl, KCl, etc. ) environments
Effective in small concentrations
Can be destroyed with oxidizing agents when desired
