Partially Hydrolyzed Polyacrylamide PHPA

Product description: 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.

Same product: Hiliberton: EZ Mud DP  Schlumberger: Poly-Plus RD

Application/Function: 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 viscosify clear-water and low-solids drilling fluids.
