PHPA (Partially Hydrolyzed Polyacrylamide)

PHPA (PARTIALLY HYDROLYSED POLY ACRYLAMIDE) is a white granular/powder  copolymer of anionic character and high molecular weight.

It is water-soluble and primarily used for

• Reducing fluid loss
• Increasing viscosity of drilling mud and protecting shale
• Cutting in fresh water, calcium, sodium brines and mud systems.

It maintains borehole stability by preventing shale swelling and erosion.

Attributes & Benefits:

• PHPA coats cuttings and functions as an inhibitor
• It restricts the interaction of water and shales
• It can be used as a flocculent in clear water drilling
• Resistant to bacterial fermentation
