PHPA mud | Energy Glossary

A class of water muds that use partially hydrolyzed polyacrylamide (PHPA) as a functional additive, either to control wellbore shales or to extend bentonite clay in a low-solids mud. As a shale -control mud, PHPA is believed to seal microfractures and coat shale surfaces with a film that retards dispersion and disintegration.

Field Applications of PHPA Muds | SPE Drilling & Completion - OnePetro

Summary Mud systems with partially hydrolyzed polyacrylamide polymer (PHPA) are used worldwide and have proved effective and versatile for inhibiting troublesome shale formations. We made significant changes in the generally recommended compositions for these systems and developed a systematic approach to applying them.

Recent advances of modified polyacrylamide in drilling technology

Consequently, polymer modification is required in drilling nowadays. The modified polyacrylamide reviewed in this paper is a polymer aqueous solution with high molecular weight, which has a similar density as water but a much higher viscosity. Further, it is a water-soluble, easily mixed dry granular, and non-gelling agent.
