PHPA

Term · Oil and gas · MLC-T-OAG-002779

An abbreviation for partially hydrolyzed polyacrylamide, a synthetic polymer commonly used as a shale inhibitor and viscosifier in water-based drilling fluids. PHPA works by encapsulating shale cuttings, preventing their hydration and dispersion, and by increasing the fluid's viscosity. It is effective in maintaining wellbore stability in reactive shale formations.
