Anionic Polymer PHPA For Oil Drilling Fluid Viscosity Enhancement

Partially Hydrolyzed Polyacrylamide (PHPA) is a specific form of polyacrylamide widely used in the oil and gas industry, especially in drilling and shale stabilization applications. PHPA functions as a high-performance shale inhibitor, viscosifier, and encapsulating agent in water-based drilling fluids.

Shale Stabilization: PHPA inhibits the hydration and dispersion of shale and clay formations, effectively preventing wellbore collapse and reducing drilling problems.

Cuttings Encapsulation: It coats and encapsulates drill cuttings, preventing dispersion and aiding in their removal from the wellbore.

Lubrication and Drag Reduction: Improves the lubricity of drilling fluids, reducing torque and drag during horizontal and directional drilling.

Fluid Loss Control: Enhances the filtration control of drilling fluids, reducing fluid invasion into the formation.

Environmentally Friendly: As a water-soluble polymer, PHPA is less toxic and more environmentally friendly compared to oil-based drilling additives.

PHPA-type polyacrylamide is especially suitable for use in freshwater, saltwater, and potassium-based mud systems, making it ideal for complex drilling environments.
