Partially Hydrolyzed Polyacrylamide Liquid - Purity(%): 100

PETRA
PHPA L is a copolymer of acrylamide and sodium acrylate.
It is a
high-performance anionic liquid polymer designed for shale stabilization, fluid
loss control, and viscosity enhancement in water-based drilling fluids.
It
effectively encapsulates shale cuttings, reduces dispersion, and improves
wellbore stability.
Excellent Shale Inhibition: Encapsulates reactive shale and clay cuttings to prevent swelling, sloughing, and dispersion into the drilling mud.
Viscosity Building: Efficiently boosts the viscosity of fresh water, sea water, and brine fluids for superior hole cleaning.
Friction & Drag Reduction: Significantly reduces mechanical drag and fluid friction losses in the drill string, optimizing hydraulic efficiency.
Convenient Liquid Form: Disperses rapidly in water without forming stubborn "fish-eyes" or lumps, saving critical mixing time.
Cuttings Encapsulation: Coats drilled solids so they stay intact, allowing for easier removal at the surface shale shakers.
Filter Cake Enhancement: Aids in forming a thin, low-permeability filter cake along the wellbore wall to reduce fluid loss.
Thermal Stability: Maintains reliable molecular structure and performance in moderate to high-temperature downhole environments.
Balling Prevention: Keeps sticky clay formations from adhering to the drill bit and bottom-hole assembly (BHA).
Low Toxicity Profile: Environmentally safe and biodegradable under standard conditions, minimizing disposal compliance issues.
Calcium Tolerance: Formulated to resist hardness and maintain stability even in mud systems contaminated with cement or gypsum.
