PHPA polyacrylamide
Detailed Product Description
Description
PHPA is a specially treated high molecular weight Partially Hydrolyzed Polyacrylamide polymer for all water-base drilling fluids. It functions as viscosifying agent, shale and bore-hole stabilizer, encapsulator, bentonite extender, flocculation agent and assist with fluid loss control.
Application & Features
PHPA is applicable in freshwater, seawater, saturated saltwater mud, KCl and solids free brine systems. It provides cuttings encapsulation, shale filming/inhibition, flocculation of drilled solids, viscosity and lubricity.
PHPA's strong encapsulating/filming action stabilizes clay and shale formations, blocks the absorption or inhibition of water from the drilling fluids, prevents clay and shale cuttings from disintegration and dispersion into the mud while carrying up the annulus from bit to surface.
Fluids contained PHPA has property of shear-thinning which helps maximize drill rate by exhibiting low bit viscosity and high lifting capacity at the lower shear rate at the annulus.
