PHPA is a high-molecular-weight PHPA copolymer used to encapsulate cuttings and performs as shale stability enhancer, viscosifier, flocculant, bit balling reducer and fluid loss control agent. PHPA rapidly adsorbs on water-wet solids to form a protective and lubricating film. This absorbed layer of polymer also contributes to filtration control. It is applicable with soft dispersive shales as well as areas with hard brittle shales. PHPA can be used in freshwater, seawater and monovalent brines systems. pH value of drilling fluids should be maintained in the range of 8.5-10.5 when use PHPA to achieve optimum results.
Stabilize water-sensitive formations and prevent bit balling
Used as effective sweep for periodic hole cleaning
Increases the yield of bentonite in low solids drilling system
Flocculant drill solids at low concentrations
Temperature stable up to 300°F
Excellent cuttings encapsulation to prevent cuttings dispersion
Improves the lubricity of most mud systems, particularly non-dispersed muds
Non-fermenting and no biocide required
Effective at low concentrations
A typical range is 0.25-2ppb
It must be added slowly through the hopper to avoid "fish eyes"generated
