NewPHPA™ shale inhibitor and rheology modifier is a liquid polymer emulsion additive designed primarily to provide shale stability, lubricity and viscosity in water-based drilling fluids. It is a high molecular weight, anionic polyacrylamide.
Shale Inhibition: coats drill cuttings and allows for their removal by the solids control equipment before becoming dispersed in the active drilling fluid system
Viscosity: aids in hole cleaning
Flocculation: enhances the removal of drill solids
Lubricity: enhances performance and reduces torque and drag
NewPHPA shale inhibitor and rheology modifier can be used in freshwater, seawater and sodium or potassium chloride brines, and is very effective in sweeps to aid in hole cleaning.
The NewPHPA polymer is used in concentrations of 0.2-2.0 lb/bbl (0.02-0.24 gal/bbl). A concentration of 0.1 gal/bbl is normally recommended. It can be added slowly through the hopper, to the pit or down the drill pipe during connections. The container should be thoroughly agitated before product use.

Handling and Storage
NewPHPA liquid polymer is extremely slippery. Use caution around spills. Avoid product degradation and equipment corrosion by not using iron, copper or aluminum containers or equipment. Use appropriate hygiene, clothing and personal protective equipment suitable for the work being done. Review the SDS thoroughly before using this product.
The NewPHPA shale inhibitor rheology modifier is available in 5-gallon (19-liter) pails and 55-gallon (208-liter) drums.
