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.

Treatment Recommendation

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.
