RXSOL PHPA LIQUID is easy to mix and yields rapidly. PHPA active concentration of the active system should be maintained in the range of 0.5 - 1.5 lb/bbl by constant additions.
The normal application is 1.75 to 3.5 lb/bbl used in combination with KCl Potassium Chloride at 3 - 8% provides effective inhibition.
PHPA is a co-polymer of anionic character and high molecular weight. very strong ionic group and ionizes completely in aqueous solutions. In applications where the precipitation of mineral salts is undesirable, the incorporation of a polymer containing even a small quantity of AMPS can significantly inhibit the precipitation of divalent cations. It is a water-soluble polymer, which is primarily used as a highly efficient fluid loss reducer, Viscosifier and protective colloid for shale’s and cutting in fresh water, calcium, sodium brines and KCL mud systems. It is compatible with most of the drilling fluid products, biopolymers, PAC, CMC. It maintains borehole stability by preventing shale swelling and erosion.
PHPA LIQUID provides provides excellent cuttings encapsulation and improved wellbore stability. PHPA LIQUID is PHPA Polymer, a high-molecular-weight synthetic polymer designed as a shale inhibitor in water-based mud. PHPA LIQUID is not susceptible to bacterial attack. PHPA maintains viscosity in solid free drilling fluid. As a Bentonite extender in low solids non-dispersed mud, it can be used along with small addition of Bentonite to suspend weight material.
