PHPA polymers are drilling fluid additives that help stabilize shales in the wellbore. Protective colloidal particles act as shale stabilizers， cuttings stabilizers， and wellbore stabilizers. By bonding on site， these colloids "inhibit" dispersion of formation solids into the drilling fluid system. The necessary supplies and reagents needed to determine the free polymer available to absorb into the wall of the hole is contained in this kit. The test procedure also provides a simple and effective way of determining the concentration of anionic (negative) polyacrylamide polymer in sludge dewatering effluent， water， and wastewater treatment.
