The Rapid Sweep polymer stick contains a measured quantity of acrylic copolymer in a water-soluble package. It is designed to provide viscosity, reduce friction, encapsulate cuttings, and maintain a limited amount of fluid-loss control in water-base drilling fluids—while at the same time providing a simple way to add copolymer to the drillstring during connections and delivering a consistent method of cleaning the wellbore.

The Rapid Sweep polymer stick contains a specially-treated acrylic copolymer that can be used in most lightly-treated, low weight water-base mud systems.
