PAC R
Description
PAC R is a premium grade purified high viscosity, high molecular weight, Polyanionic Cellulose polymer designed to provide viscosity and reduce API filtration rate to water based drilling fluids.
|
Application & Features
PAC R is a cost-effective additive to reduce API filtration rate of many water based drilling fluids including freshwater, seawater, saturated saltwater and solids-free brines, native mud, flocculated mud, inhibited mud and contaminated systems.
PAC R increases and stabilizes viscosity to improve rheology, wellhole cleaning and suspension property by coating and encapsulating cuttings and solids of drilling fluids.
PAC R is effective over a wide range of pH environments. It lubricates solids in the system, improve wallcake characteristics and reduces the potential for stuck pipe.
