NewPac™ PLV filtration control agent is a premium, low-viscosity grade, polyanionic, cellulosic polymer. It is effective in fresh or saltwater to control fluid loss and maintain thin filter cakes without building excessive viscosity. The product is an effective coating agent that protects hydratable solids from dispersion. NewPac PLV cellulosic polymer is resistant to bacterial degradation.
NewPac PLV filtration control agent is highly effective in controlling fluid loss in water-based drilling fluids when an increase in viscosity is undesirable.
NewPac PLV filtration control agent is ideal for use in all types of water-based drilling fluids, including salt-saturated systems. It is an excellent polymer for filtration control in low-solids and dispersed fluids.
Used in concentrations of 0.25-2.0 lb/bbl, the product can be mixed directly through the hopper, but must be added slowly to prevent balling and possible loss of product over the shaker. It can be added through the chemical barrel by dispersion in diesel or synthetic oil; however, some type of agitation is required in the barrel to prevent settling. Product effectiveness will decrease with bottomhole temperatures above 300°F (149°C) and as soluble calcium increases, which would possibly require higher treatment levels. In salt-saturated systems, some starch may be required to achieve best results.

Handling and Storage
NewPac PLV polymer is extremely slippery when wet. Use caution if spilled. Minimize exposure to dust. Store in a cool, dry, well-ventilated area. Keep container tightly closed. Use appropriate hygiene, clothing and personal protective equipment suitable for the work being done. Review the SDS thoroughly before using this product.
NewPac PLV filtration control agent is available in 50-pound (22.7-kilogram) multi-walled bags.
