Resinated lignite filtration control agent
Product Description
CORE-RESO is designed to provide filtration control over a wide range of temperatures and in the presence of contaminants. CORE-RESO is a temperature-stable, synthetically formulated resin and lignite complex which has proven to be one of the most effective high-temperature filtration-control additives available.
CORE-RESO is a broad-application fluid loss-control agent that can be used in virtually any water-base mud. In field applications, excellent results have been obtained in freshwater, brackish water, seawater, saltwater, lime, gyp, lignosulfonate, polymer and non-dispersed systems. It also stabilizes and extends the temperature limitations and contamination resistance of water-base mud systems to above 400°F (204°C). It is notably effective in high-density muds where fluid-loss control can be achieved without increases in viscosity.

The product is designed to have a minimal effect on the viscosity of most mud systems; however, CORE-RESO may reduce the viscosity of non-dispersed systems.
