Friction Reducers for High Brines

NEW Slik FR products provide superior friction reduction, even when using with saltwater or high brines. The new product line has been engineered to help reduce costs while providing superior results. These Slik FR products are based on fast-hydrating, highly-active AMPS co-polymer and are available in dry and liquid blended slurries for additional functionality.

DrySlik

– Reduces friction by up to 80%
– Smaller particle size hydrates rapidly even in low temperature
– Dramatically reduces the need for fresh water
– Tolerates high temperatures
– Simple equipment set up, requiring a dry feed system
– Eliminates hydration unit, and reduces trucking and driver time requirements by as much as 85%
– Eliminates hazardous solvents when combined with our custom non-emulsification chemistry

The following DrySlik dry friction reducers are available:

  1. DrySlik 3.0
    10% AMPS anionic copolymer, ideal for fresh and brackish water
  1. DrySlik 1235
    30% acrylic acid anionic FR, tolerant to medium brines
  1. DrySlik 3.5
    30% AMPS anionic copolymer, optimized for high salinity brines and produced water

Viscosity boosting additives are available to increase the low-end rheology.
