Stimulation activities present unique challenges, demanding fluid rheologies not seen in other industries. Nouryon produces viscoelastic surfactant (VES) technologies that form worm-like micelles in depleted acids and saline brines to viscosify the various water-based fluids that can optimize the performance of acidizing operations. This allows for non-damaging solutions for acid diversion through our viscoelastic diverting agents and surfactant-based acid gelling agents. 

Nouryon sells VES products under three trade names:




These all provide significant performance benefits not possible with conventional polymer-based systems. In acidizing or acid fracturing applications, the products self-divert, with depletion creating optimized wormhole networks at temperatures up to 375°F.

They have also been used as non-damaging viscosifiers for hydraulic fracturing operations at elevated temperatures.
