The Hydra STAB stabilizer is a highly concentrated inhibitor of shales on the basis of choline chlorides. It has no negative impact on rheological properties of frac fluid. Hydra STAB is compatible with polymers, lubricating agents, and surfactants. Concentration of the given reagent from 1.0 to 2.0 l/m3 provides inhibiting of shales, similar to 2% solution of KCl.
Recommended concentration of the Hydra STAB stabilizer in frac fluid should be from 1 to 2 l/m3. Is efficient at temperatures up to 170 °С.
