Flowback Aid for Acid

Acid-fracturing flowback aids are used in acid-fracturing operations. The acid fluid that invades the reservoir may have slow or difficult flowback due to the retention effect or the liquid-phase aggregation effect, which will aggravate the damage to the reservoir. Therefore, in order to accelerate the flowback rate of the spent acid in the formation, it is necessary to add flowback aids to the fracturing fluid to reduce the surface-interface tension of the spent acid and improve the flowback effect.
