ON THE FLY MIXING OF ACIDS AND DIVERSION FLUIDS WITH WATER-SOLUBLE RETARDING AGENTS

摘要

Described herein are methods for on the fly mixing of retarded acidizing fluids containing acid, a water-soluble acid retarding agent (RA), and optionally a viscoelastic surfactant (VES), and for on the fly mixing of diversion fluids containing VES and RA in the same equipment. Also described are methods of controlling the preparation of such fluids based on feedback composition analyses.
