Abstract:
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.

Claim (Index 18):
The method of  claim 2  wherein the VES has a structure in accordance with Formula III: in which R 1  is a hydrocarbyl group that may be branched or straight chained, aromatic, aliphatic or olefinic and contains from about 17 to about 26 carbon atoms and may include an amine; R 2  is hydrogen or an alkyl group having from 1 to about 4 carbon atoms; R 3  is a hydrocarbyl group having from 1 to about 5 carbon atoms; and Y is an electron withdrawing group.
