Fluid Treatment Systems, Compositions and Methods for Metal Ion Stabilization in Aqueous Solutions and/or Enhanced Fluid Performance

A method of inhibiting formation of metal oxides in an aqueous composition comprising at least 20 milligrams of metal ions per liter of aqueous composition, comprising:

• mixing an aqueous composition comprising metal ions with a fluid treatment system comprising:
• (a) at least one material comprising (1) at least one carboxylic acid functional group and (2) at least one sulfur-containing group selected from the group consisting of sulfonyl functional groups, sulfonate functional groups and mixtures thereof;
• and
• (b) at least one friction reducing agent selected from the group consisting of guar gums, polyacrylamides, hydratable cellulosic materials, visco elastic surfactants, and mixtures thereof.
