Abstract: Fluid treatment systems and compositions are provided including (a) at least one material including (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, viscoelastic surfactants, and mixtures thereof. The fluid treatment systems and compositions can be used to treat aqueous systems, for example as fracturing fluids for use in fracturing subterranean formations. Methods for inhibiting formation and/or precipitation of metal oxides in an aqueous composition using the fluid treatment systems or compositions also are provided.

Abstract: A method of treating a subterranean formation penetrated by a well bore including: (a) preparing a fracturing fluid containing a mixture resulting from: (I) providing a water-in-oil emulsion composition that includes: (i) 5% to 99% by weight of a water-in-oil emulsion polymer comprising a polymer or copolymer containing repeat units from an acrylamide monomer; (ii) 0.5% to 90% by weight of a carrier solvent; and (iii) 0 to 90% by weight of a fluidizing agent; and adding (iv) 0.1% to 10% by weight of one or more inorganic microparticles, where the total of all components is 100% by weight; and (II) adding the water-in-oil emulsion composition to water; and (b) contacting the subterranean formation with the fracturing fluid.
