  • Method of fracturing subterranean formations utilizing emulsions comprising acrylamide copolymers
    Patent number: 7482310
    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.
