Abstract:
A water-in-oil emulsion having an oil phase (O) and an aqueous phase (A) at an O/A ratio of from about 1:8 to about 10:1; wherein the water-in-oil emulsion includes the oil phase as a continuous phase that includes an inert hydrophobic liquid, and the aqueous phase as a dispersed phase of distinct particles in the oil phase that includes water, a water soluble polymer, and at least one surfactant; wherein the water soluble polymer includes from about 1 to about 60 weight percent of one or more cationic monomers, wherein the amount is by total weight of the water soluble polymer; wherein the water soluble polymer is present in an amount from about 5 to about 40 weight percent of the water-in-oil emulsion; and wherein an aqueous solution prepared by inverting the water-in-oil emulsion by adding it to water has at least comparable viscosity build to an aqueous solution made from a water-in-oil emulsion of the same composition containing 15 weight percent more water soluble polymer. Also provided is a method of treating a portion of a subterranean formation that includes the steps of: (a) providing a water-in-oil emulsion according to the present disclosure; (b) inverting the water-in-oil emulsion by adding it to water at from about 0.1 to about 5 gallons of water-in-oil emulsion per thousand gallons of water to form a friction reducing treatment solution containing from about 0.0005 weight percent to about 0.12 weight percent water soluble polymer based on the weight of the treatment solution; and (c) introducing the treatment solution into the portion of the subterranean formation.

Claim (Index 7):
The water-in-oil emulsion according to  claim 3 , wherein the water-in-oil emulsion comprises ammonium salt, 4-methoxyphenol, and an ethoxylated C 12 -C 16  alcohol; and wherein the inert hydrophobic liquid comprises a mixture of paraffinic hydrocarbons and napthenic hydrocarbons; and wherein the surfactants comprise a tall oil fatty acid diethanol amine, a polyoxyethylene (5) sorbitan monooleate, and a sorbitan monooleate; and wherein acrylamide is present in the water soluble polymer in an amount from about 10 weight percent to about 99 weight percent, wherein the amount is by total weight of the water soluble polymer.
