A viscoelastic emulsion formed by combining at least one extended surfactant, a salt (e.g., brine), an oil, such as crude oil, diesel, kerosene, or a vegetable oil, and water, into a mixture comprising an oil-starved Winsor III microemulsion into which excess oil is dispersed. The viscoelastic emulsion may be combined with a proppant to form a fracking fluid. The viscoelastic emulsion may be used in various reservoir applications, such as hydraulic fracturing, or flooding for enhanced tertiary oil recovery, and in other applications such as, but not limited to, environmental remediation, or formation of consumer products.
