    Abstract: Compositions and methods for oil recovery using a surfactant-less alkaline-polymer system in hard water or hard brine is described in the instant invention. The formulation further includes a chelating agent, an alkaline agent (which can be the same as the chelating agent), and a co-solvent. The formulations as disclosed herein are capable of forming a surfactant in-situ resulting in Winsor Type III micro-emulsions of low interfacial tension.

    Abstract: The present invention includes a method for treating a hydrocarbon-bearing clastic formation having brine. The method includes contacting the hydrocarbon-bearing clastic formation with a fluid, which at least one of at least partially solubilizes or at least partially displaces the brine in the hydrocarbon-bearing clastic formation, and subsequently contacting the hydrocarbon-bearing clastic formation with a composition. The composition includes a nonionic fluorinated polymeric surfactant and solvent. When the composition is contacting the hydrocarbon-bearing clastic formation, the nonionic fluorinated polymeric surfactant has a cloud point that is above the temperature of the hydrocarbon-bearing clastic formation.
