    摘要: Methods for treating formations bearing brine and at least one of black oil or volatile oil using a composition containing a nonionic polymer and solvent. The solvent at least one of solubilizes or displaces at least one of brine or oil in the formation. Methods for making a composition for treating a formation bearing brine an at least one of black oil or volatile oil are also disclosed.

    摘要: 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.
