    摘要: A method of treating a hydrocarbon-bearing formation that includes receiving data comprising a temperature and a brine composition of the hydrocarbon-bearing formation; selecting a treatment composition for the hydrocarbon-bearing formation comprising a fluorinated compound and solvent, wherein, at the temperature, a mixture of an amount of the brine composition and the treatment composition separates into at least two separate transparent liquid layers, and wherein the mixture is free of precipitated solid; and contacting the hydrocarbon-bearing formation with the treatment composition. Compositions containing certain fluorinated polymers and solvents containing water, monohydroxy alcohols, and ketones are also disclosed.
