    摘要: The present invention relates to the use of surface-modified nanoparticles to alter the morphology and microstructure of polymer blends. The addition of surface modified nanoparticles to polymer blends comprised of immiscible polymers facilitates the uniform distribution of the dispersed phase of the polymer blend. In an embodiment, the present invention relates to a polymer blend comprising (1) a continuous phase comprising at least one polymer, monomer or oligomer, and a plurality of surface-modified nanoparticles, having a particle diameter of less than about 100 nanometers, distributed in the continuous polymer phase; and (2) a dispersed phase comprising at least one polymer, monomer or oligomer, wherein the continuous polymer phase and the dispersed polymer phase are immiscible.

    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.

    摘要: Methods of treating a hydrocarbon-bearing formation having brine and liquid hydrocarbons and treated hydrocarbon-bearing formations. The methods include contacting the hydrocarbon-bearing formation with a composition comprising solvent and a fluorinated anionic surfactant. In some embodiments, the solvent solubilizes the brine in the hydrocarbon-bearing formation without causing the fluorinated anionic surfactant to precipitate. In some embodiments, the solvent includes at least one of a polyol or polyol ether independently having from 2 to 25 carbon atoms and at least one of water, a monohydroxy alcohol, an ether, or a ketone, wherein the monohydroxy alcohol, the ether, and the ketone each independently have up to 4 carbon atoms.
