Compositions comprise nonionic fluorinated polymeric surfactants and solvent. The solvent comprises: at least one of a polyol or polyol ether, wherein the polyol and polyol ether have from 2 to 25 carbon atoms; and at least one monohydroxy alcohol, ether, or ketone having from 1 to 4 carbon atoms, or a mixture thereof, wherein the solvent is capable of at least one of solubilizing or displacing brine or condensate in the hydrocarbon-bearing clastic formation. Embodiments of the compositions are useful in recovery of hydrocarbons from hydrocarbon-bearing clastic formations that contain brine and/or condensate. |
