摘要:
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.

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.
