摘要 |
The present invention includes compositions and method for treating a hydrocarbon-bearing clastic formation having brine, the method comprising: contacting the hydrocarbon-bearing clastic formation with a fluid, wherein the fluid 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 comprising: a nonionic fluorinated polymeric surfactant, and solvent, wherein 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. |
