Patent ID: 8043998

Claim:
A method of treating a hydrocarbon-bearing formation having at least one fracture, wherein the fracture has a volume, and wherein the fracture has a plurality of proppants therein, the method comprising: contacting the fracture with an amount of a composition, wherein the amount of the composition is based at least partially on the volume of the fracture, wherein the composition comprises solvent and a nonionic fluorinated polymeric surfactant, and wherein the nonionic fluorinated polymeric surfactant comprises: at least one divalent unit represented by formula: a poly(alkyleneoxy) segment wherein R f represents a perfluoroalkyl group having from 1 to 8 carbon atoms; R and R 2 are each independently hydrogen or alkyl of 1 to 4 carbon atoms; and n is an integer from 2 to 10; allowing the nonionic polymeric fluorinated surfactant to interact with at least a portion of the plurality of proppants.
