Abstract
The present invention relates to fluids useful for subterranean operations, and more particularly, to fluorosurfactants useful for the reduction of water blocks, gas blocks, and/or gas condensates and their associated treatment fluids and methods. Provided is a method of treating a subterranean formation. The method may comprise contacting the subterranean formation with a fluorosurfactant. The fluorosurfactant may comprise an amine group, wherein the amine group comprises at least one substituent selected from the group consisting of a fluoroalkyl group, a fluoroalkenyl group, and combinations thereof, wherein the at least one substituent comprises about 3 carbons to about 22 carbons. Also provided are polymeric surfactants and treatment fluids that comprise fluorosurfactants.
