| titleOfInvention | Copolymer surfactants for use in downhole fluids |
| abstract | Various embodiments disclosed relate to hydroxy-terminated poly(alkylene oxide) copolymer surfactants for use downhole, downhole compositions including the same, and methods of using the same. In various embodiments, the present invention provides a method of treating a subterranean formation. The method can include obtaining or providing a composition including a hydroxy-terminated poly(alkylene oxide) copolymer surfactant. The copolymer surfactant can include a first repeating unit having the structure -[R1O]-, wherein at each occurrence R1 is independently a substituted or unsubstituted (C2-C10)alkylene group. The copolymer surfactant can include a second repeating unit having the structure -[R2O]-, wherein at each occurrence R2 is independently a substituted or unsubstituted (C2- C10)alkylene group. The first repeating unit can have a lower molecular weight than the second repeating unit. The first repeating unit and the second repeating unit can have a random copolymer or block copolymer arrangement in the copolymer surfactant. The method can also include placing the composition in a subterranean formation downhole. |
