Abstract (en)

[origin: WO2011012164A1] A method of fracturing subterranean formations which comprises using a low residue fluid that facilitates the clean up of the wellbore following the treatment is disclosed. The system includes a surfactant compound that forms micelles above a critical concentration. Under certain conditions the addition of an associative thickener compound yields a network based on hydrophobic interactions. The resulting viscous fluid can transport proppants, be applied neat or as a foamed or energized system, or used in an acidizing treatment. The method may further include a breaking step.
