Methods and systems of clean-up for a fracturing fluid

A system of fracturing fluid cleanup in a subterranean region of interest, the system comprising:

• a mixing system configured to:
• emulsify a first emulsion,
• wherein the first emulsion comprises:
• a first aqueous phase,
• a first hydrocarbon phase, and
• a first surfactant;
• and
• emulsify a second emulsion,
• wherein the second emulsion comprises:
• a second aqueous phase,
• a second hydrocarbon phase, and
• a second surfactant;
• and
• a hydraulic fracturing system operatively connected to the mixing system and configured to:
• pump the first emulsion into the subterranean region of interest;
• and
• pump the second emulsion into the subterranean region of interest after a pre-determined time,
• wherein heat and a gas are generated from a reaction of mixing of the first emulsion and the second emulsion,
• wherein the first emulsion is destabilized by the heat of the reaction, and
• wherein the gas reduces hydrostatic pressure to facilitate flowback of the first emulsion.
