1. A method of increasing recovery of hydrocarbons from a hydrocarbon-containing subterranean fractured rock formation, the method comprising:
forming a flowback concentrate comprising a dimer surfactant and an anionic monomer surfactant;
contacting the flowback concentrate with a water source to form a flowback injectate, the flowback injectate comprising about 99 wt % to 99.999 wt % of the water source;
injecting the flowback injectate into the hydrocarbon-containing subterranean fractured rock formation; and
collecting a hydrocarbon from the hydrocarbon-containing subterranean fractured rock formation,
wherein the dimer surfactant comprises:,
