摘要
Systems and methods for creating surfactant-polyelectrolyte complexes at a well site are provided. In one embodiment, the methods comprise: providing a first solution comprising at least one surfactant and a second solution comprising at least one polyelectrolyte; using a stop-flow mixing apparatus at a well site to mix the first and second solutions to form one or more surfactant-polyelectrolyte complexes; using a low-dose pumping apparatus at the well site to transfer the one or more surfactant-polyelectrolyte complexes from the stop-flow mixing apparatus to a blending apparatus at the well site; using the blending apparatus to mix the one or more surfactant-polyelectrolyte complexes with an aqueous base fluid to form a treatment fluid; and introducing the treatment fluid into a well bore penetrating at least a portion of a subterranean formation at the well site.
