Abstract
A hydration acceleration surfactant may be utilized in conjunction with high molecular weight polymers in forming high viscosity, aqueous based treatment fluids. Forming such fluids may involve mixing an aqueous base fluid, a hydration acceleration surfactant, a crosslinker polymer, and a base polymer, thereby yielding a treatment fluid, wherein the base polymer is provided in the form of a first polymeric emulsion before mixing and/or the crosslinker polymer is provided in the form of a second polymeric emulsion before mixing. Further, such fluids may be useful in subterranean operations to perform for at least one function within the wellbore and/or the subterranean formation including bridge a fracture, provide fluid loss control, seal a rock surface, enable fluid diversion, plug a void, reduce formation permeability, control water production, and any combination thereof.
