Provided is a composition that may include a fluid formulation that is a water-in-oil emulsion, having an organic phase and an aqueous phase, the aqueous phase dispersed in the organic phase. The organic phase may include an organic solvent, an emulsifier, and a wetting agent. The aqueous phase may include water, a chelating agent, and a base. Further provided is a method that may include introducing the composition into a wellbore as a single stage treatment, maintaining the wellbore by shutting-in the well, and hydraulic fracturing the wellbore.
