Abstract
An acidizing formulation for use in the stimulation of hydrocarbon production is stable when packaged and stored as a single fluid for periods exceeding one year. The formulation contains a miscibility solvent which substantially prevents any phase separation between the constituents and lack of dispersion of the additives in the fluid.
