Abstract: The invention includes a method of reducing a need to re-acidize a hydrocarbon-containing formation. The method comprises providing a composition a HCl and lysine mixture and water wherein a molar ratio between the HCl and the lysine mixture ranges between 3:1 and 12.5:1, and the composition has an initial pH of less than 1; injecting the composition into the formation; allowing a sufficient time for the composition to become a spent acid composition and to subsequently create wormholes in the formation by dissolving calcium carbonate in the formation; maintaining the dissolved calcium carbonate in suspension in the spent acid composition to prevent reprecipitation of the calcium carbonate into the wormholes; removing the spent acid composition containing the dissolved calcium carbonate from the formation; and wherein a pH of the spent acid composition ranges between 4 and 6.
