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.

Using synthetic acid compositions as alternatives to conventional acids in the oil and gas industry

An aqueous synthetic acid composition for use in oil industry activities comprises lysine and hydrogen chloride in a molar ratio ranging from 1:3 to 1:12.5, preferably from more than 1:5 to 1:8.5. The composition can also further comprise a metal iodide or iodate; an alcohol or derivative thereof. The composition demonstrates advantageous properties over known synthetic acids at temperatures above 90&#xb0; C. The composition is useful in various oil and gas industry operations. Preferred embodiments of the composition provide substantial advantages in matrix acidizing by increasing the effectiveness of wormholing as compared to conventional mineral acids such as HC1.
