SYNTHETIC ACID COMPOSITIONS OF LYSINE CHLORIDRATE AS ALTERNATIVES TO CONVENTIONAL ACIDS IN THE OIL AND GAS INDUSTRY

摘要

Lysine hydrochloride synthetic acid compositions, as alternatives to conventional acids in the oil and gas industry, are an aqueous synthetic acid composition for use in activities in the oil industry, said composition comprising: lysine and hydrogen at a molar ratio ranging from 1: 3 to 1: 12.5, preferably from more than 1: 5 to 1: 8.5; it may also comprise a metal iodate or iodide; an alcohol or derivative thereof.said composition demonstrates advantageous properties over known synthetic acids at temperatures above 90 ° C. Said composition is useful in various operations of the oil and gas industry. Preferred embodiments of said composition offer important advantages in matrix acidification by increasing the effectiveness of the flow channels compared to conventional mineral acids such as hydrochloric acid (hCl).
