LYSINE: HYDROCHLORIDE SYNTHETIC ACID COMPOSITIONS AS ALTERNATIVES TO CONVENTIONAL ACIDS IN THE OIL AND GAS INDUSTRY.

摘要

An aqueous synthetic acid composition for use in oil industry activities, said composition comprising: 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; it can also further comprise a metal iodide or iodate; 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 oil and gas industry operations. Preferred embodiments of said composition providing substantial advantages in matrix acidizing by increasing the effectiveness of wormholing compared to conventional mineral acids such as HC1.
