        Acid Types Although many acid compounds are available to the oil industry, only the following types have been proven economically effective in oil well stimulation: Inorganic Acids (Strong). · Hydrochloric Acid (HCl). · Hydrofluoric Acid (HCl:HF). Other inorganic acids include Sulphamic, Sulphuric and Nitric acids. Organic Acids (Weak). · Acetic Acid and Glacial Acetic Acid. · Acetic Anhydride. · Citric Acid. · Formic Acid. Inorganic Acids Hydrochloric Acid (HCl). Hydrochloric acid is an inorganic acid and is the most commonly used acid in oil well stimulation. Hydrochloric acid has many advantages in its application as follows: · Low cost and availability. · Easily inhibited to prevent attack on oil-field tubulars.…
