... on the casing of a well in the Eagle Ford region. One well was exposed to a reservoir that is known to contain acetic acid (149-306 ppm) and CO 2 (1 mol%). Acetic acid is known to accelerate corrosion rates 1-4 and disrupt the protective nature of an iron carbonate films at elevated temperature. 5...

... shown that the pH in the above buffer solution is based on molarity ratio of [CH 3 COOH]/[CH 3 COO - ], and the stability of each buffer depends on magnitude of molar concentration of acetic acid and/or acetate. In other words, buffer solution is more stable in rich-rich pair of acetic acid and acetate...
