A method of inhibiting corrosion of metal during acid stimulation of an oil and gas well, whereby the oil and gas well is treated with an acidic treatment fluid that includes 10 to 28 wt. % of an acid, based on a total weight of the acidic treatment fluid, and 0.01 to 5% of a pyrazine corrosion inhibitor by weight per total volume of the acidic treatment fluid, wherein the pyrazine corrosion inhibitor is 2,3-pyrazine dicarboxylic acid, pyrazine-2-carboxamide, 2-methoxy-3-(1-methylpropyl) pyrazine, or combinations thereof. |
