Abstract:
A method of inhibiting corrosion of metal during acid stimulation of an oil and gas well that involves treating the oil and gas well 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 a corrosion inhibitor composition containing gelatin, wherein the gelatin is present in the acidic treatment fluid in a concentration of 0.1 to 10% by weight per total volume of the acidic treatment fluid.
