  • Corrosion inhibition method for downhole metal tubing
    Patent number: 10988670
    Abstract: 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.
    Type: Grant
    Filed: February 20, 2020
    Date of Patent: April 27, 2021
    Assignee: KING FAHD UNIVERSITY OF PETROLEUM AND MINERALS
    Inventors: Ime Bassey Obot, Saviour Alphonsus Umoren
