  • Inhibiting corrosion in gas wells
    Patent number: 11959016
    Abstract: A composition for inhibiting corrosion in gas wells includes a pyrazolopyridine derivative. The pyrazolopyridine derivative includes a pyridyl moiety, a first pyrazole moiety, a second pyrazole moiety, and a phenyl moiety. The first pyrazole moiety is bound to the pyridyl moiety. The second pyrazole moiety is bound to the pyridyl moiety. The phenyl moiety is bound to the pyridyl moiety. The composition can be flowed into a wellbore formed in a subterranean formation, thereby inhibiting corrosion in the wellbore.
