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.
Claims4
A method comprising:
- flowing a composition into a wellbore formed in a subterranean formation, thereby inhibiting corrosion in the wellbore, the composition comprising a pyrazolopyridine derivative comprising:
- a pyridyl moiety;
- a first pyrazole moiety bound to the pyridyl moiety, the first pyrazole moiety comprising an R2 group selected from the group consisting of an alkyl group, a thiol group, a carboxyl group, an aromatic carbonyl group, a hydroxyl group, a methyl amino group, an amide group, and an ester group;
- a second pyrazole moiety bound to the pyridyl moiety, the second pyrazole moiety comprising an R3 group selected from the group consisting of an alkyl group, an amide group, an amino group, a thiol group, a hydroxyl group, an ester group, and a carboxyl group;
- and
- a phenyl moiety bound to the pyridyl moiety;
- and
- producing a hydrocarbon from the subterranean formation via the wellbore.
