Abstract
A treatment fluid that includes an aqueous fluid, an inorganic acid, and a hydrophobically modified quaternized polysaccharide may be useful in mitigating corrosion of metal surfaces by the inorganic acid. For example, a wellbore operation may include introducing the treatment fluid into a wellbore penetrating a subterranean formation and contacting a metal surface with a treatment fluid.
