Abstract: Compounds comprising multiple hydrophilic heads and a lipophilic tail may be contacted with a metal or other surface so as to adhere to the surface and inhibit corrosion, among other things. Suitable hydrophilic heads may include quaternary ammonium cation moieties, phosphonium cation moieties, and combinations thereof. Such corrosion-inhibiting compounds may be introduced into a wellbore penetrating at least a portion of a subterranean formation, for instance in oil and/or gas recovery operations and the like, whereupon the compound may adhere to a metal or other surface downhole so as to inhibit corrosion of the surface. These compounds may be employed in various other environments, such as any metal or other surface that may be exposed to corrosive conditions.
