Abstract
Systems and methods for neutralizing a hydrogen sulfide within a subterranean well include a hydrogen sulfide neutralizing tool having a tubular member. A tool shell circumscribes the tubular member, defining tool annular space between an outer diameter surface of the tubular member and an inner diameter surface of the tool shell. A sacrificial rod is located within the tool annular space and is formed of a material that produces metal sulfide when exposed to the hydrogen sulfide. An uphole perforation has an opening extending through a sidewall of the tubular member, defining a fluid flow path between the tool annular space and the internal bore of the tubular member. A downhole perforation is located downhole of the uphole perforation and hays an opening extending through the sidewall of the tubular member, defining a fluid flow path between the tool annular space and the internal bore of the tubular member.
