The present disclosure generally relates to compositions and uses of sulfidogenesis inhibitor compounds of Formulae 1 and 2 for preventing sulfidogenesis, i.e., the reduction reaction of a sulfur-containing compound by sulfur-utilizing prokaryotes that produce sulfide species such as hydrogen sulfide, during enhanced oil recovery processes. A method for inhibiting or decreasing microbial sulfide production by sulfur-utilizing prokaryotes includes addition of an effective amount of sulfidogenesis inhibitor compounds of Formulae 1 and 2 to the fluid that is injected into a sulfidogenic reservoir system during enhanced oil recovery. For example, the compounds can be used as sulfidogenesis inhibitors in a water injection system for use in a hydrocarbon extraction system or a hydrocarbon production system. Thus, these compositions can be effectively used as inhibitors of biogenic hydrogen sulfide generation in oilfield fluids.
