Enhanced oil recovery (EOR) via carbon dioxide (CO2) flooding has received a considerable amount of attention as an economically feasible method for carbon sequestration, with many recent studies focus- ing on developing enhanced CO2 foaming additives, However, the potential long-term environmental effects of these additives in the event of leakage are poorly understood and, given the amount of additives injected in a typical CO2 EOR operation, could he far-reaching, This paper presents a summary of recent developments in surfactant and surfactant/nanoparticle-hased CO2 foaming systems, with an emphasis on the possible environmental impacts of CO2 foam leakage, Most of the surfactants studied are unlikely to degrade under reservoir conditions, and their release can cause major negative impacts on wildlife, With recent advances in the use of additives (e,g,, nonionic surfactants, nanoparticles, and other chemicals) the use of harsh anionic surfactants may no longer he warranted, This paper discusses recent advances in producing foaming systems, and highlights possible strategies to develop environmentally friendly CO2 EOR methods, 展开更多
