“…Till date, various methods have been developed for detecting H 2 S, including gas chromatography, electrochemical methods, colorimetric methods, and polarographic sensors [12][13][14][15][16][17]. However, in virtue of the high diffusible and reactive properties of H 2 S, it is not appropriate for real-time detection of H 2 S with the traditional detection technologies.…”

“…3,24,25 Sulfide anion can act as a versatile intermediate through which sulfur with other species can be determined, since their high reactivity provides various means of detection. [27][28][29][30][31][32][33][34][35][36][37][38][39] In this sense, the coupling of flow injection analysis (FIA) with different detection strategies can be considered to be a good alternative for sulfide determination. Such a feature is assured to be due to outstanding advantages of the FIA system, such as simplicity, little sample manipulation, low reagents and sample consumption and, consequently, low-waste outcome.…”

The injection of sulfate-containing seawater into an oil reservoir, for maintaining the reservoir pressure, can promote the growth of sulfate reducing bacteria and archaea near the injection wells, leading to the formation of sulfides such as hydrogen sulfide. However, intermediate sulfur species with different valence states, such as polythionates and polysulfides have been detected in several produced water samples, likely a result of phase partitioning, and chemical and microbial reactions. These sulfur species could affect the microbial communities (e.g., microbially influenced corrosion) and will impact the efficiency of souring mitigation methods. In addition, the presence of these sulfur species can result in operational, environmental, and treatment problems. Therefore, development and implementation of souring control strategies during production cycle of oil and gas reservoirs require identifying the origins, reactivity, and the partitioning behaviour of these compounds. This paper presents an overview of the known mechanisms responsible for reservoir souring and then focuses on the chemical reactions and sulfur species associated with production and consumption of hydrogen sulfide. In this work we highlight complexity of the sulfur chemistry and that the assumption that all the sulfate is reduced to hydrogen sulfide can lead to inappropriate souring management methods. The paper also reviews the detection and analysis methods used for sulfur compounds. The review demonstrates that there is a gap in the current souring models and methods due to the exclusion of key sulfur compounds and challenges in identifying and quantifying these compounds with respect to speed of analysis and sample stability.
