Contamination of crude oil and fuel gas with hydrogen sulfide decreases the value of the product and increases refining costs. Injection of seawater into oil field reservoirs for secondary oil recovery is a common practice. However, seawater contains sulfate and other substances essential for bacterial growth, eventually growth requirements of sulfate-reducing bacteria; are met, resulting in the production of hydrogen sulfide. This paper presents results on substrate characterization for microbial consortia from two oil field reservoirs at a temperature range of 35 to 75 C. The competition of sulfate-reducing bacteria and other groups of microorganisms is discussed. 38 refs., 3 figs., 3 tabs.
