摘要： Methods are provided for detection of souring or the likelihood of souring in an oil and gas process fluid which involves analysis of an aqueous sample obtained from an oil and gas process fluid for the presence of bacteria of at least two different bacterial genera, wherein the genera are selected from Pelobacter, Flexistipes, Marinobacterium, Geoalkalibacter, and Halanaerobium. The presence of bacteria from two or more said genera indicates the likelihood of increased sulfide production in the fluid. Other related methods and reagent compositions for performing the methods are provided.
