Description
Vitória da Silva Pereira Domingues and co-authors track sour gas in the water systems of an offshore oil platform in Brazil. Operators inject seawater and recycled produced water to push oil out. Microbes in that water make hydrogen sulfide, which corrodes steel and sours the reservoir. Sulfate-reducing bacteria are the usual suspects.
Produced water carried the highest sulfide levels. It crossed the safety threshold in about a fifth of samples. The reinjection water crossed it in about a sixth. Simple microbe counts did not track the gas. DNA methods told the story better: one bacterial group, Desulfobacterota, dominated the produced and reinjected water. The cleaning step, flotation, seemed to enrich the very microbes operators fear.
