Improved bacteria-busting techniques could make oil extraction greener, cheaper

Easy-to-implement, cost-cutting measures – such as adjusting the water temperature used during oil production – could offer a way of tackling problems linked to sulphate-reducing bacteria (SRB) that is greener and more effective than those currently relied on. SRB ‘breathe’ sulphates but exhale toxic, corrosive hydrogen sulphide (H2S).
