| Abstract | SummaryCorrosion failure of the Pembina pipeline system of North Central Alberta, Canada, was frequent and was associated with constant bacterial load and sulphide in the crude oil and produced water. The bacterial load included a variety of anaerobic and aerobic/facultative bacteria which acted in concert to produce sulphide, giving rise to a “cascade of sulphide generation”.A total of 256 isolates from the crude oil were tested for ability to reduce oxidized sulphur compounds to sulphide. Five groups of bacteria, (A-E), based on this ability to reduce sulphur compounds, existed in the crude oil system. Group A reduced sulphur compounds with oxidation states +6; and lower, Group B reduced oxidation state +4 and below; Group C, oxidation states +2 and lower. Group D reduced only oxidation state 0 (elemental Sulphur), while Group E could reduce no sulphur compound to sulphide. It was found that a ceiling on the reductive capability of each bacterial group was set by the oxidation state of the sulphur compounds. The result is a synergistic relationship whereby intermediate products of reductive activities of each group form the substrate for subsequent action by other groups until sulphide is produced. |
