Microbial Chlorate Reduction as a Control of Biogenic Hydrogen Sulfide Production in Oil Reservoirs

The generation of hydrogen sulfide (H2S) as a metabolic end product of microbial sulfate respiration results in a variety of oil recovery problems, including oil reservoir souring, contamination of crude oil, and metal corrosion.  It may be possible to control the generation of biogenic H2S through the activity of sulfur-oxidizing bacteria. Coates will determine the ability of chlorate-reducing bacteria to inhibit and reverse microbial sulfate reduction, to identify the environmental and biological parameters under which this occurs, and to demonstrate that suitable chlorate-reducing populations are indigenous to oil reservoirs.
