- Oil reservoirs naturally contain inorganic and organic materials which can be exploited through simple supplementation to support the growth of microorganisms which aid in the release of oil from the rock matrix. Other compounds which may serve as nutritional sources for microorganisms are added to reservoirs during production and operation of oil fields. These materials include sulfate, nitrate, carbonate, volatile fatty acids, nitrogen-containing corrosion inhibitors, phosphorous-containing scale inhibitors and trace elements. Our experiments show that, with minimal supplementation, growth of naturally-occurring microorganisms can be used to produce viscosifying agents to aid oil recovery. This natural microflora is also capable of removing sulfide from oil reservoirs and preventing the formation of new sulfide leading to both more oil recovery and increased value of the produced oil. The metabolic products of these microorganisms are Co₂, water, N₂ and oxidized forms of sulfur, all of which are environmentally innocuous. Laboratory experiments with both defined mixtures of microorganisms as well as mixed populations both release more oil from sand pack columns.
