“…Cultures of sulfate-reducing bacteria acquire relative resistance to toxic compounds, as a result of adaptation, which require higher doses of bactericide than those calculated for laboratory collection cultures to suppress the vital activity of sulfate-reducing bacteria in the bottom hole zone and reservoir (Kriel et al, 1993).…”

A new technology based on the existence and microbial utilization of the preformed volatile fatty acid content of the reservoir waters, prevents sulfate reduction by sulfate reducing bacteria by the competitive removal of the volatile fatty acids in the reservoir waters. A new microbial population is developed in the presence of nitrate which has the capabilities of producing in-situ products such as gases and polymers - all known recovery agents. Laboratory investigations demonstrate the versatility and potential of the system to alter microbial populations by subtle changes in the reservoir waters. Core flooding data show increased oil production. This novel approach to prevent and reduce sulfide while at the same time to increase oil recovery is termed "Biocompetitive Exclusion". A microbial liability in the field is turned to an advantage and offers the petroleum industry a low cost methodology for reservoir control and stimulation. Introduction Numerous oil reservoirs face premature abandonment as a consequence of increasing production costs associated with problems of poor sweep efficiency, reservoir souring, and iron sulfide (pyrite) deposition. In many cases the presence of sulfide is the result of microbial action, and industry is searching for a solution to prevent reservoir souring while increasing oil recovery. A new technology has been developed which turns a microbial problem in the field to an advantage by substituting an alternate microbial population which prevents and removes sulfide while producing in-situ products such as gases, polymers, and surfactants which an: known oil recovery agents. This novel methodology for reservoir control and stimulation is termed Biocompetitive Exclusion and uses the existing volatile fatty acid content of the reservoir fluids as the energy source for a microbial enhanced oil recovery system. Background The anaerobic environment of virgin oil reservoirs is not usually conducive to the growth of microorganisms, although there is some anecdotal evidence that microorganisms may be indigenous to virgin oil reservoirs. If oil degrading aerobic microorganisms were able to grow in oil reservoirs, oil would never be formed except transiently. However, small changes brought about by the penetration of the reservoir during drilling and production can cause rapid growth of microorganisms with a concomitant change in the reservoir ecosystem. Some of these changes can be detrimental, such as souring due to hydrogen sulfide formation. Significant populations of sulfate reducing bacteria occur. In reservoirs undergoing souring, these microorganisms may be supported by minerals native to the reservoir and simple dissolved organic material in the formation water. Often sulfate is absent from formation waters, and therefore, the growth of sulfate reducing bacteria is not favored. However, when waterflooding operations begin, new substances (such as sulfate) are introduced into the reservoir (especially if sea waterup volume and maintain pressure) and SRB then become active and powerful geochemical agents. This leads to souring of the field and results in lower quality crudes and higher operating costs. P. 171^
