Increased costs in exploring and developing frontier areas have resulted in greater emphasis in enhanced oil recovery methods. Since the location is known and most of the field equipment and the facilities are in place, microbes will enhance the recovery.

An average of seventy percent of reservoir oil is left after secondary and primary recovery. Therefore, developing effective oil recovery methods to produce the trapped oil enhances the project scope. All conventional chemical flooding methods are expensive. In contrast, microbial enhanced oil recovery (MEOR) involves injecting a small amount of microorganisms in solution to propagate through the reservoir and subsequently produce desirable chemicals. and gases that will enhance oil recovery and therefore profit.
