ABSTRACT:
The present invention is a bacteria and its use in a Microbial Enhanced Oil Recovery (MEOR) process. Any one of two newly isolated strains of bacteria are injected downhole in a petroleum reservoir to modify its profile. This bacteria has the capability to plug the zones of higher permeability within the reservoir so that a subsequent waterflood may selectively enter the oil bearing less permeable zones. The injected water is used to drive this oil to an area where it may then be recovered.
