Microbial enhanced oil recovery research
The objective of this work is to develop an engineering framework for the exploitation of microorganisms to enhance oil recovery. Specific goals include: (1) investigation of the mechanisms of microbially induced oil mobilization; (2) the production, isolation, chemical characterization and study of the physical properties of microbially produced surfactants; (3) model studies in sandstone cores for the characterization of the interactions between growing microbially cultures and oil reservoirs; (4) development of simulators for MEOR; and (5) design of operational strategies for the sequential injection of microorganisms and nutrient in reservoirs are: (1) systematic discussion of the mechanisms important in MEOR processes; (2) Measurement of the growth characteristics of Bacillus Licheniformis under various conditions of pH, temperature and salt concentration for both aerobic and anaerobic growth.; (3) measurement of interfacial tension reducing ability of the biosurfactant under different conditions of pH and salt concentration; (4) development of some preliminary methods to concentrate and characterize the biosurfactant; (5) development of a compositional numerical simulator for MEOR processes; and (6) Measurement of the lowest interfacial tension (IFT) value reported for biosurfactants to date. Demonstration of the fact that the low IFT values required for oil recovery can be attained with biosurfactants.
