Microbial strains and products for mobility control and oil displacement: Final report for the period July 1, 1980-February 28, 1986
The objective of this work was to demonstrate that microorganisms and their products can enhance the recovery of oil from heterogeneous reservoirs. The particular focus of research has been on in situ processes including selective plugging to remedy permeability stratification. Using various experimental models of porous media, the feasibility of microorganisms to enhance oil recovery was systematically studied. It has been shown that many of the potential problems facing the application of microbial processes can be overcome. Topics discussed in the report are as follows: The effect of sterilization method on bacterial penetration through Berea sandstone; in-situ microbial growth and metabolism in Berea sandstone; selective plugging and oil displacement in crossflow core systems by microorganisms; effect of nitrate on biogenic sulfide production; characterization of polymer-producing bacteria; and the purification and properties of the biosurfactant produced by Bacillus Licheniformis Strain JF-2. 199 refs., 23 figs., 13 tabs.
