Gas miscible displacement enhanced oil recovery
The general goal of the Gas Miscible Displacement Project is to support high-risk, long-term CO/sub 2//EOR research that does not duplicate or displace private and other public R and D efforts. More specifically, the project goals are: (1) to understand the CO/sub 2/ process displacement mechanisms; (2) to provide predictive capability to forecast recovery from the process; and (3) to improve the process recovery efficiency. In order to accomplish these goals, the following research priorities have been identified: (1) better mobility control of injected fluids; (2) improved techniques for reservoir evaluation through investigating geologic and reservoir heterogeneity, residual oil saturation, and fracturing; (3) improved understanding of oil swelling, viscosity reduction, and extraction/vaporization phenomena; (4) improved predictive modeling; and (5) field-performance appraisal for tertiary oil recovery. The objectives of the research for FY 83 and FY 84 are: to provide a better understanding of the mechanism of the carbon dioxide miscible displacement process; to increase the displacement and sweep efficiencies of the injected fluids; to provide predictive modelig capability for the gas miscible displacement process; and to study the effects of reservoir heterogeneity.
