The program was composed of three areas: Task 1-Phase Behavior and Fluid Property Measurements, Task 2-Mixing of CO2 and Oil During Flow in Reservoir Rocks, and Task 3-Mobility Control in CO2 Floods. In Task 1, the continuous phase equilibrium apparatus was used to measure simultaneously the viscosity, density, and composition of CO2 -hydrocarbon systems at high pressure. In Task 2, the performances of secondary and tertiary displacements of crude oil by CO2 in cores were measured and compared to predictions made with a multi-component, one-dimensional simulator. In Task 3, procedures and equipment were developed to measure the steady-state mobility of foam-like dispersions of dense CO2 in surfactant solutions. 72 refs., 116 figs., 31 tabs.
