Figure 5 shows the residual oil saturation as a function of pore volume injected for the same simulations. The mixed-wet system with the parameters described in Sayed et...

..., no additional oil was recovered during water injection periods. Therefore, no meaningful linear relationship was observed between three-phase residual oil saturation and trapped gas saturation. Under immiscible conditions, gravity-stable gas injection recovered more than 45% of IOIP. In comparison...

... were performed on the SAMA test well (Well A) to measure the effectiveness of ASP injection in mobilizing waterflood residual oil saturation. The first SWCT test (Test #1) measured the waterflood residual oil saturation (Sorw) after a 10 PV seawater injection. This was followed by the second SWCT test...
