| Property | Secondary injection schemes |
||
|---|---|---|---|
| WF | SP blend | Comments | |
| Initial oil saturation (S oi) | 0.69 | 0.67 | Similar drainage cycles |
| VPInj up to BT | 0.07 | 0.26 | Breakthrough delay: mobility control |
| RF up to BT | 10.1 | 38.5 | IFT reduction and displacement efficiency improvement |
| PVinj up to W cut of 80% | 1.5 | 2.46 | Water production management |
| RF up to W cut of 80% | 40.8 | 71.8 | IFT reduction and displacement efficiency improvement |
| PVinj up to W cut of 95% | 9.6 | 9.96 | Similar behavior at high quantities of injected fluids |
| RF up to W cut of 95% | 56.8 | 0.75 | IFT reduction and displacement efficiency improvement |
| RF at final of the test | 57.8 | 0.75 | SP blend usage improves the process efficiency |
| Residual oil saturation (S or) | 0.29 | 0.17 | High oil saturation reduction (40% lower) |
