Table 2
Oil recoveries of different displacement stage in homogeneity core sample.
| Scheme | Oil recoveries in water flood stage % | Oil recoveries in chemical flood stage, % | Incremental recoveries, % |
| 0.65 PV of SP flooding | 38.52 | 63.48 | 24.96 | 0.3 PV of emulsion followed by 0.35 PV of SP flooding | 39.14 | 64.47 | 25.33 |
