Table 4
Injection and production data of enriched gas flooding in the field Z and calculated EGRs.
| Injection stage | Enriched gas (LPG : NG, %) | Injection volume (rm3) | GOR | Produced gas (103 m3) | PFVF (10-3) | Production volume (rm3) | EGR (%) |
| Stage 1 | 59.8 : 40.2 | 145.8 | 883 | 19.35 | 4.26 | 82.48 | 56.57 | Stage 2 | 41 : 59 | 479.5 | 370 | 66.91 | 4.29 | 287.21 | 59.89 | Stage 3 | 37.1 : 62.9 | 556.9 | 950 | 71.38 | 5.68 | 405.06 | 72.73 |
