One of the proposed qualification of reservoir quality based on FZI is given by the Table 1.
Table1. One of the qualification schedules of reservoir quality.
FZI | Reservoir Quality |

FZI > 8.0 | Very Good |
3.5 < FZI ≤ 8.0 | Good |
1.0 < FZI ≤ 3.5 | Medium |
0.45 < FZI ≤ 1.0 | Poor |
FZI ≤ 0.45 | Very Poor |
