Parameters:
| Parameter | Description |
|---|---|

| Pb | Bubble point pressure, [psia]. |
| Pwf | Bottom-hole flowing pressure, [psia]. |
Used in Blueprints
Klins-Clark Modified Vogel IPR
Construct an IPR curve using the Klins-Clark (1993) modified Vogel equation. This correlation improves on the original Vogel method by introducing a pressure-dependent exponent d that accounts for the ratio of reservoir pressure to bubble point pressure.
