Cross-phase average formation pressure:
p_e = \frac{1}{N_\alpha} \sum_\alpha p_{e, \alpha} |
where
formation pressure of -phase | |
number of fluid phases |
In case of the most popular 3-phase Oil + Gas + Water fluid model:
p_e = \frac{1}{3} \left( p_{eo} + p_{eg} + p_{ew} \right) |
where
formation pressure of gas phase | |
