Correlation between Water-Oil-Ratio (WOR) and Water Oil Balance Ratio (WOBR):
{\rm WOR} = \Phi \left( \frac{ \Omega_W^{\downarrow} \cdot Q_W^{\downarrow} - \Omega_W^{\uparrow} \cdot Q_W^{\uparrow} } { EUOR - Q_O^{\uparrow} } \right) |
where is some function.
For example, one can select and search for the exponent , good water percentages , and even adjust in order to achieve the best model fit to the WOR history:
