Ratio of Water Replenishment ( WR ) to the remaining oil reserves (
OR):
{\rm WOBR} = \frac{\rm WR}{OR} = \frac{ Q_W^{\downarrow} - Q_W^{\uparrow} } { EUOR - Q_O^{\uparrow} } |
where
EUOR | Estimated Ultimate Oil Recovery |
Q_O^{\uparrow} | Cumulative oil production |
Q_W^{\uparrow} | Cumulative water production |
Q_W^{\downarrow} | Cumulative water injection |
