The qOW plotis based on the following correlation between oil production rate and water production rate:
| LaTeX Math Block |
|---|
| q_W = a \, \cdot q_O + b |
|
where
| LaTeX Math Block |
|---|
| a = J^{-1}_O \cdot ( J_{1W} + J_{2W}) |
| | LaTeX Math Block |
|---|
| b = J_{2W} \cdot (p^*_2 - p^*_1) |
|
where
