Y_W=\frac{q^{\uparrow}_W}{q^{\uparrow}_L} |
It relates to Water-Oil Ratio (WOR) as:

Y_W=\frac{1}{1+q^{\uparrow}_O/q^{\uparrow}_W}=\frac{{\rm WOR}}{1+{\rm WOR}} |
The simplest way to model the production watercut YW in a given well is the Watercut Fractional Flow @model:

{\rm Y_{Wm}} = \frac{1}{1 + \frac{M_{ro}}{M_{rw}} \cdot \frac{B_w}{B_o} } = \frac{1}{1 + \frac{k_{ro}}{k_{rw}} \cdot \frac{\mu_w }{\mu_o } \cdot \frac{B_w}{B_o}} |

The most popular short-term production watercut models are given by the brute-force correlation with the flowartes Watercut Correlation @model.
