Usually produced from water phase only

For volatile oil fluid model the water surface flowrate $\begin{array}{l}q_W\end{array}$ is related to water sandface flowrate $\begin{array}{l}q_w\end{array}$ as (see derivation):

(1)	$\begin{array}{l}\displaystyle q_W = \frac{q_w}{B_w}\end{array}$

where

$\begin{array}{l}B_w\end{array}$

formation volume factors between separator and sandface pressure/temperature conditions
