Prats effective well radius equation

It appears that the behavior of vertically fractured reservoirs can be interpreted in terms of simple radial-flow reservoirs of large wellbore.
— Prats, 1961
r_{w_{eff}}=r_w e^{-S}

where


S = ln \left ( \frac{r_w}{r_{w_{eff}}} \right ) = ln \left ( \frac{2 r_w}{X_f} \right )
