Effective wellbore radius of a well in presence of uniform-flux fractures

Input(s)

$\mathrm{x}_{\mathrm{f}}$: Fracture Half Length $(\mathrm{ft})$

e: Logarithmic Constant $=2.718$ (dimensionless)

Output(s)

$\mathrm{r}_{\mathrm{w}}$: Effective Wellbore Radius ( $\mathrm{ft}$ )

Formula(s)

$$ \mathrm{r}_{\mathrm{w}}=\frac{\mathrm{x}_{\mathrm{f}}}{\mathrm{e}} $$
