Formula 6.16
Electric resistance to a radial current from a wellbore
Input(s)
h: Height of Reservoir (ft)
$r_{e}$: Drainage Radius $(\mathrm{ft})$
$r_{w}$: Wellbore Radius $(\mathrm{ft})$
$\sigma$: Electric Conductivity (ohm/ft)
Output(s)
$R_{e}$: Electric Resistivity (ohm)
Formula(s)
$$ R_{e}=\frac{\ln \left(\frac{r_{e}}{r_{w}}\right)}{2 * \pi * h * \sigma} $$
