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)
\[
R_{e}=\frac{\ln \left(\frac{r_{e}}{r_{w}}\right)}{2 * \pi * h * \sigma}
\]
