Wellbore electric voltage generation
Input(s)
\(V_{e, w}\): Electric Voltage at Wellbore Radius (V)
\(\Delta V_{e}\): Voltage Drop Between Wellbore Radius and Drainage Radius (V)
\(\mathrm{r}\): Specific Location \((\mathrm{ft})\)
\(r_{e}\): Drainage Radius \((\mathrm{ft})\)
\(r_{w}\): Wellbore Radius \((\mathrm{ft})\)
Output(s)
V: Voltage (V)
Formula(s)
\[
V=V_{e, w}-\Delta V_{e} *\left[\frac{\ln \left(\frac{r}{r_{w}}\right)}{\ln \left(\frac{r_{e}}{r_{w}}\right)}\right]
\]
