List of top Geology and Geophysics Questions on Self-Potential (SP) method

Which one of the following geophysical methods is suitable for the identification of seepage of water from dams?

The given figure shows the self-potential anomaly observed over a two-dimensional thin sheet-type ore body whose strike is perpendicular to the plane of the paper. Which one of the following directions of polarization of the ore body leads to the given anomaly? \includegraphics[width=0.5\linewidth]{11.png}

Wenner DC resistivity survey. The operator forgot to cancel self-potential (SP) between potential electrodes before injecting current. With equal current magnitude: measured \(\Delta V_1=+158\ \text{mV}\) for current \(C1\rightarrow C2\) and \(\Delta V_2=-214\ \text{mV}\) for reversed current \(C2\rightarrow C1\). Determine the SP (in mV, integer) that existed between potential electrodes before current injection.
