... the distribution of underground electric fields and currents. Currently, there is a lack of quantitative modeling studies on the cementing effect, which is often ignored in the steel casing’s modeling. Therefore, we adopt the equivalent resistor network (RESnet) method to investigate the impact of cementing...

... in these settings by creating rewrite the secondary fields due to casings approximately as low resistivity channels and consequently obscuring the original signal from subsurface geology. Several numerical studies have shown the strong distortion of the electric field caused by the metal casings located close...
