For a direct current resistivity (DCR) survey, currents are injected to the earth, and flow. Depending upon the conductivity contrast current flow in the earth will be distorted, and these changes can be measurable on the sufurface electrodes. Here, we focus on a bloc target embedded in a halfspace below a highly conductive surface layer, and investigate what are happening in the earth when static currents are injected. The conductive layer will also impact the illumination of the target (conductor or resistor). By investigating changes in currents, electric fields, potential, and charges upon different geometry, Tx and Rx location, we understand geometric effects of the conductive layer for DCR survey.
