[Retracted] Three-Dimensional Inversion of Borehole-Surface Resistivity Method Based on the Unstructured Finite Element

Figure 14

Inversion results of anomalous bodies under mountain topographical model. (a) The change in the relative RMS during the inversion process; (b) slice of resistivity 3D inversion result; (c) slice of resistivity inversion result at XOZ profile; (d) slice of resistivity inversion result at YOZ profile. The outline of the true model is indicated by the white rectangles.
