Session 3.3 ______ ___ GNGTS 2023 Figure 3: To test the applicability of the method a different layered system was proposed (blue line) from the data a polynomial expression was retrieved as described in the method section. Then, the polynomial expression was used to transform the data directly into a model in which the resistivity of the target layer is 50% higher compared to the original model. References Florio, G.
