Geophysical Inversion Method Applied to Resistivity Soundings.

Inversion of theoretical and actual resistivity curves was performed using a computer program in order to determine an earth model. Considering a model of a flat layered earth, the inversion method is applied to one theoretical curve and four real resistivity soundings in order to obtain resistivities and thickness of different layers. The theoretical model was used to test the inversion scheme. The purpose of the four electrical soundings was to determine geoelectrical conditions for water accumulations. Using the inversion procedure it was possible to interpret the data with a high degree of accuracy. The results show that the method works well since it was possible to calculate geoelectrical model that fits the apparent-resistivity-curves.
