Abstract In the inverse method of analysis, the model for the resistivity structure is deduced from the data. An iterative process is developed wherein the maximum residual between the measured data and the theoretically deduced values for a successively increasing number of layers is reduced to a value less than the scatter in the data. In carrying out this procedure the parameters for each successive layer are determined and the number of layers required in the interpretation is determined by both the spectral range of the data and the scatter.
