Abstract
AbstractMatrix equations are derived to transform the resistivity sounding data obtained in one type of a four‐electrode array to the corresponding resistivity sounding data that would be obtained using a different four‐electrode array. These expressions are based primarily on recent work in which we have established a linear relation between the apparent resistivity and the kernel function by using a powerful exponential approximation for the kernel function. It is shown that the resistivity sounding data of two different four‐electrode arrays have a linear relation through an essentially non‐singular matrix operator and, as such, one is derivable from the other for a one‐dimensional model and it can also be extended to two‐dimensions.Some numerical examples considering synthetic data are presented which demonstrates the efficiency of the method in such transformations. Two published field examples are also considered for transformation giving a reliable interpretation.
