Abstract
Comparison of the interpreted result of a resistivity sounding curve with the data of a well drilled in the neighborhood of the resistivity station is treated as an important problem of geothermal exploration's aftercare. As a result, it becomes clear that temperature log in the well is correlated with the resistivity step distribution, which is plotted by using the solution of the iterative least squares interpretation for the resistivity sounding curve. Some of the geoelectrical indications are discussed for the location of permeable levels, which correspond to geothermal reservoir, the variation point of temperature log, the correlation of formation with resistivity layers, and their interface depths from the surface.
