Abstract
ABSTRACT
Resistivity measurements were carried out in a survey area in the south of Germany. This area is characterized by complicated subsurface geology. Schlumberger full‐arrays and their respective half‐arrays were recorded simultaneously. The results obtained by the one‐dimensional (1D) interpretation of the full‐array measurements were incorrect because of a resistivity discontinuity. This discontinuity, under a relatively thick overburden, could only be located by the half‐array soundings. Its exact location and the resistivity distribution in the subsurface were ascertained by comparing the sounding curves with 2D model curves, which are calculated by a finite‐difference method.
