BKS module is designed for measurement of rock apparent resistivity. Existence of several variable-depth probes provides an estimate of rock nonhomogeneity in radial axis.

BKS module is designed for measurement of azimuthal dependence of rock apparent resistivity. Sectionalized central electrode A0 of scanning lateral logging allows to estimate rock azimuth in homogeneity along six directions by means of scanning. Scanning lateral logging is used for determination layer spatial arrangement.
