The study compares electrical prospecting in anisotropic media by Schlumberger and classical (Lundberg) arrays. Schlumberger symmetric arrays with source electrodes positioned at an angle to a steeply bedded anisotropic layer provides more prominent bending of field lines over conductors than arrays with the bedding-parallel position of electrodes. The reason is in higher effective resistivity of anisotropic layers at field direction across their bedding.
