Multiple frequency electric excitation method and identifying complex lithologies of subsurface formations

机译:多频电激发方法及地下岩层复杂岩性识别

摘要

A method of identifying complex lithologies of subsurface rock formations includes the excitation of at least a portion of the rock formation with a multi-frequency electric current. The voltage resulting in the rock is measured and the phase and amplitude of such voltage is determined for each of the included frequencies. The resistivities are determined for each of the frequencies and are plotted as a function of frequency. The complex lithology of the rock formation is characterized by such plot.
