Abstract

Apparatus and techniques are described, such as for obtaining information indicative of a formation resistivity, such as using information from a galvanic measurement apparatus. A resistive parameter related to a geologic formation is estimated through use of a model. An electrical excitation is coupled from a well tool in a borehole to the geologic formation. Induced voltages resulting from the excitation are received using monitor electrodes selected according to the specified excitation mode, including receiving magnitude and phase information corresponding to the induced voltages. The resistive parameter of the model is then determined using the magnitude and phase information of the received voltages, and using magnitude and phase information about the excitation.
