Abstract

Induced polarization logging provides in situ Q//v and S//w interpretations of shaly sands. An experimental IP tool was developed which measures quadrature conductivity and phase shift, in addition to conventional SP and resistivity measurements. The IP tool that was developed is a modular four electrode array which can operate in both frequency- and time-domain. Current and voltage are sampled simultaneously downhole and digitally transmitted to the surface in order to avoid capacitive coupling in the logging cable. Non-polarizable Ag-AgCl voltage electrodes are used to eliminate electrode polarization.
