Abstract
Illustrative logging methods, systems, and software, provide for correction of cross-coupling error via a complex-plane extrapolation technique. Frequency-dependent measurements at each given borehole position will trace out a dependence of a quadrature signal component on the in-phase component. With linear or curve-fit extrapolation to the real axis, the cross-coupling error is readily compensated, enabling more accurate formation property logs to be derived over greater range of operating environments. The technique is particularly suitable for use with laterolog resistivity tools, where cross-coupling between current and voltage conductors might otherwise be problematic.
