Abstract: In a form of the disclosure, electromagnetic propagation logging measurements are made for several magnetic moment directions of the electromagnetic energy, and can be examined and/or processed retrospectively in order to select the logging information which has a particular desired characteristic, such as the sharpest imaging of bed boundaries. By scanning the magnetic moment over a wide range of angles, one is assured of obtaining logging information that has a desired attribute, such as image sharpness. This can be determined by viewing a recorded log and/or by automatically processing the log data. Information from other ones of the several logs may be useful in optimizing other attributes, such as standoff immunity or signal-to-noise ratio.
