A system for generating an image of an Earth formation surrounding a boreho le penetrating the formation. Resistivity of the formation is measured using a DC measurement, conductivity and resistivity of the formations is measured with a time domain signal. Acoustic velocity of the formation is also measured. The DC resistivity measurement, the conductivity measurement made with a time domain electromagnetic signal, the resistivity measurement made with a time domain electromagnetic signal and the acoustic velocity measurement are combined to generate the image of an Earth formation. |
