DescriptionFormation resistivity as measured by the phase shift of a high frequency electromagnetic wave (hundreds of KHz to several MHz, 1.1 GHz in the case of Schlumberger's EPT tool); these measurements are typically sharp (good vertical resolution) and have good dynamic range, but their depth of investigation is less than that of measurements based on attenuation.
