Abstract
A dielectric well logging system is provided to determine dielectric constant and resistivity in formations invaded by water to determine oil and water saturations of the formations. Plural transmitters are activated in a time division multiplex manner and sensed by receiver coils. The amplitude ratio and phase difference between the signals sensed by the receiver coils are then used to determine dielectric constant and resistivity which may then be used to determine invasion characteristics.
