  • Finding oil content of the formation using dielectric spectroscopy
    Patent number: 9422810
    Abstract: The present disclosure relates to methods and apparatuses for evaluating fluid saturation in an earth formation using complex dielectric permittivity. The method may include estimating fluid saturation using an estimated rate of change at a frequency of an imaginary part of permittivity relative to a real part of permittivity. The method may include performing dielectric permittivity estimates using an electromagnetic tool in a borehole. The apparatus may include the electromagnetic tool and at least one processor configured to store information obtained by the electromagnetic tool in a memory. The at least one processor may also be configured to estimate the fluid saturation.
