Abstract
A method for determining the frequency-dependent dielectric permittivity spectrum of a rock sample, comprising:—defining a series of electromagnetic measurement data comprising at least a first measurement at a frequency from which a substantially frequency-independent value of dielectric permittivity ∈∞, can be obtained; and at least second and third measurements at different frequencies from which values for frequency-dependent dielectric permittivity ∈rock (f) can be obtained; and—using the first, second and third measurements to determine the frequency-dependent spectrum of the sample.
