| Abstract: | The parallel-disk sample holder used to measure the conductivity and the dielectric permittivity of dissipative materials is analyzed in terms of quasistatic electromagnetic theory. It is shown that the commonly used static solution is not accurate enough to interpret data at high frequencies. Interpretation of the data is improved when higher-order correction terms are added to the zeroth-order static solution.This paper discusses the dielectric properties of reservoir rocks at the frequency range from 20 MHz to 50 MHz and a new experimental formula is proposed. |
