Abstract
Dielectric spectra of water-containing rocks forming a mineral framework of the oil-saturated bed (clay minerals amount to <16%) were measured in the frequency range from 500 to 15 GHz and in the temperature range from 20 to 80?C. A physical model for computing spectra of the dielectric permittivity and effective conductivity of the studied rocks has been elaborated. Its input parameters are water content (salt solution) and temperature. The errors of the computed spectra relative to the measured ones are estimated.
