    Przenikalność dielektryczna ośrodków porowatych - czynniki wpływające na jej zmienność
    (2010) Drożdżak, Ryszard; Twardowski, Kazimierz
    The basic regularities, followed by one of the basic electrical properties of porous media, i.e. electric (dielectric) permittivity, are discussed in the paper. The basic types of electric polarization of dielectrics and changes of its character, depending on the frequency of external electromagnetic field, are presented. Petrophysical models enabling indirect evaluation of relative electric permittivity, frequently called dielectric constant of porous rock media, are presented. It mainly depends on the qualitative and quantitative characteristic of the mineral skeleton (solid phase) of the rock and saturating porous fluids, in that waters having anomalously high dielectric constant.
