Complex permittivity of crude oils and solutions of heavy crude oil fractions

ABSTRACT Dielectric spectroscopy is considered as an interesting method for determination quality parameters like density, viscosity and interfacial properties of petroleum fluids. In this paper are the mechanisms important for the dielectric properties of crude oils studied for development of new charaterising methods.
