Investigation of electrical properties with medium and heavy Brazilian crude oils by electrochemical impedance spectroscopy

[Display omitted] •Investigation of electrical conductivity and dielectric constant of two oils.•The conductivity and dielectric behavior are mainly controlled by polars content.•Viscosity of a cut/oil blend can be determined by dielectric constant measurements.•Viscosity of a W/O emulsion can be de...
