The article analyses the interaction of a powerful low-frequency signal with an anisotropic medium over hydrocarbon deposits. The behaviour of the real and phase components of the surface impedance of the medium above the deposit in the mode of dual-frequency signals is studied. The analysis of the components of the surface impedance of the medium over hydrocarbons for electromagnetic waves with right and left circular polarizations is carried out depending on the permittivity and frequency of the probing signals. The obtained research results can be used in exploration geophysics to identify the environment above the deposits by the size and nature of the material and phase components of the surface impedance of the surface layer above the hydrocarbons.

The article analyzes the interaction of two-frequency electromagnetic waves with anisotropic media over hydrocarbon accumulation. The behavior of the real component έ3 of the dielectric permittivity tensor is investigated. The choice of signal characteristics is based on the use of different electromagnetic wave emission sources with amplitude and frequency ratio coefficients in the modes of powerful low-frequency and high-frequency signals. The dielectric permittivity tensor component έ3 as a function of dielectric permittivity and frequency of sounding signals was analyzed. Sounding modes of anisotropic media over hydrocarbons are recommended to identify the medium over the deposits and increase the accuracy of determining the boundaries of hydrocarbon accumulation. The obtained results of the research can be used in prospecting geophysics.
