STUDY OF THE ELECTRICAL CONDUCTIVITY DISTRIBUTION IN THE CRYOLITHOZONE USING THE METHOD OF REFLECTED ELECTROMAGNETIC WAVES (MREW)

Presented data of the method of reflected electromagnetic waves (MREW), obtained during the complex geophysical studies on the territory of an oil and gas field in the permafrost zone to a depth of over 500 meters, allow estimating the distribution of the relative electrical conductivity. Using direct measurements of MREW, subsurface boundaries, contrasting in terms of electrophysical characteristics, were detected. The paper presents a comparison of the MREW data with the data of the near-field transient electromagnetic sounding (TEM). The theoretical basis of the integration of the MREW and TEM methods in the 1–100 MHz range is discussed.
