The technology includes the universal measurement equipment complex, strategy of conducting the field observations, algorithms and a program for the measurement data processing and interpretation. The received results indicate the possibility of its using for searching for and exploring petroleum and gas deposits.

The results of geological and geophysical and reconnaissance geoelectrical investigations in the areas perspective for oil and gas in the west part of the Odessa region are presented. The field observations data enable one to select several areas by extensive anomalies of the geoelectrical field, with which the middle-sized and large deposits of hydrocarbons can be related.

The results of experimental geoelectrical investigations at the Zasyadko coal mine in Donbas aimed at searching for and contouring the concourse areas of gas mixtures are presented. The data of field observations enable one to select several areas by extensive anomalies of the geoelectrical field, within which it is reasonable to bore degasation boreholes.

The results of geoelectric investigation on the perspective in view of the oil and gaz Ludin area, which is situated within Volyn-Podolsk plate, are given. It is shown that "oil-and-gas deposit" type anomalies are mapped clearly by geoelectric methods. It is recommended to conduct the geoelectric studies together with another geophysical investigation with the aim to determine places for the exploration bore holes pawning.

A method of electroresonance sounding is described. It is based on studying the processes of natural polarization of medium and spectral features of natural electric field over investigation objects. The method allows to define the location depths of the stratigraphic cross-section complexes and separate anomalous objects. The electric-resonance method efficiency is demonstrated by the results of its practical application at the ecological, engineering-geological and geological-geophysical problems solving.

The results of geological geophysical and reconnaissance geoelectrical investigations in the oil and gas perspective areas in the west ern part of the Kherson region are presented. The field observations data enable to select the geoelectrical field anomaly with which the hydrocarbons deposit can be bound.

The results of application of the technology for direct searching and contouring of hydrocarbon accumulations, basing on geoelectrical methods of investigations, on the oilfield Kenby in the West Kazakhstan are presented. The sidebars of anomalies of the "deposit" type are determined with this technology in the main horizons of lower Carbon, middle Jurassic, and Triassic. The geological and geoelectrical cuts are constructed through the chosen anomalous zones, in which the main intervals of depths of sharing the layers-anomalies of the "deposit" type are determined.

The results of collation of geoelectric investigation data on the Western Kazakhstan oilfield in view of seismic and boring data are given. It is shown that geoelectic "oil-and-gas deposit" type anomalies coincides in plan on 60 % and resemble more the stated sidebars of the oil-and-gas fields. It is recommended to conduct the reconnaissance geoelectric studies ahead of seismic work in view of the main direction determination for the hydrocarbons search.

The results of the mapping of mudslide areas by geoelectrical and seismoacoustic methods on a declivity of the Dnieper river are given. It is shown that the zones of mudslide processes are conditioned by technogenic water flows that are formed by the drains from underground water communications.

The results of the geological, geophysical, and reconnaissance geoelectrical investigations in the areas perspective for oil and gas in the west part of the Kherson region are presented. The data of field observations enable us to select the geoelectrical field anomaly, with which the deposit of hydrocarbons can be associated.

The results of collation of the geoelectric investigation data on the Kenby oilfield with the seismic and boring data are given. It is shown that geoelectic "oil-and-gas deposit"-type anomalies coincide in plan by 60 % and more with the stated sidebars of the oil-and-gas fields. It is recommended to conduct the reconnaissance geoelectric studies ahead of seismic work with the aim to determine the main directions for the searching for hydrocarbons.

During the seasonal works of the 9-th Ukrainian Antarctic Expedition the thickness of the ice cap situated near the Academic Vernadsky station on the Galindez Island was measured. This problem was solved by the vertical electric-resonance sounding method that is widely used in solving different ecological, geologic-geophysical and geologic-engineering problems. Results of these works were used to set up: a sketch-map and 3-D diagram of the ice cap thickness on Galindez Island; vertical sections of the glacier mass along five profiles; sketch-map and 3-D diagrams of the Galindez Island surface both with the ice cap and without it. Researches the carried out show that the vertical electric-resonance sounding method can be effectively used for the West Antarctica studying of the ice cap structure.
