Abstract: the article deals with the possibilities of the multielectrode measurement principle usage for the development of the electrical sounding technology on the base of the AMS-ZOND hardwaresoftware package. The main aim of new technology creation is the increasing of the field work efficiency for the geological section investigation in the depth interval approximately 200 meters, taking into account the specific peculiarities of the existent interpretation programs. The technique and technology of the group sounding method have been designed, also the possibilities of the applying of inversion array, based on the reciprocity principle, have been investigated with the purpose of the multichannel equipment usage. Measurements are conducted with the predetermined ratio “noise/signal”, which is controlled by the AMS-1 equipment, for the decrease of the enhanced noise level effect. The results of the experimental work show the productivity increase up to 4-5 times in comparison with the traditional vertical electrical sounding method with the adequate accuracy of obtained measurement results.

Key words: multielectrode soundings, electrical tomography, group soundings, reciprocity principle, inversion array.

Abstract. The peculiarities and intensity of the hydrocarbons manifestation in the field of the electrical parameters of the subsurface part of the section up to a depth of 60–80 m and also 200 and 600 m for the particular areas were investigated on the example of the survey of the number of oil deposits in Perm region for the solving of ecological and test oil search targets. The complex of complementary methods was formed to conduct oil prospecting in the conditions of urbanized territories (or with the help of the specially constructed generator for the fixed frequency setting). It includes the induction sounding method which is based on the usage of industrial (or specially generated) electromagnetic fields and provides the efficiency of the regional investigation conducting and getting of tentative information about the presence of the perspective oil areas; and the combination of conventional methods: electrical sounding, transient sounding, induced polarization method for the getting of the information about different electrical parameters of rocks in overlapping intervals of the effective depths which are controlled by each used method with the purpose of detailed verification investigations conducting on the oil perspective areas determined with the help of the regional survey. The test of the developed technology on the example of the Belskoe oil deposit has shown the accordance of the obtained results and the prior information about the spatial location of the increased oil content areas and the prospectively of it’s further development.

Abstract. Methods and technology of monitoring control of the geological medium physical condition on the territory of salt deposit for the purpose of possible failure phenomena prediction are considered. The technology is based on the usage of periodical territory investigations by the electrical sounding method in the complex with remote sensing observations on identified the most dangerous areas. The system of remote sensing monitoring observations is realized on the base of geometric sounding principle applying with the multichannel areal measurement of the generated electrical field, it allows to control the physical condition of rocks in different effective depth intervals with the constant position of electrodes. In this case the signal recording is out of the dangerous zone with the help of the system of line communication and the commutator of channel switching. On the practical example the information value of obtained results with advanced economical effectiveness and decreased risk of field survey conducting is shown. During the analysis of the spatio-temporal behavior of electrical resistivity it was identified that dynamic parameters are the most informative for determination of potential dangerous zones, in particular the velocity of resistivity change, which allows to estimate the availability of active geological processes on the investigated territory. The obtained data of monitoring measurements accord with the results of geodetic control and allow to get information about the behavior of stressedly-deformed condition of rocks, which is necessary for the prediction of the risk level of considered territory and possibility of discrete subsidence there.

Key words: monitoring, salt karst, electrical sounding, remote sensing observations, technology, failure phenomena, prediction.
