Page 1. Researches

The main sphere of our practical interests is the decision of complex engineering-geological and geo-ecological problems. The laboratory has experience of field researches of ecological, permafrost, archaeological, engineering and ecological objects (pollution with petroleum, waste deposits, study of low-amplitude tectonics on the surface over coal deposits, study of a subsurface at the side of profiles, including that under buildings, research the surrounding of pipelines and so on).

We have an experience of researches on shallow-water and deep-water rivers and ponds, so in walking variants and from different vessels.

On territories with complicated conditions of electrodes grounding it is possible to apply special technology of electrical sounding or profiling without galvanic contacts. This technology was developed by B.G.Sapognikov (St.Petersburg) and advanced in MSU. Non-contact resistivity prospecting can be used both in summer, and in winter seasons.

The scientists of the laboratory are developing algorithms and computer programs for decision of forward and inverse problems of resistivity method. The program's products IPI-1D, IPI-2D, IE2DL are widely known in Russia and are applied in many countries abroad. IPI-1D is a set of programs for processing and interpretation of VES data within the framework of horizontally layered models. IPI_2D is a set of programs for processing, visualization and interpretation of VES data along profiles, received with the Total Electrical Soundings technology (TES), developed in MSU.

The IPI_2D programs effectively work in 2D inhomogeneous media and in horizontally layered media, as their application allows to suppress distorting influence of nearsurface inhomogeneities (NSI or geological noise) and as a result to increase an interpretational accuracy.

IE2DL is the set of the programs for resistivity and IP data modeling in 2D inhomogeneous media. IE2DL programs are used for study of influence of typical inhomogeneities, to choice of an optimum technology of investigation, to develop interpretation technology in inhomogeneous media, etc.

Except programs already listed above, our specialists developed some programs for modeling, studying, visualization and interpretation of resistivity data in anisotropic media (anisotropic halfspace, horizontally layered media with anisotropic basement and vertical contact of two anisotropic media).

There are also modeling programs for the case of 3D inhomogeneities in the halfspace and in layered medium.

There are programs of modeling and interpretation of the electrical soundings data measured on aquatorium for the cases of floating, bottom and vertical arrays for sounding bottom layers.

We can model the distribution of electric current lines and potential isolines in 2D inhomogeneous media. This modeling help to imagine better an electrical field behavior in inhomogeneous media and select the optimal technology for such media study.

The investigations of a topographic effect of the earth-air boundary over inhomogeneous 2D media are also executed.

For the last years within the framework of scientific themes, developed in the laboratory six Ph.D. and one Sc.D. theses were successfully defended.

On any question, mentioned in the present message we can give the additional information. It was published in three monographs on resistivity method, in numerous scientific publications. There are also advertising information and the detailed instructions to the sets of computer programs, and many are both in Russian and English language.
