The laboratory of shallow-depth electrical prospecting
of geophysical department at MSU Geological faculty
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
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 near-surface inhomogeneities (NSI
or geological noise) and as a result to increase considerably an
accuracy of interpretation.
IE2DL - the set of the programs for VES 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 and etc..
Except programs already listed above, our specialists
developed some programs for modeling, studying, visualization and interpretation of resistivity data in anisotropic media
(anisotropic half-space, two- and multi-layered media with
anisotropic bedrock and for vertical contact of two anisotropic
media). There are also modeling programs for the case of 3D
inhomogeneous media, for inhomogeneous 3D objects in the
half-space and in layered medium.
There are programs of modeling and interpretation of the
electrical soundings data measured on aquatorias for the cases of
floating, bottom and vertical arrays for bottom layers' sounding.
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.
The main sphere of our practical interests - is the decision
of complex engineering-geological and geoecological problems. The
laboratory has experience of field researches of ecological,
permafrost, archaeological, engineering and ecological objects
(pollution by petroleum, waste deposits, study of low-amplitude
tectonics on the surface over coal deposits, study of a subsurface
at the side of profiles of investigation, 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
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-grounding electrical prospecting can be used both in
summer, and in winter seasons.
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 advertizing information and the detailed instructions to
the sets of computer programs, both in Russian and English language. ==================================================================
