About the companyLtd. «Geoliss» was founded in 1995 by

Nikolay Andreev, a renowned Russian

geophysicist. Andreev N. was a one of the pioneers in

Russia in the field of radiological investigation

(measurement and analysis of radon).

We have being offering service an underground water survey since 2003. Moreover, we have developed the best complex of geophysical methods (biogeophysical method (BGF), Resonance-acoustic profiling (RAP) and Transient electromagnetic method (TEM)) for ground water survey.

UNDERGROUND WATER SURVEY

WE  WORK WITH UNIQUE TECHNOLOGY WHICH CONSISTS OF:- Biogeophysical method (BGF);- Resonance-acoustic profiling (RAP). The RAP - a breakthrough geophysical method for imaging underground structuries. Based on a discovery of a certain in-ground acoustic phenomena, the ever-present natural and man-made vibrations can be used to get subsurface information. This technology protected by USA patent №6 199 016 B1;- Transient electromagnetic method (TEM).

This technology works so well in any geological settings, giving more 95% positive result in water-well drilling even in rocky regions and human settlement. Achievement of a great result, using conventional geophysical methods, is so difficult, sometimes impossible, task in these places.Why? Because only conventional geophysical methods are:very sensitive to different obstacles;they need big expense of labour and time, although precision of located points for water-well drilling is quite approximately.

Analysis of the hydrogeological model of underground water (see fig. below):

- In the flat part of the Russian Federation, some geologic units serve as aquifers over hundreds of square miles;- In rocky regions, the permeability of the rocks and sediments changes over short distances. As a result, most aquifers in rocky regions are local (subvertical). A particular rock layer may serve as an aquifer in one location but not in another.Since most groundwater in bedrock flows through fractures and openings, locating a well where rocks have a high density of fractures may result in a higher yield.

This unique technology is especially effective in water survey:

•In complicated geological settings of rocky regions;

•In human settlement under different anthropogenic obstacles.

Main elements of technology are the following:

1) BGF method can reveal faults and their intersections (nodes) so fast, which are the most appropriate

places for water accumulation;

2) A short profile of RAP goes perpendicularly to the fault strike on this local area. Thereafter, we obtain

geomechanical sections and analyzing them. Depth of study is about 2 km;

3) Best fractured zones we check by Transient electromagnetic method.

10-15 measurement instead of 100-1000 in traditional way of survey!

Depth of study is about 0.3 km! Note: exist the opportunity to increase the depth of study.

Eventually, we are sure where a drill machine should work!

So, this technology is very efficient and economical.

We guarantee to determine in the shortest time where operational wells should be deployed. Thus it

reduces total cost of work very much.
