Underground water is used in many industrial and private ways and finding new sources of fresh water are important for people living on the Earth. Especially nowadays, when the ordinary water sources (lakes, rivers) are heavily polluted. Exploring for groundwater is similar to exploring for any other resource uses geological evidence along with geophysically-based measurements to help define perspective zones for exploitation. WE OFFER SERVICE: - geophysical investigation for underground water (more info here. Russian lang.) Proper well placement is key to obtaining good well yield, minimizing well interference, and water quality impacts. Impermeable igneous and metamorphic rocks may yield water in wells if the rocks are sufficiently fractured. Who We Serve: Rural homeowners Farmers/Ranchers/ Well drillers Community water systems Recreational property owners Developers 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. The system provides high-resolution geomechanical cross-section to depth of up to 5,000 feet. This technology protected by USA patent №6 199 016 B1 (you can read this patent, if you click here); - Transient electromagnetic method (TEM). This technology works so well in any geological settings, giving 97-98% 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 all of them 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. 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: BGF method can reveal faults and their intersections (nodes) so fast, which are the most appropriate places for water accumulation. 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 1 km! 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 stay.

3. 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.

4. 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.
UNDERGROUND WATER SURVEY

5. 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.
