about FSPEF&VERS method

Hi everyone,I will  discuss some informations about usefulness considering  applicability concept of FSPEF and VERS via this blog.

Short Pulsed EM Field(FSPEF)& Vertical Electrical Resonance Sounding(VERS) methodology  establish 'extreme effective conclusions' on wide spectrum chapters to needs  of  geoenvironments on matters  as cost and fast !!!As an example,I share conclusions of a hydrogeologic application at Muş region(where,I must say that I realised considering Muş city information an 'image thrusting' comparing grid scale of Google Earth on grid scale of map!);

 

Chapter summaries the original express-technology of geoelectric investigation(so,the compact measuring equipment,methods of the undertaking the field measurements,algorithm and software for registrations,processing and interpretation of the geoelectric observations data).System allows effectively to solve the broad circle;

>ecological

>engineering-geological

>hydro-geological

>geological-geophysical problems 

In particular,technology was used for mapping zones of the oil contamination,for localisations of area with the raised moistening of soil,for studying the landslide processes and collapse,for finding and localisations man-caused drain from reservoir and underground water communication,etc.The technology was also used when undertaking the investigations for the water-bearing layers searching on Turkey and Ukraine territory!

Express-technology components and equipments are based on the study of the geoelectric medium parameter in pulsed unsteady EM fields,as well as the quasi-stationary electrical Earth field and its spectral characteristics over the investigated objects.It combines the method of formation of short-impulse EM field(FSPEF),flux-meter survey and vertical electric-resonance sounding(VERS).

 FSPEF technic is based on studying of the process of the short-impulse EM field formation in small-sized dipole ferrite antennas.The application in this modification of the method of short but high-power electric pulses gives us 'an opportunity to refuse the use of long lines and to reduce the energy consumption'.Moreover,small-sized dipole antennas and power supply let us 'reduce the observation period in the observation point',consequently,to raise the productivity and efficiency of the developed modification in comparison with the traditional ones.

NOTE.The flux-meter survey is caaried-out to measure the vertical component intensity of the Earth Electrical Field over the investigated objects.This information gives us an opportunity to get the thickness evaluation of the anomaly polarised layers in the anomaly zone.

Vertical electric-resonance sounding(VERS) is based on the research of the processes of natural medium polarisation and spectral characteristics of natural electric field over the investigated object.As far as the horizontally stratified cross-sections are concerned,this technology gives a possibility to efficiently divide the cross-sections on separate stratigraphic subsections in the sounding site and to determine its depth with high accuracy.Sounding effectiveness rises considerably if in the regions in view there are documented parametric boreholes which give the possibility to standardize sounding diagram to link separate meaning intervals with the corresponding stratigraphic layers.
