Discussed in the article are the results of testing of non-classical geoelectric methods of forming a short-pulsed electromagnetic fields (FSPEF) and vertical electric-resonance sounding (VERS), as well as technology of frequency-resonance processing of remote sensing (RS) data within a certain area of geothermal sources development. The experimental results show that the areas with geothermal sources can be operatively detected and mapped by areal survey of FSPEF method. The VERS sounding allows to define in the cross-section the bedding depths and thicknesses with thermal water horizons, as well as water-saturated reservoir. Field works of the searching character are executed by the FSPEF and VERS methods very quickly and easily. The technology of frequency-resonance processing and interpretation of remote sensing data can also be used for detecting and mapping areas of geothermal waters. The proven mobile geophysical methods make a significant contribution into emergence of a new paradigm of geophysical investigation in which the “direct” searching for a specific physical matter is realized: gas, oil, gas hydrates, water (thermal including), metallic minerals and rocks. The effectiveness of geophysical methods based on principles of this paradigm is much higher than traditional ones.

Keywords: geoelectric survey, electric-resonance sounding, anomaly of reservoir type, aquifer, hydrothermal source, water flow, well, water temperature.
