Purpose. The aim of the study is to apply mobile and direct-prospecting technology for operative assessment of oil and gas potential of a large area in the Kherson region and a detailed study within the local search area; to improve the methods of the prospecting and exploration.
Design/methodology/approach. Mobile technology includes the frequency-resonance method of remote sensing data processing and decoding and the ground-based geoelectric methods of forming a short-pulsed electromagnetic field (FSPEF) and vertical electric-resonance sounding (VERS). Some methods of technology can be used at various stages of prospecting operations: reconnaissance (assessment of petroleum potential of major search blocks); detailed (assess­ment of projected oil and gas resources within the individual anomalous zones detected at the reconnaissance stage of prospecting); field investigation (ground-based field studies with geoelectric methods FSPEF and VERS to clarify the projected oil and gas resources and to choose the optimal locations of prospecting and exploration wells laying).
Findings. At the stage of reconnaissance prospecting studies in the south of the Kherson region, nine anomalies of the “gas” type and two anomalies of the “gas + condensate” type were detected and mapped with the estimates of reservoir pressure values in the range of 7.0-28.0 MPa, as well as two anomalous zones of the «geothermal water» type with water temperatures of 60°C and 89 C. In the area of the previously discovered Tarasovskaya geoelectric anomaly of the “gas” type, we carried out the ground-based studies by geoelectric methods of FSPEF and VERS. The contours of the anomaly were refined by the FSPEF survey. By VERS sounding at 19 points in the contours of the anomaly, we identified anomalous polarized layers (APL) of the “gas” type, which are confined to certain lithologic-stratigraphic complexes of deposits and are associated with gas content.
Practical value/implications. The research results allow us to claim that the surveyed area is highly promising for prospecting and exploration of industrial gas deposits in the Lower Cretaceous, date-Lower Paleocene and Maikop deposits. Given that the search and exploration of industrial accumulations of hydrocarbons on onshore and the de­velopment of discovered resources is much less expensive than in offshore areas, the mapped anomalous zones deserve a detailed study both by direct-prospecting technologies and by traditional geophysical methods (primarily seismic). The technology of frequency-resonance processing of satellite images is expedient in reconnaissance investigation of poorly studied regions of Ukraine with the purpose of operative detection of local areas for a detailed study. Mobile geoelectric methods of FSPEF and VERS can be used for a detailed examination of prospective local areas in order to estimate the predicted oil and gas resources within their contours and to select sites for prospecting wells location.

Keywords: mobile technology, the anomaly type deposit, oil, gas, drill, field work, geoelectric methods, fault zone, satellite data, direct search, remote sensing data processing and analysis.
