Purpose. The paper presents research materials on well-known oil and gas fields in various regions with the aim of improving the methodology of satellite images and photo images frequency-resonance processing, assessing the prospects for oil and gas content of deep horizons of the cross-section in the areas and blocks of survey, demonstrating the efficiency and potential capabilities of direct-prospecting methods.

Design/methodology/approach. The developed mobile and low-cost technology includes modified methods of frequency-resonance processing and decoding of satellite images and photo images, vertical electric-resonance sounding (scanning) of a cross-section, as well as a method of integrated assessment of the prospects of oil and gas potential of large prospecting blocks and license areas. Separate methods of this direct-prospecting technology are based on the principles of the “substance” paradigm of geophysical research, the essence of which is to search for a specific substance – oil, gas, gas condensate, gold, zinc, etc.

Findings. Detailed studies on some fields showed that scanning with a large step of 1 m fixes the response intervals in the cross-section, within which it is advisable to search for productive layers. Separate layers can be selected in the cross-section when scanning with a step of 1 cm or less. The 1 cm cross-section scanning procedure can be used to locate missing low-thickness pay strata. In the Pripyat trough and in the DDD, the deep horizons of the cross-section are promising for the discovery of hydrocarbon deposits. Deep channels (volcanoes) filled with ultramafic rocks or granites were found at the deposits of Belarus, Ukraine, as well as in the Gulf of Mexico, through which the deposits in the upper part of the cross-section can be fed. At the SAX01 well in the Caspian Sea, the likelihood of commercial volumes of fluids inflows from the 7 km depth interval is very low. When conducting experiments on Ikaria Island the responses from hydrogen were recorded in separate intervals of the cross-section outside the basaltic rocks. At many survey sites, additional evidence has been obtained in favor of the possible synthesis of lonsdaleites in ultramafic volcanic complexes. Reconnaissance studies on the Lebanese offshore have shown once again that within fairly large prospecting blocks, commercial volumes of hydrocarbons may be absent. Deep channels (volcanoes) filled with sedimentary rocks of 1-6 groups were found on the surveyed blocks and local areas in different regions. Signals (responses) at the resonance frequencies of hydrocarbons are almost always recorded in the contours of such volcanoes. Within the channels (volcanoes) of deep migration of fluids, mineral matter and chemical elements, on which the responses from hydrocarbons were recorded, the presence of a boundary of 57 km was confirmed. Below this boundary, responses are recorded at the frequencies of hydrogen and carbon, above – at the frequencies of oil, condensate, gas and amber (only in channels of a certain type).

The practical significance and conclusions. The results of the conducted approbation of the developed direct-prospecting methods in various regions of the world testify to their efficiency, effectiveness and the possibility of practical application during the search and exploration of hydrocarbon deposits. The method of integral assessment of the prospects for oil and gas content of large blocks and local areas makes it possible to quickly identify unpromising prospecting objects and areas proposed for geological and geophysical study. The studies performed confirm the feasibility of additional work using direct-prospecting methods when choosing sites for well placement. A low-cost direct-prospecting technology of satellite images and photo images frequency-resonance processing is recommended for practical application in various regions of the world in order to preliminary assess the prospects for oil and gas potential of poorly studied and unexplored prospecting blocks and local areas. The practical application of direct exploration technologies will accelerate and optimize the exploration process for oil and gas.
