The potential for oil and gas exploration efficiency enhancement in consequence of the implementation of scientifically grounded theoretical concepts and new technologies of studying unconventional oil and gas facilities – impact structures is considered. A summary review is enounced regarding scientific investigations and manufacturing activities estimation of hydrocarbon prospects impact structures crystalline basement within the territory of Ukraine as well as in foreign countries. Nuanced analysis of data available brings us to the conclusion that direct-search soil vapor anomalies over oil and gas deposit areas are of diffusive nature. This has made it possible to turn to good advantage in estimating of unconventional facilities including impact structures. For illustrative purposes, cartographic results of Obolon’ impact structure investigation are represented. Also, analysis of Siljan impact structure satellite survey was carried out. As a result of which, several methodological principle for further studying oil and gas potential of Siljan impact structure were proposed. Industrial introduction of authors’ methodical technology may cause not only discovery of new commercial oil and gas deposit, but also carrying out task-oriented prospecting for presumable petroleum-bearing impact structures within the boundaries of Ukrainian shield, Dnieper-Donets Basin and other areas.
