Popis: On the example of carbon-bearing formations, the concentration of a complex of trace elements in them is estimated. Examples are given of the distribution of productive continuous reservoirs in the Ordos (China), AustinChok, Bakken (USA) basins, as well as in the Domanik deposits of the Volga-Ural oil and gas basin. The features of the formations, namely the large length of the productive intervals of the section introduced into development during horizontal drilling, as well as the high concentration of ore metals and other environmentally hazardous chemical elements both in the shale deposits themselves and in shale oil, require a new approach to the study of shale deposits in all stages of geological exploration.
