Description
Summary:Based on the example of carbonaceous formations, the concentration of a complex of trace elements is estimated in them. Examples of the distribution of productive continuous reservoirs in the Ordos (China) and Austin Chalk and Bakken (United States) basins, as well as in Domanik deposits of the Volga–Ural Oil and Gas basin, are given. The features of the formations, namely, a large length of the productive intervals of the section that are introduced into the development during horizontal drilling, as well as a high concentration of ore metals and other environmentally hazardous chemical elements in both theshale deposits themselves and in shale oil, require a new approach to studying shale deposits at all stages of geological exploration.
