Abstract
The results of experimental studies on some shale gas production areas in the USA, Argentina, and England are presented. The investigations have been conducted with using the technology of integrated assessment of the oil and gas prospects of large blocks and local areas, which include methods of frequency-resonance processing of satellite images and vertical sounding (scanning) of a cross-section in order to determine the depths and thicknesses of predicted hydrocarbon accumulations and rock. The results of studies at local sites in Eagle Ford and Vaca Muerta shale basins indicate the presence of hydrocarbon accumulations at these basins in traditional reservoirs in the lower horizons of the cross-section. Within all the examined shale gas production areas, deep channels of migration of fluids, chemical elements and minerals, filled with 1–6 groups of sedimentary rocks, were found. The materials of the work performed can be considered as additional evidence in favor of the concept of deep (abiogenic) synthesis of hydrocarbons, including those located in shale formations. Of particular interest is the survey site in England, within which there is a significant number of local zones of visible hydrogen degassing. It is advisable to conduct additional studies on its territory with the aim of a more detailed study of these local zones.
