Abstract
In response to the recent growing interest of subsoil users in the oil and gas potential of the Mesozoic deposits of the Fergana Depression, this article examines in detail the patterns of change in the qualitative composition of oils (density, viscosity, sulfur, paraffin, resin, asphaltene, and gasoline content) and gases (methane homologues, carbon dioxide, nitrogen, hydrogen sulfide, and helium content) and their prospects. The article presents the results of a comparative analysis of the physicochemical characteristics of oils, condensates, and natural gases. Maps of changes in the physicochemical parameters of oils and gases in the Jurassic and Cretaceous deposits of the depression have been constructed. A forecast of the quality of oils, condensates, and gases in exploration areas is provided, along with a geochemical justification for further geological exploration within the study area.
