Some mechanisms are described whereby light hydrocarbon gases, mainly methane, migrate vertically from high-pressure structural and stratigraphic reservoirs to near-surface soils. When soil samples are subjected to differential thermal analysis, the carbon dioxide evolving therefrom is referred to as /DELTA/C, which usually appears in the form of a geochemical halo in the soil around the oil and gas fields. Three case histories are presented indicating the classic geochemical halo pattern overlying three different types of producing fields. 6 refs.
