WebJul 1, 2014 · Thermogenic gases yield formation temperatures between 157° and 221°C, within the nominal gas window, and biogenic gases yield formation temperatures consistent with their comparatively lower-temperature formational environments (<50°C). In systems where gases have migrated and other proxies for gas-generation temperature yield … WebSome use the compositional ratio C1/C2+C3 as a measure of wetness. Biogenic gas is very dry (i.e. consists entirely of methane). In contrast, thermogenic gas can be dry, or can contain significant amounts of wet gas components. Methane stable carbon isotope analysis provides the only means to differentiate between biogenic and thermogenic dry gas.
