WebeScholarship WebSep 1, 2007 · The chemical and isotope composition of natural gas varies depending on whether the gas is biogenic or thermogenic. Gas of thermogenic origin indicates that oil may be present whereas biogenic gas is unrelated to processes that form oil (Schoell, 1983). The determination of the origin of gas, whether biogenic or thermogenic, is …
WebIntermediate values may result from the oxidation of biogenic CH 4 or from gas which contains a mixture of biogenic and thermogenic CH 4. Oxidation of CH 4 can occur if gas migrates through an oxidizing environment such as the aerobic zone of the soil or a wetland.
