Biogenic and thermogenic
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. WebTwo types of natural gas occurrences are present in the Cook Inlet basin. The major reserves (1.8 × 10 11 m 3) occur in shallow (less than 2,300 m), nonassociated dry gas …
