Clumped methane
WebApr 4, 2024 · Here we apply stable isotopes, including methane clumped isotope measurements, to thirteen natural gases from five (Skrugard Appraisal, Havis, Alta, Filicudi, and Svanefjell) reservoirs in the Loppa High area in the southwestern Barents Sea to estimate the origins of methane. We compare estimates of methane formation … WebFeb 15, 2016 · Because 13 C-D clumping in methane is the only measureable clumped-isotope system at the current time that involves hydrogen isotope exchange, it is perhaps too soon to decide whether the higher-order corrections are generally negligible for the calculation of H/D-involved clumped-isotope signatures.

WebDec 14, 2024 · Methane clumped-isotope compositions provide a new approach to understanding the formational conditions of methane from both biogenic and thermogenic sources. Under some conditions, these compositions can be used to reconstruct the formational temperatures of the gas, and this capability can be applied to common … WebMethane clumped isotopes are methane molecules that contain two or more rare isotopes. Methane (CH 4 ) contains two elements, carbon and hydrogen , each of which has two stable isotopes . For carbon, 98.9% are in the form of carbon-12 ( 12 C) and 1.1% are …
