Adsorption-induced negative carbon isotope sequence in over-mature coal-type gas from the southwest Ordos Basin
Abstract The carbon isotope sequence of alkanes is a key indicator used to distinguish organic from inorganic gas. A negative carbon isotope sequence (i.e., δ 13C1 > δ 13C2 > δ 13C3 > δ 13C4) is a characteristic feature of inorganic gas. Some gas samples from the Qingyang gas field in the s...
