Relation between hydrocarbon ratios of Japanese natural gases

Abstract

All C₁-C₅ alkanes of natural gases from several gas deposits and gas signs in Japan were measured. Logalisms of ethane/propane, neopentane/isopentane and isobutane/neopentane ratios show correlations. These correlations can be explained as decompostion process of these hydrocarbons by OH radical. Further, it is presumed that decomposition process of the hydrocarbons is a major controlling factor for the hydrocarbon composition of natural gas samples used in this study.
