Using neo-pentane to probe the source of gases in accumulations of the Browse and northern Perth basins

The origin of gases in Australia's Browse and Perth basins is deciphered using the molecular and isotopic compositions of individual C1-C5 hydrocarbons. As neo-pentane is strongly resistant to biodegradation and least influenced by thermal maturation (Boreham and Edwards, 2008), its carbon isotopic composition provides a powerful correlation tool for biodegraded and high maturity gases. Examples of how this tool has been applied to decipher the origin of gases in Australia's Browse and northern Perth basins are presented here.
