Title: Geochemical Investigation of Australian and New Zealand Crude Oils: ABSTRACT

Author(s): R. P. Philp, T. D. Gilbert

Article Type: Meeting abstract


Australian and New Zealand oils are derived predominantly from terrestrial source material. Relatively sparse information exists in the geochemical literature on the distribution of biomarkers in terrestrially derived crude oils. A detailed geochemical investigation of oils from a number of basins in this region has revealed interesting and unusual distributions of biomarkers. The compound classes that were analyzed included sesquiterpenoids, diterpenoids, triterpenoids, and steranes. From the information obtained, it has been possible to correlate the oils from several basins, in particular the Gippsland, Surate, and Carnarvon, into a number of source-related families. Evidence was also obtained that indicated a contribution from coal-like source material for many of the New Zealand oils.
