The Bonaparte Basin has been actively explored for more than 20 years, with oil production from several fields (Jabiru, Challis-Cassini, Laminaria-Corallina, Elang and the depleted Skua field) and proposed production from giant gas/condensate fields (Bayu-Undan, Sunrise-Loxton Shoals-Troubadour and Petrel-Tern). Despite this focused exploration and appraisal, to date geoscientists have had a relatively poor understanding of the region's petroleum systems. To improve this understanding, isotopic and biomarker analyses of numerous oils, condensates and gases have been undertaken to geochemically characterise the hydrocarbon families in the Bonaparte Basin, and to correlate them with likely source rocks. Preliminary results of this study shows that two Palaeozoic and seven Mesozoic oil families can be identified in the Bonaparte Basin. Details of the petroleum systems active in this basin were presented at the recent AAPG International Conference in Bali (October 15-18, 2000) by Dianne Edwards and John Kennard, and continue to be investigated by AGSO's North-north-west Regional Project.
