This Record presents a summary of an analysis of 21 offshore Otway Basin wells (Appendix 1) based on data provided in open file Well Completion Reports (WCRs) and Geoscience Australia online databases. Additional data and interpretations are drawn from the large body of published material on the basin. Analysis was inhibited in some cases by the quantity of data in WCRs, specifically the paucity of maps provided in the interpretive sections. Fortunately, most well analyses appear to have a determination of the reason/s for failure that is reasonably clear even without maps. The end product is primarily focused on individual well results, specifically success and failure analysis. To put the wells in a geological perspective, the introduction outlines briefly the regional geologic setting, distilling the ideas of many workers through the basin's exploration history. The final section presents a petroleum systems focused summary of the main findings of the work. From this, critical risks have been identified and areas of higher or additional potential have been indicated.
