The Vulcan sub-basin is one of Australia’s most interesting petroleum basins. It’s oil-prone nature, long exploration history and modest water-depth lifts it high in any basin-screening exercise. However, conversations with seasoned Australian explorers on the challenges of exploring the Vulcan sub-basin tempers the enthusiasm of the uninitiated.
In this talk the impact of the Novar MC3D, a re-processing of ten legacy surveys across the Vulcan sub-basin, upon the petroleum potential of the sub-basin will be examined. The Novar MC3D was processed through an extensive de-ghosted, de-multiple, anisotropic pre-stack depth migrated sequence to provide a superior quality seamless 3D dataset. These data have significantly improved imaging of the deeper Jurassic & Triassic structural & stratigraphic objectives and allow a new evaluation of the petroleum potential of the basin.
With these data, a re-examination of the structural history of the basin and fault geometries has been undertaken leading to a rejuvenation of petroleum potential of plays associated with: a) The Paqualin salt diapir; b) The depositional geometry of Jurassic-age sands; and c) Amplitude responses in the pre-Jurassic section.
The new-play imaging capability afforded by the Novar MC3D permits an assertion that it is possible that the next few years will see the re-emergence of the Vulcan sub-basin and surroundings as a prominent hydrocarbon province in Australia.
