Abstract:
The recent oil, gas and condensate discoveries in the Bedout Sub-basin have triggered a change in thinking in this hitherto underexplored region. Recent drilling at Phoenix South-1 (2014), Roc-1 (2015) and Dorado-1 (2018) all found success within the Triassic Lower Keraudren Formation. These discoveries suggest new play concepts need to be developed that may have previously been overlooked or deemed non-prospective. Their success also suggests that, apart from the charge system, entrapment and sealing mechanisms are the key to exploration success. Dorado-1 is a classic example where vintage seismic data failed to reveal an entrapment and sealing mechanism, while the modern Bilby Non-Exclusive 2D seismic data clearly shows the trap geometry, as well as reservoir-seal content through geophysical quantitative interpretation (QI) techniques.
