Update (February 2019): Data from the newly released Phoenix South 2 well has been added to this palynological study.
MGPalaeo has conducted a comprehensive palynological study that increases the biostratigraphic resolution and palaeoenvironmental understanding of the Triassic in the Bedout Sub-basin. Download the full PDF here.
The recent discoveries in the Dorado 1 and Phoenix South 3 wells represent the most significant new play on the Australian North West Shelf in recent time, and highlight the importance of this area for oil and gas exploration. Dorado 1 discovered light oil over a depth of 96m (net pay 79.6m) in highly porous (~20%) and permeable (100 to 1,000mD) rocks, whilst hydrocarbons were observed in Phoenix South 3 from 5173m to the lowest closing contour at around 5304m within the Caley Member (Carnarvon Petroleum Ltd, 2018).
Representing the most comprehensive palynological dataset currently available for the Triassic in this area, this study enables the identification of over 20 correlative events through the key Early-Middle Triassic T. playfordii interval. This provides far greater resolution than the existing 3 zonal subdivisions available in all other open-file datasets.
The analysis has resulted in revised palynostratigraphic interpretations for each of the eleven wells, and a new understanding of the ranges of key marker species.
