Overview
Representing the most comprehensive palynological dataset currently available for the Triassic of the Bedout Sub-basin, this multi-client study enables the identification of over 50 correlative events through the key Early-Middle Triassic T. playfordii interval.
Enhanced Biostratigraphic Resolution
This multi-client study provides far greater resolution than the existing 3 zonal subdivisions available in all other open-file datasets.
Palaeoenvironmental Understanding
Refined palaeoenvironmental understanding of one of the North West Shelf’s most promising oil plays.
Extensive New Palynological Data
Quantitative palynological analysis of the Triassic of fifteen wells, incorporating more than 800 new and existing palynological samples.
Top Triassic Reinterpretation
Samples previously assigned to the Triassic are now considered to represent Triassic reworking into an Early Jurassic succession.
Background
The Bedout Sub-basin, located offshore Western Australia, has emerged as a significant focus for hydrocarbon exploration following notable discoveries in recent years. The 2018 discovery of the Dorado oil field marked the largest oil find on the North West Shelf in three decades, estimated to contain approximately 162 million barrels of light oil and condensate, along with significant gas resources.
Subsequent discoveries, such as the Pavo-1 well in 2022, have further demonstrated the region’s potential, revealing a net oil pay of 46 meters with excellent reservoir characteristics. These findings have positioned the Bedout Sub-basin as a promising area for future exploration and development.
However, it was quickly apparent that the palynology of the TR10 interval in the Bedout Sub-basin (and likely across the North West Shelf) needed a detailed review. Many of the biostratigraphic markers applied to this interval were inherited from eastern Australian palynological schemes and were often unreliable or of low confidence. Much of the data also related to quick look analyses and needed full quantitative re-study.

Deliverables
This multi-client study represents the most comprehensive palynological review of the TR10 play interval, with particular emphasis on the T. playfordii Zone. However, where present, all of the Triassic has been re-studied or new slides prepared.
Event Stratigraphy
New local high-resolution palynological event stratigraphy, with up to 29 subzones/events recognised across the T. playfordii Zone alone.
Consistent Data
One consistent palynological zonation scheme applied to all wells.
Digital Data
Fully quantitative, tabulated Triassic datasets with stratigraphic summary charts for each well.
Multi-well correlation panels
Multi-well correlation panels across the entire study area.
