Overview
An integrated sedimentological and palynological core study that focuses on four wells with core over the reservoir intervals of the Late – Middle Triassic of the Bedout Sub-basin: Phoenix 1 (Solander and Barret members), Phoenix 2 (Barret Member), and Roc 2 (Caley Member) in the Bedout Sub-basin, and Bruce 1 (Barret Member) in the adjacent Beagle Sub-basin.
Updated Depositional Model
Combined sedimentology and palynology help refine the depositional environmental interpretations of four key wells.
Detailed Sedimentological Descriptions
A total of 119.38 m of core from Roc 2 and 54.45 m of core from Phoenix 1, Phoenix 2 and Bruce 1 were described.
New Palynological Data
31 palynological core samples from Roc 2 and fourteen new samples from Phoenix 1 and Phoenix 2.
Complimentary Study
This study builds upon MGPalaeo’s palynological review of the Triassic of the Bedout Sub-basin to refine our understanding of Triassic depositional environments.
Background
Located offshore Western Australia, the Bedout Sub-basin has become a key area of interest for hydrocarbon exploration following a series of major discoveries. The Dorado oil field, uncovered in 2018, stands as the largest oil find on the North West Shelf in over 30 years, with an estimated 162 million barrels of light oil and condensate, plus significant gas volumes.
More recently, the Pavo-1 discovery in 2022 confirmed the sub-basin’s strong potential, uncovering 46 meters of net oil pay with excellent reservoir quality. Collectively, these discoveries underscore the Bedout Sub-basin’s growing strategic importance for future energy development.
