Roebuck Super-Tie™ 2D Reprocessing
Unlocking Hydrocarbon Potential in the Bedout Sub-Basin
The Roebuck Super-Tie™ 3D Reprocessing Network encompasses over 5,000 km of enhanced PSTM data in the Bedout Sub-basin and the Broome Platform offshore Western Australia. The key to unlocking the latent hydrocarbon potential of the Bedout Sub-basin was initially unveiled in 1980 with the Phoenix-1 well, demonstrating a gas column exceeding 700 meters within the Triassic Keraudren Formation. The recent oil discoveries along the Phoenix South-Dorado trend substantiate the existence of a thriving petroleum system, subsequently shifting the paradigm on the region’s prospectivity.
The significant potential lies not only in the Phoenix South area but also in the elevated areas surrounding the basin. Dorado-1 and Keraudren-1 results manifest high-quality reservoir capacity embedded within the Triassic sediments. The studies suggest a distinct possibility of oil migration towards the neighbouring Broome Platform, analogous to the Stag, Gwydion, and Cornea fields, further underscoring the untapped potential. In addition to the Roebuck Super-Tie™, Searcher also offers the Bilby 2D Seismic Survey and the Offshore Canning Prospectivity Study, all designed to deliver a fresh viewpoint on the offshore Canning area.
