Reprocessed seismic over Bedout sub-basin supporting next-phase drilling campaign

The partners in the Bedout joint venture offshore Western Australia have completed work on the Bedout Mega Merge seismic reprocessing project.

According to Carnarvon Energy, the main goal was to improve subsurface imaging and exploration prospectivity definition across the Bedout sub-basin, which contains the as-yet undeveloped Dorado oil and gas discovery.

The program involved integrating 10 seismic surveys covering a total area of 15,240 sq km, delivering more than 80% seamless coverage of the joint venture’s (JV) acreage.

DUG Technology reprocessed and merged the data to achieve a unified, high-resolution dataset, with the results set to support selection of targets for the next planned exploration drilling campaign starting in third-quarter 2026. The JV is preparing a multi-well drilling environmental plan and will sound out drilling contractors on rig suitability and availability.

Carnarvon added that the dataset enhances definition of the Bedout prospective resource base and the associated geological risk profile, with greatly improved resolution and clarity and reduced noise and greater clarity, providing a more detailed and accurate picture of the subsurface.

This has led to identification of previously undetected structural features and stratigraphic trends.

Work has started on Phase II of the project, which involves applying quantitative interpretation and seismic inversion to refine subsurface predictions, notably in terms of rock lithology for reservoir and seal characterization, to assist high-grading of future drilling prospects.
