MELBOURNE, Australia — 3D Energi has received approval from Australia’s regulator NOPSEMA for its Sauropod 3D seismic environmental plan.
This covers a 3,447-sq km area in the western half of the WA-527-P petroleum exploration permit in the Bedout sub-basin offshore Western Australia. Water depths range from 100 m to 150 m.
The permit is 195 km west of Broome on the Northwest Shelf, adjacent to the Santos-operated Dorado discovery and along trend from the recent 2022 Pavo oil discovery.
Acquisition and processing of ≥510 sq km of 3D seismic data over the most prospective areas are a minimum commitment for the permit’s primary term.
3D Energi will look to acquire the survey over a two-month period in 2024 or 2025. Sauropod MC3D will help evaluate prospectivity, especially delineation of potential Dorado lookalike traps identified on reprocessed 2D seismic within the permit.
Dorado’s trapping mechanism at Dorado involves erosional truncation of the Archer Formation sandstone reservoirs by large channels, which were subsequently backfilled with shales during a rapid rise in sea level. The company believes there could be a northern extension to the Dorado channel system into WA-527-P.
Among the main leads on the western side of the permit are Salamander, said to be the third largest undrilled structure in the basin. 3D Energi estimates 349 MMbbl of prospective resources across the Salamander, Whaleback and Jaubert leads.
The company is in talks with CGG on vessel availability for the survey and is also in farm-in discussions with various parties.
