Understand the Broader Picture | Westralia Access and WestraliaSPAN

A new collaboration between PGS and ION has added the WestraliaSPAN survey to the Westralia Access regional study, providing over 25 000 km of data that is engineered for basin-scale evaluation. Nearly all of the W20 blocks are covered directly by the Westralia Access and WestraliaSPAN surveys.

The regional study maps key horizons and ties wells across the entire shelf from the Northern Carnarvon basin through to the Bonaparte basin and provides commentary on the play types and key sequences expected in each basin.

  • Coverage across most of the NWS 2020 release blocks
  • Comprehensive basin analysis to save time and cost
  • Seismic data designed for seeing the bigger picture

Well data has been integral to the study, guiding the PSDM velocity model building and driving the reservoir characterization workflows. With a full suite of Prospect Scanner AVO volumes, gravity and magnetics report, and collaboration with local experts, this is one of the most comprehensive studies of the North West Shelf to date. Nearly all of the W20 blocks are covered directly by the Westralia Access and Westralia SPAN surveys.

Spanning from North Carnarvon, through Offshore Canning, Roebuck, Browse and Bonaparte, Westralia Access is one of the most comprehensive studies of the North West Shelf to date.

The PGS Westralia Access study offers coverage from North Carnarvon, through Offshore Canning, Roebuck, Browse, all the way to Bonaparte.
