A new 3D Petroleum System Model for the Exmouth Sub-basin, related data and interpretation is available from NOPIMS or ausgeodata@ga.gov.au. The data and models cover the area from the Exmouth SLB15 MC 3D MSS Seismic Survey (ENO0603273) and is built on interpretation of the entire Mesozoic succession and has included an improved understanding of fault timing and the complex resulting structure.
