Abstract
Geoscience Australia has undertaken a regional seismic mapping study that extends into the frontier deep-water region of the offshore Otway Basin. This work builds on seismic mapping and petroleum systems modelling published in the 2021 Otway Basin Regional Study. Seismic interpretation spans over 18 000 line-km of new and reprocessed data collected in the 2020 Otway Basin seismic program and over 40 000 line-km of legacy 2D seismic data. Fault mapping has resulted in refinement and reinterpretation of regional structural elements, particularly in the deep-water areas. Structure surfaces and isochron maps highlight Shipwreck (Turonian–Santonian) and Sherbrook (Campanian–Maastrichtian) supersequence depocentres across the deep-water part of the basin.

Purpose
The purpose of this product is to provide digital surface grids, isochron grids, and fault maps for the Offshore Otway Basin that industry and academic stakeholders can use and integrate in their own regional prospectivity studies in the area.

Series Information
Lineage
This data is the result of regional seismic interpretation on offshore 2D seismic datasets. Key Upper Cretaceous supersequences where interpreted on 2D seismic data and tied to wells in Petrel software. Surfaces were then exported as ascii files from Petrel, imported to Petrosys where isochrones were generated. Faults were extracted from Petrel as shape files. All surfaces and isochrons are available as XYZ asci files.
