The development of a seamless onshore/offshore seismic stratigraphic model of the Canning Basin, Northwest Shelf, Australia
The Canning Basin in Western Australia is classified as a frontier basin with significant petroleum potential. The sediment package is up to 15km thick with ages ranging from Ordovician to Quaternary. The Fitzroy Trough of the onshore Canning Basin has been studied extensively and has produced commercial quantities of hydrocarbons from Palaeozoic reservoirs, however, its offshore equivalent, the Oobagooma Sub- Basin, remains poorly studied. The aim of this project is to develop an improved stratigraphic and structural model the Canning Basin with a focus on connecting the onshore stratigraphy of the Fitzroy Trough to the offshore Oobagooma Sub-Basin. This will be achieved by using a combination of over 5000km of offshore and onshore of 2D seismic data and 20 petroleum wells. This project has been aided significantly by the recent acquisition of 705km of coastal reflection seismic data by Geoscience Australia. This dataset has been crucial for linking the onshore and offshore stratigraphy and correlations between widely-spaced wells. Ultimately, this project aims to improve petroleum exploration outcomes in the offshore Canning Basin through an improved understanding of the regional stratigraphy and structures in both prospective sub-basins.
