Release Area W13-10 is located in the Beagle and Dampier Sub-basins, in the vicinity of the Bounty, Finucane, Fletcher and Mutineer/Pitcairn oil fields. Release Area W13-11 is located in the Dampier Sub-basin, in the vicinity of the Legendre and Sage oil fields. Release Area W13-12 is located in the Dampier Sub-basin, in the vicinity of the Corvus gas field. Release Area W13-13 is located in the Dampier and Barrow Sub-basins, in the vicinity of the Corvus and Campbell gas fields, and numerous oil fields including Chamois, Oryx and Tusk. Release Area W13-13 is located mostly within a marine reserve Multiple Use Zone (IUCN VI); for further information refer to Special Notices.
The Dampier, Beagle and Barrow Sub-basins contain Paleozoic to Cenozoic sedimentary successions, with maximum thicknesses of 10–20 km. The region offers proven petroleum systems of Late Triassic, Middle-Late Jurassic and Lower Cretaceous age. Both oil and gas accumulations exist within these Sub-basins, which offer a range of play types to be targeted. Gas is sourced from Triassic to Middle Jurassic fluvio-deltaic rocks of the Mungaroo and Brigadier formations, Murat Siltstone, and Athol and Legendre formations. Oil is sourced from the Upper Jurassic Dingo Claystone. Structural plays include tilted fault blocks and rollovers, anticlines and drapes, and horsts. Stratigraphic plays include pinch-outs, unconformity traps and transgressive sandstone packages at the base of the Locker Shale. The region contains existing infrastructure that will facilitate further development.
