Release Areas W13-16, W13-17 and W13-18 are located in the Exmouth Sub-basin, with W13-16 and W13-17 also covering a portion of the Exmouth Plateau. Area W13-18 is in close proximity to numerous oil and gas fields including Vincent/Van Gogh, Pyrenees/Macedon and Coniston fields. Release Area W13-16 is located entirely within a marine reserve Multiple Use Zone (IUCN VI); for further information refer to Special Notices.

The Exmouth Sub-basin formed as a series of northeast–southwest trending, en-echelon structural depressions during the Pliensbachian to Oxfordian. Pre-rift sediments are of Permian and Early to Middle Triassic age, and are gas-prone. The Upper Jurassic Dingo Claystone is the main oil-prone source rock across the Exmouth Sub-basin. Proven reservoirs occur within the Barrow Group and Dupuy Sandstone, with the Muderong Shale acting as the regional seal. Play types include: fault block traps within the Mungaroo Formation and sealed by the Dingo Claystone, and stratigraphic plays within the Barrow Group. Infrastructure is in place for oil production with further development underway to bring the Macedon gas field into production.
