Western Australia: oil and gas potential. Part 2. The north west shelf - Exmouth plateau activity
Part 2 of Weaver Oil and Gas Corp.'s discussion of western Australia's hydrocarbon potential focuses on the general geology and potential of the north west shelf, the Exmouth plateau within the shelf, and the onshore Canning basin. Exploration efforts have identified three distinct hydrocarbon provinces in the shelf: (1) a seaward, predominantly gas and condensate province, illustrated by the major Triassic and Jurassic field discoveries made on the Rankin, Ashmore, and Sahul platforms, (2) a central oil-prone province, named after field discoveries (Barrow Island and others) made in the Cretaceous section on structures located in the depositional troughs of the subbasins, and (3) a landward, Paleozoic gas province, indicated by Permian field discoveries in the Bonapart Gulf basin. The Canning basin's principal objectives are the dolomitized Ordovician carbonates, Devonian and possibly Silurian reefs, and Carboniferous and Permian clastic sections. Potential traps are associated with horst blocks, tilted or antithetic fault blocks, simple anticlines, reefs, and salt Diapirs.
