Abstract:

The Northwest Shelf of Australia consists of four major basins and a series of subbasins whose sedimentary thicknesses probably exceed 30,000 ft (9,000 m). It extends 1,500 mi (2,400 km) in a northeast to southwest direction, and averages more than 200 mi (320 km) in width. Structurally, the entire Northwest Shelf is dominated by Early to Middle Jurassic rifting. Although the tensional tectonic style predominates, compressional features are present. Proven petroleum reservoirs of the Northwest Shelf are Permian, Triassic, Jurassic, and Cretaceous sandstones. Except for the Carnarvon basin, where well density is still low, the Northwest Shelf is essentially unexplored. All the basins have most of the elements required for the generation and accumulation of petroleum. Recen ly announced discoveries in widely divergent areas of the shelf have created renewed interest in this large, unexplored offshore area, and may stimulate the exploration activity necessary to make the Northwest Shelf a major petroleum province of the future.
