The Woodside-Burmah Group had drilled 45 wells totaling 469,692 ft (143,155 m), in this remote offshore region to the end of 1973. Ten of the 37 wildcat wells discovered new fields, and all 8 appraisal wells were successful. Permit areas total 140,000 sq miles (360,000 sq km) and water depths are from 150 to 6,000 ft (46 to 1,830 m). Major tectonic elements include 3 essentially onshore Proterozoic crations separated by the Canning and Bonaparte Gulf sedimentary basins. The sedimentary basins cover both onshore and offshore areas. Other major depocenters--the Dampier and Beagle subbasins and the Browse Basin--lie entirely off shore from the crationic blocks. All 5 offshore basins are filled with thick Mesozoic to recent sediments. The basins probably formed as a result of continental rifting initiated during Permian time. Many of the basins are subdivided as a result of major block-faulting movements which occurred from Late Triassic to Middle Jurassic time.
