Petroleum exploration carried out in the Perth Basin up to August 1975 has been reviewed to provide a current assessment of knowledge of the basin and to determine the need for future exploration. The Perth Basin is in the form of a half-graben which developed as a result of movement along the major Darling-Urella fault system which forms the eastern boundary of the basin. It contains very large thicknesses of post-Cambrian sediments known to include source, reservoir and cap rocks suitable for petroleum accumulation. The tectonic forces which have moulded the basin have been predominantly tensional and faulting is prevalent throughout the basin. A considerable amount of petroleum exploration has been done both onshore and offshore and some commercially exploited gas fields have been discovered onshore in the northern part of the basin. The prospectivity of the basin varies from area to area, but overall it is regarded as fair. There is considerable scope for future exploration, particularly offshore where the number of wells drilled is small considering the large area involved.
