PETROLEUM RESOURCES OF OFFSHORE SOUTHEASTERN AUSTRALIA

Abstract

THE GIPPSLAND Basin is established as a prolific producer of oil and gas from a number of giant fields and other major discoveries are yet to be developed. Further discoveries can be expected in this petroliferous basin which has good future exploration potential. The Bass Basin has been disappointing as commercial discoveries have eluded the explorers. However source and reservoir rocks are present and the basin has future promise if the key to the nature of accumulations can be found. The Otway and Great Australian Bight Basins cover a vast area and include very thick potential source formations and good reservoir facies. Thick sedimentary sequences in the deep basin have been little explored and no significant shows encountered. The basins have potential but there are exploration difficulties to be overcome before full potential can be understood.
