Abstract
For the evaluation of the petroleum prospects of a sedimentary basin, the following factors are generally considered. Lithology, mode of deposition, thickness of the sediments contained in the basin, source and reservoir rocks. Facies of the sediments, changes in facies and the trends of such facies changes. Relationship of the various formations to each other - conformity, disconformity, unconformity, regressive and transgressive overlap, erosional gaps and their significance structurally and for accumulation. Direct or indirect evidence for the presence of oil - seepages, traces or showings of bitumen, oil and/or gas existing bores, bituminous character of some of the stratigraphic members. Tectonics - folding (single phase, multiple phase), faulting, tectonic history and its bearing on migration and accumulation of oil. Types of tectonic traps, and stratigraphic traps in relation to folding and faulting (sandy facies near basement uplift, reef formation on crests of rising anticlines, sandy facies in connection with ancient fault lines). Some of these criteria can be applied to the North-West and the Fitzroy Basins, but it is realized that the information available is not complete enough yet to fully discuss all aspects involved. On the other hand it is felt that, at this stage, a brief review of the results already obtained can greatly assist in an outline of a future programme. It will be seen that much emphasis is laid on geophysical work i.e. gravity investigations for the regional aspect of the problem - the configuration of the basins - and seismic investigations of structures which are selected for deep testing. In our opinion the results obtained so far in the North-West Basin, by both types of geophysical work, have clearly demonstrated the soundness of this way of approach
