Otway Basin Mapping Products
Extensive mapping was undertaken by PIRSA between 1992 and 1994 to provide explorers with a comprehensive view of the structure of the Otway Basin. Four key seismic horizons have been mapped from existing open file seismic sections and industry interpretations, and tied to the network of 50 wells in the basin. These horizons – Top Sherbrook Group (late Cretaceous), Top Eumeralla Formation (early Cretaceous), Top Crayfish Group (early Cretaceous) and Top Basement (early Palaeozoic) generally divide the basin into megasequence units. Horizon maps have been converted to depth and a range of isopach maps have been prepared.
Many of the maps from this mapping are included in the PIRSA publication Petroleum Geology of South Australia - Volume 1 - the Otway Basin.
An Example: Top Eumeralla Formation Depth Map
