Product description:AbstractThis report examines the petroleum geology of three offshore areas which were jointly released by the Commonwealth of Australia and the State of Victoria in April 2007. The blocks are named V07-1, V07-2 and V07-3 and are all located in the north-eastern offshore Gippsland Basin, approximately 200 km from significant population and industry centres in the east Gippsland region. There is sizable petroleum infrastructure onshore from the blocks, including the plants at Longford, Lang Lang and Orbost, which process the produced petroleum from offshore fields. These areas are close to three major pipeline networks which distribute the processed gas to the Victorian, New South Wales and Tasmanian markets. Areas V07-1 and V07-3 are geologically more diverse than Area V07-2, within which only the Latrobe pinch-out play fairway is likely to be viable. Area V07-1 is attractive because it contains both the pinch-out fairway and also the top-Latrobe fairway within which the Sole and Patricia-Baleen gas discoveries occur. Access to a mature and generative Strzelecki source is guaranteed in the south-western part of the block; there reservoir and sealing components are also not seen as posing significant risks. However, the more northerly parts of V07-1 lie on the Northern Platform, where uncertainties associated with the top seal quality and hydrocarbon migration processes may be important. Area V07-3 is geologically the most diverse (four play fairways have been identified) block and would also be the most attractive, providing that the Golden Beach and intra-Latrobe fairways are located in areas of shallow water depth. Access to mature source rock is possible from several grabens within V07-3, though the nature of reservoir and sealing units is poorly defined. A significant amount of new seismic data is required in order to adequately assess the hydrocarbon potential of these new blocks within the north-eastern part of the Gippsland Basin. These new seismic data, when combined with an improved understanding of the hydrocarbon generation-migration and sealing processes in the areas, should provide the keys to unlocking the untapped potential of these frontier areas.
