SUMMARY:GDE Mapping Leading to Play Analysis in the onshore Otway Basin (SA)
DESCRIPTION:GDE Mapping Leading to Play Analysis\nin the onshore Otway Basin (SA)\nChris Cubitt (speaker)  & Paul Strong \nGeological Survey of South Australia\, Department for Energy and Mining \nhttp://www.energymining.sa.gov.au/ \nchris.cubitt@sa.gov.au; paul.strong@sa.gov.au \nThe Otway Basin is a Mesozoic rift basin located in southeastern South Australia and southwestern Victoria\, as well as extending offshore as part of Australia’s Southern Margin. Over 100 petroleum wells have been drilled since the 1890s wells\, and in 1987 Katnook 1 discovered economic gas in the Penola Trough\, with subsequent drilling leading to further discoveries and construction of a processing plant. To date almost 450\,000 barrels oil and 86Bcf of gas have been produced from the basin. \nThe modern Katnook Gas Plant (currently mothballed) has improved the economic viability of small gas discoveries to fuel both local gas markets and electricity generation. The SA Otway Basin is strategically connected to local southeast and statewide natural gas customers by the SEA Gas and SESA pipelines. \nAs part of a larger petroleum systems modelling (PSM) project gross depositional environment (GDE) maps were developed using 7\,965km of interpreted 2D seismic\, interval-specific isopachs with well log motifs\, regional seismic facies analysis and depositional environment (DE) interpretations from 772m of conventional core (23 wells). This mapping interpreted varied depositional systems\, including anoxic\, extensive ice-influenced lacustrine\, lacustrine turbidite\, extensive fluvial/lacustrine\, fluvial/flood plain and growth fault-bound ribbon-like alluvial fan apron environments. GDE maps were produced for the following six key intervals: Casterton Formation\, Lower Sawpit Shale (McEachern)\, Sawpit Sandstone\, Upper Sawpit Shale\, Pretty Hill Sandstone and Laira Formation. \nThe petroleum systems modelling showed for the first time significant oil and gas generation and expulsion in the lightly explored Robe and Tantanoola Troughs\, as well as the Penola Trough. \nPlay analysis has recently been conducted by DEM for all 8 intervals using the GDE mapping and the PSM results\, with the intention of stimulating exploration for hydrocarbons in this region\, including determining areas for a potential acreage release in 2024. The results have been documented on the DEM Energy Resources website under the Geology and Prospectivity \nhttps://www.energymining.sa.gov.au/industry/energy-resources/geology-and-prospectivity/mesozoic-basins/otway-basin  \n  \nEvent Details:\nThursday\,  Thursday 30th May 2024\nLuncheon: 12 pm for a 12:30 pm start \nPlace: Ayer’s House\, 288 North Tce\, Adelaide \nIncludes a 2-course lunch and drinks \nBookings close 1 pm Monday\, 27th May 2024 \nAny late bookings will incur an additional $20 fee. Strictly no walk-ins.
