SUMMARY:PESA SA/NT Branch July Luncheon
DESCRIPTION:Exploration for radioactive waste repositories near urban areas\n\n\n\n\n\n\n\nMarkus Häring\nHäring Consulting \nAbtract\nSave long term storage of nuclear waste is required even in countries without nuclear power plants. Switzerland produces about one third of its power with nuclear energy. The volume of high- medium- and low-level radioactive waste of over sixty years of production is in the same order as toxic heavy metal waste from industry and consumption. Radioactive waste has a precisely determined half-life and can be stored and monitored in controlled containments. In contrast\, heavy metal waste is diffusely distributed\, is not inventoried\, and is of indefinite toxicity.\nNagra\, the Swiss cooperative for the disposal of radioactive waste has explored for a suitable location in various rock formations throughout Switzerland. After forty years of exploration\, a suitable site has been found that is not only geologically safe\, but also meets all political requirements.\nWhen it is possible to find a suitable site for nuclear waste in a country with nine million inhabitants that is smaller than the Eyre Peninsula and on top is located in a tectonically active region\, it should be feasible to find a safe storage location in South Australia. \n  \nEvent Details:\nThursday\, 25th July 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\, 22nd July 2024 \nAny late bookings will incur an additional $20 fee. Strictly no walk-ins.

SUMMARY:PESA S/NT Branch June Luncheon on 4 July 2024
DESCRIPTION:Analogues for Subsurface Characterization for the Energy Transition\nProf Simon C. Lang\nCentre for Energy Geoscience\nSchool of Earth Sciences\, University of Western Australia\nsimon.lang@uwa.edu.au\n  \nThe energy transition over the next few decades will provide challenges to all geoscientists who will need to extend the skills and lessons learned from fossil fuel exploration\, development and production to carbon sequestration and utilization (CCUS)\, conventional and H2 gas storage\, sediment-hosted copper\, uranium and lithium exploration\, and related hydrological and geotechnical issues.\nTypically high quality and abundant data is mostly available where existing fields occur (seismic\, wells\, dynamic data)\, but data will be sparser where we need to undertake new geological studies to support the energy transition. To infill the scale-gap between seismic and wells\, all the way down to core and pore-level\, we need to deploy appropriate analogues for the tectonic\, climatic and accommodation/sediment supply regimes.\nThis presentation will focus on depositional systems and their subsurface reservoirs/seals/baffles\, and how analogues from seismic\, well data\, producing fields\, outcrops and modern depositional systems can help constrain the uncertainties involved with subsurface geo-modelling\, that will still be needed to develop the new energy resources needed for the energy transition.\nGeology Matters!\n  \n  \nEvent Details:\nThursday\, 4th July 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\, 1st July 2024 \nAny late bookings will incur an additional $20 fee.

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.

SUMMARY:PESA SA/NT CHRISTMAS 2023 PESA LUNCHEON DECEMBER
DESCRIPTION:CHRISTMAS 2023 PESA LUNCHEON DECEMBER\nPresented by: Dave Grybowski\, Consultant\nAbstract – \nIf you missed David’s double-header luncheon talk of October last year comprising Cry Me A River and the world premiere of The Project – A Play About Not Working Together\, here’s your second shot at the Christmas Cracker. This December\, PESA SA/NT is paying David $1\,000\,000 to return with another blockbuster. Before dessert\, David will lead a joint discussion on The Books That Hooked Me – an investigation of the childhood books and collectables that turned his head toward geology. Luncheoneers will be invited to share their experience. How can we turn those young brains we babysit into earth scientists and engineers with great Christmas gifts? Specifically\, the challenge of making engineering remotely interesting to a kid compared to all the neat things geological.\nAfter dessert\, there will be a thrilling slideshow on The Role of Toilet Paper. The Chinese invented toilet paper in the 6th Century after discovering gunpowder was much too powerful and what to do with all those books after inventing printing eight centuries earlier? David will show a great variety of toilet paper dispensers with video of how well they don’t work. Naturally\, there will be a tie-up with Christmas at the end\, and remember\, paper beats rock\, any day. \n  \nEvent Details:\nThursday\, December 14th\, 2023\nLuncheon: 12 pm for a 12:30 pm start \nPlace: Ayer’s House\, 288 North Tce\, Adelaide \nIncludes a 3-course lunch and drinks \nTickets: \nStudent Members – $25 \nMembers – $50 \nNon-members – $100 \n  \nBookings close 1 pm Monday\, December 11th.\nAny late bookings will incur an additional $20 fee. Strictly no walk-ins.

SUMMARY:PESA SA/NT September Technical Luncheon  "Cretaceous depositional environment interpretation of offshore Otway Basin cores and wireline logs"
DESCRIPTION:Cretaceous depositional environment interpretation of offshore Otway Basin cores and wireline logs; application to the generation of basin-scale gross depositional environment maps\nPresented by: Chris Cubitt\nDeputy Director Geoscience & Exploration \nGeoscience and Exploration Branch | Energy Resources Division – DEM \nChris.Cubitt@sa.gov.au \n  \n  \nAbstract\n\nGas production from the Inner Otway Basin commenced in the early 2000s but the deep-water part of this basin remains an exploration frontier. Historically\, the understanding of plays in this region were largely model driven and therefore the ground-truthing of depositional environments (DE) and gross depositional environments (GDE) are critical. This aspect has been investigated for the Sherbrook Supersequence (SS) by the integration of legacy wireline and core data\, with regional 2D seismic facies mapping of new and reprocessed data from Geoscience Australia’s 2020 Otway Basin seismic program. Core observations were matched to wireline logs and seismic facies with resulting well based DE interpretations calibrated to seismic resolution Regional GDE intervals. Integration of well and seismic observations lead to the compilation of a basin-wide Regional GDE map for the Sherbrook SS. This GDE map indicates the distribution of Sherbrook SS play elements such as source rock\, seal and reservoir\, especially across the Deep Water Otway Basin where well data is sparse. \n\n\nEvent Details:\nThursday\,  September 28th\, 2023\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\, 25th August\nAny late bookings will incur an additional $20 fee.

SUMMARY:PESA SA/NT August Technical Luncheon  "Critical Minerals in SA – The road to net zero"
DESCRIPTION:Critical Minerals in SA – The road to net zero\nPresented by: Bronwyn A Camac (Geological Survey of South Australia)\n\n  \nAbstract \n\nFor about 150 years\, the use of petroleum products has driven world economies and is the greatest influence on quality-of-life improvement.\nBefore then\, we burned whatever we could find\, to keep us warm\, to fuel our emerging technologies\, and to cook our food. But most of these fuels could not keep up with population growth. Our forests were being pillaged\, our health declined due to coal pollution and our oceans stripped of whales.\nOur societies turned to the emerging new fuel – oil and its cleaner partner\, natural gas. We found its value more than just a fuel – we could make things from it – plastic\, clothes\, medicines\, fertilisers\, cosmetics\, and the list goes on and on. So\, dependent upon these products\, it becomes difficult to imagine that we can ever do without them.\nBut that time has come\, just as with wood\, coal and whales\, the market has outgrown us\, demanding cleaner fuels and products which has no effect on the earth and its climate.\nThis single most disruptive event of the last 150 years is being addressed in all countries to drive our economies toward net-zero carbon emission. To support net-zero targets\, the market is moving towards new technologies\, such as electric vehicles\, renewable technologies\, space technology\, telecommunication and defence. All of these technologies need critical minerals.\nThis is space where the mineral resource industry and the energy resource industry collide!\nCritical minerals are described by Geoscience Australia as “minerals that are essential to our modern technologies\, economies and national security\, and whose supply chains are vulnerable to disruption.”\nSouth Australia is well-endowed with many of the minerals and metals projected to be in short supply as this energy transition progresses. SA is rich in copper and currently holds 69% of Australia’s copper resource. It is a major producer of mineral sands\, with their associated rare earth elements and is rich in graphite. A state-wide study is currently underway to uncover SA’s full resource potential\, putting us at the forefront of the world’s energy transformation. \n\n\nEvent Details:\nThursday\,  August 24th\, 2023\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\, 21st August\nAny late bookings will incur an additional $20 fee.

SUMMARY:PESA SA/NT July Technical Luncheon
DESCRIPTION:A seismic source field trial in the Bass Strait: Testing the impact of several different source configurations on geophysical quality\, received sound\, and direct impact on scallops and lobsters\nPresented by: John Cocker (Beach Energy)\n\n  \nAbstract:\nBeach Energy acquired a seismic source technology field trial in Dec 2021 in the shallow waters (50-80m) of the Bass Strait. The trial consisted of eight source tests acquired along two 2D lines\, including: a full-size array (2480 cu.in.) with Sercel G-GUN II in a wide-tow triple source configuration\, eSourceTM (2098 & 1049 cu. in.)\, reduced size (300\, 700 & 1260 cu.in.)\, and Distributed Source tests including Shearwaters Apparition test (140 & 340 cu.in.). A test of a 70 cu.in. airgun was also recorded during a whale mitigation procedure. The aim of the field trial is to investigate whether any of these source options: \n1. Provide the required geophysical data quality \n2. Significantly alter the received anthropogenic sound levels (SPL and SEL) \n3. Changes the impacts on benthic invertebrates via analysis of scallop and lobster specimens placed on the seafloor \nThis combined data will then be used to determine if any of the alternative source options are suitable replacements for conventional full-sized arrays and if any provide a meaningful reduction to potential impact on marine organisms. \nThe study was performed in conjunction with the Institute for Marine & Antarctic Studies\, Fisheries Research & Development Corporation\, Curtin University\, and the Department of Natural Resources & Environment Tasmania. \nScallop and lobster specimens as a model species for crustaceans and molluscs were placed on the seabed below the full array (triple and single source)\, both eSource arrays and one control location. The specimens were assessed over 6 months for physical damage\, chronic effects and survival\, pH\, refractive index\, total and differential haemocyte cell counts\, DNA damage and biochemistry. Lobsters were also assessed for righting ability. The results will not be available until Q4 2023. Noise loggers were collocated with the specimens to measure received sound. \nThe data processing was completed by Shearwater. The results show that all options result in lower S/N raw shot gathers; but also\, that modern processing algorithms are able to compensate for most of this through noise attenuation\, deblending and designature. eSource (2098 and 1049 cu.in.) and the reduced source size options provide very similar final stack and migrated gather quality to the full array. Both apparition tests (140 & 340 cu.in.) were very similar in 2D stack quality but with slightly lower S/N below 4Hz and above 64Hz. The data quality of the other distributed source tests was better in the shallow but worse in the deep due to poor randomisation achieved. There are differences in gather quality that require further investigation. These results demonstrate that alternative sources and/or smaller volumes have the potential to meet survey objectives whilst reducing impact on marine life. \n  \nEvent Details:\nThursday\, July 27th\, 2023 \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 Tuesday\, 25th July\nAny late bookings will incur an additional $20 fee.

SUMMARY:PESA SA/NT June Technical Luncheon  "A new 3D structural model for the Porgera Region\, PNG Fold Belt: the integration of petroleum and minerals exploration methods"
DESCRIPTION:A new 3D structural model for the Porgera Region\, PNG Fold Belt: the integration of petroleum and minerals exploration methods.\nPresented by: Gareth T. Cooper\, Enigma Energy Services\nWork by: Gareth T. Cooper\, Kevin C. Hill\, Peter Essy\, Mark Haydon & Agnes Pokondepa\n  \nAbstract \n\nThe Porgera Region is a complex strike-slip pull-apart zone located in the central Highlands of PNG. The region sits on the northern margin of fold belt close to the boundary with the Mobile Belt. The region is ~70km NE of the Hides gas field and has been the subject of numerous regional studies by petroleum companies since the early 1970’s. Porgera hosts a gold mine which is one of the richest in the world and lies in a wide valley at an elevation of 2800m surrounded by mountains up to 4000m elevation. The intrusive underlying the Porgera ore-body was emplaced in the earliest Pliocene at the time of maximum compression during orogenesis. \nThe mine has been active for some 30+ years and has been the subject of multiple geological studies over that period. However nearly all studies to date have concentrated on local-scale mapping using methods commonly utilised in the minerals industry. In 2019-2020\, the mine operators\, PJV\, engaged a new study\, this time at a regional-scale and deliberately integrating methods commonly used in the petroleum sector. This included the integration of legacy petroleum data including palynology\, field dips and mapping\, as well as the acquisition of new data including new field transects\, palynology\, pyrolysis-Tmax and the incorporation of these data into thermal modelling and 3D structural modelling software (3D Move). \nThis new regional mapping of the area used high resolution LIDAR in association with field mapping\, analysis of gravity and magnetics data and drilling of 300-500m deep core-holes has allowed development of a detailed 3D structural model. The draft model was used to guide a regional drilling campaign in early 2023 as well as a follow-up sampling program for palynology and pyrolysis. The model also reveals much about previously unknown regional heating events in the Late Cretaceous-Palaeocene as well as the distribution of the Jurassic Om Beds and the Late Cretaceous Chim Formation\, both of which are thermally mature and may have the potential to host deep gas reservoirs. \nThis presentation discusses the methodologies used in the study and the unique integration of minerals and petroleum methods. The resultant model elucidates much about both the Pliocene emplacement of gold-bearing fluids in the area as well as the potential for deep Toro and Chim-aged gas reservoirs within deep structures. \n\n\nEvent Details:\nThursday\,  June 29th\, 2023\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\, 26th June\nAny late bookings will incur an additional $20 fee. Strictly no walk-ins.
