SUMMARY:PESA SA/NT July Luncheon
DESCRIPTION:PESA SA/NT July Luncheon\nNew Geological Studies Leading to 2025 Acreage Release in the Polda and Otway Basins\, SA\nPaul Strong and Sharon Tiainen \n(Energy Resources\, Geological Survey of SA\, Department for Energy and Mining)\nThe Polda Basin is a 10\,000 km2 Neoproterozoic to Jurassic basin covering the central western portion of the Eyre Peninsula of South Australia and extends westwards into the Great Australian Bight. The basin is only lightly explored\, with the last significant hydrocarbon exploration occurring in the offshore Polda Basin in the late 1970s/early 1980s\, with no reported hydrocarbon shows except for a relatively minor gas show of 40 ppm methane in Mercury 1. However\, source rock studies in the Jurassic section indicate the presence of immature\, relatively high TOC and excellent generative potential for both oil and gas from carbonaceous claystone and coal. Recent work by the GSSA (Tiainen\, 2025) indicates the presence of a potential source rock from the underlying Neoproterozoic Kilroo Formation\, with oil staining identified in the permeable reservoir intervals in the Polda Formation in the onshore mineral drillhole Kilroo 1A. In addition\, recent work conducted at the University of Adelaide suggests that there may be potential for a natural hydrogen accumulation within the onshore Polda Basin (Rumi Daruso 2023\, shown in Margiono et al. 2024). \nFollowing a recent acreage relinquishment\, one new Regulated Substances Exploration Licence (RSEL) in the Polda Basin is being offered as acreage release block PO2025 RSEL-A by the South Australian Government for competitive work program bidding. \nThe Otway Basin is one of the best known and most actively explored of the series of Mesozoic rift basins that span the southern coastline of Australia\, formed following rifting between the Antarctic and Australian plates. Over the last 2 years DEM has conducted studies over most of the onshore Otway Basin in South Australia\, with results suggesting that significant hydrocarbons have been generated and expelled in a number of structural troughs in the region\, and that suitable reservoir fairways and new play types are now better defined than previously. \nFollowing a recent acreage relinquishment\, five new regulated substances exploration licences (RSELs)\, three gas storage exploration licences (GSELs) and one new geothermal exploration licence (GEL) in the Otway Basin are being offered by the South Australian Government based on work program bidding. A key motivation for the acreage release is the looming shortfall in energy supply in the southeast Australian market. The South Australian onshore Otway Basin is in a strategic location for natural gas exploration and gas storage. \n  \n  \n\nEvent Details:\nThursday 31st July 2025\nLuncheon: 12 pm for a 12:30 pm start\nPlace: Ayer’s House\, 288 North Tce\, Adelaide \nThe luncheon will consist of 2 courses and drinks \nBookings close 5 pm Monday\, 28th July 2025 \nAny late bookings will incur an additional $20 fee. Strictly no walk-ins.

SUMMARY:PESA SA/NT June Luncheon
DESCRIPTION:PESA SA/NT June Luncheon\nThe impact of triggered earthquakes of the Basel geothermal project 2006 on Engineered Geothermal Systems\nMarkus Häring (Consultant)\nThe triggered earthquake of M 3.4 with subsequent events of M >2 was a turning point in the perception of induced seismicity caused by intentional pressure changes in the subsurface. The events followed a massive hydraulic stimulation into granitic basement at 5 km depth below the city of Basel. \nThe geothermal project attracted worldwide attention\, not only because the seismicity was felt throughout the city\, but also because\, for the first time\, induced seismicity was recorded in detail by a scientifically supported monitoring system. \nSince then\, microseismic monitoring systems have been greatly improved and can now be used in all underground operations where pressure changes occur\, such as oil and gas production\, fraccing\, CCS and EGS. \n  \n  \n\nEvent Details:\nThursday 26th June 2025\nLuncheon: 12 pm for a 12:30 pm start\nPlace: Ayer’s House\, 288 North Tce\, Adelaide \nThe luncheon will consist of 2 courses and drinks \nBookings close 5 pm Monday\, 23rd June 2025 \nAny late bookings will incur an additional $20 fee. Strictly no walk-ins.

SUMMARY:PESA SA/NT May Luncheon
DESCRIPTION:PESA SA/NT May Luncheon\nProspectivity of the Daralingie Shelf area of the Warburton Basin\, SA\nTim Rady (Geomorph Energy) and Rob Kirk (Consultant)\nAbstract:\nTo further highlight the prospectivity of the Warburton Basin\, the South Australian Department for Energy and Mining (SADEM) has undertaken a whole of basin project integrating regional seismic interpretations (using the 2D Cube)\, previous geological understanding\, well and standardized core interpretations. The May 2025 PESA lunch will be the first public release of the main outcomes from this project. \nThe Cambrian eastern Warburton Basin underlies the bulk of the hydrocarbon-producing Permian Cooper Basin in South Australia. The Warburton\, like the Cooper Basin\, is hydrocarbon bearing with a significant catalogue of hydrocarbon shows recorded from a wide variety of lithologies and stratigraphic intervals. Therefore\, understanding the stratigraphic context of hydrocarbon occurrences is critical to unlocking this basin’s prospectivity. It is in this context that two integrated seismic-based interpretations were undertaken in this project and are the focus of PESA’s May 2025 lunch time lecture. \nThe initial seismic interpretation\, by R. Kirk\, looked at the whole eastern Warburton Basin with the results providing the stratigraphic and gross depositional environment (GDE) concepts that underpin the entire project. From this work a new stratigraphic sub-division of the Warburton Basin has been developed (Kirk et al 2025). Subsequently\, the second seismic study was undertaken (by T. Rady) building upon the seismic sequence stratigraphic framework developed by Kirk et al (2025) by combining seismic attributes\, structural and seismic facies mapping and core descriptions to develop GDE and updated reservoir distribution maps for the uppermost section\, termed ‘400-1000’. This work has provided new insights into the basin stratigraphy\, evolution and prospectivity for hydrocarbons (Rady et al 2025). \n  \n\nEvent Details:\nThursday 22nd May 2025\nThe May luncheon is a week earlier than usual due to the AEP conference during the last week of May \nLuncheon: 12 pm for a 12:30 pm start\nPlace: Ayer’s House\, 288 North Tce\, Adelaide \nThe luncheon will consist of 2 courses and drinks \nBookings close 5 pm Monday\, 19th May 2025 \nAny late bookings will incur an additional $20 fee.

SUMMARY:PESA SA/NT March Luncheon
DESCRIPTION:PESA SA/NT March Luncheon\nThe Perth Basin: Seven years of learnings\nAndrew Farley (Strike Energy)\n  \nAbstract:\nExploration in the Perth Basin commenced back in the 1960s\, but it was the discovery of the Kingia gas play by AWE Energy in 2014 that kicked off the latest round of exploration and development. The Waitsia gas discovery inspired Strike Energy to enter the basin in 2018 with success at West Erregulla 2 in 2019 proving that porosity and permeability continues to preserved despite greater depth. To date\, Strike has drilled 13 deep wells and acquired 6 new seismic surveys across the Permian Kingia and Jurassic Cadda/Cattamarra plays. This has led to the discovery of 4 new gas fields\, one of which is now on production\, and two which are being developed. \n  \n\nEvent Details:\nThursday 27th March 2025\nLuncheon: 12 pm for a 12:30 pm start\nPlace: Ayer’s House\, 288 North Tce\, Adelaide \nThe luncheon will consist of 2 courses and drinks \nBookings close 5 pm Monday\, 24th March 2025 \nAny late bookings will incur an additional $20 fee.

SUMMARY:PESA SA/NT February Luncheon
DESCRIPTION:PESA SA/NT February Luncheon\nSeismic interpretation of the Petrel Sub-basin CO2 Storage Opportunity \nJames Komenza\nAbstract: \nAn integrated geologic and geophysical study of the Mesozoic storage resource in the Petrel Sub-basin (Bonaparte Basin). This study includes regional petrophysics\, geomechanics\, rock physics\, seismic reprocessing and inversion in an area of sparse well and seismic data. \nAlthough numerous wells have been drilled in the Petrel Sub-basin\, their focus has been the underlying Palaeozoic petroleum system\, resulting in scant or compromised data quality in the overburden. This often limits data utility for reservoir characterization\, field appraisal and development planning for the primary Mesozoic storage targets. Seismic reprocessing and quantitative interpretation supported by a model-based rock physics workflow have been used to fill in some of the gaps. This new data has been used to interpret depositional trends of both reservoir and seal\, reservoir quality\, heterogeneity and clay content\, seal presence and thickness\, and interval velocity away from well control. Insights from this study further highlight the suitability of G-11-AP for large scale CO2 storage. \n  \n\nEvent Details:\nThursday 27ht February 2025\nLuncheon: 12 pm for a 12:30 pm start\nPlace: Ayer’s House\, 288 North Tce\, Adelaide \nThe luncheon will consist of 3 courses and a 3-hour drinks package \nBookings close 1 pm Monday\, 24th February 2025 \nAny late bookings will incur an additional $20 fee.

SUMMARY:PESA SA/NT Christmas luncheon
DESCRIPTION:PESA SA/NT Christmas luncheon\nAnnus Mirabilis\nThe breakthrough year when petroleum geoscience changed forever\nRhodri Johns\n  \nAbstract: \nIn a single remarkable year\, several key papers and books were published that revolutionised the petroleum geosciences. \nSome of these publications introduced groundbreaking ideas\, concepts\, and methodologies that stunned and astonished both academia and the petroleum industry. Others synthesised state of the art in disciplines such as sedimentology and geochemistry\, building on developments from the previous decades\, like pieces of a jigsaw puzzle falling into place; these works not only led to a more innovative approach to petroleum exploration but also laid the foundations for systematic basin analysis\, play analysis\, petroleum systems analysis\, and risk analysis – approaches that would emerge as essential tools for the petroleum industry in the 1980/90s and beyond. \nWhat were these pivotal publications\, and who were their authors? How and where did these ideas and breakthroughs originate\, and how were they received by both academia and the industry? \nRhodri Johns will tell this story from a personal perspective\, offering new insights from those closer to the action. \n  \n\nEvent Details:\nThursday 12 December 2024\nLuncheon: 12 pm for a 12:30 pm start\nPlace: Ayer’s House\, 288 North Tce\, Adelaide \nThe luncheon will consist of 3 courses and a 3-hour drinks package \nBookings close 1 pm Monday\, 9th December 2024 \nAny late bookings will incur an additional $20 fee.

SUMMARY:PESA SA/NT November Luncheon: Natural Hydrogen Exploration in South Australia: An Update
DESCRIPTION:Natural Hydrogen Exploration in South Australia: \nAn Update\nChris Cubitt \nGeological Survey of South Australia\, Department for Energy and Mining \nhttp://www.energymining.sa.gov.au/ \nchris.cubitt@sa.gov.au \n  \nAbstract: \nSouth Australia took the lead nationally in enabling exploration licences for natural hydrogen on 11 February 2021 when amendments to the?Petroleum and Geothermal Energy Regulations 2013?declared hydrogen\, hydrogen compounds and by-products from hydrogen production ?regulated substances?. Following on from this\, seven companies have lodged over 40 applications for PELs targeting natural hydrogen over the State?s basins and crystalline basement provinces. PEL 687 is the first licence in Australia targeting natural hydrogen and was granted to first movers Gold Hydrogen Pty Ltd in July 2021 over Yorke Peninsula and Kangaroo Island. The second licence (PEL 691) was granted to H2EX in June 2022 over eastern Eyre Peninsula. An update will be given with respect to current exploration activities in both active licences and with reference to the current understanding of natural hydrogen prospectivity across South Australia. \n\nEvent Details:\nThursday 28th November 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\, 25th November 2024 \nAny late bookings will incur an additional $20 fee.

SUMMARY:PESA SA/NT Branch October Luncheon
DESCRIPTION:An emerging new Petroleum System with world-class plays in the \nTorres Sub-Basin\, Offshore Papua New Guinea \nTim Rady1 and John Chambers2  \n1 Geomorph Energy \n2Larus Energy Limited \n\nABSTRACT\nThe Papuan Basin is the only basin with production in Papua New Guinea but is relatively unexplored for a typical Australian Continental Margin Mesozoic basin. It hosts the Kutubu Oil Field Developments and the PNG LNG project\, as well as several gas fields that are planned to be developed in the coming years\, but its southeastern extension\, the Torres Sub-Basin\, remains undrilled. Modern proprietary and regional multi-client seismic data in the offshore Torres Sub-Basin is now revealing an active Petroleum system with a generating Late Cretaceous Source rock and three main identified play types: \n\nMiocene deep-water clastics in a large submarine Miocene to Pliocene foldbelt\nPinch-out plays of Miocene to Pliocene age against a basement high\nPalaeogene carbonate build-ups on basement highs\n\nThis presentation will focus on the Miocene to Pliocene submarine foldbelt plays within the Larus Energy-operated PPL579 license area that was covered by the Nanamarope 3D broadband PSDM seismic survey (acquired in 2023 by Larus Energy and Searcher). The pinch-out play is within the recently awarded Larus Energy-operated PPL695 license in the foreland basin south of the foldbelt\, while TotalEnergies is proposing to test the Palaeogene carbonate play with the Mailu-1 well in 2025. \nThe Nanamarope 3D seismic provides high-resolution images of large-scale submarine fan complexes\, deposited during the Mid-Miocene\, linked to active tectonism and the formation of the proto–Owen Stanley Range. The images suggest significant reworking of these turbidite systems by bottom currents into likely high reservoir quality contourite deposits with a wide spectrum of features formed during synchronous and asynchronous interaction of turbidity flows and bottom current activity. It is observed that bottom currents provide a mechanism to redistribute coarser-grained material up-slope and beyond the limits of the traditional turbidite fairway. \nThe new 3D seismic has allowed Larus to complete detailed structural mapping\, update GDE interpretations\, identify evidence for hydrocarbon migration and integrate petroleum systems and seismic synthetic forward modelling to derisk the prospectivity. Larus Energy is planning on drilling the giant Nanamarope Prospect in 2025 which\, if successful\, will open a large new play fairway for exploration and development and provide a much-needed revenue source for the nation of Papua New Guinea \n\nEvent Details:\nThursday\, 24 October 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\, 21st October 2024 \nAny late bookings will incur an additional $20 fee.

SUMMARY:PESA SA/NT Branch September Luncheon- 26 September
DESCRIPTION:Salt Cavern storage potential of the Polda Basin\, South Australia\nGlenn Toogood\, entX\, and Tim Rady\, Geomorph Energy\n\nThe Polda Basin is a Neoproterozoic to Jurassic sedimentary basin\, extending from the Great Australian Bight to the central Eyre Peninsula\, South Australia. It has previously been explored for petroleum\, uranium\, coal\, groundwater\, base metals\, potash and diamonds. There has been renewed interest in the Polda Basin for its underground gas storage potential in salt caverns\, given that Mercury-1 encountered >1200m of massive halite within Neoproterozoic red beds in the central offshore basin.\nentX Limited were granted Gas Storage Exploration Licences (GSEL) 781 and 784 and have been actively studying the basin to assess the likelihood of the proven offshore salt extending onshore\, where it may be engineered into caverns for underground gas storage (UGS) sites. UGS can provide gigawatt-scale storage of H2 gas and significantly reduce the levelized cost of storage. Such an asset would provide key advantages to H2 project concepts\, including DRI green steel from magnetite\, green ammonia and biofuels.\nTo assess the prospectivity for salt onshore and correlate the stratigraphy across the basin\, entX have taken a multi-disciplinary approach\, reviewing all available data and literature and integrating seismic reprocessing\, ICP-MS/OES and XRF analysis\, visual core and cuttings interpretation\, core density measurements\, spectral scanning and gravity forward modelling. Following this work\, the onshore Polda Basin has emerged as highly prospective for both salt and natural hydrogen. This talk will summarise the technical work undertaken\, new insights about the stratigraphy and plans for future data acquisition.\n\nEvent Details:\nThursday\, 26 September 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\, 23rd September 2024 \nAny late bookings will incur an additional $20 fee. Strictly no walk-ins.

SUMMARY:PESA SA/NT Branch August Luncheon- Thursday 15
DESCRIPTION:2024 Birdsall-Dreiss Distinguished Lecturer\nDr. Ben Rostron\nProfessor Emeritus of Earth & Atmospheric Sciences at the University of Alberta\n\nAbstract:\nGeology and hydrogeology at AQUISTORE: Canada’s first CO2 storage project associated with a commercial-scale coal-fired power plant The Aquistore research project is part of SaskPower’s Boundary Dam Integrated Carbon Capture and Storage project in Estevan\, Saskatchewan\, Canada. Carbon dioxide is captured from the Boundary Dam coal-fired power generation station and transported via underground pipeline to both the Weyburn oil field for EOR\, and to a 3400 m deep injection well at Aquistore. Initial CO2 injection at Aquistore took place in April 2015\, and through August 2023 more than 500\,000 tonnes have been injected. Geology and hydrogeology have played a key role in the entire project using both pre-existing and newly-acquired data. Hydrogeological characterization efforts were divided into four parts: regional hydrogeological and hydrochemical mapping of the site; hydraulic characterization of the storage zone during drilling/testing of the 3400m deep injection and nearby 3400m deep observation well; installation of an extensive shallow groundwater monitoring network; and ongoing hydrogeological and hydrochemical monitoring of the shallow groundwater in the area. All of the geological and hydrogeological characterization results indicate strongly favourable conditions for geological storage at the site: there are no significant faults in the immediate area of the storage site; the regional sealing formation is continuous in the area; the reservoir is not adversely affected by knolls on the surface of the underlying Precambrian crystalline basement; and the shallow groundwater and soil gas horizons do not appear to be hydraulically connected to the deep injection horizons in the subsurface. These results were subsequently used for project planning\, risk assessment\, and permitting of the site; demonstrating the overall storage integrity; and for Measurement\, Monitoring\, and Verification of CO2 storage for regulatory and public assurance. This talk will highlight some of the geology and hydrogeology results from Aquistore and provide an update on a couple of the more interesting outcomes of the project thus far.\n\n  \nEvent Details:\nThursday\, 15 August 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\, 12th August 2024 \nAny late bookings will incur an additional $20 fee. Strictly no walk-ins.

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.
