While CCS “looks like” a familiar oil and gas operation\, the rationale\, business case\, regulation and social license environment are very different. While these differences are crucial\, there are many less obvious but equally important technical differences in how CCS is implemented\, compared to the oil and gas paradigm. This course of seminars will explore what’s different about CCS. \nSite Selection and Characterisation – What’s Different About CCS? – Tess Dance (CSIRO) \nAbstract \n\nThe goal for carbon dioxide storage site selection and characterisation is to find a suitable location where an effective reservoir exists\, matched to a CO2 source in both volume and injection rate. To ensure the CO2 is safely contained\, the relative contribution of key trapping mechanisms need to be defined\, thus reducing adverse risks to natural resources or the community. In Australia\, the framework for offshore CO2 storage has been adapted from petroleum legislation. The tools\, processes\, and methodologies also mirror those developed in the search for oil and gas\, and one might think it’s simpler since factors like establishing there has been sufficient charge can be bypassed. Indeed\, to avert conflicts over resources\, locations where hydrocarbons are less likely to be found are preferred. However\, this preference leads to a quandary: how do we ascertain storage potential in areas lacking prior exploration data? Given this situation\, many assume that depleted fields are attractive options\, with minimal risk and uncertainty due to their history of retaining hydrocarbons and the extensive characterization by prior operators. But these sites bring their own unique set of challenges. In this first talk of the series we will introduce screening criteria required to find prospective CCS sites and some Australian examples where we show “what’s different about CCS”? \nSpeaker Biography \nDr Tess Dance has a PhD from the University of Adelaide in Petroleum Geoscience\, and over twenty years of experience in basin analysis and reservoir characterisation for geological storage of Carbon Dioxide. Dr Dance is the author of numerous high impact publications in the field of CO2 geological storage\, monitoring and verification\, and has specialised knowledge of sedimentology\, sequence stratigraphy and geological depositional environmental analysis. In her role as geo-modeller for the CO2CRC Otway Project\, she has been involved in well planning\, core logging\, data analysis\, seismic interpretation\, modelling\, and simulation for Australia’s first CCS demonstration pilot site. She currently leads the Reservoir Simulation team in CSIRO Energy Resources.

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. Strictly no walk-ins.

SUMMARY:2023 PESA WEBINAR SERIES: Machine Learning and Intelligent Augmentation Applied to Legacy Subsurface Data
DESCRIPTION:Kindly supported by Rock Flow dynamics  \n  \nThis live webinar will take place at: \n11am              – Perth \n12.30pm       – Darwin\, Adelaide \n1pm                – Brisbane\, Canberra\, Hobart\, Melbourne\, Sydney \n  \nUse the calendar link on this page to add this event in to your own calendar at the correct local time for your location. \nTickets are free for members (please log in to see this) and $10 for non members. \nPlease buy your tickets and immediately follow the link in the ticket e-mail (not the calendar invite or this webpage\, which is just generic and not event specific) to set up your registration with the webinar software well in advance of the time of the talk. Once registered with the webinar software you will receive a reminder e-mail 1 hour beforehand. \nMachine Learning and Intelligent Augmentation Applied to Legacy Subsurface Data \nPresented by Jess Kozman (Katalyst Data Management) \nAbstract \n\nRecent emphasis on low carbon energy projects in Australia  means large volumes of unstructured subsurface data become valuable to operators. . The need to  evaluate reservoirs for energy or carbon storage or light gas extraction means a requirement to de-risk geographic search and  make machine-readable text available for advanced data science algorithms. Companies with access to data gain a competitive advantage in licensing activities. Exisiting data management workflows may be too costly and resource intensive to support these emerging requirements. \nWe highlight how a  workflow using Machine Learning (ML) and Intelligence Augmentation (IA) can improve the efficiency of a typical data management workflow. Our example involves manually identifying relevant well logs in images from collection of tens of thousands of file types\, a typical task for an operator using open-file data in Australia. The current process may involve downloading from multiple state and federal repositories and manually entering indexing metadata into internal data repositories. \nWe have developed internal ML/AI data extraction workflows that that streamline automatically separating well log image files\, extracting mandatory indexing meta-data\, and presenting model-trained choices to end-users for adjustment and verification. The full solution involves image classification\, enhanced Optical Character Recognition(OCR)\, Natural Language Processing (NLP) for keyword labels and values\, and a User Interface (UI) that delivers and documents increased data quality and confidence metrics.

SUMMARY:PESA WA August Technical Lunch:  Flexible Solutions for both CCS Measurement\, Monitoring\, and Verification (MMV) and Offshore Windfarm Developments
DESCRIPTION:Hosted with thanks to our Platinum sponsor SLB \n  \n \nGold Sponsors Katalyst Data Management\, Applied Geoscience\, Delft Inversion\, DUG and IKON Science \n                \n                                                \n \nand Silver Sponsor Qeye \n \n  \nPESA WA invites you to our technical luncheon on Thursday 17th August\nFlexible Solutions for both CCS Measurement\, Monitoring\, and Verification (MMV) and Offshore Windfarm Developments \nPresented by Andrew Long (PGS) \nMeasurement\, Monitoring\, and Verification (MMV) are essential to Carbon Capture and Storage (CCS) projects\, ensuring their effectiveness\, safety\, and regulatory compliance. Precise CO2 emission measurements\, ongoing project performance monitoring\, and independent data verification provide stakeholder confidence in the CCS system’s greenhouse gas reduction\, safe operation\, and prompt issue resolution. \nLikewise\, developing ground models for offshore wind turbine placement demands a comprehensive approach that addresses various geotechnical\, geophysical\, regulatory\, and stakeholder aspects. \nA common element should be that any ‘baseline’ geophysical platform is built to best practice standards for both CCS and Wind projects. For CCS\, accurate subsurface characterization ensures reliable site candidate selection and ranking\, facilitating the deployment of appropriate monitoring technologies post-CO2 injection in a cost-effective manner. Similarly\, high-resolution 3D geophysical data for Wind projects enable the development of an accurate 3D ground model for integrating subsequent geotechnical and geophysical measurements\, reducing the need for costly new surveys when adjusting turbine foundation locations. \nThis talk comprises four stages: \n\nI present AI\, machine learning\, and automation solutions to enhance the petrophysical and geological understanding of near-surface and overburden areas crucial for both CCS containment and Wind projects.\nI outline an efficient workflow for CCS site screening\, focusing on Container and Containment elements.\nI briefly discuss methods for acquiring high-resolution (HR) and ultra-high-resolution (UHR) seismic data cost-effectively\, including suggestions for congested infrastructure areas where traditional seismic surveys are logistically challenging.\nI describe subsurface characterization (both CCS and Wind) and monitoring solutions (for CCS) that leverage innovations from stages 1 and 3.\n\n\nEvent Sponsors: \n \nTicket Prices: \nMember (Early Bird): $69.00 \nConcession Member [Retired\, Graduate or Hardship] (Early Bird): $59.00 \nStudent Member (Early Bird): $39.00 \nNon-Member: $99.00 \nMember (Non-Early Bird): $79.00 \nEarly bird pricing ends Thursday (1 week prior) at 5pm (AWST).

SUMMARY:PESA ACT/NSW August Technical Lunch
DESCRIPTION:Federal Government False Narrative About Cause of East Coast Gas Supply Shortage\, Gas Price Cap and Gas Reservation\nI have major concerns about the prevalence of misinformation spread by politicians\, leaders at the UN and the media. Evidence-based decision making has been replaced by emotional beliefs\, with politicians and senior bureaucrats spreading false information without being held accountable. The mainstream media prioritises sensational news over evidence-based reporting and avoids conducting in-depth research. The ABC and SBS\, two taxpayer-funded media outlets\, solely presenting one-sided and propagandistic reporting rather than a balanced\, evidence based narrative. \nThe reason for recent high natural gas prices and supply shortages in eastern Australia has falsely been blamed by Anthony Albanese and his Labor Government Ministers on the war in Ukraine. \nGas price increases began before the Russian invasion of Ukraine and the 2022 price spike was caused by local factors. The Federal Government then used the excuse that the gas shortage and higher prices were caused by the war in Ukraine to justify implementation of new legislation that enforced a gas price cap and domestic gas reservation. This presents as a socialist intervention. \nMisinformation is prevalent in politics\, the media and Government discussions about gas prices. Evidence-based facts are overlooked in favour of emotional narratives.\nThe increase in east coast gas prices can be attributed almost solely to a domestic gas supply shortage. That gas supply shortage has been caused by State Government energy policies.\nThe ACCC’s gas report reveals that domestic gas contract prices increased from late 2020 to mid-2021 and the supply outlook from 2022 onwards appears tight.\nThe 2022 Australian Energy Regulator “Gas Markets” report highlights a period of sustained high gas prices and tight supply in east coast gas markets. Factors such as depleting southern gas reserves\, overlapping electricity market dynamics and short-term spot exposure during the higher demand winter period contributed to the increase in gas demand and subsequently gas prices. \nThe blame for the gas supply shortage can be attributed to past and present State Governments in NSW\, Victoria\, SA\, and Queensland who have limited access to new petroleum exploration areas through regulations\, lack of expedited approvals and withholding vast areas prospective for gas exploration.\nThe absence of a coordinated national energy policy\, combined with subsidies for renewable energy projects has resulted in a shortage of reliable\, low-cost base load electricity which in turn has increased electricity prices and gas supply shortages. \nThe false narrative surrounding human-caused climate change has directly led to policies condemning fossil fuels and limiting onshore petroleum exploration. The finance sector’s withdrawal of funding for fossil fuel projects\, the abandonment of support by business groups and the lack of defence by petroleum exploration and production companies has also contributed to the situation. \nContrary to the narrative\, the Australian export LNG projects were not robbing gas from domestic supply. These projects were developed for the existing\, lucrative LNG export market in Asia\, where prices were higher and long-term contracts were more feasible. The small domestic east coast gas markets were adequately supplied by other domestic sources and the large gas reserves associated with LNG projects could not have been sold in Australia due to the small market size.\nThere is an urgent need for a coherent national energy policy incorporating a balanced approach to renewable energy and an orderly transition to ensure a reliable energy supply and mitigate the impact of rising gas and electricity prices.\nLegislative power for petroleum exploration and production in onshore areas\, including State-controlled waters\, is governed by each State and Territory under the Australian Constitution. \nThere has been significant depletion of existing onshore gas fields through production in South Australia\, Victoria\, and Queensland and also in the offshore gas fields Victorian\, South Australia and Tasmania. These gas fields are in many cases approaching the final stages of their production life and with the declining production rates comes increased production costs which is passed on to the consumer in the form of higher gas prices. \nThe lengthy and costly State Government regulatory processes\, community consultations and bureaucratic obstacles faced by petroleum exploration companies have all hindered the addition of a new gas supply. These processes often lead to delays and unnecessary costs which are ultimately either borne by exploration company shareholders or in the case of successful projects are funded by consumers through higher commodity prices. \nNew South Wales (NSW) petroleum exploration was effectively halted in 2011 initially in response to the Government responding to activists claims of the damage caused by the use of fracking. The NSW Government then conducted a review of petroleum exploration resulting in the cancellation of all existing petroleum exploration licenses except for those related to the Santos-controlled coal seam gas project in the Narrabri region. \nThe NSW Government referred to the cancelled licences as “zombie licences” claiming that they had all passed their expiry date or had not met their financial commitments. In fact\, the NSW Government had applied a compulsory moratorium on exploration in 2011 which prevented the titleholders from meeting their financial commitments by conducting exploration activities. \nApplication for development approval of the Narrabri Gas Project was first submitted in 2014 with conditional approval not granted until September\, 2020 – a 6 year process!!! In the meantime NSW has no domestic gas supply and is totally dependent on gas imports from South Australia\, Queensland and Victoria\, a rapidly dwindling gas resource. \nPetroleum exploration and development policies in Victoria\, South Australia\, and Queensland has effectively halted onshore gas exploration and the addition of a new gas supply. Moratoriums and bans on onshore gas exploration and development in Victoria as well as the competitive tendering processes for new exploration areas in South Australia and Queensland have either stopped or greatly reduced gas exploration in those states. The Queensland government has prioritised the release of new areas for coal seam gas and unconventional gas leading to limited opportunities for conventional gas exploration. \nThe demonization of fossil fuels by state governments along with the withdrawal of prospective exploration areas has resulted in a gas supply shortage and increased gas prices on the east coast. Additionally\, the replacement of fossil fuels with heavily subsidized renewable energy sources without a proper transition plan is seen as a contributing factor to the gas supply shortage\, high gas prices\, and electricity grid imbalances. \nThere are major concerns with the long-term impact on the average citizen\, businesses and productivity due to government policies and subsidies that favour renewable energy over fossil fuels.

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. Strictly no walk-ins.\n
