Why We Lose Women From Geosciences – Evidence-Based Causes and Solutions
Presented by Erin Martin (IGO / Women in Earth And Environmental Sciences in Australasia)
Abstract

Diversity and inclusion in the workplace optimise performance through the input of a range of perspectives and approaches that drive innovation. However, gender inequity is prevalent in STEM, and women remain underrepresented in geosciences.
In tertiary geoscience education globally, there is an approximately even gender split that persists into research degrees. However, the number of women begins to decrease from workforce entry, becoming progressively worse at higher levels. In academia, this presents as the “leaky pipeline” where the gender split at postdoctoral levels (often short-term fixed contract) is relatively even and there is a sharp decline in women entering continuing (tenured) positions and going on to senior (Professor) levels. In the minerals industry, the most male-dominated industry in Australia comprising only 17% women, most women are in non-geoscience roles. In mining, there is a strong divergence in the proportion of men and women at increasingly senior levels, with 92% of CEO positions held by men.
Research into the causes of the Leaky Pipeline reveals that there are numerous contributing factors including unconscious bias against women, lack of role models, workplace arrangements that don’t suit mothers, barriers to awards and jobs, unequal access to parental leave, bad experiences during fieldwork and sexual assault and harassment.
The elimination of sexual assault and harassment through the pervasive implementation of recommendations handed down from Parliamentary inquiries and institutional and corporate investigations is essential for creating a safe space for women in Geoscience. Communication and implementation of best-practice, evidence-based approaches, and solutions to the many other factors contributing to the loss of women from geoscience will be valuable in creating positive change. Improved efforts to understand and address the reasons why women leave geoscience careers will help to repair the “leaky pipeline”.

PESA ACT/NSW June Technical Lunch
2023-06-13 12:00 - 14:30 (Australia/Sydney) | Castlereagh Boutique Hotel, 169 Castlereagh St, Sydney, NSW, 2000, Australia
THE FEDERAL BUDGET 10 MAY 2023, ITS CONTENTS AND ITS IMPLICATIONS FOR THE ENERGY INDUSTRY
The Federal Budget is far from what is contained in the Treasurers Speech, the associated Ministers Press releases, the Budget documents themselves and the massive rhetoric that will flow from days after the actual speech in the House. There will be countless hours spent in preparing treatises and marketing documents from the many who feed off the circus and the media who have a vested interested in selling whatever.
The reality becomes a lot clearer when those with patience and tenacity actually spend time post delivery of the package of above by delving far deeper and working through both what is included in those documents and just as importantly what is NOT included.
This presentation given many days post the circus will address as many issues as become apparent with as much depth as is possible in a 30 minute talk, both being advanced and provided in common language avoiding jargon.
The more publicised issues are going to include the changes to the Petroleum Resource Rent Tax rules and funding for hydrogen and renewable energy sources, but that means there will be hidden stories for nuclear energy, major infrastructure support, graphite production and research into alternatives to lithium-ion batteries. The deliberate intention will be to make this session hum with ideas, identified issues and positive thoughts of how Australia can “move forward”, while keeping cost increases down for the masses.
Notice: previous event on PNG Darai Limestone by Tony Allan cancelled, apologies for any inconvenience caused.

PESA WA invites you to our technical luncheon on Thursday 15th June

“Monitoring reservoir pressure and saturation changes using extended elastic impedence from time lapse seismic data: Enfield Field, NW Australia”
Presented by Sergey Shevchenko, SIS Exploration Pty Ltd
The Extended Elastic Impedance (EEI) concept has been used by the oil industry primarily for lithology and fluid prediction. We present a method of reservoir monitoring that calculates changes in pressure and saturation in a producing reservoir by applying EEI to time-lapse seismic data. The method uses time-lapse seismic difference data rotated to specific EEI χ angles which are optimised for the changes expected in a given reservoir. One angle is found to be appropriate to identify predicted changes in saturation, using fluid substitution models, while the other angle is found from rock-physics assumptions or laboratory measurements of fluid-pressure changes.
Our technique is tested using time-lapse seismic data for the Enfield oil field, in the North West Shelf, Australia, with estimates of optimal EEI rotation angles χ based on log data and Biot-Gassmann modelling for the fluid changes, and on rock physics models fit to measurements made on core samples for the pressure changes. Reflectivity and inversion domains were used using various approaches to test results qualitatively and quantitively.
The final calculated pressure and saturation maps predicted areas where changes in pressure and/or saturation changes were expected. It was successfully tested with two areas of changing the pressure from the well data, showing that our quantitative results are credible. Additionally, our results coincide with the Enfield operator’s maps for pressure and saturation predictions.

Presentation:
Melbana Energy in Cuba – an exploration success in the Caribbean

Venue:
Hilton Hotel Brisbane, 190 Elizabeth Street, Brisbane QLD 4000
Room 83, Level 8
(Detailed directions below)

Date & Time:
Thursday, 22 June 12:15 PM

Presentation Abstract:
In September 2015 Melbana Energy was awarded the Block 9 PSC, an onshore block on the north coast of Cuba which covers over 2,344 km2. The block is 140km east of Havana in a proven hydrocarbon system and on trend with the multi-billion barrel Varadero oil field. Cuba currently produces approximately 45,000 barrels of oil per day and 3 million cubic metres of gas. Oil production meets 50% of the domestic consumption, with the balance satisfied by imports. Most of the oil industry is currently operated by the national oil company, CUPET. The Canadian company, Sherritt International, has been producing oil in Cuba for over 25 years.
The geology of northern Cuba is dominated by complex fold and thrust belt geology which has encapsulated rich source rocks, fractured carbonate reservoirs, serpentinitic shales and ophiolites. Seismic data in Block 9 is limited to various vintages of 2D data of generally poor quality. Melbana has drilled two exploration wells to date in Block 9, the first well Alameda-1 was spudded in September 2021 and drilled to a depth of 4000m. This well encountered continuous oil shows from as shallow as 400m with oil regularly flowing over the shakers while drilling. Several high-pressure zones were encountered whilst drilling reflecting the intersection of separate pressure compartments bounded by various thrust faults. A total of 218m of net log pay was encountered (precluding zones which could not be logged due to adverse hole conditions). A total of 6.4 billion barrels OOIP with 362 mmbbls of P50 prospective resource have subsequently been independently certified at Alameda based on seismic mapping and the well result. The second well Zapato-1 reached a total depth of 3700m. Oil was observed flowing over the shakers at the top of the ophiolite sequence from a fault zone indicating access to a mature oil generative system below the ophiolites, unfortunately the well reached TD still within the ophiolites, above the anticipated reservoir section. A review of the gravity and magnetic model is underway to ascertain a more favourable location for a potential Zapato follow up.
A two well appraisal campaign designed with the prime objective to obtain a measure flow rate of the Alameda numerous discovery zones is on track to spud at the end of June 2023.

The Value of Knowledge Sharing in Bringing CCS Projects to Life
Presented by Conway Nelson (The International CCS Knowledge Centre)
Abstract

The capture and storage of CO2 (CCS) from heavy industry has long been recognized as a critical component of achieving a carbon-neutral and sustainable energy future. However, the deployment of large-scale CCS projects has lagged behind rates proposed by organizations like the International Energy Agency and the UN’s Intergovernmental Panel on Climate Change. Recent developments indicate a shift in this trend. The social and economic value of CCS is increasingly acknowledged, as well as its contribution to energy security and sustainability, leading to higher public support and capital investment. As a result, the global pipeline of CCS projects is growing, with the increase in potential capture capacity rising from 75 million tonnes per year in 2022 to 320 million tonnes per year in March of 2023.
Despite aspirations, only a handful of CCS projects have been built and brought successfully into operation. The reasons are multifaceted, including technical, engineering, economic, financial, and political challenges. To maximize the chances of success for current projects, it is imperative that lessons learned from previous experience are applied, to reduce risk, lower costs and improve the performance of the next generation of CCS technologies.
The International CCS Knowledge Centre is one of the world’s leading curators of knowledge and lessons from CCS projects across heavy-emitting industries including power generation, oil and gas production, mining, and cement, steel and fertilizer manufacturing. Using its unique expertise, the Knowledge Centre provides independent advice to help companies successfully navigate the myriad technical, economic, policy and stakeholder issues that accompany the development of major CCS projects. The Knowledge Centre’s experience is based in Canada, which is a world leader in CCS development with five of the 30 industrial-scale CCS projects globally, including the ground-breaking SaskPower Boundary Dam 3 CCS Facility (BD3 CCS facility), the world’s first fully integrated post-combustion CCS facility on a coal fired power plant.
SaskPower’s BD3 CCS facility has effectively captured and sequestered over 5 million tonnes of CO2 since 2014, with a 90% capture capability. As global efforts to reduce greenhouse gas emissions gain momentum, it becomes increasingly vital for there to be real-world examples of successful implementation of large-scale CCS technologies. The BD3 CCS facility provides those critical lessons learned and has paved the way for innovation, increased efficiency and lower costs in future iterations of the technology across all industries. It has proven the feasibility of CCS technology at a commercial scale and provides a framework for governments and companies considering implementation. From this experience, the Knowledge Centre has derived a set of technical, strategic and regulatory insights and lessons that are applicable to the next generation of large-scale CCS projects across heavy-emitting industries, and has developed a set of prioritized questions that potential project developers must ask in order to maximise the chances of a successful project.

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"
2023-06-29 12:00 - 14:30 (Australia/Adelaide) | Ayers House – Ballroom, 288 North Terrace, Adelaide, South Australia, 5000
A new 3D structural model for the Porgera Region, PNG Fold Belt: the integration of petroleum and minerals exploration methods.
Presented by: Gareth T. Cooper, Enigma Energy Services
Work by: Gareth T. Cooper, Kevin C. Hill, Peter Essy, Mark Haydon & Agnes Pokondepa

Abstract

The 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.
The 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).
This 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.
This 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.

An Integrated Static and Dynamic CCUS Modelling Case Study from the North Sea
Presented by Tito Lozada and Andres Bracho (Rock Flow Dynamics)
Abstract

In this presentation we utilize publicly available data from a North Sea field to build and simulate a Carbon Capture and Storage (CCS) model in tNavigator. The presentation highlights how to address issues such as data scarcity and methods for screening out areas for potential injector target selection. We will then take the model into simulation and visualize parameters critical to CCS such as plume behaviour, trapping mechanisms, and plume size. A geomechanics solver was also utilized to assess the seal integrity of the structural trap and the risk of potential fracture generation. The model was also taken into an integrated uncertainty study to assess the impact of operational and geological inputs on the total storage capacity of the formation.

PESA ACT/NSW July Technical Lunch
2023-07-11 12:00 - 14:30 (Australia/Sydney) | Castlereagh Boutique Hotel, 169 Castlereagh St, Sydney, NSW, 2000, Australia
Household renewable energy journey, and more
What is a VPP and how can you be part of one? Can you get electricity off the grid for free, or get paid for taking it? Can you as an individual trade electricity? What is VTG or VTH, and how will these revolutionise electricity supply in the future? Why is South Australia so far ahead in the renewables race, and how was John Howard involved? How will the transition to renewables work in Australia, and how long will it take? How much does it really cost to run an electric car? What percentage of electricity production is now renewable?
These and other questions will be addressed in this discussion of going all electric. Home solar systems provide the means to monitor one’s electricity generation and usage, at 5 minute intervals.
Comparisons of different periods (days, seasons, years) allow the user to evaluate, for example, the effect of La Niña on solar production, winter versus summer, and the need for backup from the grid, and to determine what device in your household is sucking up all that electricity. Even if you don’t have a solar system you can optimize your use of solar energy if you want to. Some weird and wonderful data displays from the Australian Energy Market Operator’s website will be shared, comparing state by state energy generation by power source, usage and price.

Recent Exploration in the Timor-Leste Frontier
Timor Resources, has re-commenced onshore hydrocarbon exploration in Timor Leste after a 50-year hiatus. This talk describes the challenges presented by the complex geology and the process of developing an understanding from the regional to the prospect scale. Timor Island is the product of an active continental collision, which has been studied by numerous academics for decades. Timor Resources has harnessed some of their ideas, added a few of our own, and recently acquired 2 seismic surveys and drilled 3 wells in the Suai Sub-Basin on the southern coast, including a deep “sub-decollement” play, first proposed in the 1970s. The talk will show the regional structure developed using gravity and outcrop data and then zoom in to the prospect scale for a look at the recent drilling results.

CCS Monitoring and Verification: Why and How?
Presented by Hadi Nourollah (CO2CRC)
Abstract

Monitoring and verification of CO2 plume is essential in understanding the effectiveness and potential risks associated with carbon capture and storage (CCS). Despite some degrees of ambiguity in the regulations for the monitoring requirements, all regulators require that the operator to monitor the injection, migration and stabilisation of the plume. 20+ years of post-injection monitoring itself can be a costly task which requires careful planning.
The essence of monitoring lies in the continuous assessment of the behaviour and movement of the CO2 plume within the geological storage site. This includes measurements of pressure, temperature, and saturation (or their changes) of the underground reservoir where the CO2 is stored. By monitoring these parameters, the operator can ensure that the stored CO2 is being contained as intended and is not leaking into the atmosphere or triggering any unwanted effects such as seismic activity.
Verification, on the other hand, focuses on confirming the accurate placement and containment of the CO2 within the storage site. This involves the use of various monitoring techniques, such as seismic surveys, well logging, and pressure testing, to assess the integrity of the storage reservoir and detect any potential leaks or migration pathways. Verification is crucial in ensuring the long-term safety and reliability of CCS projects.
Monitoring plans are very site specific, but the learnings can be carried over to other projects. This talk aims to introduce some elements of risking that are to be considered for any monitoring plan and how they may be addressed.

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
Presented by: John Cocker (Beach Energy)

Abstract:
Beach 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:
1. Provide the required geophysical data quality
2. Significantly alter the received anthropogenic sound levels (SPL and SEL)
3. Changes the impacts on benthic invertebrates via analysis of scallop and lobster specimens placed on the seafloor
This 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.
The 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.
Scallop 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.
The 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.

Digitalisation of a National Legacy Cuttings Archive – A Case Study from Norway and the Opportunity for the Australian Energy Sector
Presented by Edward Mortimer (Rockwash)
Abstract

The talk discusses NOROG. NOROG is a fully digital cuttings dataset of all released exploration wells offshore Norway.
Created through an industry consortium, the NOROG project used Rockwash’s proprietary technology to digitise 700,000+ samples from 1900 exploration wells offshore Norway for the NPD. We will discuss the process and data collection, then how the outputs are being used in O&G exploration, CCUS and AI/ML workflows.

PESA ACT/NSW August Technical Lunch

Federal Government False Narrative About Cause of East Coast Gas Supply Shortage, Gas Price Cap and Gas Reservation
I 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.
The 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.
Gas 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.
Misinformation is prevalent in politics, the media and Government discussions about gas prices. Evidence-based facts are overlooked in favour of emotional narratives.
The 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.
The 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.
The 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.
The 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.
The 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.
The 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.
Contrary 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.
There 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.
Legislative power for petroleum exploration and production in onshore areas, including State-controlled waters, is governed by each State and Territory under the Australian Constitution.
There 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.
The 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.
New 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.
The 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.
Application 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.
Petroleum 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.
The 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.
There 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.

Flexible Solutions for both CCS Measurement, Monitoring, and Verification (MMV) and Offshore Windfarm Developments
Presented by Andrew Long (PGS)
Measurement, 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.
Likewise, developing ground models for offshore wind turbine placement demands a comprehensive approach that addresses various geotechnical, geophysical, regulatory, and stakeholder aspects.
A 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.
This talk comprises four stages:

I 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.
I outline an efficient workflow for CCS site screening, focusing on Container and Containment elements.
I 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.
I describe subsurface characterization (both CCS and Wind) and monitoring solutions (for CCS) that leverage innovations from stages 1 and 3.

The PESA SA-NT Branch will be hosting a 5-day structural geology training course by Professor Ken McClay from Monday 21st to Friday 25th of August. Bookings are now OPEN!!
This five-day classroom course consists of lectures, seismic interpretation exercises and case histories. The course presents modern concepts of structural geology focused on fault and fold systems that form hydrocarbon traps in sedimentary basins. Emphasis is placed on the integration of data in order to determine the 4D evolution of structures, their seismic expressions as well as utilising case histories and natural examples that can be analogues for sub-surface hydrocarbon traps.
The lectures are extensively illustrated with field examples, remote sensing examples, seismic sections, conceptual models and in particular analogue models of fault systems – many models are shown as movies that demonstrate the progressive evolution of fault and fold systems. Practical exercises and examples are excellent seismic examples of structural styles in a large format A3 workbook.
Key Themes of the training are given below, and more details are in the attached Programme:
1. Fault systems in sedimentary basins – Tectonic regimes; fault mechanics; fault geometries; fault growth & segmentation patterns
2. Extensional fault systems – Planar extensional faults – 2D & 3D geometries; rift systems & passive margins; folding associated with extension
Listric & ramp-flat listric extensional faults; delta tectonics – hydrocarbon systems
3. Inversion tectonics – Positive inversion systems; inverted rift basins & thick-skinned fault systems, hydrocarbon systems in inverted terranes

Machine Learning and Intelligent Augmentation Applied to Legacy Subsurface Data
Presented by Jess Kozman (Katalyst Data Management)
Abstract

Recent 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.
We 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.
We 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.

PESA SA/NT August Technical Luncheon "Critical Minerals in SA – The road to net zero"
2023-08-24 12:00 - 14:30 (Australia/Adelaide) | Ayers House – Ballroom, 288 North Terrace, Adelaide, South Australia, 5000
Critical Minerals in SA – The road to net zero
Presented by: Bronwyn A Camac (Geological Survey of South Australia)

Abstract

For about 150 years, the use of petroleum products has driven world economies and is the greatest influence on quality-of-life improvement.
Before 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.
Our 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.
But 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.
This 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.
This is space where the mineral resource industry and the energy resource industry collide!
Critical 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.”
South 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.

CCS Knowledge Transfer Series: Installment 1

Welcome to the CCS Knowledge Transfer Series – ETSIG
Introduction to the CCS Knowledge Transfer Series – Themes, Framing Remarks and the Challenges of CCS – Charles Jenkins (CSIRO)
CCS, and its cousins CCUS, BECCS and DAC are all aspects of the same technology and are becoming increasingly vital to control and reverse atmospheric concentrations of CO2. 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.
Site Selection and Characterisation – What’s Different About CCS? – Tess Dance (CSIRO)
Abstract

The 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”?
