SUMMARY:2025 PESA WEBINAR SERIES: What happened to CO2 storage in the Great Artesian Basin? (Navigating gas water rock reactions and potential groundwater impacts
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 \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. \nWhat happened to CO2 storage in the Great Artesian Basin? (Navigating gas water rock reactions and potential groundwater impacts)\nPresented by Dr Julie Pearce (University of Queensland) \nAbstract \n\nCarbon dioxide geological storage is one option to enable Australia to reach net zero. Several carbon storage demonstration sites are undergoing feasibility studies and environmental impact assessment internationally and in Australia. Very recently CO2 storage in the Surat Basin gained a lot of media and political attention – the QLD government has now put a ban on CCS in the geographical extent of the QLD Great Artesian Basin (and below it). The reservoir that was being assessed is in a deep (~2300 m)\, brackish\, unpotable part of the Precipice Sandstone. However\, the broader formation is an aquifer of the GAB\, therefore stakeholders were sensitive to potential environmental impacts. The previous demonstration site that underwent assessment was further north in the shallower part of the Precipice Sandstone (~1200 m). In that Glenhaven site the West Wandoan 1 well was drilled for the feasibility study\, and the reservoir had fresh groundwater. This presentation details part of the experimental and field sampling components of the underlying research\, including CO2-water-rock geochemical reactions\, metal mobilisation\, and creation of a reactive transport model. \n

SUMMARY:PESA ACT/NSW June Technical Talk
DESCRIPTION:Recent Advances in Faulting and Folding in the NSW Coal Fields: Implications and Observations on Fault Hydrogeology\nUnderstanding the impact of subsurface developments on groundwater is one of the key uncertainties for many resource projects. It is common for opponents to invoke faults as an existential threat to aquifers and groundwater systems. \nWhile minor faulting is common within a development\, the resource is generally relatively unfaulted and may be constrained by faults. Generally\, groundwater models used to support environmental impact statements cover an area wider than the development and often include faults. \nA simple set of workflows and schemas will be presented that can be used to characterise and understand the kinematics of faulting geologically. The hydrogeologic understanding of faults is intimately related to how they crosscut and displace aquitards\, aquifers\, and groundwater resources. These workflows will be illustrated using case studies from the Sydney and Gunnedah basins. \nParticular care must be taken when reviewing data and drawing inferences. Sound geological data and principles must be used to parameterise the hydrogeology of faults. A relatively small amount of work done early\, with the appropriate representation of results\, will ease future developments and expansion.

SUMMARY:PESA WA June Technical Lunch: The Renaissance Tour: A revival of frontier basins with data-driven exploration
DESCRIPTION:Hosted with thanks to our Platinum sponsor SLB: \n  \n \nGold Sponsors IKON Science: \n \n  \nand Silver Sponsors Delft\, Qeye and Task Fronterra Geoscience: \n                       \n\nPESA WA invites you to our technical luncheon on Thursday 19th June.\nThe Renaissance Tour: A revival of frontier basins with data-driven exploration\nPresented by Lauren Found (Searcher)\n\nAs the energy exploration landscape shifts and evolves\, so too does the thinking around the basins we investigate. Advancing seismic technology in the last decade has allowed for a fresh perspective on frontier and previously discarded basins\, with the shifts in thinking yielding billions of barrels of results. \nIn this world tour of frontier basins\, crustal architecture\, source rock presence and reservoir fairways are explored with direct observations from modern\, long-offset seismic data. The deepwater Gulf of Papua had its crustal model challenged and reinterpreted thanks to long-offset 2D seismic acquisition\, allowing for the imaging of large-scale crustal structures. Beneath the salt of the Scotian Basin\, reservoir fairways are imaged in detail and de-risked thanks to Wide Azimuth Seismic Acquisition\, and further south to the conjugate Orange-Pelotas Basins\, high-resolution 3D and Ultrafar AVO analysis reveals a world-class source rock\, observable and mappable on both sides of the margin\, despite being proven only on one side to date. \nTicket Prices:\nMember (Early Bird): $69.00 \nConcession Member [Retired or Hardship]: $59.00 \nStudent Member: $10.00 \nGraduate Member: $20.00 \nNon-Member: $99.00 \nMember (Non-Early Bird): $79.00 \nEarly bird\, Concession\, Student and Graduate Member pricing ends Thursday (1 week prior) at 5pm (AWST). All ticket sales close at 5pm Tuesday (2 days prior). \n

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 ACT/NSW July Technical Talk
DESCRIPTION:Kenmore: A Case Study for Static Modelling in a Mature Oil Field\nThe Kenmore field has been producing oil since 1985 and is moving to late field life. Several work-over opportunities existed\, with Kenmore-43\, a previously cased and suspended but yet to be completed well\, identified as one of the best candidates in the field. Focusing on the Jurassic Basal Birkhead and Hutton intervals\, a geological model was built to capture the possible range of outcomes if Kenmore-43 were to be perforated. The modelling work was closely integrated with the simulation results and was continuously refined to obtain the best possible history match. The work identified Kenmore-43 as a viable economic opportunity\, which followed through with a very successful workover.

Once registered with the webinar software you will receive a reminder e-mail 1 hour beforehand. \nThe Book Cliffs of Eastern Utah – A Virtual Field Trip To A World Class Reservoir Analogue\nPresented by Professor John Howell (University of Aberdeen) \nAbstract \n\nThe Cretaceous Blackhawk Formation which crops out in the Book Cliffs of eastern Utah (USA) provides over 150 km of continuous exposures through a prograding clastic wedge. Since the 1980’s these outcrops have been central to the development of sequence stratigraphic and provide unparalleled insight into large scale geometries and architectures in shallow marine and coastal plain reservoirs such as the Brent Group\, the Niger Delta and the Jurassic clastic deposits of the Caernarvon Basin. \nRecent advances in digital outcrop acquisition techniques\, including the use of drones to acquire photogrammetric 3D models has revolutionised reservoir analogue studies. In this presentation a dataset which includes over 100 km of virtual outcrop data will be used to provide a fully integrated Virtual Fieldtrip and highlight the use of this technology to provide quantitative analogue data\, illustrate correlation strategies\, provide input for reservoir models and illustrate links between modern and ancient systems. We will also discuss recent analysis of the perception of virtual field trips and demonstrate their pros and cons with respect to different audiences.

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:Reservoirs\, seals and pay: learning to think like hydrocarbon
DESCRIPTION:PESA SA Training Course\nReservoirs\, seals and pay: learning to think like hydrocarbon\nJohn Kaldi\nEmeritus Professor & CO2CRC Distinguished Scientist\nUniversity of Adelaide\nThis practical workshop-style course demonstrates how basic geological and engineering data can be used to evaluate reservoir rock quality\, fluid saturations and contact depths\, transition zone thickness and seal capacity (i.e. the maximum hydrocarbon or CO2 column a seal can hold before it leaks). It also demonstrates the geological controls on capillary pressure and relative permeabilities and how to use these to approximate recovery efficiency during primary or secondary recovery of hydrocarbons and storage efficiency in CO2 storage projects.  This popular course has received extremely favorable reviews when presented for AAPG\, SPE and PESA and as an internal training course for several major oil and gas companies as well as several generations of University of Adelaide students. \nThe course comprises lectures\, case histories and several hands-on exercises. Participants will work in teams for most exercises. \n  \nEvent Details: \nAugust 12th and 13th 2025 (Tuesday and Wednesday) \nFrom: 9am- 5pm \nVenue: Ayres House Adelaide \nWe look forward to your participation in this enriching training session! \nPlease note that ticket sales will close today at 5:00 PM.

SUMMARY:PESA WA August Technical Evening: Two Talks - Back water effects on Fluvial reservoirs and Neoichnology of the De Grey ephemeral river delta
DESCRIPTION:Hosted with thanks to our Platinum sponsor SLB: \n  \n \nGold Sponsors IKON Science: \n \n  \nand Silver Sponsors Delft\, Qeye\, Totum Compliance\, Core Laboratories and Task Fronterra Geoscience: \n                       \n       \n\nPESA WA invites you to our technical evening on Thursday 14th August.\nQuantifying the backwater effect on Fluvial reservoirs\nPresented by John Holbrook (Dept. of Geological Sciences\, Texas Christian University)\n\nThe backwater effect is an emerging tool for predicting reservoir volumes and heterogenicity in fluvial systems.  It scales channel-belt width\, tidal impact\, and bar development to the channel size and the distance from the coast\, two measurable parameters.  The backwater effect (i.e. adjustments in open-channel flow as a response to proximity of standing water) is used to predict down-dip changes in morphodynamics and consequent sediment distribution on fluvial systems. However\, there is currently no standardized method to obtain input parameters to estimate backwater length\, nor where to measure these variables\, for both modern and ancient settings. This study reviews existing methods for estimating backwater lengths in both settings and proposes workflows to minimize ambiguity in the results. The proposed workflows are prioritized based on practicality\, accuracy\, and smallest uncertainty ranges and allow different data types as input parameters. For the first time\, applying multiple methods to obtain backwater length estimates is tested\, both on a modern and ancient river system. In the modern case study\, the riverbed intersection with sea level matches previously documented major changes in sedimentary trends. However\, backwater lengths based on h/S (h = bankfull thalweg channel depth\, S = slope) plot downstream of this zone which is characterized by major changes\, when input parameters are derived from discharge and grain size. Therefore\, we recommend obtaining bankfull thalweg channel depth from a cross-sectional profile if backwater length is estimated based on h/S. In the ancient case study\, bankfull thalweg channel depth derived from fully preserved single-story channel fill and slope based on Shields’ empirical relation with grain size\, match changes in fluvial architectural style interpreted as a result of backwater effects. This review is a critical step forward in discussing and acknowledging the uncertainties and ambiguity in obtaining the necessary input parameters to estimate and compare modern and stratigraphic backwater lengths. The proposed workflows facilitate comparability and applicability of future backwater length estimates and subsequent interpretations of the hydrodynamic environment and resulting stratigraphic record. Potential scaling relationships between the backwater length\, sedimentary trends\, and avulsion nodes make this of key importance as the latter two also play a crucial role in devastating floods when rivers change course. \nNeoichnology of the De Grey Ephemeral River Delta\, Northwest Coast\, WA: Proxies for Environments\, Physicochemical Conditions\, and Climate in Deep Time\nPresented by Steve Hasiotis (Dept. of Geology\, The University of Kansas)\nThe neoichnology of the alluvial plain\, delta plain\, and proximal delta front settings of the dryland\, ephemeral De Grey River and its wave-dominated delta clearly show diagnostic patterns of plant and animal traces (and diversity)\, lithofacies\, soils\, groundwater profiles\, and salinities controlled by the climatic setting. The climate is hot arid (Köppen BWh)\, with annual rainfall falling between December and June of 311.5 mm (avg) but is subject to large variations because of erratic cyclones. The river typically flows only after seasonal rainfall events generated by tropical\, monsoonal cyclones or winter storms. These highly variable events are also associated with significant storm-wave reworking of the proximal delta front and lower delta plain. This research is timely because Cyclone Zelia\, strengthening to category 5 but making landfall as a category 4 at De Grey\, will provide a glimpse into how a dryland river–delta system and its physicochemical characters are impacted by major storms. \nPrior to Zelia\, alluvial plain channels are mostly devoid of water and water holes have fresh (<0.5 ppt) to lower oligohaline (< 2 ppt) salinities; mole cricket traces are abundant along the margins of these waterbodies\, with some vegetation along the margins and at various positions in the channels proper. The alluvial plain itself contains plant roots\, termite and ant nests\, goanna and smaller reptile and mammal burrows. The delta plain contains traces produced by terrestrial and marine fauna; plants and terrestrial fauna dominate overbank deposits\, whereas marine invertebrate and vertebrate fauna dominate the distributary channels\, varying from upper oligohaline (4–5 ppt) to hypersaline (50 ppt) in salinity. Supratidal areas contain mangroves and are dominated by a variety of crab\, polychaete\, and other vermiform animal burrow\, which increase in diversity to the intertidal areas and have the highest salinities. Intertidal settings are dominated by tidal processes and bedforms with a variety of crab\, clam\, gastropod\, polychaete\, and vermiform animal burrows in hypersaline conditions. \nThis research is important because trace fossils and paleosols of ancient fluvial–deltaic deposits can help distinguish between these systems deposited under drylands (ephemeral) vs. seasonal (intermittent) vs tropical (perennial) climate settings based on modern analogs. For example. most often the trace fossil-lithofacies-pedofacies associations preserved in core are very useful to improve interpretations of the degree of lateral and vertical continuity of paleoenvironments – continental vs transitional vs marine – that are used to interpret reservoir geometry and continuity. \nTicket Prices:\nMember: $35.00 \nConcession Member [Retired or Hardship]: $30.00 \nGraduate Member: $20.00 \nStudent Member: $10.00 \nNon-Member: $50.00 \nConcession\, Student and Graduate Member pricing ends Thursday (1 week prior) at 5pm (AWST). \n

In order to address these challenges\, we developed two novel in-situ laser-based methods that have the potential to quickly and accurately resolve these processes. The first method provides a tool to date clay phases in shales using Rb–Sr geochronology. We show that the Rb–Sr isotopic system in shales is sensitive to temperatures equivalent to the oil-gas window. The second technique demonstrates an approach for dating carbonate formation using U–Pb geochronology via a laser isotopic mapping approach. The laser rasters can be compiled into interactive maps\, and this spatial and geochemical information can be used target multiple generations of carbonate mineralisation. Records of natural carbonate precipitation can be used as an analogue for assessing the potential of host rocks for carbon capture and storage.\n\nEvent Details:\nThursday 28th August 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\, 25th August 2025 \nAny late bookings will incur an additional $20 fee.
