SUMMARY:Basins Workshop 2025
DESCRIPTION:Basins Workshop 2025 \n\n\nThe 2025 Basins Workshop will take place on Monday 1 and Tuesday 2 December 2025 at Curtin University\, Perth in association with PESA WA Branch.  The aim of the workshop is to provide an informal forum for the exchange of insights and ideas regarding the evolution of sedimentary basins in Australia and around the world\, and the diverse resources they contain\, including hydrocarbons\, minerals\, geothermal energy\, natural hydrogen\, and the potential for CO2 and hydrogen storage. \nTalks are limited to 10 minutes in duration\, with ample time for discussion\, so we are looking for thought provoking ideas\, rather than polished conference presentations. To participate all you need to do is to send the title of your proposed presentation to basinsworkshop2025@gmail.com by Friday 17 October 2025 – abstracts and/or written papers are not required. \nThere is no cost for registration\, but in the first instance participation is restricted to those expressing interest in making a presentation (whether or not your presentation is finally selected for inclusion in the programme).  Additional places will then be made available to co-authors and others interested in attending\, according to demand.

SUMMARY:PESA QLD: Technical Evening\, November 19: Henry W. Posamentier on 'Recent applications of seismic geomorphology/stratigraphy'
DESCRIPTION:PESA Queensland welcomes 2025 PESA Distinguished Lecturer\, Henry W. Posamentier to present a technical evening presentation on Recent applications of seismic geomorphology/stratigraphy: Deep-water deposits of the Bay of Bengal and the Norwegian Sea. The technical evening will be held at the Transcontinental Hotel. \nDue to the significant crossover with our peer society ASEG (Australian Society of Exploration Geophysicists)\, ASEG members are welcomed to attend at PESA member pricing. \nSpeaker travel and accommodation has been supported by Santos Ltd. \n\n\n\nPresentation:\nRecent applications of seismic geomorphology/stratigraphy: Deep-water deposits of the Bay of Bengal and the Norwegian Sea\n\n\nVenue:\nTranscontinental Hotel\, 482 George St\, Brisbane City QLD 4000\n\n\nDate & Time:\nWednesday\, 19 November 5:15 PM for 6:00 PM Start\n\n\n\n\n  \nRecent applications of seismic geomorphology/stratigraphy: Deep-water deposits of the Bay of Bengal and the Norwegian Sea\nHenry W. Posamentier\nThis presentation will document the seismic stratigraphic and seismic geomorphologic expressions of deep-water deposits of the Bay of Bengal and the Norwegian Sea. They comprise both turbidites as well as mass transport deposits. The turbidite deposits from the Bay of Bengal include leveed channel complexes\, terminal fans\, and overbank sediment waves. With respect to terminal fans\, there are those that terminate basinward of leveed channel systems and are relatively large\, and those that are deposited late within a lowstand cycle of deposition and are confined between the levees of precursor larger channels\, and are relatively small. Intra-basinal channels (i.e.\, channels that start and end on the basin floor) are observed within abandoned meander loops as well as interchannel overbank terrains. These intra-basinal channels are characterized by low sinuosity and likely are mud-filled with no exploration potential.  \nMass transport deposits from the Norwegian Sea include flows\, slumps\, and slides\, as well as isolated outrunner blocks. These deposits are associated with significant substate erosion up to 250m. The outrunner blocks are observed in clusters\, generally in radiating patterns down-system. Some of the outrunner blocks at the termini of erosional furrows are associated with sediment tails orthogonal to the direction of transport\, indicating bottom current direction from southwest to northeast. In addition\, volcanic intrusive deposits will be documented. These intrusives comprise both dikes and sills. Some of the dikes are associated with laccoliths in the shallower section.   \n  \n\n  \nTickets for the Technical Evening Talk can be purchased below. \nEarly Bird ticket pricing will be available until Wednesday\, 12 November 5:30 PM – to avoid disappointment please register before this time. \n\n\n\n\nEarly Bird Ticket Price\nStandard Ticket Price\n\n\n\n\nMembers – $35\nNon-Members – $45\nStudent / Retired Members – $25\nMembers – $45\nNon-Members – $55\nStudent / Retired Members – $35\n\n\n\n\n  \nSpeaker travel and accommodation supported by Santos Ltd.

SUMMARY:PESA WA - Seismic Geomorphology and Seismic Stratigraphy: Fundamentals and Workflows
DESCRIPTION:Supported by Santos Ltd.\nPESA WA – Seismic Geomorphology and Seismic Stratigraphy: Fundamentals and Workflows\nLed by Henry W. Posamentier PhD (Consultant)\nCourse commences at 0900-0930am Thursday: Arrivals\, registration\, tea & coffee. \nObjectives \nThis course is designed to enhance interpretation skill sets with regard to geologic interpretation of seismic data. The overall objective is to present seismic interpretation methods/workflows focused on seismic stratigraphy integrated with seismic geomorphology\, aimed at reducing risk with regard to prediction of lithology\, reservoir compartmentalization\, and stratigraphic trapping potential in exploration and production. Specifically\, the participant will be shown: \n\nworkflows designed to facilitate extraction of stratigraphic insights from 3D seismic data\ntechniques for 3D seismic geomorphologic/stratigraphic analyses\nnumerous examples of various depositional systems in various depositional settings (i.e.\, fluvial\, marginal marine\, deep-water\, shallow-water carbonates)\nintegration of sequence stratigraphic concepts\ndiscussion\, with examples\, of pitfalls in interpretation\n\nContent\nThe application of seismic geomorphology and seismic stratigraphy to exploration and field development is a natural consequence of the advent of high-quality and increasingly more affordable and widespread 3D seismic data currently available. Integrating analyses of plan view (geomorphologic) and section view (stratigraphic) images can significantly enhance predictions of the spatial and temporal distribution of subsurface lithology (reservoir\, source\, and seal)\, compartmentalization\, and stratigraphic trapping capabilities\, as well as enhanced understanding of process sedimentology and sequence stratigraphy. \nParticipants in the course will be exposed to seismic geomorphologic/stratigraphic workflows\, which involve 1) initial reconnaissance through 3D volumes with various slicing techniques using a variety of different seismic attribute volumes including full stack reflection amplitudes\, near and far stacked amplitude volumes\, and coherence volumes\, as well as opacity rendering\, 2) focus on features of geologic interest and further investigate through a combination of detailed slicing\, interval attributes\, horizon picking and amplitude extraction\, horizon illumination\, etc.\, and 3) comprehensive integration of seismic geomorphologic analyses with seismic stratigraphic analyses\, whereby the plan view is integrated with the section view to ensure a consistent interpretation. 4) integration and application of sequence stratigraphic concepts to facilitate data interpretation. \nCourse lectures will involve both PowerPoint presentations as well as interactive demonstrations of the interpretation of 3D seismic data. A wide variety of depositional settings will be shown\, ranging from non-marine to marginal marine\, shelf and deep water\, and will include both clastic as well as carbonate depositional environments. Concepts as well as applications pertaining to seismic-based analyses of depositional systems will be covered in detail. \n  \nPrices: \nMembers:                     $660 \nStudents:                       $200 \nNon-Members:             $1000 \nThis course will be held at the Pan Pacific hotel (207 Adelaide Terrace\, Perth).  Morning tea\, lunch and afternoon tea will be provided as part of the course cost. \n  \n

SUMMARY:2025 Australian Natural Hydrogen Conference -Adelaide Hills- PESA discount applies
DESCRIPTION:Hundreds of millions of dollars have been committed worldwide to the hunt for natural hydrogen. \nMany more countries and companies are trying to commercialise one of the most abundant and cost-effective forms of hydrogen as the world continues the drive to carbon zero. \nSince the inaugural Natural Hydrogen Association of Australia conference in 2024\, the game has changed. Where are the new natural hydrogen targets; who are the prime movers; what have we learnt from the latest drilling programs; and how have the technical approaches to exploration morphed? \nThis is a fantastic opportunity for interested parties to learn how much closer we are to having at our fingertips a new tool in the carbon zero war. \nThe conference will span 3 days and\, depending on demand\, there could be events on another 2 days. \nThe official conference will begin on Tuesday October 21 with an add-on afternoon workshop on specific technical topics (agenda to be confirmed) and an evening icebreaker session. The official conference is on the Wednesday and Thursday (Oct 22-23)\, with a informal event on the Wednesday evening. \nAs well\, if there is enough demand\, organisers are considering a wine tour of some of the world-renowned wineries of the region on the Monday (Oct 20) and a field trip on Friday (Oct 24). As South Australia is one of the hotbeds of natural hydrogen exploration in this country\, that would be either a core store visit or a trip to one of the sites where natural hydrogen has been identified. \n  \nPESA Member Discounts\nWe welcome interested PESA members to our conference and are offering 10% off the registration pricing. Tickets on sale here: 2025 ANHC. \nYou must be logged in to the PESA website to view the instructions on how to get your discount. \n

SUMMARY:PESA WA October Technical Lunch: Fault timing and depocentre development in the northern Perth Basin
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 16th October.\nFault timing and depocentre development in the northern Perth Basin\nPresented by Chris Watts (School of Earth and Planetary Sciences\, Curtin University)\n\nDespite extended periods of exploration in the Perth Basin spanning decades\, the timing of fault activity\, and shifts in depocentre development remain unclear\, especially for intra-basinal faults. Multiple phases of rifting with variable extension directions during the Paleozoic and Mesozoic resulted in a series of predominantly NNW–SSE trending graben and half-graben extending from the Southern Carnarvon Basin in the north\, through the Perth Basin in the south. Two regions of greater structural complexity are indicated by gravity and magnetic data along the margin\, one of which occurs within the northern Perth Basin and the other between sub-basins of the Southern Carnarvon Basin. Recently acquired seismic surveys that better image the pre-Mesozoic stratigraphy in the northern Perth Basin\, paired with legacy seismic and well data have allowed the investigation of fault timing and show a progressive southward shift in fault activity and depocentre location from the late Carboniferous through to the Early Cretaceous\, and that some faults\, despite having different similar orientations\, initiate at different times. Of particular importance is a change in extension direction in the late Triassic and early Jurassic that allowed the development of E-W trending faults. \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).

SUMMARY:PESA WA - The Mungaroo - Brigadier Depositional System\, Northwest Shelf Australia: A Fluvial-Deltaic Reservoir Core Workshop
DESCRIPTION:Supported by Santos Ltd.\nPESA WA \n3rd October 2025\, 9:00 – 1600 Carlisle Core Library\nThe Mungaroo – Brigadier Depositional System\, Northwest Shelf Australia: A Fluvial-Deltaic Reservoir Core Workshop\nThe Late Triassic Mungaroo and Brigadier Formations in the offshore Northern Carnarvon Basin\, NWS\, Australia\, are the deposits of enormous very low-gradient rivers that fed an intracratonic basin. In such a very low gradient setting\, the rivers expand across a broad distributive deltaic plain\, as sediments spill out of channels into vast interdistributary bays. River distributaries reaching the coast deposit thin\, asymmetrical wave-reworked delta sands. Avulsion of rivers laterally over hundreds of kilometres shifts the locus of deposition\, allowing weak waves and tides time to rework sediments at bay mouths into shoreface sands with tidal inlets. Sea level variations can cause shorelines to shift long distances across these low-gradient alluvial-deltaic plains. \nStandard facies models for fluvial-deltaic systems\, which generally focus on higher gradient settings\, do not provide a suitable template for predicting subsurface facies variations within the Mungaroo and Brigadier deposits. In higher gradient settings\, a river crosses thin delta top deposits to feed a thick\, basinward-thickening deltaic wedge\, with the bulk of river-sourced sediments spread down steep deltaic clinoforms offshore. In very low-gradient settings\, a river loses the competency to carry its sediment load to the coast\, and the bulk of the sediment is extracted on the deltaic plains. Deposits in the expanding network of channels\, on floodplain splays and brackish bay deltas\, and within thin shoreline successions define a unique facies mosaic. \nIn this workshop\, participants can observe the low-gradient fluvial-deltaic facies of the Mungaroo and Brigadier systems in core from the Northwest Shelf of Australia. Brief presentations will introduce conceptual models\, set the stage\, and provide a seismic-scale view of this system. Deposits of the major river in more proximal areas of the system are studied in core from Clio and Saty fields. Lower delta plain and river-dominated bay delta deposits are examined in core from Chandon field. Wave-reworked shoreline deposits will be visible in core from Wheatstone field. Together\, these cores provide a sampling of the facies mosaic deposited by these low-gradient systems. By the end of the workshop\, participants will have gained a better understanding of facies models for low-gradient fluvial-deltaic systems. Mungaroo and Brigadier deposits host world-class hydrocarbon reserves\, which require advanced facies predictions to support subsurface modelling and development predictions. Low-gradient fluvial-deltaic facies are essential components of most shallow marine clastic wedges\, particularly during the early highstand when deltaic systems prograde on top of transgressive shelf deposits. The workshop offers participants a broader perspective on fluvial-deltaic facies models\, extending beyond the standard textbook examples. \n  \nSchedule \n9:00 ─ Safety & Introductions \n9:20 ─ Topic #1: Fluvial deposit architecture defined by process models and concepts (Willis: 20 min) \n9:40 ─ Topic #2: Mungaroo-Brigadier System (Lang: 20 min) \n10:00 ─ Topic #3: Mungaroo fluvial hierarchy and down-basin variations (Payenberg: 20 min) \n10:30 ─ Tea break \n10:45 ─ Start Core #1: Mungaroo fluvial (Clio 2 and Satyr 3) \n11:45 ─ Discussion (core review) \n12:00 ─ Lunch \n12:45 ─ Short topic #1 (20 min plus Q&A) High- vs low-slope systems & asymmetric deltas \n13:10 ─ Start core #2: Chandon 2 (Mungaroo lower delta plain and delta front) \n14:00 ─ 14:15 ─ Tea break \n14:30 ─ Start core #3: Wheatstone 2 BCH1ST1 (Brigadier asymmetric wave-influenced delta) \n15:30 ─ Wrap-up discussion \n15:45 ─ Finish \n16:00 ─ Core store closes \nOrganisers: Dr. Brian Willis (Consultant) Dr. Tobi Payenberg (Chevron) & Prof. Simon Lang (UWA) \nHard limit of 30 attendees.  \n  \nCost:  \nPESA Members:  $250 \nPESA Student Members $100 \n  \nThis event is for PESA WA members only.

SUMMARY:PESA WA October Technical Evening:  Three-Dimensional Architecture of Wave-Dominated Delta Deposits
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 2nd October.\nSupported by Santos Ltd.\nThree-Dimensional Architecture of Wave-Dominated Delta Deposits\nPresented by Brian J. Willis (Willis Geoscience)\n\nNew numerical wave-influenced delta depositional models are challenging long-held rational for interpreting sea level variations recorded by wave-dominated shallow-marine successions. Shallow-marine\, wave-dominated deposits (parasequences) are generally inferred to exhibit a decrease in wave energy and grain size with increasing water depth and to occur in facies belts that are laterally continuous for long distances along strike. Bedding geometry and vertical facies successions within these parasequences are interpreted in relation to a prograding equilibrium shoreface profile (cf. Bruun rule) and a gradual upward-coarsening facies progression (cf. Walther’s law). Sea-level fall is commonly inferred to generate a sharp-based shoreface succession\, characterized by an abrupt vertical transition from heterolithic lower shoreface to sandy upper shoreface deposits across a marine erosion surface. A truncated vertical shoreface succession\, capped by a marine erosion surface\, is inferred to record significant wave ravinement during sea level rise and transgression. \nThree-dimensional\, process-physics-based\, coupled hydrodynamic-morphodynamic wave-influenced delta models suggest that wave-dominated deltas will develop a sandy shoreface inner clinoform dipping from the subaerial delta plain to a relatively flat wave-scoured subaqueous delta top\, which is laterally separated from a muddier delta front outer clinoform that dips from the subaqueous delta top edge to the shelf floor. As these systems prograde\, deposits of these dual-clinoforms will become vertically stacked and will be separated by a regressive surface of marine erosion formed on the subaqueous delta top. Grain-size contrasts between these vertically stacked clinoform deposits reflect differences in sediment-transport directions and sorting under river- and wave-driven littoral currents along the coast\, and cannot be uniquely related to sea-level changes. Gradual vertical facies successions develop where waves are less effective at reworking river-supplied sediment alongshore. In contrast\, sharp-based shoreface deposits record more effective wave separation of sands onto the shoreface clinoform as muds are preferentially transported offshore onto the subaqueous delta clinoform. \nThe continuity of a regressive surface of marine erosion over many tens to hundreds of kilometres across mid-shelf regions of some stratigraphic sequences reflects a gradual lateral shift in the position of littoral current erosion on a subaqueous delta top. Timelines cross such vertical lithic discontinuities throughout the extent of a prograding deposit\, and the regressive surface of marine erosion thus has little chronostratigraphic significance. The model results are used to suggest: 1) Characteristic strongly asymmetric wave-dominated parasequences suggest common river avulsion at the start of transgression\, 2) Observed down-dip transitions from “gradual-based” to “sharp-based” shoreface deposits might record reduced sediment supply to the coast relative to rates of longshore drift as the system expands toward its auto-retreat limit\, rather than transitions from normal to forced regression\, and 3) Regional “top-truncated” shoreface successions might record progradation of dual-clinoform shorelines with wide deviation in net direction of regional sediment supply and shallow-water wave transport\, rather than significant regional transgressive ravinement. The results of these models suggest caution in inferring sea-level changes from the character of vertical facies changes observed in individual well logs and isolated outcrop exposures. The models suggest new facies relationships that require testing in modern systems\, outcrops\, and subsurface examples. \nTicket Prices:\nMember: $25.00 \nStudent Member: $10.00 \nNon-Member: $50.00 \nStudent Member pricing ends Thursday (1 week prior) at 5pm (AWST). \n

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

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).

SUMMARY:PESA WA and CCUSNA - Perth Basin from a CCS Perspective Core Workshop
DESCRIPTION:PESA WA and CCUSNA\n10th of June \, 9:00 – 1600 Carlisle Core Library\nPerth Basin from a CCS Perspective\nSpend a day at the Perth Core Library considering how our collection of cores help us to understand CCS targets in the Perth Basin. We will delve into the importance of characterising seals\, the influence of reservoir heterogeneity vs homogeneity and how diagenesis impacts pore geometry. \nThe Cattamarra Coal Measures ranks highly as a saline aquifer CCS reservoir target as it has excellent net-to-gross and reservoir quality over thick intervals. The fluvio-deltaic depositional environment of this unit provides for significant heterogeneity to promote lateral migration of the injected plume. Diagenesis impacts reservoir quality as a function of depth of burial and reservoir temperature. These impacts will be demonstrated with a suite of cores from various structural settings in the basin. \nThe Dongara Sandstone has attracted attention as a potential CCS reservoir target in depleted fields. Due to the homogeneous nature of the shoreface facies\, this may be the best interval to study the impact of hydrocarbon charge on diagenesis and porosity preservation. \nCores of sealing lithologies are rare but provide important constraints when characterising a CCS storage formation. A suite of cores from the Kockatea Shale and Hovea Member will be investigated to understand variations in facies and the impact of diagenesis on geomechanical properties. \nThe workshop will be led by Julie Cass and Arthur Mory (GSWA) with assistance from Simon Molyneux (Molyneux Advisors) and Jeremy Prosser (Task Fronterra). Simon will show how cuttings can be utilised to investigate these same reservoir quality controls and Jeremy will illustrate how image log data compliments analyses of core and cuttings. \nOrganiser: Julie Cass and Arthur Mory (GSWA) with assistance from Simon Molyneux (Molyneux Advisors) and Jeremy Prosser (Task Fronterra) \nHard limit of 30 attendees.  \nCost:  \nPESA Members:  $30 \nCCUSNA Members: $30 \nThis event is for PESA WA and CCUSNA members only. This is for insurance purposes. Please do not book on behalf of non-members. Please do not attend if you do not have a ticket. \nIf there are any questions\, please don’t hesitate to contact:  wa-secretary@pesa.com.au

SUMMARY:Joint PESA - SPE WA Evening Event May 2025:  CCS projects and insights from across Australia
DESCRIPTION:PESA – SPE WA invites you to Joint Evening Event.\n\nCCS projects and insights from across Australia: Thursday 15th May 2025\n\nGorgon Carbon Capture and Storage – Insights and Lessons Learned\nRobert Root (Chevron Australia) will provide an overview of Gorgon CCS including performance to date\, system optimization\, and key lessons for other CCS projects. The Gorgon Liquified Natural Gas (LNG) plant is supplied by gas from two foundation fields: Jansz which has low reservoir CO2\, and Gorgon which is relatively high in reservoir CO2 (~14%). The design of Gorgon Project included systems to extract CO2 from the reservoir gas stream feeding the LNG plant and inject it into the Dupuy Formation below Barrow Island (BWI) for permanent storage. Since 2019 CO2 has been injected into the Dupuy at globally significant rates with over 10 million tonnes injected\, however the system has been limited by the capacity to manage reservoir pressure through producing water from the Dupuy Formation and injection into the overlying Barrow Group. Activities are currently underway to increase pressure management capacity including side-tracking and re-completing existing wells\, drilling additional wells\, and installation of surface filtration facilities. \nCO₂mpartmentalising Climate Change: Perth Basin’s Role\nJulia Cass (DEMIRS) will discuss reservoir quality controls in the Perth Basin that have been evaluated to rank carbon storage targets for a CO₂ Storage Atlas being prepared by the Geological Survey of Western Australia. The key attributes for the most prospective targets include thick intervals with high net-to-gross passing cut-off criteria of shale volume below 30% and porosity greater than 10% at depths suitable for supercritical CO₂ storage. Reservoir heterogeneity is preferred as it permits greater lateral plume migration by enhancing residual gas trapping thereby boosting storage efficiency. These attributes alongside seal effectiveness determine the most suitable storage intervals. \nThe Cattamarra Coal Measures emerged as the highest-ranked storage interval of the evaluated targets. It is characterised by thick\, high net-to-gross sections with coarse-grained channel sands providing excellent injection potential. Burial and temperature control diagenesis which naturally degrades porosity and permeability with depth ultimately defining the lower limit of intervals prospective for storage. A combination of temperature modelling\, petrophysical analysis and depth mapping has been utilized to delineate the Cattamarra Coal Measures reservoir target and assess the overlying regional seal of the Cadda Formation. \n\nGlobal CCUS overview: Pivotal progress and persistent challenges\nAnne Forbes (Wood Mackensie) will discuss the highs and lows in the CCUS space across 2024. The 48 Mtpa of sanctioned project capacity was much lower than expected\, although new project capacity announcements remained at a healthy rate. Asia Pacific led in licencing\, with 90% of new awards occurring in APAC. And in Australia\, Moomba CCS\, the world’s lowest cost CCS project to date\, commenced operation. \nLooking forward\, we expect a record number of FIDs\, industry first start-ups\, and the first commercial scale CO2 ship to set sail in 2025. But at a global level we expect the rate of licensing to slow as existing work commitments are actioned. \n\nTickets on sale shortly: \n\nTicket Prices: \nMember (Early Bird): $40.00 \nNon-Member (Early Bird): $60.00 \nMember: $50.00 \nNon-Member: $70.00 \nEarly bird pricing ends Thursday (1 week prior) at 5pm (AWST).

SUMMARY:PESA WA April Technical Lunch: What you should know about borehole images but were afraid to ask…. Forty years of hard-won lessons
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 17th April.\nWhat you should know about borehole images but were afraid to ask…..  Forty years of hard-won lessons\nPresented by Lawrence Bourke (Task Fronterra Geoscience)\n\nBorehole images (BHI) have been around commercially\, for around 40 years now.  The real breakthrough was led by SLB using micro-resistivity on wireline providing cm scale\, high resolution images capable of supporting detailed sedimentological and fracture characterisation to compliment structural analysis.  A whole new field of study\, complimentary to core and seismic data was born! \nIn the early 1990s two things began in earnest:  The development of LWD tools (which would take 20 years to catch up with wireline usability) and the widespread use of Oil Based muds which were a serious setback to BHI interpretability and application\, that would take nearly 20 years to resolve with electronics innovation. \nToday\, there is a bewildering array of image tools: micro resistivity\, sonic\, density\, induction\, capacitance\, electromagnetics\, passive nuclear etc.  All the acquisition companies have their “me too” LWD and wireline offerings\, and also rebrand from time to time!.  But they are not all the same\, in terms of resolution\, bedding definition\, accuracy and application.  But the sales engineers won’t really help you decide! \nFortunately\, we have done that hard work of comparison\, applicability\, and reliability.  Based on detailed commercial studies across the globe over the last 40 years\, the conclusions are presented in a clear and concise manner for the casual BHI user. \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).

SUMMARY:PESA QLD: Lunch\, 20 March : What happened to CO2 storage in the Great Artesian Basin?  (Navigating gas water rock reactions and potential groundwater impacts) - Dr Julie Pearce
DESCRIPTION:PESA technical lunches are back for 2025! \nPESA Queensland welcomes Dr Julie Pearce to present a technical luncheon on What happened to CO2 storage in the Great Artesian Basin? (Navigating gas water rock reactions and potential groundwater impacts) \nThe Technical Lunch will be held at the Brisbane Hilton Hotel\, (Room TBC). \nFor detailed directions\, see explanation below. \nPlease note the Early Bird ticket pricing cut-off times described below. \n\n\n\nPresentation:\nWhat happened to CO2 storage in the Great Artesian Basin? (Navigating gas water rock reactions and potential groundwater impacts)\n\n\nVenue:\nHilton Hotel Brisbane\, 190 Elizabeth Street\, Brisbane QLD 4000\nRoom TBC\n(Detailed directions below)\n\n\nDate & Time:\nThursday\, 20 March 12:15 PM\n\n\n\nPresentation Abstract: \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\nTickets for the Technical Luncheon can be purchased below. \nPlease be advised of the early bird cut-off date. \nEarly bird pricing will remain available up until Friday\, 7 March 11:30 PM  after which\, standard pricing will come into effect. \nStandard ticket pricing will be available until Monday\, 17 March 12:00 PM – To avoid disappointment please register before this time. \n\n\n\n\nEarly Bird Ticket Price\nStandard Ticket Price\n\n\n\n\nMembers – $55\nNon-Members – $75\nStudent / Retired Members – $30\nMembers – $75\nNon-Members – $95\nStudent / Retired Members – $30\n\n\n\n\nLate ticket sales up to Wednesday\, 19 March 12:00PM will be available at $95 for all tickets – subject to availability.

SUMMARY:Wadjemup (Rottnest) Field Trip - Carbonate systems\, sea level change and Quokkas
DESCRIPTION:Wadjemup (Rottnest) Field Trip – Carbonate systems\, sea level change and Quokkas– by bike\nLed by Dr Moyra Wilson (University of Western Australia) \nThough some 18 km offshore at the present day\, during previous glacial lowstands Wadjemup (Rottnest Island) was joined to the mainland. Evidence of fluctuating sea-levels and environmental change is preserved both in the oral histories of the Whadjuk Noongar people but also the rocks and landforms of the island. Wadjemup offers excellent opportunity to explore classic carbonate aeolianites\, coral reef\, lacustrine and lagoonal deposits and marine features that are a conspicuous feature of the Pleistocene Tamala Limestone and associated units that outcrop over some 1000 km of WA’s coastline. \nThe trip\, led by Moyra Wilson\, will also facilitate broader discussions of approaches to palaeosea-level reconstructions\, climate change and the coastal dynamics of WA’s younger geological evolution. \nPlease note that for insurance reasons this trip is only open to members. If you are not currently a member you will need to sign up before booking. \nPrices: \nMembers:                     $100 \nStudents:                       $50 \nTickets close the Thursday prior at 5pm. \nNote: This price is for the instruction only.

SUMMARY:PESA WA February Technical Lunch: Natural Hydrogen in Western Australia
DESCRIPTION:Hosted with thanks to our Platinum sponsor SLB: \n  \n \nGold Sponsors IKON Science and DUG: \n                                              \n  \nand Silver Sponsors Delft and Qeye: \n              \n\nPESA WA invites you to our technical luncheon on Thursday 20th February.\nNatural Hydrogen in Western Australia\nPresented by Leon Normore (Geological Survey of Western Australia)\n\nThe nascent field of natural hydrogen investigations is expanding rapidly worldwide. Recent studies in Australia have documented hydrogen in natural gas samples in both sedimentary basins and cratonic settings. Study of open file data at the Geological Survey of Western Australia (GSWA) focused on historical occurrences of hydrogen primarily within the onshore sedimentary basins. Petroleum wells were the primary data source\, but natural hydrogen has also been detected in mineral exploration drillholes\, shallow gas seep drilling and water bores in Western Australia. The GSWA has investigated soil gas spot sampling and continuous soil gas measurements for natural hydrogen in the Canning and Perth Basins. Additional studies include the use of Fluid Inclusion Stratigraphy (FIS) from well cuttings and core demonstrating anomalous zones of both hydrogen and helium in petroleum wells. \nLegislation for exploration of natural hydrogen in Western Australia was passed in May 2024 by adding hydrogen as a prescribed regulated substance to the Petroleum Legislation Amendment Act 2024. Supporting regulations for natural hydrogen exploration are currently being developed in conjunction with the transport and storage of greenhouse gas regulations. \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).
