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 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 - 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 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 - 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:PESA WA November Technical Evening: Recent applications of seismic geomorphology / stratigraphy: Deep-water deposits of the Bay of Bengal and the Norwegian Sea
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\nSupported by Santos Ltd\nPESA WA invites you to our technical evening on Thursday 6th November.\nRecent applications of seismic geomorphology / stratigraphy: Deep-water deposits of the Bay of Bengal and the Norwegian Sea\nPresented by Henry Posamentier (Consultant)\n\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. \nTicket Prices:\nMember: $35.00 \nStudent Member: $10.00 \nNon-Member: $50.00 \nStudent Member pricing ends Thursday (1 week prior) at 5pm (AWST). \n

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 WA: Barry Goldstein Medal Lecture Tour February 2026 - Bruce Ainsworth
DESCRIPTION:Hosted with thanks to our Platinum sponsor: \n \nand gold sponsor: \n \nand Silver Sponsors: \n \n \n \nand Bronze Sponsors: \n \nPESA WA invites you to our technical luncheon on Thursday 19th February at The Melbourne Hotel\n“Honouring the Humble Clinoform: Towards a Reservoir Modelling Best Practice”\nPresented by Bruce Ainsworth (PESA Barry Goldstein Medal Lecture Tour 2026)\nClinoforms have fascinated Bruce since first pondering their economic significance in Shell Research Laboratories in the early 1990’s. These dipping stratal surfaces are ubiquitous in the stratigraphic record but often ignored with regard to their potential significant influence on fluid flow in the subsurface. Whether you are interested in hydrocarbon or groundwater extraction\, carbon sequestration\, or sediment hosted uranium\, you need to know if you are dealing with clinoforms. Clinoforms can have significant impacts on resource recovery and emplacement. Ignoring them or simply not recognising them can have profound (usually) negative impacts on project value. Key to making clinoforms your best friend are three steps; 1) recognition\, 2) uncertainty management\, and 3) targetted modelling. This talk will guide the clinoform user through these steps and suggest a reservoir modelling best practice for honouring the humble clinoform. \nTicket Prices:\nConcession Member [Retired or Hardship]: $69.00 \nStudent Member: $30.00 \nNon-Member: $109.00 \nMember: $89.00 \nEarly bird\, Concession\, and Student pricing ends 5pm on Thursday February 5th (2 weeks prior). All ticket sales close at noon on Monday February 16th (3 days prior). No further tickets will be allocated after this time due to venue restrictions.  Please note that for tickets purchased after 11 February 2026\, dietary requirements may not be able to be catered for\, however we will do our best. \nPlease note that this event includes lunch (main meal and dessert)\, soft drinks and juice\, tea and coffee.  There will be a cash bar available prior to the presentation. \nPlease also note that the venue for this event will be held at The Melbourne Hotel (33 Milligan Street\, Perth).

SUMMARY:PESA WA: Stretching or Flexing - A Review of the Triassic from the Northern Carnarvon and Roebuck Basins
DESCRIPTION:Hosted with thanks to our Platinum Sponsor: \n \nand Gold Sponsor: \n \nand Silver Sponsors: \n \n \n \nand Bronze Sponsor: \n \n\nPESA WA invites you to our technical evening event on Tuesday 17 March at the Shoe Bar:\nStretching or Flexing – A Review of the Triassic from the Northern Carnarvon and Roebuck Basins\nPresented by Alex Maftei (Curtin University)\nIn this technical session\, Alex Maftei will present the results of his giant interpretation effort\, which includes Triassic formation tops for 442 wells within a sequence stratigraphic framework\, at least four key Triassic horizons\, and more than 2300 faults interpreted in an extremely large seismic dataset. This study also incorporates basin-wide structural and isochron maps of the main Triassic sequences\, depth conversion\, and a velocity model that resulted in isopach maps\, establishing the enormous thickness of the Triassic (up to 16 km). Forty wells were backstripped\, and the total and tectonic subsidence were determined. The backstripped thickness at the beginning of the Jurassic was used to evaluate the flexural component of the subsidence (46–73% of the total subsidence). The elastic lithosphere thickness that best fits the data is between 20 and 30 km. The presentation will include notes on the wider development of Triassic volcanism\, stratigraphic observations on the Triassic from the western Exmouth Plateau\, such as a prograding deltaic system and incised valleys at the Ladinian-Carnian boundary\, multi-erosional surfaces\, and canyons in the Norian\, and the earlier development of reefs in the Late Norian. \nTicket Prices: \nMember (Early Bird until 5pm Tuesday 10 March): $40.00 \nMember: $50.00 \nStudent Member: $20.00 \nNon-Member: $60.00 \nEarly bird pricing ends Tuesday 10 March (1 week prior) at 5pm (AWST).

SUMMARY:Joint PESA - SPE WA Evening Event: 14 May 2026
DESCRIPTION:Joint PESA and SPE Evening Event\nThursday 14 May 2026 (5pm-8pm)\n\n\nThe Bonaparte CCS Project – Mathieu Muller & Paul Froydenlund (INPEX)\nAs part of its Vision 2035\, INPEX is progressing carbon capture and storage (CCS) initiatives to support lower-carbon energy solutions. This presentation will provide an overview of INPEX’s global CCS strategy. It will also highlight the company’s efforts to decarbonise its upstream operations\, including proposed development of the Bonaparte CCS Project – an initiative aimed at providing safe\, permanent offshore CO₂ storage to support emissions reduction. \nThe Integration of Core and FMI Borehole Image Data in Understanding Reservoir Heterogeneity for CCS Studies: West Peron-1 and West Peron-2\, Bonaparte Basin – Fiona Burns (Task Fronterra)\nCore and FMI borehole image data from wells West Peron-1 and West Peron -2 provide a remarkable dataset for gaining insights into reservoir architecture and heterogeneity in the Jurassic to Cretaceous successions of the Bonaparte Basin. Such information is critical in the assessment of suitable sites for the long-term storage of CO2 in the Bonaparte Basin in terms of injectivity potential and movement of the CO2 plume (porosity\, permeability\, lateral and vertical heterogeneity). \nThis talk will focus on the Elang and Frigate formations\, which comprise exceptionally thick successions of deltaic and shallow marine sediments with highly complex depositional histories. The high-resolution FMI data\, calibrated with core\, provides precise information on lithofacies\, depositional environments and sediment-dispersal trends. The FMI data also assists in the interpretation of bedform architecture and channel-fill style. Integrated core and FMI data aids evaluation of the key controls on deposition i.e. river-\, wave & and storm\, – and tidal influences. This talk will summarise the evolution of both the Elang and Frigate formations\, highlighting the dominant controls on deposition of these formations. This approach also provides an invaluable framework in which small-scale features that can cause baffles/barriers to fluid flow can be assessed e.g. tidal clay drapes\, fluid-mud deposits\, types and degrees of bioturbation\, the presence of cemented layers and concretions. \n\nGeomechanical Modelling of Hydrogen Storage at the CO2CRC Otway International Test Centre – Ratih Puspitasari (SLB) with an introduction by Dr Eric Tenthorey (Geoscience Australia)\nAustralia’s emerging hydrogen economy depends on the ability to safely store large quantities of hydrogen underground. As part of the national Exploring for the Future program\, this study assesses the suitability of depleted gas fields for hydrogen storage\, using the CO2CRC Otway International Test Centre as a representative site. \nWith natural gas and CO₂ storage far more extensively characterised\, these systems provide essential reference points for understanding subsurface hydrogen storage behaviour. However\, hydrogen’s distinct density\, viscosity\, compressibility\, and thermal properties mean that established injection and storage practices from these gases cannot be assumed to apply directly. To investigate these differences\, this study presents the first like‑for‑like comparison of hydrogen\, methane\, and carbon dioxide behaviour under identical reservoir conditions. A fully coupled reservoir–geomechanics–thermal model was developed for this purpose\, incorporating high‑resolution wellbore grids to quantify pressure\, temperature\, and stress evolution. \nResults show that hydrogen injection generates significantly lower thermal perturbations than methane or CO₂\, reducing the likelihood of thermally induced fault reactivation and wellbore fracturing. Simulations also demonstrate that moderated injection rates further minimise thermal and pressure impacts\, providing additional operational safeguards. The study underscores the importance of integrating flow modelling with geomechanical risk assessment and highlights how dynamic injection control strategies can enhance the safety and efficiency of future hydrogen storage projects. \n\n  \n\nTicket Prices: \nMember (Early Bird): $65.00 \nMember (Non-Early Bird): $75.00 \nCCUSNA Members (Early Bird): $65.00 \nCCUSNA Members (Non-Early Bird): $75.00 \nNon-Member: $90.00 \nEarly bird pricing ends Wednesday 6 May at 5pm (AWST).

SUMMARY:PESA WA: Introduction to Play Mapping
DESCRIPTION:PESA WA invites you to a two-day course on Wednesday 10 June and Thursday 11 June at the Shoe Bar\, Yagan Square\, Perth\nIntroduction to Play Mapping\nPresented by: Dr Darren Ferdinando (Basin Science)\n\nObjectives\nThis course is designed to introduce geological play mapping for oil and gas exploration. It is aimed at geoscientists who are interested in applying the concepts of hydrocarbon play mapping to identify areas of high and low prospectivity in terms of the key play elements –\nreservoir\, seal\, trap and charge and using these to identify hydrocarbon potential across scales from permit to basin-wide assessments for quick-screening of new ventures opportunities through to detailed play assessments of core areas. Over two days participants will be shown: \n\nMethodologies for breaking a stratigraphic succession into a series of meaningful and manageable plays with emphasis on using sequence stratigraphic concepts\nWhat comprises the key play elements in a play and how to characterise them\nPost-Drill Assessment of petroleum wells for play mapping\nMapping out Gross Depositional Environments across a play\nVarious styles of play mapping from simple ‘Traffic Light’ mapping through to detailed split risk maps and the scenarios in which they are used\nIntegration of play maps with Prospects and Leads and how to apply various risking schemes (e.g. 4-factor risking\, 5-factor risking etc) to the play mapping\nBasin-wide assessment of multiple plays\nDiscussion of examples of play mapping across several onshore and offshore Australian Basins and the benefits and pitfalls of a variety of play mapping methodologies\n\nContent\nThe process of play mapping incorporates assimilating data from petroleum wells\, seismic data\, sequence stratigraphy\, remoting sensing (magnetic and gravity) data and other sources and combining this data into a spatially meaningful and consistent set of maps that highlight areas of high\, medium and low prospectivity as an aid for exploration. Play mapping can be used in a range of ways from screening large areas for new ventures or gazettal assessments\, determination of areas with lower potential to relinquish in a permit renewal\, or even to identify frontier areas with the high potential to acquire new data across. Participants will work through the core concepts in play mapping through presentations and a series of interactive activities and hands-on exercises in play mapping using data from Australian basins to create play and gross depositional environment maps. \n\nTicket Prices: \nMembers: $750.00 \nNon-Members: $1000 \nStudents: $200.00 (NB – one place only available) \nPlease note that this event will be held on Wednesday and Thursday 10 & 11 June 2026 at The Shoe Bar (Yagan Square\, Perth). \n

SUMMARY:PESA WA: June Technical Luncheon: Dr Peter Moore - Australian Geoscience Council (AGC) National Geoscience Champion
DESCRIPTION:PESA WA invites you to our June Technical Luncheon on Thursday 25 June at The Melbourne Hotel:\n“Petroleum Geoscience and the Energy Transition: A Personal Historical Perspective and Predictions for the Future”\nPresented by Dr Peter Moore (Adjunct Professor at Curtin University)\n\nAn historical perspective on important advances that Dr Peter Moore has been witness to\, and continuation of the story into the future around the emergence of non-fossil-fuel energy sources and the likely ongoing roles of geoscientists. \nThe petroleum industry was technologically advanced by the mid 1900s\, but a number of developments over the last half century stand out in the areas of seismic\, sequence stratigraphy\, assessment technologies\, deepwater plays\, drilling\, offshore developments\, CSG and shale\, which will be discussed\, including from a personal perspective. These developments have served to maintain the competitiveness of the petroleum industry and have satisfied an increasing demand over time. \nHowever\, a key question for the industry is its future role in the evolving energy transition. Analysis is difficult because there are multiple competing narratives and strong vested interests. \nToday we sit at a pivot point\, with a growing divergence of possible energy futures\, depending on how the world balances economic growth\, energy poverty\, geopolitics\, and great power competition against emissions reduction\, fossil fuel elimination and climate change concerns. \nIn the decade since the Paris agreement and despite significant progress\, the 1.5oC goal is lost and fossil fuel’s contribution to energy consumption remains at 80%. \nWhile both sides (fossil fuel supporters and renewable proponents) argue their case\, the next 15 years at least is becoming clearer – a US/China energy and manufacturing divide\, huge growth of renewables but matched by overall energy growth\, the emergence of nuclear\, and the persistence of petroleum\, especially gas. \nDespite trillions of dollars spent on the energy transition\, we have underestimated the difficulty in speedily transitioning the world’s energy and industrial infrastructure\, and have underestimated global growth\, including overall energy consumption. This can be seen by comparing predictions and model outcomes published over the last decade. \nFor today’s petroleum geoscientists\, technology and jobs will continue to evolve while new areas are likely to include advanced geothermal\, CCS\, and potentially natural hydrogen. As fields decline and new developments and discoveries become smaller\, more effort and technology is required from petroleum companies and individuals to deliver the energy the world still demands. \n\nTicket Prices: \nEarly Bird Member (Until 5pm Thursday 18 June): $69.00 \nMember (Friday 19 June – Monday 22 June): $79.00 \nStudent Member (Until Monday 22 June): $20.00 \nConcession Member [Retired or Hardship] (Until Monday 22 June): $59.00 \nNon-Member (Until Monday 22 June): $89.00 \nEarly bird pricing ends Thursday 18 June at 5pm (AWST). All ticket sales close at 5pm Monday 22 June.  No further tickets will be allocated after this time. \nPlease note that this event will be held on Thursday 25 June at The Melbourne Hotel (33 Milligan Street\, Perth). \nPlease note that this event includes lunch (main meal and dessert)\, soft drinks and juice\, tea and coffee.  There will be a cash bar available. \nHosted with thanks to our Platinum Sponsor: \n \nand Gold Sponsor: \n \nand Silver Sponsors: \n \n \n \nand Bronze Sponsor:

SUMMARY:PESA WA: Core Values Session #2
DESCRIPTION:PESA WA is excited to invite you to our second Core Values Session for 2026 on Friday 26 June at the Perth Core Library:\nHarvey Field Cores\nPresented by Cedric Griffiths (StrataMod Pty Ltd)\n\nThe cores will be used to re-examine the assumptions behind the CSIRO 2011/12 Sedsim forward stratigraphic model of Permian/Early Triassic sediment depositional environment which was run prior to obtaining the Harvey-1 well results. \nPrior to the drilling of Harvey-1 Schlumberger had developed a depositional concept model that assumed most of the sediment being transported westwards from the Darling Scarp in the form of alluvial fans. \nThe Sedsim model had most of the sediment being provided by a large river system from the south\, sourced from Antarctic mountain sources prior to break-up\, with minor input from the eastern fault block after “Tectonic and Stratigraphic History of the Perth Basin\, Norvick\, M.S. GA 2004”. \nChanges in palynology\, sedimentation style\, ichnofabric data\, and trace-fossils in wells from south to north and east to west will be discussed and at the session the interactive Sedsim forward model results that exhibit the proposed deposition system will be run. \n\n\nTicket Prices: \nMembers: $10.00 \nNon-Members: $20.00 \nPlease note that this event will be held on Friday 26 June 2026 at The Perth Core Library (37 Harris Street\, Carlisle). Participants are welcome to bring their own lunch. \nParticipants are invited to the Balmoral Hotel (901 Albany Highway\, Victoria Park) afterwards to continue discussions. Nibbles will be provided\, and drinks will be available at the bar at your own cost.

SUMMARY:PESA WA: Alice Springs Field Trip and Core Viewing
DESCRIPTION:PESA WA ALICE SPRINGS FIELD TRIP\nPESA WA is hosting a field trip to Alice Springs in September 2026.  This is a fantastic opportunity to explore the region\, engage directly with field activities\, and deepen your understanding of the area’s geological context. \nStarting in Alice Springs\, the field trip includes three nights of 4-star accommodation\, with breakfast and lunch provided\, along with transport to and from the field. Expert guidance and commentary will be provided by Peter Haines with contributions from Fiona Burns and Simon Lang. The itinerary covers four days of Amadeus Basin geology\, split evenly between two half days viewing cores and two full days in the field. \nDuring the core workshops\, Fiona Burns (Task Fronterra) will lead participants through the Tent Hill-1 core. This well provides a near-complete section through the Lower to Middle Ordovician stratigraphy\, including the Pacoota Sandstone and overlying units. The Pacoota interval is represented by sub-units P3 to P1\, and recent work suggests deposition in a high-energy\, wave- and storm-dominated shoreface to shelf environment\, with a clear influence from nearby river systems. Simon Lang (GeoSed Consulting) will complement this by guiding the group through cores from the Mereenie Field\, including the P4 sub-unit of the Pacoota Sandstone\, offering a broader view of the full stratigraphic succession. \nIn the field\, Peter Haines (DMPE) will lead the group through the Ellery Creek section\, located approximately 90 km west of Alice Springs. This outcrop provides an exceptional\, near-continuous record of northern Amadeus Basin stratigraphy from the Tonian through to the Devonian. The field component will focus on the Larapinta Group\, comprising the Pacoota Sandstone\, Horn Valley Siltstone\, and Stairway Sandstone\, which represent the primary reservoir and source intervals for key regional accumulations such as the Palm Valley gas field\, Mereenie oil and gas field\, and the Surprise oil field. Participants can expect to see well-exposed sedimentary facies\, trace fossils\, and clear expressions of basin evolution\, with a possible extension into Devonian units depending on access conditions. \nBy combining detailed core analysis with regionally significant outcrop observations\, the trip is designed to provide a comprehensive understanding of the stratigraphy and to highlight how depositional environments and systems have evolved. \nThere will also be the opportunity to hunt for fossils\, including trilobites\, within the Horn Valley Siltstone. \nFieldtrip Leader: Peter Haines. \nContributors: Fiona Burns\, Simon Lang\, Charlie Verdel. \n \nItinerary: \nDay 1: PM: Core Store (0.5 day): Tent Hill-1 Pacoota and Stairway sandstone cores led by Fiona Burns. \nDay 2: Field Day: Ellery Creek\, Pacoota Sandstone section (shallow marine/deltaic) led by Peter Haines. \nDay 3: Field Day: Ellery Creek section (revisited) and other outcrops (stromatolites\, Dalmatian Rock) by Peter Haines and Charlie Verdel. \nDay 4: AM: Core Store (0.5 day): Mereenie Field core led by Simon Lang \n  \nCost: \n\nAttendance is open only to PESA members\, including interstate and international members.  Non-members must join PESA to attend.\n$1500.00 per person (includes accommodation\, transport to field areas\, breakfast\, lunch and digital field guide).\n\nPlease note that flights are not included in the above\, and places are limited.

SUMMARY:PESA WA: Expression of Interest Alice Springs Fieldtrip
DESCRIPTION:PESA WA are planning a field trip to Alice Springs in September 2026.  PESA WA are currently seeking expressions of interest from those who would like to join to see if this is a viable trip. This is a fantastic opportunity to explore the region\, engage directly with field activities\, and deepen your understanding of the area’s geological context.  Attendance will be open only to PESA members\, including interstate and international members.  Non-members are encouraged to join PESA to attend. \nDescription: \nThis fieldtrip is designed for geoscientists and reservoir engineers who primarily focus on deltaic and shallow marine successions\, especially those involved in building or updating geomodels. Whether your task involves a simple facies analysis and well correlation across shallow marine and marginal marine systems\, or input of fluvial channel dimensions into a geomodel\, this fieldtrip will benefit you in several ways. \nThe Ordovician Larapinta Group\, Amadeus Basin\, Northern Territory consists of a succession of mostly shallow marine\, mixed clastic and carbonate strata deposited in the epeiric Larapintine Sea of northern peri-Gondwana. The Pacoota Sandstone is a thick (up to 850 m) deposit of siliciclastic rocks straddling the Cambrian-Ordovician boundary in the Amadeus Basin of central Australia. It is a significant hydrocarbon reservoir (e.g. Meernie Field\, Palm Valley\, Tent Hill-1). It contains four stratigraphic sequences separated by datable events\, described by P Haines. These sequences can be recognised and correlated widely in the subsurface. \nThe Stairway Sandstone is a succession of Middle Ordovician siliciclastic sedimentary rocks\, composed of shallow marine sandstones and mudstones\, with calcareous units also common. The thickness of the formation is highly variable\, ranging from 30 m on the shallower southern margin of the basin to 560 m on the northern margin. \nWe will also have the opportunity to hunt for fossils\, including trilobites\, within the Horn Valley Siltstone. \nFieldtrip Leader: Peter Haines. \nContributors: Fiona Burns\, Simon Lang\, Charlie Verdel. \n \nProposed Itinerary: \nDay 1: Fly to Alice Springs. Core Store (0.5 day): Tent Hill-1 Pacoota & Stairway Sst. cores by Fiona Burns. \nDay 2: Ellery Creek\, Pacoota Sst. section (Shallow marine/deltaic) by P. Haines. \nDay 3: Ellery Creek section (revisited) & other outcrops (stromatolites\, Dalmatian Rock) (by P. Haines and Charlie Verdel. \nDay 4: Meernie Field core (0.5 day) by S Lang. Fly to Perth. \nAnticipated approximate costs: \n\n$1000.00 per person (includes accommodation\, transport to field areas\, breakfast\, lunch and field guide).\nCosts without accommodation and breakfast are anticipated to be approximately $300.00 per person.\n\nPlease note that flights are not included in the above.
