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).

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  URL:https://pesa.com.au/events/pesa-wa-october-technical-evening-three-dimensional-architecture-of-wave-dominated-detla-deposits/ LOCATION:The Globe\, 495/497 Wellington Street\, Perth\, Western Australia\, 6000\, Australia CATEGORIES:Industry,Technical Lunch,WA ATTACH;FMTTYPE=image/avif:https://pesa.com.au/wp-content/uploads/2025/08/Graphic.avif ORGANIZER;CN="PESA Western Australia":MAILTO:wa-secretary@pesa.com.au END:VEVENT BEGIN:VEVENT DTSTART;TZID=Australia/Sydney:20250909T120000 DTEND;TZID=Australia/Sydney:20250909T143000 DTSTAMP:20260605T161432 CREATED:20250825T000508Z LAST-MODIFIED:20250825T000508Z UID:10008726-1757419200-1757428200@pesa.com.au SUMMARY:PESA ACT/NSW September Technical Talk DESCRIPTION:Hot Rocks and Hydrogen : the Devil’s Brew\nNE Tasmania has a thin crust and shallow Curie Point Depth\, and is a geologically distinct terrane to the rest of Tasmania. High heat flow values and slow mid-upper crust Vp values support regional and detailed magnetotelluric surveys which indicate shallow electrical conductivity anomalies similar to those observed beneath geothermal fields in NZ and elsewhere worldwide. Devil Resources has modelled existing data to define a hot zone at economically exploitable depth. Other potential zones are identified nearby. Devil is also investigating the potential for natural hydrogen west of the Tamar\, where a set of ultramafic thrusts are identified. The Devil licences are centred on Bell Bay\, where a deep water port and manufacturing zone provide a good basis for viable development. Electricity demand in Tasmania is strong and expanding.

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.

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  URL:https://pesa.com.au/events/pesa-wa-august-technical-evening-2025/ LOCATION:Parmelia Hilton\, 14 Mill Street\, Perth\, Australia CATEGORIES:Industry,Technical Lunch,WA ATTACH;FMTTYPE=image/avif:https://pesa.com.au/wp-content/uploads/2025/07/Image_August2025_Talk.avif ORGANIZER;CN="PESA Western Australia":MAILTO:wa-secretary@pesa.com.au END:VEVENT BEGIN:VEVENT DTSTART;TZID=Australia/Sydney:20250812T120000 DTEND;TZID=Australia/Sydney:20250812T143000 DTSTAMP:20260605T161432 CREATED:20250731T231549Z LAST-MODIFIED:20250808T053853Z UID:10008716-1755000000-1755009000@pesa.com.au SUMMARY:PESA ACT/NSW August Technical Talk DESCRIPTION:About the Presentation\nEncountering Aboriginal cultural heritage is something that is unavoidable in our members’ work and the impact that it has can sometimes cause unexpected outcomes.

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.

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.

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.

The May 2025 PESA lunch will be the first public release of the main outcomes from this project. \nThe Cambrian eastern Warburton Basin underlies the bulk of the hydrocarbon-producing Permian Cooper Basin in South Australia. The Warburton\, like the Cooper Basin\, is hydrocarbon bearing with a significant catalogue of hydrocarbon shows recorded from a wide variety of lithologies and stratigraphic intervals. Therefore\, understanding the stratigraphic context of hydrocarbon occurrences is critical to unlocking this basin’s prospectivity. It is in this context that two integrated seismic-based interpretations were undertaken in this project and are the focus of PESA’s May 2025 lunch time lecture. \nThe initial seismic interpretation\, by R. Kirk\, looked at the whole eastern Warburton Basin with the results providing the stratigraphic and gross depositional environment (GDE) concepts that underpin the entire project. From this work a new stratigraphic sub-division of the Warburton Basin has been developed (Kirk et al 2025). Subsequently\, the second seismic study was undertaken (by T. Rady) building upon the seismic sequence stratigraphic framework developed by Kirk et al (2025) by combining seismic attributes\, structural and seismic facies mapping and core descriptions to develop GDE and updated reservoir distribution maps for the uppermost section\, termed ‘400-1000’. This work has provided new insights into the basin stratigraphy\, evolution and prospectivity for hydrocarbons (Rady et al 2025). \n  \n\nEvent Details:\nThursday 22nd May 2025\nThe May luncheon is a week earlier than usual due to the AEP conference during the last week of May \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\, 19th May 2025 \nAny late bookings will incur an additional $20 fee.

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.

We utilize 3D seismic\, petrological and geochemical data to reconstruct source rock deformation and hydrocarbon accumulation in the context of detachment tectonism associated with uplift of the Kaiping MCC. In the pre-MCC stage\, high-quality deep-water lacustrine source rocks of the Lower Wenchang Formation were deposited during the intense rifting. During the late Wenchang stage\, the Kaiping MCC was uplifted via a rolling-hinge process\, which caused the transformation of the original attitude and position of the source rock layers in the Lower Wenchang Formation. The distribution of the source rocks can be characterised by three distinct patterns: disconnected with antithetic dip direction (Model I)\, moderate continuous and V-shaped (Model II)\, and continuous with primitive original dip direction (Model III). These models control the dominant migration direction of hydrocarbons. Furthermore\, the extensive development of fault systems and block rotations associated with the Kaiping MCC linking source rocks to traps and influence local oil migration pathways. The breakthrough of hydrocarbon exploration in the Kaiping Sag verifies that supra- detachment basins associated with MCCs also have the potential to develop high-quality source rocks\, particularly during the rifting phase preceding the uplift of the MCC. The source rocks distribution models\, antithetic faults\, and rotating fault blocks resulting from the Kaiping MCC can serve as a reference model for evaluating source rocks and analysing hydrocarbon accumulation patterns in similar types of basins.

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.

This study includes regional petrophysics\, geomechanics\, rock physics\, seismic reprocessing and inversion in an area of sparse well and seismic data. \nAlthough numerous wells have been drilled in the Petrel Sub-basin\, their focus has been the underlying Palaeozoic petroleum system\, resulting in scant or compromised data quality in the overburden. This often limits data utility for reservoir characterization\, field appraisal and development planning for the primary Mesozoic storage targets. Seismic reprocessing and quantitative interpretation supported by a model-based rock physics workflow have been used to fill in some of the gaps. This new data has been used to interpret depositional trends of both reservoir and seal\, reservoir quality\, heterogeneity and clay content\, seal presence and thickness\, and interval velocity away from well control. Insights from this study further highlight the suitability of G-11-AP for large scale CO2 storage. \n  \n\nEvent Details:\nThursday 27ht February 2025\nLuncheon: 12 pm for a 12:30 pm start\nPlace: Ayer’s House\, 288 North Tce\, Adelaide \nThe luncheon will consist of 3 courses and a 3-hour drinks package \nBookings close 1 pm Monday\, 24th February 2025 \nAny late bookings will incur an additional $20 fee.

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.

Others synthesised state of the art in disciplines such as sedimentology and geochemistry\, building on developments from the previous decades\, like pieces of a jigsaw puzzle falling into place; these works not only led to a more innovative approach to petroleum exploration but also laid the foundations for systematic basin analysis\, play analysis\, petroleum systems analysis\, and risk analysis – approaches that would emerge as essential tools for the petroleum industry in the 1980/90s and beyond. \nWhat were these pivotal publications\, and who were their authors? How and where did these ideas and breakthroughs originate\, and how were they received by both academia and the industry? \nRhodri Johns will tell this story from a personal perspective\, offering new insights from those closer to the action. \n  \n\nEvent Details:\nThursday 12 December 2024\nLuncheon: 12 pm for a 12:30 pm start\nPlace: Ayer’s House\, 288 North Tce\, Adelaide \nThe luncheon will consist of 3 courses and a 3-hour drinks package \nBookings close 1 pm Monday\, 9th December 2024 \nAny late bookings will incur an additional $20 fee.

It seemed an appropriate invitation to accept when in July this year I realised that my passion for geology came a full circle with a trip to the Bungle Bungle Range in the Kimberley region. The magnificent beehive structures and their alternating red and yellow colouring caused the posing of the question why? The same question as a teenager I asked what causes the colour of rocks and who studies this? \n\n\nTransitioning from full time employment to “my time” employment is exciting and highly recommended if affordable and I am excited to share experiences\, lessons learned\, and yarns on all these influences and mentors that shaped my career so far. \nI strongly believe there is plenty of running room in the future demand of hydrocarbons to improve global standards of living\, while we find better ways to cut emissions and seek alternatives. \n\n  \nPESA WA Annual General Meeting\nPESA WA is seeking new committee members to support the running of the society and its active program of technical and social events throughout the year.  A range of positions are available\, with opportunities to shadow existing members to build experience and understanding of the committee. \nNominations for 2025 committee positions are required by the 6th of December\, prior to the AGM at the Annual Christmas Luncheon on the 12th of December. For further information please review role descriptions in the 2025 nomination form (link below) or reach out to the WA President (wa-president@pesa.com.au) or WA Secretary (wa-secretary@pesa.com.au) for further details. \nPESA Committee Nomination Form \n\nHosted with thanks to our Platinum sponsor SLB: \n \nGold Sponsors IKON Science and DUG: \n \n  \nand Silver Sponsors Delft Inversion and Qeye: \n              \n  \nEach lunch ticket includes networking drinks at Metro Bar afterwards.  No admittance to the drinks if you have not purchased a lunch ticket. \n\nTicket Prices: \nMember (Early Bird): $79.00 \nStudent Member (Early Bird): $49.00 \nNon-Member: $109.00 \nMember (Non-Early Bird): $89.00 \nEarly bird pricing ends Thursday (1 week prior) at 5pm (AWST).
