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

Once registered with the webinar software you will receive a reminder e-mail 1 hour beforehand. \nBurial diagenesis and the case of the giant Perla field in the Gulf of Venezuela Basin\nPresented by Dr Fernando Valencia Fermin  \nAbstract \n\nDiagenesis comprise all the physical\, chemical\, and biological modifications underwent by a sediment\, after its initial deposition\, during and after lithification but before reaching pressures and temperatures proper of metamorphism. Burial diagenesis\, in particular\, refers to the diagenetic modifications occurred due to the influence of burial processes in the mesogenetic environment. The study of diagenesis is important in both siliciclastic and carbonate reservoirs; however\, they are key in the latter since they are more chemically reactive. The Perla Limestone\, an Oligo-Miocene carbonate reservoir located in the Gulf of Venezuela Basin\, considered the largest gas field in Latin America (>17 Tscf of gas in place)\, shows a complex porosity system marked by a strong diagenetic control. Despite comprehensive depositional facies modelling carried out in this reservoir\, inconsistencies remained when distributing petrophysical properties with depositional facies. Specifically\, in areas strongly affected by diagenetic processes since they constitute a complex variable to reproduce in a predictive reservoir quality-model. In order to understand the impact of diagenesis in the Perla Limestone\, and its distribution along the carbonate succession; a detailed petrographic\, mineralogical and chemical analysis on well-cores was performed. As a result\, several diagenetic processes that created and destroyed porosity and permeability were identified and grouped chronologically in function of the evolution of the diagenetic environment. Within these processes\, an important burial dissolution process\, likely linked to the ascent of CO2-rich fluids mediated by basement-root faults\, fractures\, and stylolites allowed the development of pervasive secondary porosity in the vicinity of the major discontinuity surfaces. On the other hand\, blocky-calcite cementation in the near surface to shallow burial environment\, and the progressive mechanical compaction in the burial realm\, were the main responsible for reservoir quality destruction.

SUMMARY:PESA SA : Meandering Murray Field Trip & Fluvial Stratigraphy Workshop
DESCRIPTION:PESA SA : Meandering Murray Field Trip & Fluvial Stratigraphy Workshop\nMagnificent Meandering Murray field trip: a modern-day fluvial system analogue\nSep. 28th and 29th 2025\nBrian Willis (ex Chevron ) & Andrew McKerron (Beach Energy)\n  \nJoin PESA SA/NT for an Exclusive Distinguished Lecturer Event Featuring Brian Willis \nPESA SA/NT is proud to host Brian Willis\, renowned fluvial sedimentologist and stratigrapher with decades of experience at Chevron and BP\, as part of our Distinguished Lecturer Tour. This PESA Distinguished Lecture is made possible with the generous support of Santos Ltd. \n  \nThis exciting two-day workshop offers a unique blend of field and classroom learning: \n  \n\nDay 1: Field Excursion – Sunday\, 28 September Explore the stunning landscapes of the Murray River on a guided geological field trip led by Brian Willis and Andrew McKerron\n\n          Ticket Price: Free to attend | Logistics (Self organized) meeting point will be advised closer to the date \n  \n\nDay 2: Fluvial Reservoir Heterogeneity Characterization Workshop – Monday\, 29 September \n\n         Ticket Price: $250 per participant | Location: Ayers House \nWhether you’re a student\, professional\, or enthusiast\, this is a rare opportunity to learn directly from one of the industry’s leading experts. \nLimited spots available – register now! \n  \nWorkshop Details:\nFluvial Systems – From River to Reservoir\nTraditional characterization of fluvial reservoirs focuses on relating vertical facies patterns observed in core samples to a static aerial view of an analogue river. Such comparisons fall short of generating precise predictions of the distribution of reservoir heterogeneities that can impact subsurface fluid flow and reservoir development behavior. Heterogeneity patterns within fluvial deposits are emergent structures (i.e.\, in systems analysis\, “emergent structures” are patterns that arise from the collective actions of many individual parts and behaviors and have properties that the parts themselves do not have). In fluvial deposits\, these patterns are formed by shifts in deposition and erosion during river floods\, dynamic changes in grain sorting along a river channel during lateral migration and cutoff within a channel belt\, and the stacking of channel belts as the floodplain aggrades. This course aims to build on traditional fluvial facies models to develop a more dynamic understanding of how a hierarchy of depositional processes defines heterogeneity patterns within fluvial reservoirs. \n• Discuss terminology and concepts to define the hierarchy of processes and deposits that control reservoir-heterogeneity 3D patterns and scaling. \n• Examine process-based\, numerical\, river depositional models to better understand the emergence of heterogeneities within evolving channel belts. \n• Catalogue 3D facies patterns developed within a range of river systems as a template for defining reservoir heterogeneity. \nLectures will introduce the hierarchical organization of fluvial deposits and discuss models for the development of heterogeneities within fluvial channel belts. The focus is on considering how dynamic changes preserve 3D facies patterns and understanding how these facies patterns vary between a wide range of fluvial systems. Well log interpretation and correlation exercises will demonstrate subsurface applications. The workshop is structured to challenge experienced practitioners to rethink standard practices\, while remaining general enough to benefit geologists with little experience in fluvial systems\, as well as reservoir modelers and engineers\, with a broad overview of potential subsurface variation patterns. \n  \nWorkshop Timing: \n9:30 am-5:00 pm \n  \nBrian Willis will be giving an evening talk at 5:30 pm. The talk is free for workshop attendees\, but registration is required.

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.

SUMMARY:2025 PESA WEBINAR SERIES: 2024 Development and Production Review (Martin Wilkes)
DESCRIPTION:Kindly supported by Rock Flow dynamics  \n  \nThis live webinar will take place at: \n11am              – Perth\n12.30pm       – Darwin\, Adelaide\n1pm                – Brisbane\, Canberra\, Hobart\, Melbourne\, Sydney \nUse the calendar link on this page to add this event in to your own calendar at the correct local time for your location. \nTickets are free for members (please log in to see this) and $10 for non members. \nPlease buy your tickets and immediately follow the link in the ticket e-mail (not the calendar invite or this webpage\, which is just generic and not event specific) to set up your registration with the webinar software well in advance of the time of the talk. Once registered with the webinar software you will receive a reminder e-mail 1 hour beforehand. \n2024 Development and Production Review\nPresented by Martin Wilkes (RISC Managing Director) \nAbstract \n\nGeopolitical uncertainty continued in 2024 with continuation of the war in Ukraine\, Israeli actions in the Gaza strip\, tension between China and several neighbouring countries\, and the impending election in the United States of America. Despite this\, global inflationary pressures continued to fall during the year\, although they remained higher than pre-pandemic levels. In Australia\, activism around climate change issues continued to impact project developments and sentiment in the industry remained somewhat subdued. The PESA 2024 Development and Production Review looks back at the oil and gas development and production activities in Australia in 2024 and tries to provide some sense of what happened\, and what that means for the industry looking forward. Liquefied natural gas (LNG) production in Australia recorded (unexpectedly) a new record high\, although several projects are now facing declining production. Santos won a significant court case in January 2024 on the Barossa project\, enabling it to resume construction activity on the main export pipeline to Darwin\, which had been suspended for approximately 2 months. The east coast domestic market continued to have major concerns about gas supply and one of the three gas plants at Longford was shutdown reducing supply and processing capacity significantly. Gas supply remains a critical issue in the Northern Territory.

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.

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

SUMMARY:PESA SA/NT July Luncheon
DESCRIPTION:PESA SA/NT July Luncheon\nNew Geological Studies Leading to 2025 Acreage Release in the Polda and Otway Basins\, SA\nPaul Strong and Sharon Tiainen \n(Energy Resources\, Geological Survey of SA\, Department for Energy and Mining)\nThe Polda Basin is a 10\,000 km2 Neoproterozoic to Jurassic basin covering the central western portion of the Eyre Peninsula of South Australia and extends westwards into the Great Australian Bight. The basin is only lightly explored\, with the last significant hydrocarbon exploration occurring in the offshore Polda Basin in the late 1970s/early 1980s\, with no reported hydrocarbon shows except for a relatively minor gas show of 40 ppm methane in Mercury 1. However\, source rock studies in the Jurassic section indicate the presence of immature\, relatively high TOC and excellent generative potential for both oil and gas from carbonaceous claystone and coal. Recent work by the GSSA (Tiainen\, 2025) indicates the presence of a potential source rock from the underlying Neoproterozoic Kilroo Formation\, with oil staining identified in the permeable reservoir intervals in the Polda Formation in the onshore mineral drillhole Kilroo 1A. In addition\, recent work conducted at the University of Adelaide suggests that there may be potential for a natural hydrogen accumulation within the onshore Polda Basin (Rumi Daruso 2023\, shown in Margiono et al. 2024). \nFollowing a recent acreage relinquishment\, one new Regulated Substances Exploration Licence (RSEL) in the Polda Basin is being offered as acreage release block PO2025 RSEL-A by the South Australian Government for competitive work program bidding. \nThe Otway Basin is one of the best known and most actively explored of the series of Mesozoic rift basins that span the southern coastline of Australia\, formed following rifting between the Antarctic and Australian plates. Over the last 2 years DEM has conducted studies over most of the onshore Otway Basin in South Australia\, with results suggesting that significant hydrocarbons have been generated and expelled in a number of structural troughs in the region\, and that suitable reservoir fairways and new play types are now better defined than previously. \nFollowing a recent acreage relinquishment\, five new regulated substances exploration licences (RSELs)\, three gas storage exploration licences (GSELs) and one new geothermal exploration licence (GEL) in the Otway Basin are being offered by the South Australian Government based on work program bidding. A key motivation for the acreage release is the looming shortfall in energy supply in the southeast Australian market. The South Australian onshore Otway Basin is in a strategic location for natural gas exploration and gas storage. \n  \n  \n\nEvent Details:\nThursday 31st July 2025\nLuncheon: 12 pm for a 12:30 pm start\nPlace: Ayer’s House\, 288 North Tce\, Adelaide \nThe luncheon will consist of 2 courses and drinks \nBookings close 5 pm Monday\, 28th July 2025 \nAny late bookings will incur an additional $20 fee. Strictly no walk-ins.

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

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

SUMMARY:PESA SA/NT June Luncheon
DESCRIPTION:PESA SA/NT June Luncheon\nThe impact of triggered earthquakes of the Basel geothermal project 2006 on Engineered Geothermal Systems\nMarkus Häring (Consultant)\nThe triggered earthquake of M 3.4 with subsequent events of M >2 was a turning point in the perception of induced seismicity caused by intentional pressure changes in the subsurface. The events followed a massive hydraulic stimulation into granitic basement at 5 km depth below the city of Basel. \nThe geothermal project attracted worldwide attention\, not only because the seismicity was felt throughout the city\, but also because\, for the first time\, induced seismicity was recorded in detail by a scientifically supported monitoring system. \nSince then\, microseismic monitoring systems have been greatly improved and can now be used in all underground operations where pressure changes occur\, such as oil and gas production\, fraccing\, CCS and EGS. \n  \n  \n\nEvent Details:\nThursday 26th June 2025\nLuncheon: 12 pm for a 12:30 pm start\nPlace: Ayer’s House\, 288 North Tce\, Adelaide \nThe luncheon will consist of 2 courses and drinks \nBookings close 5 pm Monday\, 23rd June 2025 \nAny late bookings will incur an additional $20 fee.

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