SUMMARY:PESA QLD: Evening Talk\, 24 September: Three-Dimensional Architecture of Wave-Dominated Delta Deposits - Dr Brian Willis
DESCRIPTION:  \nPESA Queensland welcomes Brian Willis to present a technical evening presentation on Three-Dimensional Architecture of Wave-Dominated Delta Deposits. The evening will be held at the Brisbane Port Office Hotel\, Blue Room. Extended abstract below. \nSpeaker travel and accommodation have been supported by Santos Ltd. \n\n\n\nPresentation:\nThree-Dimensional Architecture of Wave-Dominated Delta Deposits\n\n\nVenue:\nPort Office Hotel Brisbane\, 40 Edward St\, Brisbane City QLD 4000\n\n\n\nDate & Time:\nWednesday\, 24 September 6:00 PM\n\n\n\n\n  \nThree-Dimensional Architecture of Wave-Dominated Delta Deposits\nBrian Willis1\, Tao Sun2 and Bruce Ainsworth3\n1. Presenter\, Willis Geoscience\, Consultant\, Longmont\, CO\, USA; 2. Chevron Technology Center\, Research Fellow\, Houston\, TX\, USA; 3. Adjunct Professor\, University of Adelaide\, Australia. \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. \n \n  \n\n  \nTickets for the Technical Evening Talk can be purchased below. \nStandard ticket pricing will be available until Friday\, 19 September 5:30 PM – To avoid disappointment please register before this time. \n\n\n\n\nTicket Price\n\n\n\n\n\nMembers – $35\nNon-Members – $45\nStudent / Retired Members – $25\n\n\n\n\n\n

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

SUMMARY:PESA WA: 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). All ticket sales close at 5pm Friday 13 March.  No further tickets will be allocated after this time. \nPlease note that this event will be held on Tuesday 17 March at the Shoe Bar (Shop GSO7 Yagan Square\, 376 – 420 Wellington St\, Perth WA 6050).

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). All ticket sales close at 11am Monday 11 May.  No further tickets will be allocated after this time.   \nPlease note that this event will be held on Thursday 14 May at Parmelia Hilton (14 Mill Street\, Perth) and will include food and drinks. \nHosted with thanks to our Platinum Sponsor: \n \nand Gold Sponsor: \n \nand Silver Sponsors: \n \n \n \nand Bronze Sponsor: \n \n\n
