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

SUMMARY:PESA Sedimentology and Stratigraphy Interest Group (SSIG) Meeting - August 2024
DESCRIPTION:PESA Sedimentology and Stratigraphy Interest Group meeting \n30th of August\, 1 – 4pm Carlisle Core Library\n4pm Balmoral Hotel\, Victoria Park\nCores from the Middle Jurassic J20 Reservoirs of Australia’s Western Margin\nMiddle Jurassic reservoirs have helped underpin Australia’s gas export industry for decades and will for many more. This widespread thick sand dominated unit is variably named the Yarragadee Formation\, Cattamarra CM\, Legendre Formation and Plover Formation\, depending on basin. It represents a mega deltaic succession grading from fluvial to deltaic to marine and back again\, both vertically and laterally from the Perth Basin in the South and continuing to East Timor and Indonesia in the Nth. Cores have been chosen to cover the vertical and lateral variation with cores from Houtman-1 in the Perth Basin\, Perseus-2 in the Nth Carnarvon Basin\, Callaince-1 in the Browse Basin and Barrossa-3 in the Bonaparte Basin. Depofacies include fluvial channel fill\, distributary channel fill\, shore face\, interdistributary bay\, delta front\, offshore transition and open marine. Come and review the facies variations\, the diagenetic variability and the controls on production that are evident in the core. See if you can identify climatic indicators in this system as well. \nOrganisers: Rob Seggie and Darren Ferdinando \nAs is tradition\, the SSIG workshop will be followed by drinks at 4.00 pm at the Balmoral Hotel\, Victoria Park. \nPESA supplies nibbles\, but drinks are at your own expense. \nHard limit of 35 attendees and every previous SSIG meeting has been fully booked out.  \n  \nCost:  \nMember:  $10 \nStudent members:  Free \n  \nRegistrations close Thursday 29th August at 5pm. \nThis event is for members only. This is for insurance purposes. Please do not book on behalf of non-members.
