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 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: 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.
