PESA SA/NT May Luncheon
2025-05-22 12:00 - 14:00 (Australia/Adelaide) | Ayers House – Ballroom, 288 North Terrace, Adelaide, South Australia, 5000
PESA SA/NT May Luncheon
Prospectivity of the Daralingie Shelf area of the Warburton Basin, SA
Tim Rady (Geomorph Energy) and Rob Kirk (Consultant)
Abstract:
To further highlight the prospectivity of the Warburton Basin, the South Australian Department for Energy and Mining (SADEM) has undertaken a whole of basin project integrating regional seismic interpretations (using the 2D Cube), previous geological understanding, well and standardized core interpretations. The May 2025 PESA lunch will be the first public release of the main outcomes from this project.
The 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.
The 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).

Event Details:
Thursday 22nd May 2025
The May luncheon is a week earlier than usual due to the AEP conference during the last week of May
Luncheon: 12 pm for a 12:30 pm start
Place: Ayer’s House, 288 North Tce, Adelaide
The luncheon will consist of 2 courses and drinks
Bookings close 5 pm Monday, 19th May 2025

Joint PESA - SPE WA Evening Event May 2025: CCS projects and insights from across Australia
2025-05-15 16:45 - 20:00 (Australia/Perth) | Parmelia Hilton, 14 Mill Street, Perth, Australia
PESA – SPE WA invites you to Joint Evening Event.

CCS projects and insights from across Australia: Thursday 15th May 2025

Gorgon Carbon Capture and Storage – Insights and Lessons Learned
Robert Root (Chevron Australia) will provide an overview of Gorgon CCS including performance to date, system optimization, and key lessons for other CCS projects. 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.
CO₂mpartmentalising Climate Change: Perth Basin’s Role
Julia 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.
The 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.

Global CCUS overview: Pivotal progress and persistent challenges
Anne 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. And in Australia, Moomba CCS, the world’s lowest cost CCS project to date, commenced operation.
Looking forward, we expect a record number of FIDs, industry first start-ups, and the first commercial scale CO2 ship to set sail in 2025. But at a global level we expect the rate of licensing to slow as existing work commitments are actioned.

How lightweight seismic technology can change 3D seismic design and execution: A high channel count case study from Taranaki, NZ

Venue:
Port Office Hotel, cnr Edward & Margaret Sts, Brisbane
Blue Room (Entry off Margaret St)

Date & Time:
Thursday, 15 May 12:15 PM

Presentation Abstract:
3D seismic surveying in New Zealand’s diverse landscapes presents unique challenges and opportunities. Three moderately sized (in comparison to Australian petroleum seismic) 3D seismic surveys were acquired onshore Taranaki, New Zealand in 2021-2022 utilising very high live channel counts ranging from 34,000 to 80,000.
This talk presents the benefits recognised from the use of dense receiver sampling and large active patch sizes for conducting high-resolution seismic acquisition in an operationally and geologically challenging environment. The rugged hills, dense forests, extensive waterways, and complex landowner environments encountered in the Taranaki region demand specialized survey design, acquisition technology and workflows to ensure accurate data collection while minimizing environmental and social impact.
Modern lightweight nodal receivers facilitated a rethink of how seismic had been acquired in New Zealand and could change nearly all aspects of the planning, execution, and project costs.

Tickets for the Technical Luncheon can be purchased below.
Final numbers to venue required by COB Thursday, 5 May – To avoid disappointment please register before that date and time.

Where Comes the Gas From, Where Does it Go? Southern Denison Trough CO2 Storage Possibilities from a Geological Perspective
Presented by Alison Troup (University of Queensland)
Abstract

The southern Denison Trough contains several depleted conventional gas fields, mostly reservoired in the Aldebaran Sandstone with secondary reservoirs in sandstones of the upper Reids Dome beds. These gas fields are naturally high in CO2 and may present a good opportunity from a geological perspective for CO2 storage. In support of this an updated interpretation of the depositional environment at Merivale, Westgrove, Yellowbank and Punchbowl Gully has been developed to examine changes in depositional environment along the Aldebaran Sandstone paleocoastline. Comparison of the production history of Merivale to the variability in the depositional environment shows that there is strong contribution from the depositional environment to production behaviour.
Sandstones and coal seams in the upper Reids Dome beds may present a secondary target to depleted gas field storage in the southern Denison Trough. Gas distribution in the Reids Dome beds coals shows that the Hutton-Wallumbillla Fault may be a migration pathway for magmatic CO2 into the unit. High CO2 concentrations and saturations within these coals demonstrate a natural analogue for storage within this system. The stratigraphic placement of these coal seams has been improved through the use of stable carbon isotope analysis.

What you should know about borehole images but were afraid to ask….. Forty years of hard-won lessons
Presented by Lawrence Bourke (Task Fronterra Geoscience)

Borehole images (BHI) have been around commercially, for around 40 years now. The real breakthrough was led by SLB using micro-resistivity on wireline providing cm scale, high resolution images capable of supporting detailed sedimentological and fracture characterisation to compliment structural analysis. A whole new field of study, complimentary to core and seismic data was born!
In the early 1990s two things began in earnest: The development of LWD tools (which would take 20 years to catch up with wireline usability) and the widespread use of Oil Based muds which were a serious setback to BHI interpretability and application, that would take nearly 20 years to resolve with electronics innovation.
Today, there is a bewildering array of image tools: micro resistivity, sonic, density, induction, capacitance, electromagnetics, passive nuclear etc. All the acquisition companies have their “me too” LWD and wireline offerings, and also rebrand from time to time!. But they are not all the same, in terms of resolution, bedding definition, accuracy and application. But the sales engineers won’t really help you decide!
Fortunately, we have done that hard work of comparison, applicability, and reliability. Based on detailed commercial studies across the globe over the last 40 years, the conclusions are presented in a clear and concise manner for the casual BHI user.

Cretaceous – Paleogene Evolution of Bottom Currents in the Northern Carnarvon Basin, Northwest Shelf of Australia
Presented by Mulky Winata and Chris Elders (Curtin University)
Abstract

Bottom current deposits are common features along continental margins and are typically associated with slopes, either at the continental rise or adjacent to shallow shelves. In this study, we provide a detailed characterisation of Aptian to Rupelian deposits that developed in the centre of the Exmouth Plateau of the Northern Carnarvon Basin, Northwest Shelf of Australia, on c. 500 km wide ramp-type margin, characterised by gentle slope breaks between the coastline and the deep basin. Sediment mounds and moats initially developed during the Aptian to Turonian in clastic sediments in the southwest of the study area, whereas reduced sediment accumulation characterised the north-eastern sector. During the Turonian to Lutetian, a transition to carbonate sedimentation occurred. Interestingly, these features continued to develop, with the mounds gradually establishing themselves through aggradational growth, while the moats were infilled by sediments exhibiting complex structures, including small-scale mounds and incisions with a wide variety of different morphologies. From the Danian to Rupelian, there was a notable decrease in moat infilling and mound growth, leading to significant progradation of sediment toward the northeast. This final stage of sedimentation was characterised by stacked deep incisions, ridges, and conical depressions. Initial stages of deposition correspond to a period of time when a wide and open ocean was present to the north of Australia, but only narrow seaways and intracontinental rifts, associated with the breakup of Gondwana, were present to the west and south. The accelerated growth of mounds occurred during a period of accelerated separation of Greater Indian and Australia while cessation of bottom current activity corresponds to a period of rapid separation of Australia from Antarctica. The recognition and investigation of bottom current features provide new insights into the way in which oceanic circulation patterns may have evolved as the breakup of Gondwana progressed and can help our understanding of the processes that operate during the early stages of passive margin development and the formation of oceanic basins. In addition, more detailed knowledge of the sedimentary deposits that comprise the post-rift sequence in the Northen Carnarvon Basin can help improve understanding of velocity variations and drilling conditions in these sequences.

Source rock deformation and hydrocarbon accumulation controlled by a metamorphic core complex in the Kaiping Sag, northern South China Sea rifted margin
The recent discovery of hundred-million-ton-class oil fields in the Kaiping Sag, on the northern South China Sea rifted margin, is considered the first global breakthrough in hydrocarbon exploration within supra- detachment basins controlled by mature metamorphic core complexes (MCCs) at passive margins. 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.

Tracking the Fate of CO2 from Switzerland to Iceland with Geophysical Methods
Presented by Alba Zappone (Swiss Seismological Service)
Abstract

In-situ CO2 mineral storage is an effective way of reducing greenhouse gases and fighting global climate change.This technology is particularly interesting for countries that cannot rely on large CO2 storage capacities. Geophysical techniques can help characterise and monitor the storage reservoir. Seismic time lapse, electrical resistivity tomography (ERT) and gravity measurements are often used to track the CO2 plume. In the few existing in-situ mineral storage sites, monitoring relies almost only on geochemical methods.Geophysical methods are less established in this context. Seismic time lapse measurements are thought to be less efficient because the CO2 is dissolved in water before it is pumped in, so the local water is replaced by the CO2-enriched water, which makes the seismic velocity changes too small to detect.Carbonate precipitation happens slowly and makes very small velocity changes, mainly because the porosity decreases. ERT involves replacing the existing groundwater with CO2-charged water. This should lead to a decrease in resistivity. However, resistivity is only expected to increase when carbonates precipitate. Here, we present the results of testing geophysical methods to measure and check the CO2 storage site in Helguvik, Iceland, operated by CARBFIX. This study is part of the Swiss DemoUpCARMA project (https://demoupcarma.ethz.ch/) and uses a variety of scientific methods that have already been successfully tested in other CO2 storage experiments (e.g. Zappone et al., 2021). The Helgivik site is a pilot were CARBFIX is testing the efficiency to use sea water for dissolving CO2, in preparation for an upscaling of the site, the Coda Terminal that will receive and store 3 million tons of CO2 per year.
The pilot storage site lies on the Reykjanes Peninsula in Southwest Iceland, at about 15 km distance from the seismically and volcanically active rift zone. The CO2 is captured in Switzerland are shipped in isotainers (https://demoupcarma.ethz.ch/) to Helguvik . Here, after mixing with saline water, it is injected into the reservoir through a vertical borehole (CBI-01; Fig. 1) with an open section between 250 m and 420 m depth. Two additional vertical wells, CBM-03 and CBM-01, with depths of approximately 400 metres, have been drilled at distances of 30 metres and 100 metres along a northwest-southeast alignment, respectively, for the purpose of monitoring reservoir processes. Rock samples obtained from drill cuttings have been utilised in the characterisation of the stratigraphic sequence of the reservoir, in conjunction with borehole logging data. Furthermore, drill cores extracted from proximate boreholes have undergone laboratory analysis with respect to porosity network and flow properties, both prior to and following il laboratory exposure to CO2-rich saline water. Prior to and during the injection operations, cross-hole seismic measurements were conducted utilising a P-wave borehole sparker source and hydrophone chains. Simultaneously, single-hole electrical resistivity measurements were performed in all the wells. The background seismicity and the seismicity potentially induced by the injection operations were monitored via a backbone seismic network installed around the injection site, and by a seismic array of 3D nodal geophones. The data were streamed in real time to ETH Zurich and shared with all the project partners.
The multi-disciplinary approach reveals variability of the porosity in the basaltic layers, already evidenced by laboratory measurements (Stavropoulou et al, 2024), depicting a stratified velocity distribution with depth Single-hole electrical resistivity data corroborate the layering and is in agreement with the mineralogical data from cuttings. The remarkable consistency between ERT and crosshole seismic observations (Junker at al., 2025 ) highlights the efficiency of the methods to resolve thin layering structures and giving additional constraints to the borehole logging observations for permeable layers. Characterization with geophysical tools allows the continuity of the underground structures to be observed, in contrast to point borehole measurements. A permeability model, based on the crosshole seismic data is found to be in agreement with borehole spinner tests. Modeling on velocity anomalies due to precipitation of Carbonates reveal that that crosshole seismic can detect the precipitation of c.a. 17 kg/m3, corresponding to c.a. 100 t of injected CO2 at the scale of the pilot project.

PESA SA/NT March Luncheon
The Perth Basin: Seven years of learnings
Andrew Farley (Strike Energy)

Abstract:
Exploration in the Perth Basin commenced back in the 1960s, but it was the discovery of the Kingia gas play by AWE Energy in 2014 that kicked off the latest round of exploration and development. The Waitsia gas discovery inspired Strike Energy to enter the basin in 2018 with success at West Erregulla 2 in 2019 proving that porosity and permeability continues to preserved despite greater depth. To date, Strike has drilled 13 deep wells and acquired 6 new seismic surveys across the Permian Kingia and Jurassic Cadda/Cattamarra plays. This has led to the discovery of 4 new gas fields, one of which is now on production, and two which are being developed.

Event Details:

PESA WA March 20th Evening Talk: Tight Gas Sand Reservoir Evaluation: Basin-Centred Gas Accumulation (BCGA) & Implications on Production & EUR
2025-03-20 18:00 - 20:00 (Australia/Perth) | Faraday’s, 216 St Georges Terrace, Perth, WA, 6000, Australia
PESA WA invites you to a technical Evening Event Thursday 20th March.
Tight Gas Sand Reservoir Evaluation: Basin-Centred Gas Accumulation (BCGA) & Implications on Production & EUR
Presented by Greg Salter (Core Laboratories)
Tight gas sand (TGS) reservoirs often offer significant resource potential, however, they can pose many challenges including pay identification, the potential of formation damage, water and/or condensate block, as well as others. Another challenge may be what is the true water saturation? Is the water saturation controlled by capillary forces or is the reservoir a basin-centred gas accumulation (sub capillary-equilibrium) as published by a number of authors in the literature. This presentation will investigate the identification and characterization of basin-centred gas accumulation reservoirs and the implication on production and EUR.

Timings for the event:
Date: Thursday 20th March, 2025
Venue (Updated): Faraday’s, 261 St Georges Terrace, Perth
Time: 6pm – 8pm (Perth time)

Date & Time:
Thursday, 20 March 12:15 PM

Presentation Abstract:
Carbon dioxide geological storage is one option to enable Australia to reach net zero. 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.

Mega-Intrusions and Volcanic Ruins: A Tour of Magmatism in the Carnarvon Basin
Presented by Michael Curtis (Santos)
Abstract

The Northern Carnarvon Basin formed as a result of Late Jurassic rifting, and Early Cretaceous breakup of Greater India from the Australian continent. Magma was emplaced into the Exmouth Plateau and Exmouth Sub-Basin over an area of ~50,000 km2. Until recently the spatial distribution of this igneous system, and hence its potential impact on regional petroleum systems, was relatively unknown. The only references to the magmatic system were 1990s ‘blob’ maps created using 100+ km spaced 2D seismic, magnetic and gravity data, and references of penetrations of igneous rocks in well completion reports from ~8 wells and boreholes.
New interpretive work (the essence of my PhD), utilising SLB & TGS ultra-broadband 3D seismic data covering much of the Exmouth Plateau and Exmouth Subbasin, reveals the igneous system in all its glory! In this talk we will tour both its intrusive and extrusive components, asking why it is the way it is and what its current configuration might have meant for the development of Carnarvon Basin petroleum systems. We will attempt to answer why some intrusions are of record-breaking proportions (170+ km long), while others nearby are much much smaller (3 to 5 km diameter). We’ll also look at the eroded ruins of volcanoes (that until recently hadn’t been known to exist at all) and consider the original size of the volcanic complex, and the implications of volcano erosion on regional reservoir quality.

Unlocking the Potential of Carbon Capture
Presented by Huw Mason (EnergyQuest and Osprey Energy)
Abstract

In October 2024, EnergyQuest released its first report on Carbon Capture Utilisation and Storage (CCUS) titled “Unlocking the Potential of Carbon Capture”. The report provides an independent, in-depth review of Australia’s CCUS industry, outlining its necessity, key success factors for project execution, and the status and outlook of CCUS (including CCS) projects in the country. The technical analysis identifies five essential factors for a successful CCUS project, emphasising its crucial role in achieving the 2050 net-zero greenhouse gas emissions target. However, at the current rate of development, carbon capture and storage will fall short of meeting both global and Australian targets on time. Huw Mason will present an overview of the report’s findings and discuss the outlook for Australian projects.

Seismic interpretation of the Petrel Sub-basin CO2 Storage Opportunity
James Komenza
Abstract:
An integrated geologic and geophysical study of the Mesozoic storage resource in the Petrel Sub-basin (Bonaparte Basin). This study includes regional petrophysics, geomechanics, rock physics, seismic reprocessing and inversion in an area of sparse well and seismic data.
Although 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.

Wadjemup (Rottnest) Field Trip - Carbonate systems, sea level change and Quokkas
2025-02-27 08:40 - 16:00 (Australia/Perth) | Rottnest Island, Rottnest Island Visitors centre, 1 Henderson Ave,, Rottnest Island, WA, 6161, Australia
Wadjemup (Rottnest) Field Trip – Carbonate systems, sea level change and Quokkas– by bike
Led by Dr Moyra Wilson (University of Western Australia)
Though some 18 km offshore at the present day, during previous glacial lowstands Wadjemup (Rottnest Island) was joined to the mainland. Evidence of fluctuating sea-levels and environmental change is preserved both in the oral histories of the Whadjuk Noongar people but also the rocks and landforms of the island. Wadjemup offers excellent opportunity to explore classic carbonate aeolianites, coral reef, lacustrine and lagoonal deposits and marine features that are a conspicuous feature of the Pleistocene Tamala Limestone and associated units that outcrop over some 1000 km of WA’s coastline.
The trip, led by Moyra Wilson, will also facilitate broader discussions of approaches to palaeosea-level reconstructions, climate change and the coastal dynamics of WA’s younger geological evolution.
Please note that for insurance reasons this trip is only open to members. If you are not currently a member you will need to sign up before booking.

PESA WA invites you to our technical luncheon on Thursday 20th February.
Natural Hydrogen in Western Australia
Presented by Leon Normore (Geological Survey of Western Australia)

The nascent field of natural hydrogen investigations is expanding rapidly worldwide. 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.
Legislation 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. Supporting regulations for natural hydrogen exploration are currently being developed in conjunction with the transport and storage of greenhouse gas regulations.

To coincide with the soon to be launched Ascendience Geoscience global field analogue database Dr Mark Lisk will discuss the power of geological analogues using examples of unusual oil and gas discoveries from around the world:
The God’s Must Be Crazy – Unbelievable Play Defining Discoveries Providing Analogues for Future Success
Presented by Mark Lisk (Ascendience Geoscience)
Abstract

Geological analogues provide critical information to benchmark predictions across full cycle exploration and development projects. They seed ideas to recognise new plays and prospect opportunities to deliver the next cycle of discoveries. Since 2000 global exploration spend is estimated to have exceeded 2 trillion dollars; geological analogues offer the opportunity to claw back more value from that irretrievable sunk cost. Better still that accrued benefit helps not only the companies that paid the bill, rather learnings, both good and bad, are spread across the industry like creative intellectual fertiliser to feed the next flush of geological insights.
The best geoscientist is claimed to be the one who has seen the most rocks, making a good knowledge of geological analogues an essential element of the armoury of any good geoscientist or engineer. No matter how many years of experience you, your team or your company have it can never hope to match the experience of the industry as a collective.
Discoveries from around the world will be presented to demonstrate the critical role geological analogues play in guiding future success by highlighting three key elements:

Ideas find hydrocarbons, technology is merely the enabler
Rediscovery plays a major role in finding play-opening discoveries
Geological success looks blatantly obvious in hindsight

As famously stated, “we once thought we were running out of oil, when in fact we are running out of ideas”. We must commit the time to draw on the power of analogues to maximise success, reduce uncertainty and deliver better future business outcomes.

PESA WA February 13th Evening Talk: New Tricks for Old Dogs: Modelling for the Energy Transition
2025-02-13 18:00 - 20:00 (Australia/Perth) | Parmelia HIlton, 14 Mill Street, Perth, WA, 6000, Australia
PESA WA invites you to a technical Evening Event Thursday 13th February.
New Tricks for Old Dogs: Modelling for the Energy Transition
Presented by Mark Bentley (Langdale Geoscience)
So, the plan is to store CO2 …
If we’re involved in making reservoir and simulation models for oil and gas production, what do we have to do differently now for the world of storage? On the face of it, these are just gas disposal schemes (simple). On closer inspection, it’s not quite like that, and it turns out it’s much more interesting (harder).
This short talk looks at some areas of change and the aspects we need to get right if our forecasts are to be meaningful at all. There’s a clear shift from sedimentary to more structural themes (which we have to be much better at), a replacement of familiar concepts such as in-place resource volumes and recovery factor to less familiar ideas of storativity and storage efficiency and a rethink of the importance of heterogeneity in the face of different fluids and in a non-isothermal world.
The scales we model at will need to be different, and so will the timescales. There’s also the over-arching issue that best solutions are likely to lie in aquifers, yet most projects on the drawing board are for depleted gas fields. Some technical reservoir issues are clearly less important than they were during production, but others are more critical in areas where our supporting data is limited.
Not really prosecco – more like olive oil.

February 2025 Workshop - Good Model: Bad Models – How Can We Tell?
2025-02-13 | Parmelia HIlton, 14 Mill Street, Perth, WA, 6000, Australia
Good Model: Bad Models – How Can We Tell?
A one-day workshop with Mark Bentley, 13th February 2025
Reservoir and simulation models are widely used to generate forecasts and support decision-making in operating companies, yet the results often disappoint. Where do models ‘go bad’, and what can we do to address the disappointments?

Firstly: sometimes we do OK. There are excellent examples of useful models which help support good development decisions and help move us forward.
However, there is also a broad tendency towards over-optimism in modelling, a habit of making forecast ranges which are too narrow and key heterogeneity is often lost in the modelling process, leading to misleading predictions.
In this one-day workshop, common causes are shared, along with suggested solutions and, for those who use or review models, things to query.

Workshop will take place at the Parmelia Hilton Hotel, Perth on the 13th February 2025:
