PESA SA/NT Branch September Luncheon- 26 September
2024-09-26 12:00 - 14:30 (Australia/Adelaide) | Ayers House – Ballroom, 288 North Terrace, Adelaide, South Australia, 5000
Salt Cavern storage potential of the Polda Basin, South Australia
Glenn Toogood, entX, and Tim Rady, Geomorph Energy

The Polda Basin is a Neoproterozoic to Jurassic sedimentary basin, extending from the Great Australian Bight to the central Eyre Peninsula, South Australia. It has previously been explored for petroleum, uranium, coal, groundwater, base metals, potash and diamonds. There has been renewed interest in the Polda Basin for its underground gas storage potential in salt caverns, given that Mercury-1 encountered >1200m of massive halite within Neoproterozoic red beds in the central offshore basin.
entX Limited were granted Gas Storage Exploration Licences (GSEL) 781 and 784 and have been actively studying the basin to assess the likelihood of the proven offshore salt extending onshore, where it may be engineered into caverns for underground gas storage (UGS) sites. UGS can provide gigawatt-scale storage of H2 gas and significantly reduce the levelized cost of storage. Such an asset would provide key advantages to H2 project concepts, including DRI green steel from magnetite, green ammonia and biofuels.
To assess the prospectivity for salt onshore and correlate the stratigraphy across the basin, entX have taken a multi-disciplinary approach, reviewing all available data and literature and integrating seismic reprocessing, ICP-MS/OES and XRF analysis, visual core and cuttings interpretation, core density measurements, spectral scanning and gravity forward modelling. Following this work, the onshore Polda Basin has emerged as highly prospective for both salt and natural hydrogen. This talk will summarise the technical work undertaken, new insights about the stratigraphy and plans for future data acquisition.

Sediment Provenance Analysis of the Early Permian Reservoirs of the Perth Basin
Presented by Stuart Munday (Chemostrat)
Abstract

The sediment provenance of Early Permian reservoirs (‘Kingia’ and High Cliff sandstones) of the onshore North Perth Basin is poorly understood. Bulk rock inorganic geochemistry, detrital zircon geochronology and heavy mineral data have been used to assess spatial and temporal changes in provenance in the vicinity of the Waitsia, Lockyer Deep, West Erregulla and Beharra Springs Deep discoveries. The geochemical data provides a chemostratigraphic framework for the Early Permian that can be confidently correlated throughout the basin. The detrital zircon and Raman data have recognised significant regional variabilities. The zircon data defines western and eastern regions that were separated and/or infilled by different depositional systems, likely defined by the Mountain Bridge Fault. Raman analysis demonstrates that the High Cliff and ‘Kingia’ sediments in the vicinity of Waitsia have different zircon age populations and heavy mineral assemblages, with the ‘Kingia sandstone’ dominated by apatite indicating access to a granitic source at this time. This is poorly represented by wells in the northern Dongara Terrace and Allanooka Terrace, where sediments are dominated by garnet. Analysis of Lockyer Deep and West Erregulla discovery wells in the northern Dandaragan Trough, also demonstrate only minor amounts of apatite, but also include a significant mafic component, the source of which is uncertain. The geochemical data demonstrates that the top of these reservoirs is defined by a highly consistent change in provenance, coincident with a switch to garnet-rich sediments and different dominant zircon age populations.

Melbana in Cuba: the Amistad-1 success story
Melbana Energy drilled the Alameda-1 discovery well in onshore Cuba in 2021. By 2022 the discovery was independently certified by McDaniel (A Canadian based Reserves Certifier with extensive experience in Cuba) to contain over 5 billion barrels of oil in place (best estimate) and 267 million barrels of recoverable oil (best estimate).
In 2023 Melbana followed up the Alameda-1 well with the successful Amistad-1 appraisal well which was designed to test the uppermost sheet of reservoirs in the Alameda field (Unit 1A, 1B, 2 and 3).

Unit 1A recovered 11.7° API oil with 3,783 cP viscosity at surface from a 63 metre MD interval starting from 445 metres MD. Although flow rates at surface were not established 40 barrels of oil flowed unassisted to surface (through a 32/64” choke), exceeding expectations.
Unit 3 intercepted 200 metres updip and 500 metres to the south of the Alameda-1 intercept and confirmed moveable oil of a similar quality to Unit 1A. Testing indicated the potential to flow at ~750 bopd. The Unit 2 DST did not demonstrate moveable hydrocarbons to surface at the location tested.
Unit 1B recovered 19.4° API oil with 5.7 cP viscosity at surface from a 70 metre TVD perforated section – less than 20% of the total Net Pay for Unit 1B (when incorporating fractures). Stabilised unassisted flow rate to surface of 1,235 bopd measured over 12 hours on a 36/64” choke, peaking at 1,903 bopd.

Logged Net Pay for the entire Amistad Formation is 346 metres TVD using 9% porosity, 50% Sw and 40% VSh cutoffs this net pay increases to 615 metres when the highly fractured limestones are incorporated (45% of the gross interval). Flow from the fractured interval has been proven by acquisition of production logs validating the incorporation of fractures into the net pay equation.
Unit 1B has now been completed for future production, whilst Units 1A and 3 have been suspended for potential future development and production.
In March 2024 McDaniel provided a resource update on the Unit 1B;

46 MMbbls (P50) Contingent Resources – Development Pending in the eastern section of the greater Alameda field in the vicinity of the existing wells.
90 MMbbls (P50) Prospective Resources of assigned in the western part of the field to reflect the uncertainty associated with being away from the existing wells. However, McDaniels assigned a 70% chance of discovery to the prospective resource reflecting the low- risk nature of this area (given it is updip from the existing discoveries within the field). The risk associated with this area is based on reservoir deliverability.

A preliminary field development plan is being developed for exploitation of Unit1B and an additional two wells focussing purely on production from Unit1B are being planned with the aim of initiating international oil export from Cuba.

The Gulf of Papua: Fresh Insights Into a Frontier Basin
Presented by Lauren Found (Searcher)
Abstract

Despite covering an area roughly equivalent to the state of Victoria, the offshore Gulf of Papua in Papua New Guinea (PNG) remains vastly underexplored, with less than thirty exploration wells drilled over the last seventy years. However, although well data is lacking, there is a wealth of geotechnical data covering the Gulf, allowing for detailed studies to be undertaken, challenging long-held paradigms about the crustal nature, regional architecture and hydrocarbon prospectivity. The basin-scale studies can also be integrated into more detailed prospect-level evaluations as new geophysical technologies allow for high-resolution 3D seismic to aid in de-risking perceived risks in source development and reservoir facies, as observed with the Nanamarope 3D MSS.

An emerging new Petroleum System with world-class plays in the
Torres Sub-Basin, Offshore Papua New Guinea
Tim Rady1 and John Chambers2

2Larus Energy Limited

ABSTRACT
The Papuan Basin is the only basin with production in Papua New Guinea but is relatively unexplored for a typical Australian Continental Margin Mesozoic basin. It hosts the Kutubu Oil Field Developments and the PNG LNG project, as well as several gas fields that are planned to be developed in the coming years, but its southeastern extension, the Torres Sub-Basin, remains undrilled. Modern proprietary and regional multi-client seismic data in the offshore Torres Sub-Basin is now revealing an active Petroleum system with a generating Late Cretaceous Source rock and three main identified play types:

Miocene deep-water clastics in a large submarine Miocene to Pliocene foldbelt
Pinch-out plays of Miocene to Pliocene age against a basement high
Palaeogene carbonate build-ups on basement highs

This presentation will focus on the Miocene to Pliocene submarine foldbelt plays within the Larus Energy-operated PPL579 license area that was covered by the Nanamarope 3D broadband PSDM seismic survey (acquired in 2023 by Larus Energy and Searcher). The pinch-out play is within the recently awarded Larus Energy-operated PPL695 license in the foreland basin south of the foldbelt, while TotalEnergies is proposing to test the Palaeogene carbonate play with the Mailu-1 well in 2025.
The Nanamarope 3D seismic provides high-resolution images of large-scale submarine fan complexes, deposited during the Mid-Miocene, linked to active tectonism and the formation of the proto–Owen Stanley Range. The images suggest significant reworking of these turbidite systems by bottom currents into likely high reservoir quality contourite deposits with a wide spectrum of features formed during synchronous and asynchronous interaction of turbidity flows and bottom current activity. It is observed that bottom currents provide a mechanism to redistribute coarser-grained material up-slope and beyond the limits of the traditional turbidite fairway.
The new 3D seismic has allowed Larus to complete detailed structural mapping, update GDE interpretations, identify evidence for hydrocarbon migration and integrate petroleum systems and seismic synthetic forward modelling to derisk the prospectivity. Larus Energy is planning on drilling the giant Nanamarope Prospect in 2025 which, if successful, will open a large new play fairway for exploration and development and provide a much-needed revenue source for the nation of Papua New Guinea

Date & Time:
Thursday, 24 October 12:15 PM

Presentation 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.

WA Carbon Dioxide Geological Storage Atlas
Presented by Julie Cass (GSWA)
Abstract

In May 2021, the Ministerial Taskforce on Climate Action identified CO2 sequestration as a key priority, leading GSWA to receive funding in July 2022 to develop a CO2 Storage Atlas for Western Australia. The atlas incorporates updated geological datasets and new interpretations to assess CO2 storage potential across the onshore and State waters of the Perth, Southern Carnarvon, Northern Carnarvon, Canning, and Officer Basins.
Key to this project is regional subsurface mapping, which involves interpreting seismic data collected by petroleum companies over the past 70 years. The interpretation workflow includes loading digital seismic (SEGY) and well (LAS) data into Kingdom software. Since most available seismic data is in two-way time, mapping is first conducted in time before converting it to depth using various techniques. Mappable horizons identified on seismic data are tied to formation boundaries penetrated by petroleum wells and drillholes with downhole velocity data. As a byproduct, this project also involves capturing and cleaning up velocity survey data from well reports.
Depth mapping for the Officer and Perth Basins has been completed, and interpretation work continues for the Canning, Northern, and Southern Carnarvon Basins. Key features noted in the Perth and Officer Basin maps regarding CO2 storage potential include fault location and density, reservoir formation depths and thickness, and, in the Officer Basin, the presence of salt bodies.
To support the regional assessment of reservoir quality for the CO2 Storage Atlas project, 8,070 well log LAS files were standardized into a uniform format using Python. This standardization ensures consistent depth references, mnemonics, units, coordinates, and well names, enabling AI-based analysis. Furthermore, routine core analysis (RCA) data has been quality-checked and reformatted to enhance accessibility.
A subset of petrophysical interpretations have been completed for the Perth and Canning Bains. Storage targets were identified using a shale volume cutoff of 30% and an effective porosity cutoff of 10%, revealing the Perth Basin’s sand-prone nature. Given the highly faulted nature of the Perth Basin, the impact of faulting was evaluated through the interpretation of apparent formation water salinity. Significant intervals of Archie-quality sand are present in most wells, allowing for accurate assessments of apparent water resistivity. Water salinity changes frequently in each well but does not follow normal shale dewatering trends. This implies that vertical heterogeneity is significant but lateral movement of water across faults is expected, most likely through sand-on-sand juxtaposition. This evaluation also highlights which formations act as competent and reliable seals.
In summary, the petrophysical interpretation indicates that the Perth Basin is highly sand-prone. While structural containers are likely to be small, the presence of reservoir heterogeneity will enhance unstructured containment.
All datasets and results are available for download from WAPIMS via the CO2 Storage Atlas tile.

PESA WA November 21st Evening Talk: Top seal and compartmentalisation in the Kingia Play, implications for porosity preserving plays.
2024-11-21 18:00 - 20:00 (Australia/Perth) | The Shoe, Shop GSO7 Yagan Square, 376 - 420 Wellington St, Perth, WA, 6000, Australia
PESA WA invites you to a technical Evening Event Thursday 21st November.
Top Seal and Compartmentalisation in the Kingia Play, implications for porosity preserving Plays.
Presented by Alex Fuerst (Molyneux Advisors)
In the Kingia play of the North Perth Basin, significant compartmentalisation is observed across the basin and within individual fields, despite the sand-on-sand juxtaposition. This compartmentalisation manifests in both pressure and phase (gas/water) variations. Cemented fractures are observed near fault zones in Perth Basin wells. This results in decreased permeability near faults, as evidenced by local wells in the Perth Basin.
SEM images show fractures within grains of grain coated sands are sufficient to serve as nucleation sites for quartz cementation. In contrast, within the Irwin River Coal Measures (IRCM), the grain surfaces alone provide sufficient sites for cementation. The IRCM sands exhibit permeabilities that are characteristic of seals, with samples displaying quartz cementation, kaolin cementation, or a combination of both.
The implications for play risk / play maps are significant. Shallower Kingia penetrations face an unproven top seal due to the less cemented IRCM, potentially explaining the multiple shallower exploration failures. At greater depths, the presence of more complex faulting may enhance fault seal integrity and lead to more intricate trap configurations. However, this also likely increases development complexity due to reservoir compartmentalization. The observed improvement in IRCM sealing capacity with depth suggests broader implications for exploring deeper grain-coated plays, allowing for a wider range of facies to be considered as potential seals.

Date: Thursday 21st November, 2024
Venue: The Shoe Bar, Yaga Square, Perth

chris.cubitt@sa.gov.au

Abstract:
South Australia took the lead nationally in enabling exploration licences for natural hydrogen on 11 February 2021 when amendments to the?Petroleum and Geothermal Energy Regulations 2013?declared hydrogen, hydrogen compounds and by-products from hydrogen production ?regulated substances?. Following on from this, seven companies have lodged over 40 applications for PELs targeting natural hydrogen over the State?s basins and crystalline basement provinces. PEL 687 is the first licence in Australia targeting natural hydrogen and was granted to first movers Gold Hydrogen Pty Ltd in July 2021 over Yorke Peninsula and Kangaroo Island. The second licence (PEL 691) was granted to H2EX in June 2022 over eastern Eyre Peninsula. An update will be given with respect to current exploration activities in both active licences and with reference to the current understanding of natural hydrogen prospectivity across South Australia.

VIC/TAS PESA-SPE-ASEG joint Christmas Lunch and Talk 2024
2024-12-04 12:00 - 14:00 (Australia/Melbourne) | Henry & The Fox, 525 Little Collins Street, Melbourne, Victoria, 3000, Australia
PESA VIC/TAS are holding a joint Christmas Lunch together with our friends from SPE and ASEG. We would like to thank our friends from SPE who are have organised this event and are subsidising it by opening it to our PESA memebrs we well as for all ASEG members.

Before our lunch there will be a technical talk by SPE distinguished lecturer Juliane Heiland (SLB), titled:
Geomechanics for Field Development and Production Management – experience from two decades of reservoir geomechancis studies
Abstract:
Modern numerical 3D Geomechanical models can provide detailed subsurface geological understanding to predict failure events impacting reservoir engineering and production management.
Geomechanical models have become a standard input for drilling engineering and well planning and in many companies geomechanical teams today work closely with drilling teams. The same integrated modeling and engineering approach has not taken hold yet when considering reservoir engineering and production management, where the use of geomechanics models and close cooperation between geomechanics and engineering teams can still be improved.
My presentation shows how modern models provide the geomechanical tools to analyse potential wellbore and reservoir failures that can impact production. I will show the useful characteristics a geomechanics model should have to solve production challenges and influence reservoir management decisions.
Speaker’s Bio:
Juliane Heiland is a Geomechanics Advisor at SLB focussing on rock and soil mechanics applied to a wide range of engineering domains. Her first degree in Engineering Geology from the Technical University Munich gave her a solid geological sciences foundation applied to civil engineering and tunneling. A PhD (from 1994 to 1998) focussed on landslide research in Italy, Germany and the Czech Republic. Academic post-doc research at the GeoForschungsZentrum Potsdam focussed on laboratory solutions through high-pressure rock mechanics experiments applied to problems in tunneling and geothermal well productivity.
She joined SLB (formerly Schlumberger) as a research scientist in 2001 and worked six years in geomechanical research towards sanding and perforating. In 2007, Juliane moved into field consulting services providing geomechanics engineering solutions to SLB clients in Africa and Europe. After a brief move to the operator side of the industry with Maersk Oil, providing wellbore stability analysis for drilling planning, she returned to SLB in 2015. As Geomechanics Advisor since 2018 Juliane concentrates on training the next generation of geomechanics engineers at SLB and with operators in the wider industry as well as providing input to consulting studies worldwide.
This event is open to members and non-members.

Connecting the Links – Enabling Successful CCS Value Chains
Presented by Katarina van der Haar and Stephen Stokes (Wood)
Abstract

Highly industrialized, densely populated countries like Japan, Singapore and Korea are actively pursuing CCS and are looking to transport CO2 to international jurisdictions with Australia alone providing considerable storage potential. Technically, the entire value chain is possible, yet challenges that are specific to CO2 need to be overcome.
Wood, a global engineering consultancy, has been actively involved in over 50% of the world’s CCS studies. Encompassing concept, pre-FEED, FEED execution and operation stages across the entire CCS value chain, our studies covered capture from traditional oil and gas operators, power generation, refineries, and hard-to-abate industries, as well as conditioning processes such as dehydration, liquefaction, and temporary storage, and transportation via pipeline or ship to storage sites. In this presentation, Stephen Stokes and Katarina Van Der Haar will cover a selection of the latest technological insights and lessons learned from Wood’s involvement in over 200 CCS studies worldwide. The presentation will cover a range of topics, including CCS multi-emitter hubs and the use of common pipelines, the importance of impurities in CO2 streams and alignment of CO2 specifications, repurposing of existing infrastructure, and insights from cross-border liquefied CO2 shipping into Australian storage locations. Through case studies from several state-of-the-art CCS projects from around the world, Stephen and Katarina will highlight the critical importance of information sharing, collaboration, and alignment across the entire value chain for all CCS proponents.

PHILIPPINES GEOLOGY AND PETROLEUM POTENTIAL
The petroleum potential of the Philippines has long been regarded by “industry experts” as average at best. The Philippines is a country with active crustal plate movements, subduction zones, regional wrench faults and active volcanoes located on the western edge of the Circum-Pacific “Ring of Fire”.
Geologically, the Philippines is the eastern rifted edge of Asia, which was initially separated by rifting and the development of the South China Sea commencing in the Eocene. Initial rifting resulted in the deposition of an Eocene clastic section, dominantly non-marine with extensive coal development.
The appearance of oceanic crust in the late Oligocene initiated the drift phase with development of extensive barrier and pinnacle limestone reefs on the upthrown sides of the large normal faults created by rifting. These Oligocene to Early Miocene reefs created the reservoir for many of the large gas fields discovered to date, eg Malampaya, which largely sourced the gas from the underlying coal measures. About 10 million years ago the Asian, Pacific and Australian crustal plates collided creating compression, subduction, regional wrench faults and volcanism. This tectonic activity caused regional uplift, particularly in the west of the Philippines centred on east Palawan and deposition of Early-Mid Miocene sedimentary deposits, dominated by an extensive deep water marine clastic section with excellent quality sandstone reservoirs. Waxy oils waxy with associated gas are the main hydrocarbon discoveries. These hydrocarbons have been sourced by both marine and non-marine organic matter.
The Late Miocene to present day sedimentary section is dominated by a thick section of marine marls and limestone reefs with associated volcanism adjacent areas of plate to subduction. The Tertiary to Recent geology of the Philippines is very similar to that recorded in Indonesia, Thailand, Vietnam and parts of offshore China. The Philippines experienced extensive petroleum exploration in the 1960s but concerted exploration efforts since then have been patchy. Whilst trap integrity is considered the main exploration risk, there is still excellent potential for oil and gas discoveries of significant size. Gas2Grid Limited has been active with onshore petroleum exploration in the Philippines since 2005 and the author since 1981.

2024-12-12 12:00 - 14:00 (Australia/Perth) | Parmelia HIlton, 14 Mill Street, Perth, WA, 6000, Australia
PESA WA invites you to our Christmas Technical Luncheon on Thursday 12th December
Talk by Ernie Delfos – ‘Colour of Rocks’

Having spent over 40 years in the great Oil & Gas industry, you know what part of your career you are in when you are invited to give a talk on it. It seemed an appropriate invitation to accept when in July this year I realised that my passion for geology came a full circle with a trip to the Bungle Bungle Range in the Kimberley region. The magnificent beehive structures and their alternating red and yellow colouring caused the posing of the question why? The same question as a teenager I asked what causes the colour of rocks and who studies this?

Transitioning from full time employment to “my time” employment is exciting and highly recommended if affordable and I am excited to share experiences, lessons learned, and yarns on all these influences and mentors that shaped my career so far.
I strongly believe there is plenty of running room in the future demand of hydrocarbons to improve global standards of living, while we find better ways to cut emissions and seek alternatives.

Annus Mirabilis
The breakthrough year when petroleum geoscience changed forever
Rhodri Johns

Abstract:
In a single remarkable year, several key papers and books were published that revolutionised the petroleum geosciences.
Some of these publications introduced groundbreaking ideas, concepts, and methodologies that stunned and astonished both academia and the petroleum industry. Others synthesised state of the art in disciplines such as sedimentology and geochemistry, building on developments from the previous decades, like pieces of a jigsaw puzzle falling into place; these works not only led to a more innovative approach to petroleum exploration but also laid the foundations for systematic basin analysis, play analysis, petroleum systems analysis, and risk analysis – approaches that would emerge as essential tools for the petroleum industry in the 1980/90s and beyond.
What were these pivotal publications, and who were their authors? How and where did these ideas and breakthroughs originate, and how were they received by both academia and the industry?
Rhodri Johns will tell this story from a personal perspective, offering new insights from those closer to the action.

Forward Modelling for Stratigraphic and Structural Analysis in Complex Mini-Basins, Offshore Sureste Basin, Mexico
Presented by Donald Christie (Fugro)
Abstract

Structurally active mini-basins characterize continental margins such as deep-water Angola, Brazil, North Borneo, and the Gulf of Mexico, and the stratal architecture of these mini-basins is dominantly controlled by the interplay of structural growth and sediment supply. We simulate and reproduce the observed stratal geometry using a reduced-complexity, fast computational model (Onlapse-2D), and through a process of iteration the model output is matched to available subsurface control (well logs, 3D seismic data).
Focusing on the late Miocene tectonostratigraphic evolution of a complex mini-basin in the offshore Sureste Basin, Mexico. Two cross-sections were chosen to intersect the existing well, one parallel to the axis of the minibasin and the other perpendicular to it, and two Onlapse models were generated from each. A good first-pass match between model output and geological observations was obtained, which allowed us to identify and separate the effects of two distinct phases of compressional folding and a longer-lasting episode of salt withdrawal/diapirism, and to determine the timing of these events.
Reduced-complexity simulation is an efficient and effective approach to understand the tectonostratigraphic evolution of complex deep-water minibasins. Onlapse models use real seismic interpretations of real active structures and by matching the forward model to the existing well data, it can provide insight into the geometry and timing of the controlling structural processes; demonstrate the changing proportion of background vs. sediment-gravity-flow deposits; and aid in the identification of key erosional or constructional surfaces within the stratigraphy.

PESA NSW February Technical Talk
AI for Fun and Profit
Ian’s talk will include a brief history of AI and then introduce the concept of Large Language Models (LLM’s) – these include systems such as ChatGPT, CoPilot, Gemini, Claude and others.
It will also present issues with LLMs including the way they can hallucinate, their poor ability with simple arithmetic and recent developments that suggest we are rapidly reaching the situation where AI systems can think and plan and also scheme and lie.
The main part of the talk will describe a recently introduced Google product, Notebook LM, and how it differs from the more well known LLMs as mentioned above.
