SUMMARY:2024 PESA WEBINAR SERIES: Sediment Provenance Analysis of the Early Permian Reservoirs of the Perth Basin (Chemostrat)
DESCRIPTION:Kindly supported by Rock Flow dynamics  \n  \nThis live webinar will take place at: \n11am              – Perth\n12.30pm       – Darwin\, Adelaide\n1pm                – Brisbane\, Canberra\, Hobart\, Melbourne\, Sydney \nUse the calendar link on this page to add this event in to your own calendar at the correct local time for your location. \nTickets are free for members (please log in to see this) and $10 for non members. \nPlease buy your tickets and immediately follow the link in the ticket e-mail (not the calendar invite or this webpage\, which is just generic and not event specific) to set up your registration with the webinar software well in advance of the time of the talk. Once registered with the webinar software you will receive a reminder e-mail 1 hour beforehand. \nSediment Provenance Analysis of the Early Permian Reservoirs of the Perth Basin \nPresented by Stuart Munday (Chemostrat) \nAbstract \n\nThe 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.

SUMMARY:PESA ACT/NSW October Technical Lunch
DESCRIPTION:PESA NSW September Technical Meeting\nMelbana in Cuba: the Amistad-1 success story\nMelbana 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). \nIn 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). \n\nUnit 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.\nUnit 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.\nUnit 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.\n\nLogged 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. \nUnit 1B has now been completed for future production\, whilst Units 1A and 3 have been suspended for potential future development and production. \nIn March 2024 McDaniel provided a resource update on the Unit 1B; \n\n46 MMbbls (P50) Contingent Resources – Development Pending in the eastern section of the greater Alameda field in the vicinity of the existing wells.\n90 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.\n\nA 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.

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.

SUMMARY:PESA SA/NT Branch October Luncheon
DESCRIPTION:An emerging new Petroleum System with world-class plays in the \nTorres Sub-Basin\, Offshore Papua New Guinea \nTim Rady1 and John Chambers2  \n1 Geomorph Energy \n2Larus Energy Limited \n\nABSTRACT\nThe 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: \n\nMiocene deep-water clastics in a large submarine Miocene to Pliocene foldbelt\nPinch-out plays of Miocene to Pliocene age against a basement high\nPalaeogene carbonate build-ups on basement highs\n\nThis 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. \nThe 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. \nThe 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 \n\nEvent Details:\nThursday\, 24 October 2024\nLuncheon: 12 pm for a 12:30 pm start \nPlace: Ayer’s House\, 288 North Tce\, Adelaide \nIncludes a 2-course lunch and drinks \nBookings close 1 pm Monday\, 21st October 2024 \nAny late bookings will incur an additional $20 fee.

SUMMARY:PESA QLD Lunch\, 24 October : Where comes the gas from\, where does it go? Southern Denison Trough CO2 storage possibilities from a geological perspective
DESCRIPTION:This month PESA Queensland welcomes Alison Troup to present a technical luncheon looking at the CO2 storage potential of the southern Denison Trough. \nThe Technical Lunch will be held at the Brisbane Hilton Hotel\, in Room 83 (Level 8). \nFor detailed directions\, see explanation below. \nPlease note the Early Bird ticket pricing cut-off times described below. \n\n\n\nPresentation:\nWhere comes the gas from\, where does it go? ? Southern Denison Trough CO2 storage possibilities from a geological perspective\n\n\nVenue:\nHilton Hotel Brisbane\, 190 Elizabeth?Street\,?Brisbane QLD 4000\nRoom 83\, Level 8\n(Detailed directions below)\n\n\nDate & Time:\nThursday\, 24 October 12:15 PM\n\n\n\n  \nPresentation Abstract: \nThe 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. \nSandstones 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. \n\nTickets for the Technical Luncheon can be purchased below. \nPlease be advised of the early bird cut-off date. \nEarly bird pricing will now remain available up until Monday\, 21 October 12:00 PM after which\, standard pricing will come into effect. \nTo avoid disappointment please register before that date and time. \n\n\n\n\n\n\n\n\n\n\nPESA Members ? $55\nNon-Members ? $75\nStudent / Retired Members ? $30\n\n\n\n\n\nLate ticket sales up to Wednesday\, 20 October 12:00PM will be available for $95 for all tickets – subject to availability.

SUMMARY:2024 PESA WEBINAR SERIES: WA Carbon Dioxide Geological Storage Atlas (GSWA)
DESCRIPTION:Kindly supported by Rock Flow dynamics  \n  \nThis live webinar will take place at: \n11am | Perth\n12.30pm | Darwin\n1pm | Brisbane\n1:30pm | Adelaide\n2pm | Canberra\, Hobart\, Melbourne\, Sydney \nUse the calendar link on this page to add this event in to your own calendar at the correct local time for your location. \nTickets are free for members (please log in to see this) and $10 for non members. \nPlease buy your tickets and immediately follow the link in the ticket e-mail (not the calendar invite or this webpage\, which is just generic and not event specific) to set up your registration with the webinar software well in advance of the time of the talk. Once registered with the webinar software you will receive a reminder e-mail 1 hour beforehand. \nWA Carbon Dioxide Geological Storage Atlas \nPresented by Julie Cass (GSWA) \nAbstract \n\nIn 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. \nKey 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. \nDepth 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. \nTo 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. \nA 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. \nIn 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. \nAll datasets and results are available for download from WAPIMS via the CO2 Storage Atlas tile.
