SUMMARY:2024 PESA WEBINAR SERIES: Forward Modelling for Stratigraphic and Structural Analysis in Complex Mini-Basins\, Offshore Sureste Basin\, Mexico (Fugro)
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. \nForward Modelling for Stratigraphic and Structural Analysis in Complex Mini-Basins\, Offshore Sureste Basin\, Mexico \nPresented by Donald Christie (Fugro) \nAbstract \n\nStructurally 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). \nFocusing 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.\nReduced-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.

SUMMARY:February 2025 Workshop - Good Model: Bad Models – How Can We Tell?
DESCRIPTION: Good Model: Bad Models – How Can We Tell? \nA one-day workshop with Mark Bentley\, 13th February 2025 \nReservoir 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? \n\nFirstly: sometimes we do OK.  There are excellent examples of useful models which help support good development decisions and help move us forward. \nHowever\, 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. \nIn this one-day workshop\, common causes are shared\, along with suggested solutions and\, for those who use or review models\, things to query. \n\nWorkshop will take place at the Parmelia Hilton Hotel\, Perth on the 13th February 2025: \nMembers: $400 \nNon-Members: $500 \nStudent Members: $100

SUMMARY:PESA WA February 13th Evening Talk: New Tricks for Old Dogs: Modelling for the Energy Transition
DESCRIPTION:PESA WA invites you to a technical Evening Event Thursday 13th February.\nNew Tricks for Old Dogs: Modelling for the Energy Transition\nPresented by Mark Bentley (Langdale Geoscience) \nSo\, the plan is to store CO2 … \nIf 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). \nThis 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. \nThe 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. \nNot really prosecco – more like olive oil. \n  \nTimings for the event: \nDate: Thursday 13st February 2025 \nVenue: Parmelia Hilton Hotel\, Perth \nTime: 6pm – 8pm (Perth time) \n  \n\nPESA Members:                                $40.00 (PESA Members must Log on to the PESA website to purchase) \nNon-members:                                 $50.00 \nPESA Students Members:              Free (registration is essential)

SUMMARY:2025 PESA WEBINAR SERIES: The God’s Must be Crazy: Unbelievable Play Defining Discoveries Providing Analogues for Future Success
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. \nTo 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: \nThe God’s Must Be Crazy – Unbelievable Play Defining Discoveries Providing Analogues for Future Success \nPresented by Mark Lisk (Ascendience Geoscience) \nAbstract \n\nGeological 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. \nThe 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. \nDiscoveries from around the world will be presented to demonstrate the critical role geological analogues play in guiding future success by highlighting three key elements: \n\nIdeas find hydrocarbons\, technology is merely the enabler\nRediscovery plays a major role in finding play-opening discoveries\nGeological success looks blatantly obvious in hindsight\n\nAs 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. \nFor a copy of the presentation slides that contains references and attribution for the content please visit the Ascendience Geoscience website here: \nhttps://ascendience-files-open.s3.ap-southeast-2.amazonaws.com/Lisk_PESA_Webinar_Final_FPR180225.pdf

SUMMARY:PESA WA February Technical Lunch: Natural Hydrogen in Western Australia
DESCRIPTION:Hosted with thanks to our Platinum sponsor SLB: \n  \n \nGold Sponsors IKON Science and DUG: \n                                              \n  \nand Silver Sponsors Delft and Qeye: \n              \n\nPESA WA invites you to our technical luncheon on Thursday 20th February.\nNatural Hydrogen in Western Australia\nPresented by Leon Normore (Geological Survey of Western Australia)\n\nThe 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. \nLegislation 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. \nTicket Prices: \nMember (Early Bird): $69.00 \nConcession Member [Retired or Hardship]: $59.00 \nStudent Member: $10.00 \nGraduate Member: $20.00 \nNon-Member: $99.00 \nMember (Non-Early Bird): $79.00 \nEarly bird\, Concession\, Student and Graduate Member pricing ends Thursday (1 week prior) at 5pm (AWST). All ticket sales close at 5pm Tuesday (2 days prior). \n

SUMMARY:Wadjemup (Rottnest) Field Trip - Carbonate systems\, sea level change and Quokkas
DESCRIPTION:Wadjemup (Rottnest) Field Trip – Carbonate systems\, sea level change and Quokkas– by bike\nLed by Dr Moyra Wilson (University of Western Australia) \nThough 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. \nThe 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. \nPlease 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. \nPrices: \nMembers:                     $100 \nStudents:                       $50 \nTickets close the Thursday prior at 5pm. \nNote: This price is for the instruction only. It does not include ferry fares\, bike hire or lunch. These need to be arranged separately at your own cost. \nGetting there: \nMeeting point: Rottnest Visitor Centre: 8.40 am\, finish by 4 pm in time for a 4.30 pm return.  Recommendation to save time hire your bikes from the ferry company. \nhttps://rottnestexpress.com.au/ \nhttps://www.sealink.com.au/ \nhttps://booking.rottnestfastferries.com.au/

SUMMARY:PESA SA/NT February Luncheon
DESCRIPTION:PESA SA/NT February Luncheon\nSeismic interpretation of the Petrel Sub-basin CO2 Storage Opportunity \nJames Komenza\nAbstract: \nAn 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. \nAlthough 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.
