Any technical project will have methods for “monitoring and verifying”\, but this mindset can lead to the assumption that M&V is a technology problem. Monitoring methods\, be they geophysical\, geochemical\, or environmental\, are often at the forefront of discussion. In fact\, this distracts attention from the need clearly to identify the purpose of M&V.  Best practice in CCS sees M&V as a component of risk management\, with the challenge being to assess risk correctly and only then assign technologies for its management. This is particularly difficult in the area of environmental monitoring\, where CCS will occur within dynamic and evolving systems where causal chains are notoriously difficult to pin down. In this talk I will explain how to approach M&V as a part of managing the risks of CCS projects\, and suggest a definition of its scope.

SUMMARY:PESA WA April Technical Lunch:  From Liability to Asset - The Role of Mature Wells in Carbon Capture and Storage and the REX-CO2 well screening tool
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             \nPESA WA invites you to our technical luncheon on Thursday 18th April.\nFrom Liability to Asset: The Role of Mature Wells in Carbon Capture and Storage and the REX-CO2 well screening tool \nPresented by Siddiq Mahyildin (IKON Science – Technical Sales Geoscientist) \n\nThe UK Continental Shelf (UKCS) boasts significant CO₂ storage potential\, which is important in the context of the UK’s commitment towards Net Zero emissions targets. Since many of the basins in the UKCS are regarded as mature there is now an increasing emphasis towards plug and abandonment rather than further exploration. In this webinar\, we will explore the opportunity that exists to re-purpose near end-of-life wells and fields for use in CO₂ storage operations. Re-use as an alternative to plugging and abandonment could potentially result in significant cost savings. \nIkon Science completed the presented work with BGS for the Re-Using Existing wells for CO₂ storage operations project (REX-CO₂)\, which is an R&D initiative funded through Accelerating CCS Technologies (ACT) programme. The project aims to evaluate potential for re-purposing existing oil and gas wells that penetrate prospective CO₂ storage reservoirs. A screening methodology and software tool has been developed\, and is applied to two UKCS case studies; a depleted gas field and a saline aquifer structure. Determinations of subsurface pore pressure\, fracture pressure and seal capacity are integral to the analysis. The procedure for acquisition of regional data\, determination of production and depletion impacts\, and estimation of seal capacity are considered along with considerations for partial well abandonment. Some challenges for re-use assessments of wells on the UKCS will also be highlighted. Special thanks to John Williams (British Geological Survey). \n  \nTicket Prices: \nMember (Early Bird): $69.00 \nConcession Member [Retired\, Graduate or Hardship] (Early Bird): $59.00 \nStudent Member (Early Bird): $39.00 \nNon-Member: $99.00 \nMember (Non-Early Bird): $79.00 \nEarly bird pricing ends Thursday (1 week prior) at 5pm (AWST).

SUMMARY:PESA QLD Lunch: 18th April – Seismic Characterisation of Shallow Gas in the Cooper-Eromanga Basin
DESCRIPTION:This month’s PESA QLD technical lunch features Satya Mishra from Santos presenting: \n“Seismic Characterisation of Shallow Gas in the Cooper-Eromanga Basin”\nThe Technical Lunch will be held at the Brisbane Hilton Hotel\, in Room 82. \nFor detailed directions\, see explanation below. \n\n\n\nPresentation:\nSeismic Characterisation of Shallow Gas in the Cooper-Eromanga Basin\n\n\nVenue:\nHilton Hotel Brisbane\, 190 Elizabeth Street\, Brisbane QLD 4000\nRoom 82 (NOTE CHANGE FROM USUAL ROOM)\n(Detailed directions below)\n\n\nDate & Time:\nThursday\, 18th April 12:15 PM\n\n\n\n  \nPresentation Abstract: \nSeismic Characterisation of Shallow Gas in the Cooper-Eromanga Basin \nThe talk focuses on shallow-gas in the Cooper-Eromanga basin. Cooper has been a prolific gas basin for over 60 years and the overlying Eromanga basin has been predominantly Oil saturated. Thus gas discoveries in the Eromanga basin are generally termed as “shallow-gas”. The talk will look into various seismic characterisation methods that help in delineating the shallow-gas fields. In the process we will cover some of the structural and the stratigraphical seismic attribute methods that have been useful in field delineation. We will also look into the fluid characterisation methods e.g. AVO and Fluid substitution. We would venture into some in-land canyons in our own backyard and understand the unique play model associated with it. \n  \n\nTickets for the Technical Luncheon can be purchased below: \nTicket sales extended to Wednesday\, 17 April 12:00 PM – To avoid disappointment please register before that date and time. \n\n\n\n\nStandard Ticket Price\n\n\n\n\nPESA Members – $55\nNon-Members – $75\nStudent / Retired Members – $30\n\n\n\n\n\nThe venue location can be accessed by two means: \n1) Entry from Queen Street Mall\nTake the lifts to Level 6\, and walk to the guest lifts located in the centre of the main atrium and take the lift to Level 8. Delegates will need to turn left out of the guest lifts and walk down the hallway to Room 82. \n2) Entry from Elizabeth Street\nEnter the foyer located on 190 Elizabeth Street\, and take the lifts to Level 6 (Main Foyer).

Monitoring obligations are challenging because the injected fluid is of negligible commercial value compared to hydrocarbons\, whereas O&G operators in commercial fields have always the incentive of 4D monitoring to improve recovery\, in contrast to the generally defensive function of CCUS monitoring. Monitoring programs for CCS are invariably under pressure over costs\, mobilisation expenses\, frequency of acquisition\, and duration of obligations. This context provides incentives for lower cost methods\, and methods that might use permanent sensors to reduce survey costs.\n\nThe laws of physics describing the expected changes in geophysical responses are the same for CO2 and hydrocarbons of course\, but the unusual nature of CO2 at commercial depths makes its behaviour somewhat intermediate between methane and oil. Further\, typical injection scenarios are very unlike hypothetical reverse gas production\, and monitoring is typically focused on thin plumes driven predominantly by gravity forces. These factors make the surveillance of CO2 plumes often somewhat different in character to typical 4D oilfield workflows\, in addition to the expectations of reduced surface footprint and acquisition costs. In this talk I aim to rehearse some of the basic facts controlling the expected effect of CO2 presence on elastic and electromagnetic properties. The resulting effect of these changes on\nremotely detectable signals from controlled or passive sources will be discussed\, with particular attention to seismic\, our benchmark wavelike high-resolution method. I aim to illustrate the main findings  using published results on well-known CCUS projects. In addition\, a short survey of geophysical monitoring efforts using non-seismic methods\, such as diffusive or potential-fields methods using electromagnetic responses or geomechanics\, will further ornament the brief selection of published work.
