The Groundwater and Storage interactions project arose out of a meeting on the shoulder of the Greenhouse Gas Technologies Conference in Amsterdam in 2010. It was decided to concentrate initially on the Australian Flagships projects. On 3 May 2011 Australian researchers and government agencies met and presented their work to date.

In these slides the Carbon Transport and Storage Company (CTSCO) present on the Surat Basin Hydrogeology and related issues.

Transcript

  • 1. CTSCO:a carbon storage solutionSurat Basin Hydrogeology-related Issues3 May 2011Commercial in Confidence
  • 2. Wandoan IGCC with CCSProject summary Power Plant & CO2 Capture• Located in Surat Basin, Queensland• Proposed IGCC with up to 90% CCS (341 MW sent out capacity)• ~2.5Mt CO2 pa, at 1-2 km’s Stanwell Corporation & GE Energy underground• Project integrates partners’ strengths – GE IGCC and pre-combustion capture technology CO2 Transport & Storage – Stanwell power portfolio experience – CTSCo storage program development• Fuel supply by Xstrata Coal Xstrata Coal subsidiaryCommercial in Confidence 2
  • 3. Project strengths Well defined fundamentals:  Operating and warrantied IGCC technology  90% capture capability from day 1  Surat strategy identified early  Fuel supply tested and selected  Grid Connection Enquiry lodged  Water and gas supply available  Efficient development spend  Commercially fundable  Preferred tenderer status for 3 storage tenements within 200kms (>75Mt)Commercial in Confidence 3
  • 4. Timely proving up of CO2 storagerequires innovation Storage target approach Regional Surat Basin hub potential 2,900 Mt capacity Non potable aquifer and anticline storage options targeted to reduce risk Extensive existing seismic and deep well data already available Targeting best skills with many years specific resource experience The challenge – to deliver: Faster assessment timeframes Lower assessment risk Lower assessment costCommercial in Confidence 4
  • 5. Go to the Surat Basin Drill a deep hole Find some pore spaceCommercial in Confidence 5
  • 6. Precipice 58-0 Sand Isopach (m)Commercial in Confidence 6
  • 7. CTSCo Objectives 1. To deliver a successful outcome from the CCS Flagship funding = industrial-scale CO2 injection demonstration project, that: – Is technically feasible – Is safe to operate and co-exist with landowners – Causes no environment harm – Is responsive to community concerns – Can help open up the basin for hub storage 2. To enable the Department of Environment & Resource Management (EPA) to issue the necessary approvals to: – Inject CO2 stream for pilot and long-term injectionCommercial in Confidence 7
  • 8. CTSCo Objectives 3. To support the development of an effective Leakage Liability and Legislative regime that underpins the commercial realities 4. Share the information freely => Enable all stakeholders to take comfort in the risk, acceptability, liability of CO2 injection at industrial-scaleCommercial in Confidence 8
  • 9. CTSCo Strategies1. Understand the technical issues (capacity, injectivity & containment) – Regional and locally consistent hydrogeological model that informs the Dynamic Reservoir Simulation – Gaps • What is the volume of CO2 required to be injected to be “Monitor-able and Verify-able”? • How will the CCS Operator “show” the plume is contained and not channelling to a leak point?2. Understand and focus on the concerns of the regulator(s) – Engage with the Regulators early in the Injection Planning/approvals process – Gaps • What is the permissible GHG Stream composition? – BTEX – NOx, SOx etc • What is the volume of CO2 required to be injected to satisfy regulators?Commercial in Confidence 9
  • 10. CTSCo Strategies 3. Staged and Gated CO2 injection testing with effective M&V to resolve concerns and deliver increasing confidence to all Stakeholders to proceed to industrial-scale storage operationsCommercial in Confidence 10
  • 11. CTSCo Hydrogeology - Lessons learned• Multiple GAB studies done but no common database• Little integration by “hydro-consultants” between – Shallow groundwater focus – Deep aquifers by “hydro-consultants” (no-one asked about DSTs, correlations etc)• Unconstrained & out-of-context comments feed concerns of non-technical CCS “gatekeepers” – Statistics based on number of wells rather than the location in the aquifer (shallow or deep wells) – Unqualified statements e.g. rate of movement 200m/y to 0.1m/y without saying where or why• Needs skills that covers deep petroleum data types and shallow groundwater systems – DST Pressure interpretation – DST water recovery – chemistry QC – Use consistent aquifer correlationsCommercial in Confidence 11
  • 12. What do we need? Reactive Chemistry Reactive Chemistry Hydrogeology Hydrogeology Geomechanics Geomechanics Dynamic Plume Simulation Dynamic Plume Simulation • Robust linkage between models • At site-specific and regional scaleCommercial in Confidence 12
  • 13. What else do we need to do?• Need to gather site-specific data (data gap analysis) – Water chemistry – Aquifer pressure, temperature – Reservoir and seal lithology, mineralogy• Need to engage with regulators early – Regional – Site specific• Need to know how we will demonstrate to regulators the impact of CO2 on aquifers and all potential stakeholders – Pressure impact – Aquifer chemistry impact – Seal integrity – Extent of actual plume movement versus predicted• Need the credibility of an expert Third Party (not CCS-aligned) to explain GAB and CO2 storage to Public• Need to maximise opportunities for co-operation => CGICommercial in Confidence 13
  • 14. Carbon Geostorage Initiative• Jonathan Hodgkinson (Geological Survey of Queensland )Commercial in Confidence 14
  • 15. Project support• Projects of this kind need support and the project wishes to acknowledge the following parties: Wandoan IGCC with CCS funding support The project has received pre-feasibility funding from the Australian Government (as part of the Clean Energy Initiative), the Queensland Government and the Australian Coal Association Coal 21 fund. The views expressed in this presentation are not necessarily the views of these parties. Project support – CO2CRC (our lead research organisation) – CSIRO (our principle research organisation in gasification) – Xstrata CoalCommercial in Confidence 15
  • 16. Uniquely Capable Proponents • One of the world’s leading technology developers • >300,000 people in over 120 countries • 60+ years of gasification experience • GE technology generates >25% of world’s power • Invests >US$2B annually in cleaner technologies “ecomaginaton” • Queensland based developer, owner and operator of power generation and coal resources • 3GW under management and dispatch to the NEM • Vested interest and experience in power and carbon markets • World’s largest thermal coal exporter and 5th largest miner • Headquarters in Australia • Extensive geological development experience and capability • Major contributor to COAL 21 voluntary industry fundCommercial in Confidence 16
