  1. Statoil’s R&D onCO2 Capture and Storage European Forum Gas in Paris on 12-13 September 200710 years of CO2 Storage Tore A Torp, Statoil Research Centre, Trondheim, Norway

  2. 10 years of CO2 Storage CONTENT: • “Low Carbon Diet” • Industrial Experiences with CO2 • Sleipner, In Salah, K12B, Ketzin, Snohvit and ??? • What will Authorities and Public demand? • Industrial deployment soon? • VISION and Way forward?

  3. Vision

  4. Sleipner CO2-injection:- Decided in 1992- In operation since 1996- 1 million tones CO2/yearTime Magazine,17. Mai 2004

  5. Previous Experiences with CO2 & Injection • Enhanced Oil Recovery (Texas, Hungary, Turkey, Brazil,Croatia) • Natural gas cleaning • Transport – Pipelines & Ships • Natural gas re-injection • Natural gas underground storageand • Beer & soft drinks, dry cleaning, food packaging – Every day life

  6. Yara CO2-tankers, 1500 m3 capacity

  7. The Sleipner field – CO2 Treatment and Injection

  8. The Utsira Formation

  11. 1996 1999 2001 3D Seismic surveys at Sleipner

  12. Time-lapse seismic datasets of CO2 stored in Utsira formation

  13. Plume extension & top Utsira time map 1 km CO2 distribution June 2006 • 8,4 million tones had at the time of seismic data acquisition been injected over 10 years • Plume area: 2,8 km2 (1,3 km2 in 2001) • Plume long axis: 3760 m • Maximum distance from injection point: 2560m • Plume limitation: • UTM E: 437950 – 439550 • UTM N: 6470000 - 6473660 • The plume reached a northern saddle point between 2002 and 2004 • Maximum speed of front since 2004: 250 m/year, in a NNE direction • Distance from CO2 to wells: • Exploration well 15/9-13: 430m, decreasing about 12 m/year • D-template: about 2 km straight west of northern plume • 15/9-19 wells: about 4,5 km north of plume saddle 3,76 km Injection point 15/9-13 Seismic section Plume outline June 2006 430m Plume outline Oct 2001 Amplitude maps of the uppermost horizon, in 2001 (left), 2004 (middle) and 2006 (right). Hot colors represent higher amplitudes and thicker CO2 accumulation.

  14. Simulated picture of the distribution of CO2 after three years. Radius of largest bubble 800 m and the total plume 200 m high. Ref: SINTEF Petroleum 2001

  15. SACS Project 1998-2002 WHAT WE DID ACHIEVE: • 3D Seismic proven, Gravimetry tested • Reservoir simulation tools partly proven • Geology and Geochemistry of “Utsira” mapped • Reason to expect the CO2 to stay for thousands of yearsDOCUMENTATION • “SACS Best Practice Manual, 1.version.” • Download from www.co2store.org, see page “SACS”.

  16. CO2STORE – the case studies Midt Norge (Mid-Norway), NGU in cooperation with SINTEF, Industrikraft MidtNorge and Statoil The Sleipner field Kalundborg, Denmark. GEUS in cooperation with Energi E2 Valleys, Wales. BGS in cooperation with Progressive Energy Schwarze Pumpe, Germany. BGR in cooperation with Vattenfall

  17. Demonstration K12-B Injection of CO2 In a depleted gas field Operator: Gaz de France PRODUCTION NEDERLAND B.V.

  18. Snøhvit, the next field to implement CO2 storage

  19. Depth: 330 m 160 km Snøhvit – All subsea

  20. The Snøhvit CO2 Injection

  21. Towards Large Scale Implementation? T R U S T NASCENT CO2SINK GeoCapacity GESTCO Hypogen Storage? CO2STORE Storage CO2ReMoVe CASTOR-S SACS - Pipeline - Ship CO2NET Transport OK! ULCOS C O ST Hypogen Coal? CASTOR-C DYNAMIS DYNAMIS CCP Grace Capture CACHET ENCAP Hypogen Gas? 2006

  22. Demonstrations of CO2 storage SLEIPNER SNØHVIT WEYBURN KETZIN IN SALAH FRIO BRINE Nagaoka K12B GORGON Source: IEA GHG

  23. Trapping and Leakage Trapping Mechanisms • Containment • Micro-pore trapping • Dissolution in water • Mineral binding Leakage ways? • WELLS • Faults/Cracks • Underground mobility

  24. Environmental impacts Main potential LOCAL impacts: • Humans and animals – if concentrated • Plants – if in root systems • Soil • Sea bottom – More R&D! Natural analogues: • Natural CO2 seeps (vulcanoes) • Under sea vents

  25. What will the Authorities demand? • Access rights and Licence • Site characterisation and Plan • Monitoring & Verification • Reporting to UNFCC and ETS • Remediation? • Decommissioning and ”Hand shake” • Monitoring until “stability”?

  26. What will the Public demand? • Safe operation • No leakage • Monitoring & Verification in full openness • Acceptance from UNFCC and ETS • Long term stability

  27. HALTEN CO2 Project - Statoil & Shell industrial realization

  28. Mongstad CHPw/CO2-plant Plant for CO2-capture

  29. Reduce capture COST: Technologies exists Another chemical factory Extra investment and energy consumption Costs too high for industry  NEED NEW TECHNOLOGY Build TRUST in storage: Is it staying there long enough? Experience and large scale demo Experience from EOR and storage Oil&gas methods and tools works Geology varies from site to site  MORE DEMO SITES Need two legs to walk !
