Presentation Transcript

  1. Field Studies on CO2 Monitoring • In Salah (Algeria) 2004 –. Commercial-scale. Gas reservoir. Test-bed for CO2 monitoring technologies ($30mm Research project)

  2. In Salah Monitoring * Iain Wright (CO2 Project Manager, BP Group Technology) EU-OPEC CCS Conference, Riyadh, September 21st 2006

  3. Pre-cursor 3D

  4. Sleipner (Norway) 1996 – 2006. Commercial-scale. Saline formation. 4-D seismic surveys: 1994, 1999, 2001, 2002, 2005

  5. Weyburn (Canada). 2000 -. Commercial-scale, Oil reservoir, EOR. Seismic monitoring: 4-D surveys, microseismic, horizontal-horizontal cross-well, 3D VSP

  6. * Don White (Geological Survey of Canada)

  7. Some Other Field/Pilot Scale Tests • Snohvit (Norway 2006) • Otway (Australia) • K12B • Kansas Geological Survey's 4-D Seismic Monitoring of CO2 Injection project (Hall-Gurney Field ) • The Frio Brine Pilot experiment • Rio Vista Gas Reservoir • Teapot • Lost Hill, CA • CO2 monitoring at a pilot-scale CO2 injection site in Nagaoka, Japan • West Pearl Queen reservoir • Pembina Cardium, Alberta, Canada • ……

  8. Lab Studies of CO2 Properties • Knight and Nolen-Hoeksema (GRL, 1990)

  9. (The original figure)

  10. Wang, Gates, & Langan (Geophysics, 1998)

  11. Myer (Lawrence Berkeley National Lab) 2001 Changes in P-wave velocity for Berea sample saturated with 1.1 Ω–m brine and then flooded with CO2 at 300 psi.

  12. Salehi, Gowelly & Batarseh (Gas Technology Institute) 2006

  13. Compressional wave velocity under gas and water saturation

  14. Conclusions • Seismic is the key technology for CO2 monitoring • Current seismic monitoring projects were done with conventional seismic methods • Special seismic methods should be developed for CO2 monitoring • A pilot-scale experiment to verify long-term, low cost monitoring concept that has been studied with our simulations • Using our design in In Salah or an EOR field
