  1. BP CO2 Sequestration • Geology of the San Joaquin Valley • by • Terralog Technologies USA, Inc. • February 13, 2008

  2. Oil fields in the southern San Joaquin Valley; studied fields in red

  3. Cumulative oil and condensate production as of December, 2006 (DOGGR, 2007)

  4. Cumulative gas production as of December, 2006 (DOGGR, 2007)

  5. Estimated gas reserves as of December, 2006 (DOGGR, 2007)

  6. Structure of the San Joaquin Valley. NSB=Northern Sierran block; SSB=Southern Sierran block; NDH=northern Diablo homocline; WFB= westside fold belt; M-TS=Maricopa-Tejon subbasin (Bartow, 1991)

  7. (DOGGR, 1998)

  8. San Joaquin basin stratigraphic column (Scheirer & Magoon, 2007) Oil reservoir rock in green Gas reservoir rock in red Shale dashed lines

  9. Typical sand and mud deposition in submarine fan turbidite systems (Henderson, 1987

  10. Major reservoir formations in the southern San Joaquin basin, their depositional environments and lithologies

  11. Fields with production from major reservoir formations

  12. Potential Fields for CO2 Sequestration Based on potential storage capacity (pore volume), multiple target zones below 5000ft depth and presence of seals Elk Hills Belridge North Paloma

  13. Estimated pore volumes for studied fields

  14. Elk Hills Discovered 1919 2,777 wells as of 12/2006

  15. Pliocene contour map and cross section showing strucutre of Elk Hills anticlines (Fiore, et al., 2007)

  16. Miocene structure contour map (DOGGR, 1998)

  17. Cross section for Elk Hills (DOGGR, 1998)

  18. Stratigraphic column for Elk Hills

  19. Potential CO2 targets and seals for Elk Hills

  20. Belridge North Discovered in 1912 1072 wells as of 12/2006

  21. Structure contour map for the Oligocene of Belridge North (DOGGR, 1998)

  22. Cross section and stratigraphy for Belridge North (DOGGR, 1998)

  23. Extent of diatomite reservoir, North and South Belridge fields

  24. Potential CO2 target zones and seals for Belridge North

  25. Paloma Discovered in 1939 28 wells as of 12/2006

  26. Structure contour map for the upper Miocene of the Paloma oil field

  27. Cross section of the Paloma field (DOGGR, 1998)

  28. Stratigraphy for the Paloma field

  29. Potential CO2 target zones and seals for the Paloma field

  30. CONCLUSIONS Extensive regional shales and thick, lenticular sand bodies in multiple fields Based on potential storage volume estimated from pore volume for producing zones at >5000ft depth, candidate fields for CO2 sequestration include: Elk Hills Belridge North Paloma
