1. BP CO2 sequestration • December 7, 2007 Presentation • by • Terralog Technologies USA, Inc.

2. Meeting Objectives:    Present overview of project efforts to date on evaluation of CO2 sequestration candidates in the southern San Joaquin Valley Discuss and agree on go-forward workplan

4. 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)

5. (DOGGR, 1998)

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

8. Midway-Sunset Belridge South Kern River Cymric Elk Hills Buena Vista Lost Hills McKittrick Mount Poso Kern Front Coles Levee North Edison Belridge North Fruitvale Rio Bravo Greeley Yowlumne Round Mountain • For each field: • Geology • Wells and Development History • Production History and Data • Potential Capacity for CO2 Sequestration • Structure Contour Map • Cross Section • Composite Well Log and Stratigraphic Column

9. Example: Elk Hills Structure contour map showing field structure of three anticlines Cross section showing fault separation between each anticline

10. Elk Hills stratigraphic column and well log Lowermost production from Carneros Ss

11. Producing Zones in the Elk Hills field

14. Estimated Saline Aquifer Capacity

15. Workplan Additional research on geology and evolution of San Joaquin Valley Complete field reviews, including identification of sequestration targets and capacities Summarize historical production Describe geology and sequestration potential of saline aquifers Compare potential sequestration candidates
