11 Risk Management in all Phases 11 Characterization Design Construction Operation Old wells Verification Injection

12 Storage Fundamentals Capacity: (match to source & estimate plume shape) bulk volume (seismic) X porosity (logs) X storage factor Injectivity (how many wells) permeability from core, log & well test Containment (caprock integrity, fractures, wellbore integrity, faults) 3000 ft 12? CO 2 Post injection 5 miles 3500 to 9000 ft 500MW ~ 100MT ~ 100square miles

13 Storage Fundamentals The Big Picture 13 Capture plant plot s 500MW ~ 100MT ~ 100square miles 10 Miles

14 Oilfield Activity in North America 14 Inject 41 MtCO2/yr for enhanced oil recovery Output of six 1000-Mw coal-fired plants Moved safely hundreds of miles via pipeline 50 oilfields that produce >150,000 bbl fluid per day Output of a 1000-Mw coal-fired plant No huge technical barriers to geological storage of CO2. But...monitoring in EOR is for the oil, not the CO2.

19 Early Success 19 Pick the Right Site Non-complex, depth, porosity, perm, extent, structure, caprock Some existing wells, but not many Access and capability for: 3-D seismic acquisition, logs, core, fluids, background Use the Right Technology Proper density, resolution, noise limits, area of review Value equivalent uncertainty reduction Has impact on performance and risk Properly Integrate t the Data Requires an experienced, skilled, multi-disciplinary team. Unified modeling environment Shared earth model, easily updatable - Living i

20 Summary 20 Non-technical factors are the key to progress Clear regulatory guidelines and and long term liability protection are needed for commercial involvement. Resource requirements will be large Uncertainties can be managed with technology Technology must be valued Proper baseline characterization ti is the key to reducing cost number of wells, frequency of monitoring, public acceptance
