3. The Southwest Carbon Sequestration Partnership • In all partner states: • major universities • geologic survey • other state agencies • lead organization: NMT • as well as • Western Governors Association • five major utilities • seven energy companies • three federal agencies • the Navajo Nation • many other critical partners

4. Southwest Carbon Project Objectives • Phase I: • Characterize SW region carbon sources and sinks • Identify the best options by linking carbon sources to carbon sinks • Phase II: • Demonstrate these options with field tests Figure compliments of Rick Allis, UGS

5. Southwest Carbon Project Objectives Note: the minimum GHG reduction goals for the region would be met if we simply supplant the natural CO2 in the Colorado-to-Texas pipelines with anthropogenic CO2! Figure compliments of Rick Allis, UGS

6. Southwest Carbon Project Themes • Geologic systems • - Potentially large volume • Terrestrial systems • - Rapid implementation • Mineralization • still not mature technology • potentially very large volume • safety / risks known • expensive

7. Best Demonstration Options Four of over 100 geologic options were selected as the most promising opportunities for evaluation: combined enhanced oil recovery and deep brine reservoir sequestration testing, Paradox Basin, Utah 1,2 3 4 September, 2006 150,000 tons/year Southwest Regional Partnership on Carbon Sequestration
