Reactive Multiphase Behavior of Co{sub 2} in Saline Aquifers Beneath the Colorado Plateau

[摘要] Field and laboratory investigations of naturally occurring CO{sub 2}-reservoirs are being conducted to determine the characteristics of potential seal and reservoir units and the extent of the interactions that occur between the host rocks and the CO{sub 2} charged fluids. Efforts have focused on the Farnham Dome, located in central Utah, and the Springer-St. Johns field in Arizona and New Mexico. The Springer-St. Johns field is particularly significant because of the presence of extensive travertine deposits that document release of CO{sub 2} to the atmosphere. CO{sub 2} accumulations at both fields occur in sedimentary rocks typical of CO{sub 2} reservoirs occurring on the Colorado Plateau. The main achievements were: (1) to assess the possibility of CO{sub 2} leakage from the Farnham Dome of central Utah; and (2) prepare a paper for presentation at the 3rd Annual Conference on Carbon Sequestration.
