Numerical Simulation of CO2 Sequestration in Natural CO2 Reservoirs on the Colorado Plateau

Abstract This paper outlines the proposed research and summarizes pre-project work that forms a basis for a new research program on CO2 sequestration in saline aquifers. The pre-project work considers storage and disposal of CO2 several kilometers beneath the surface in generic aquifers and demonstrates the use of reactive chemical transport modeling to simulate mineral sequestration of CO2. The current research project applies these techniques to particular saline reservoirs on the Colorado Plateau. In a companion paper (Allis et al, these proceedings) the properties of the natural CO2 reservoirs of the Colorado Plateau are described. This is joint work by Industrial Research Ltd., University of Utah and, Utah Geological Survey funded by DOE grant #DE-FC26-00NT4096.
