Advanced Modeling Methods in Carbon Dioxide Sequestration - I

McPherson, B., University of Utah

The reactive transport process of sequestering carbon dioxide in geologic formations is complicated. The physical processes involved are dissolution of carbon dioxide in brine, transport and trapping of free gas and brine and complex mineralogical reactions between carbon dioxide, brine and rocks of given composition. Gas adsorption, desorption and multiphase flow are the most relevant mechanisms when coalbeds are used for storage. This session will address advanced modeling issues related to storage of carbon dioxide in underground formations. Modeling heterogeneities and parameter uncertainties, model validation, upscaling laboratory scale information and flow and transport in faults and fractures would be some of the topics considered.
