“…Some researchers have looked at the sensitivity of numerical multiphase flow models to variations in selected petrophysical parameters due to heterogeneity when modeling geologic storage of CO 2 (Han et al, 2011;Doughty, 2010;Sifuentes et al, 2009;Juanes et al, 2006;Mo and Akervoll, 2005). Variations in the costs of carbon capture, transport, and storage have also been investigated (Heath et al, 2012;Middleton et al, 2012;Poiencot et al, 2012;Cinar et al, 2008;McCoy and Rubin, 2009). However, to the authors' knowledge no other study has systematically varied the full suite of petrophysical parameters required for numerical modeling of geologic CO 2 sequestration and used the outputs to evaluate the relative impact on injection costs.…”
