We studied the uncertainties in the predictions of supercritical CO 2 plume behavior and leakage potentials within heterogeneous media. For this purpose, hypothetical heterogeneous field with different geostatistical features were developed. The heterogeneous field represents a weakly non-stationary field, in which the geostatistical patterns of the mid-depth geology are similar. Two conditional non-parametric geostatistical simulation models, the Sequential Indicator Simulation, SISIM, and Generalized Coupled Markov Chain, GCMC, were applied for the stochastic characterizations. Then, predictive CO2 plume migration simulations based on multiple stochastic realizations were performed and summarized.
