Description
Heterogeneity could be called the "beast" of subsurface modeling. We know that it exists, but often we disregard it because of the complexity of properly handling it. After a quick recall of the importance of heterogeneity in subsurface modeling, we analyze the progression of gravity currents in heterogeneous media under different kinds of heterogeneity, more precisely, multiGaussian realizations, sedimentary-like realizations. The analysis focuses on the time evolution of the free surface as a dense liquid enters a reservoir filled with a much lighter liquid. Probability maps of this surface are built, which measure the uncertainty on the current evolution, and they are compared with the evolution of the same current with a homogeneous conductivity equal to the geometric mean of the heterogeneous realizations.
