Rules for Flight Paths and Time of Flight for Flows in Porous Media with Heterogeneous Permeability and Porosity

Figure 10

Impact of permeability anisotropy on FP and TOF. Streamlines (red curves) and flood flight times (rainbow colors). (a) Permeability in the horizontal -direction equals 100 mD while permeability in the vertical -direction equals 20 mD. (b) Permeability in the -direction equals 100 mD while permeability in the -direction equals 500 mD. Porosity is uniform and equal in both simulations (20%).
