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

Figure 8

Streamlines (red curves) and flood flight times (rainbow colors). (a) Domains of lower permeability result in local increase in TOF. Matrix permeability is 100 mD; rectangular central zone between injectors and producers has permeability of 20 mD. Porosity is equal in both domains (20%). (b) Increase of TOF in low permeability domain is undone when porosity in low permeability domain is adjusted from 20% to 5%. (c) Reversely, TOF can be increased still further than in (a) when porosity is adjusted from 20% to 80%.
