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

Figure 2

Example  1: Illustration of possible misinterpretation of faster water breakthrough. Streamlines are tracked in blue and red curves are the time of flight contours spaced for 0.25 years. Water breakthrough takes 1 year in a priori model (a) but the posterior observation shows breakthrough occurs already after half a year (b).
