Grid Design and Scale up of Geological Heterogeneity

• Geological heterogeneity is often represented by assigning rock properties to grids of
  different block size. Some geological features are represented as discrete objects at the
  chosen grid block size and others are represented as continuous properties. There is a
  transition between the discrete and continuous where the size of the features is too
  small to be represented discretely and too large to be represented continuously. This is
  linked to the notion of REV, that is, it is impossible to choose a grid size where geological
  features are at REV scale. An extended view of modeling regimes is proposed by
  modifying the classical REV plot presented by Bear. The challenge of geostatistical
  modeling in transition regime is addressed. A continuous framework is considered with
  particular attention to the spatial continuity since the scale of variability is larger than
  the scale of modeling. Numerical experiments are conducted on various geological
  models.
