Grid Design and Scale up of Geological Heterogeneity

  • Author / Creator
    Razavi, Seyedehfatemeh
  • 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.
