摘要

Away from the wells, interpolation methods are used to populate reservoir models with petrophysi-cal properties such as porosity and permeability. These methods proceed by estimating the property values at a given location in the reservoir. That estimation depends on how strongly the rock material at the location of interest is correlated to surrounding data. Interpolation techniques use measures of spatial correlation, inferred from observations that are functions of the 'deposition' distance between two (or more) locations. However, today, distances between sediment particles are very different from what they were at the time these particles were deposited, In order to approximate original distances, algorithms rely on transformations implied by the geometry of 'stratigraphic' grids used to represent 3D subsurface reservoir models. These transformations map the grids into regular Cartesian grids of equal cell dimensions assumed to be the space of deposition or 'parametric' space.
